## 🏗️ Core Architectural Principles
|
||
|
||
### 1. **Log-Free Codebase Policy** 🚫📝
|
||
**Policy**: Zero `log::` statements in main/development branches
|
||
|
||
**Implementation**:
|
||
- Developers may use `log::` for troubleshooting in feature branches
|
||
- All logs must be removed before merging to main/development
|
||
- Automated cleanup: `find src -name "*.rs" -exec perl -i -pe 'BEGIN{undef $/;} s/\s*log::[^;]*;//g' {} \;`
|
||
|
||
**Benefits**:
|
||
- Clean, production-ready code
|
||
- Simplified AI-assisted development
|
||
- Reduced file complexity and size
|
||
- Eliminated performance overhead
|
||
|
||
### 2. **Builder Pattern Architecture** 🏗️
|
||
**Philosophy**: Single-source-of-truth construction for all complex objects
|
||
|
||
**Core Builders**:
|
||
- `SessionDataBuilder`: UserPersistentData construction
|
||
- `ConfigurationBuilder`: Environment variable access
|
||
- `ResponseBuilder`: HTTP response handling
|
||
- `ServiceFactory`: Service instantiation
|
||
|
||
#### **ResponseBuilder Pattern - Critical Frontend Integration** ⚠️
|
||
**IMPORTANT**: All API responses are automatically wrapped by ResponseBuilder
|
||
|
||
**Response Structure**:
|
||
```json
|
||
// Backend Controller Code:
|
||
ResponseBuilder::ok().json(serde_json::json!({
|
||
"success": true,
|
||
"last_payment_method": "credit_card"
|
||
})).build()
|
||
|
||
// Actual API Response (wrapped by ResponseBuilder):
|
||
{
|
||
"data": {
|
||
"success": true,
|
||
"last_payment_method": "credit_card"
|
||
},
|
||
"success": true
|
||
}
|
||
```
|
||
|
||
**Frontend Compatibility Pattern**:
|
||
```javascript
|
||
// ✅ CORRECT - Handle ResponseBuilder wrapping
|
||
const response = await fetch('/api/endpoint');
|
||
const result = await response.json();
|
||
const data = result.data || result; // Handle both wrapped and unwrapped
|
||
|
||
if (data.success && data.field) {
|
||
// Use data.field
|
||
}
|
||
|
||
// ❌ INCORRECT - Direct access fails with ResponseBuilder
|
||
if (result.success && result.field) {
|
||
// This fails because actual data is in result.data.field
|
||
}
|
||
```
|
||
|
||
**Implementation Examples**:
|
||
- **Orders**: `data.data.orders` (nested due to ResponseBuilder + order response structure)
|
||
- **Payment Methods**: `data.last_payment_method` (single ResponseBuilder wrapping)
|
||
- **Wallet Balance (Navbar dropdown)**: `data.wallet_balance_formatted` and `data.display_currency` from `/api/navbar/dropdown-data`
|
||
- **Wallet Balance (direct API, if used)**: `data.balance` or similar numeric field; always unwrap via `const data = result.data || result;`
|
||
|
||
**Key Rules for AI Coders**:
|
||
1. **Always use**: `const data = result.data || result;` for API responses
|
||
2. **Test both**: Wrapped and unwrapped response structures
|
||
3. **Debug with**: `console.log('API response:', result);` to see actual structure
|
||
4. **Remember**: ResponseBuilder adds automatic `{"data": {...}, "success": true}` wrapper
|
||
|
||
### CSP-Compliant Frontend: External JS + JSON Hydration (2025-08-11)
|
||
|
||
**Policy**: Zero inline scripts and zero inline event handlers. All page behavior lives in external JS with JSON hydration blocks.
|
||
|
||
**Implementation**:
|
||
- Externalized base and page scripts to `src/static/js/` (e.g., `base.js`, `wallet.js`, `statistics.js`).
|
||
- Added `{% block scripts %}{% endblock %}` in `src/views/base.html` for page-specific includes.
|
||
- Pages provide a `<script type="application/json" id="...">` hydration block. All injected values are server-rendered and must use `json_encode` to produce valid JSON under CSP.
|
||
|
||
**Hydration example (wallet)**:
|
||
```html
|
||
<script type="application/json" id="wallet-hydration">
|
||
{"currency_symbol": {{ currency_symbol | default(value='$') | json_encode() }}}
|
||
</script>
|
||
```
|
||
|
||
**Recent Fix (root cause of server exit)**:
|
||
- Tera failed to parse `src/views/wallet/index.html` due to invalid filter usage inside JSON and quoting issues.
|
||
- Fixed by using the named-arg form `default(value='$')` and emitting JSON via `json_encode()`.
|
||
- Added explicit Tera init logging in `src/main.rs` so startup errors print to stderr:
|
||
- File: `src/main.rs` → log `Tera initialization error: {e}` before exiting.
|
||
- Outcome: `cargo run --bin projectmycelium` now keeps the Actix server running; template errors are clearly reported.
|
||
|
||
**Benefits**:
|
||
- Security: Strict CSP compliance (no inline code) reduces XSS risk.
|
||
- Maintainability: Clear separation of structure (HTML), data (hydration JSON), and behavior (external JS).
|
||
- Performance: External JS is cacheable across pages; smaller HTML payloads.
|
||
- Testability: Hydration data is deterministic JSON; easier unit/integration tests.
|
||
- Consistency: One binding pattern via `DOMContentLoaded` and data attributes, not scattered inline handlers.
|
||
|
||
**Rules of use**:
|
||
- Never use `onclick`/`onchange` in templates; bind events in JS on `DOMContentLoaded`.
|
||
- Always emit hydration via `<script type="application/json" id="...">` and parse it in JS.
|
||
- Always `json_encode` any value rendered into hydration JSON; prefer named-arg filters (e.g., `default(value='...')`).
|
||
|
||
**Files updated**:
|
||
- `src/static/js/base.js` (navbar/cart globals), `src/static/js/wallet.js`, `src/static/js/statistics.js`, `src/static/js/checkout.js`, `src/static/js/services.js`.
|
||
- `src/views/base.html` (external scripts block), `src/views/wallet/index.html` (hydration block fix), `src/views/marketplace/checkout.html`, `src/views/marketplace/services.html`.
|
||
- `src/main.rs` (Tera initialization error logging for startup diagnostics).
|
||
|
||
**Next steps to complete CSP externalization**:
|
||
- Externalize remaining inline handlers across marketplace and dashboard templates (cart/checkout/orders/services, pools, user, farmer, service_provider, invoice/report print buttons) using per-page JS and hydration.
|
||
- Replace inline `window.print()` with a shared print utility and bind via `data-action="print"`.
|
||
- Audit all hydration blocks to use `json_encode` and provide `{}` when no data is needed.
|
||
|
||
#### Services Page Externalization — Completed 2025-08-11
|
||
|
||
- Removed all inline scripts and `onclick`/`onchange` handlers from `src/views/marketplace/services.html`.
|
||
- Added CSP-safe hydration block: `<script type="application/json" id="services-data">{}</script>` and stable container id `id="services-grid"`.
|
||
- Implemented `src/static/js/services.js` to bind `.add-to-cart-btn` clicks, show auth modal on 401, listen for `serviceCreated` events, and render service cards without inline handlers.
|
||
- Integrates with `base.js` globals when present (`updateCartCount`, `emitCartUpdated`).
|
||
|
||
#### Dashboard Orders Page Externalization — Completed 2025-08-11
|
||
|
||
- Removed all inline scripts and event handlers from `src/views/dashboard/orders.html`.
|
||
- Added CSP-safe hydration block `#orders-hydration` with per-field JSON encoding:
|
||
|
||
```html
|
||
<script type="application/json" id="orders-hydration">
|
||
{
|
||
"currency_symbol": {{ currency_symbol | default(value='$') | json_encode() }},
|
||
"display_currency": {{ display_currency | default(value='USD') | json_encode() }}
|
||
}
|
||
</script>
|
||
```
|
||
|
||
- Included external script: `src/static/js/dashboard_orders.js`.
|
||
- Event delegation via `data-action` attributes:
|
||
- `toggle-details`, `view-invoice`, `contact-support`, `view-invoice-from-modal`.
|
||
- ResponseBuilder compatibility handled in JS: `const payload = result.data || result;`.
|
||
- Tera parse fix: replaced quoted defaults inside JSON with named-arg defaults and `json_encode()` per field to emit valid JSON; resolved the startup error “expected a value that can be negated or an array of values”.
|
||
|
||
#### ✅ CSP Externalization COMPLETE — 2025-08-12
|
||
|
||
**ACHIEVEMENT**: The entire Project Mycelium is now 100% CSP-compliant with zero inline handlers across all templates.
|
||
|
||
**Dashboard Service Provider Externalization — COMPLETED**:
|
||
- Removed inline handlers for availability and service creation in `src/views/dashboard/service_provider.html` by using `data-action` attributes and external JS.
|
||
- Implemented delegated handlers in `src/static/js/dashboard-service-provider.js`:
|
||
- `availability.toggle` → `toggleAvailability()` for checkbox changes (no API write).
|
||
- `availability.update` → `updateAvailability()` PUT `/api/dashboard/availability` with validation and notifications.
|
||
- `services.create` → `createNewService()` opens modal, validates, submits to API, and refreshes lists.
|
||
- Fixed and initialized `loadAvailabilitySettings()` on `DOMContentLoaded` to hydrate UI safely under CSP.
|
||
- Added delegated handler: `data-action="services.saveChanges"` → calls existing `saveServiceChanges()` for the Save Changes button (no inline JS).
|
||
- Hydration: confirmed CSP-safe JSON block `#sp-dashboard-hydration` present and parsed in initialization.
|
||
- Tera parse fix applied to `src/views/dashboard/service_provider.html`: moved page-specific styles to `{% block head %}` and hydration/external scripts to `{% block scripts %}` at the top level; `dashboard_content` now contains only markup/modals.
|
||
|
||
**Final CSP Cleanup — COMPLETED 2025-08-12**:
|
||
- ✅ `src/views/cart.html` — Converted `editCartItem()` & `removeCartItem()` to `data-action="cart.edit"` & `data-action="cart.remove"`
|
||
- ✅ `src/views/dashboard/user.html` — Converted `viewBookingDetails()` & `contactProvider()` to `data-action="booking.view"` & `data-action="provider.contact"`
|
||
- ✅ `src/views/dashboard/farmer.html` — Converted 6 inline handlers to data-action patterns:
|
||
- `refreshSliceCalculations()` → `data-action="slice.refresh"`
|
||
- `syncWithGrid()` → `data-action="grid.sync"`
|
||
- `viewNodeSlices()` → `data-action="node.view"`
|
||
- `setMaintenanceMode()` → `data-action="node.maintenance"`
|
||
- `restartNode()` → `data-action="node.restart"`
|
||
|
||
#### Create Service Modal Flicker — Root Cause Fix (2025-08-12)
|
||
|
||
- __Root cause__: Background elements (cards, rows, service items) had broad `transition: all` and hover effects. During `.modal.fade`, these hover transitions triggered expensive repaints, causing visible flicker on modal buttons.
|
||
- __Fix__: Preserve Bootstrap fade while eliminating repaint conflicts.
|
||
- Tighten transitions to specific properties (e.g., `box-shadow`, `transform`, `background-color`).
|
||
- Suppress hover-driven transitions while any modal is open via `body.modal-open` rules (reset transforms/box-shadows/bg-color to static values).
|
||
- Restore `.modal.fade` on `#createServiceModal` to keep smooth animation.
|
||
- Add light GPU compositing hints on modal buttons (`will-change`, `transform: translateZ(0)`, `backface-visibility: hidden`).
|
||
- Verified single-initialization for delegated handlers and Enter-key submit prevention on modal forms.
|
||
- __Files changed__: `src/static/css/styles.css`, `src/views/dashboard/service_provider.html`.
|
||
|
||

|
||
|
||
#### Tera JSON Hydration & Template Safety Guidelines (Must Read)
|
||
|
||
To avoid Tera parse errors and ensure CSP-safe, valid JSON in hydration blocks, follow these rules:
|
||
|
||
- __Always encode each field individually__
|
||
- Use: `{{ value | default(value=...) | json_encode() }}` per field.
|
||
- Strings: use named-arg defaults, e.g., `default(value='USD')`.
|
||
- Optionals: use `default(value=null)` to produce `null`.
|
||
- Note: Avoid `default(value=none)` as some template contexts can treat `none` as an unresolved variable. If in doubt, prefer explicit `null` or guard with `{% if var is defined %}{{ var | json_encode() }}{% else %}null{% endif %}`.
|
||
|
||
- __Do NOT create an object literal inside a single interpolation__
|
||
- Don’t: `{{ { "user_currency": user_currency, "cart_details": cart_details } | json_encode }}`
|
||
- This can trigger: “expected a value that can be negated or an array of values”.
|
||
|
||
- __Recommended pattern for hydration blocks__
|
||
- Build the JSON shape literally and encode each field:
|
||
|
||
```html
|
||
<script type="application/json" id="checkout-hydration">
|
||
{
|
||
"user_currency": {{ user_currency | default(value='USD') | json_encode() }},
|
||
"cart_details": {{ cart_details | default(value=none) | json_encode() }}
|
||
}
|
||
</script>
|
||
```
|
||
|
||
- __When to use `safe`__
|
||
- `type="application/json"` blocks are not executed; JSON encoding avoids HTML escaping.
|
||
- `safe` is typically unnecessary if you encode each field. If you emit one fully-encoded JSON string, you may append `| safe`.
|
||
|
||
- __General Tera tips__
|
||
- Prefer named arguments in filters: `default(value='...')`.
|
||
- Never mix template control structures inside JSON literals.
|
||
- Log startup errors: we print Tera init errors in `src/main.rs` to surface issues early.
|
||
- Validate JSON quickly by copying the block into a linter when in doubt.
|
||
|
||
__Checkout fix (2025-08-11)__: `src/views/marketplace/checkout.html` switched from a single interpolated object to the per-field encoding pattern above, resolving the runtime Tera parse error.
|
||
|
||
#### Tera Block Structure – Common Pitfall (Fixed 2025-08-12)
|
||
|
||
Tera blocks cannot be nested inside other blocks. Child templates must keep structural blocks (`head`, `scripts`) at the top level and place page markup inside the content block only.
|
||
|
||
- __Do__:
|
||
- Put page styles inside `{% block head %}...{% endblock %}`.
|
||
- Put hydration JSON and external JS includes inside `{% block scripts %}...{% endblock %}`.
|
||
- Keep `dashboard_content` (or `content`) limited to HTML and modal markup only.
|
||
|
||
- __Don't__:
|
||
- Nest `{% block scripts %}` or style blocks inside `dashboard_content`.
|
||
|
||
- __Recent fix__: `src/views/dashboard/service_provider.html` raised an "unexpected `{% endblock %}`" parse error due to nested blocks. We refactored by moving:
|
||
- Styles → top-level `{% block head %}`
|
||
- Hydration JSON (`#sp-dashboard-hydration`) and external JS includes → top-level `{% block scripts %}`
|
||
- Result: Tera parses cleanly; CSP structure is preserved.
|
||
|
||
### DevX: Rust Error-Only Compilation Logs — Added 2025-08-12
|
||
|
||
To streamline debugging and keep output readable, we added a small toolchain to capture only Rust compiler errors (no warnings) from `cargo check`:
|
||
|
||
- **Script**: `scripts/dev/cargo-errors.sh`
|
||
- **Make targets**:
|
||
- `make check-errors`
|
||
- `make fixtures-errors` (runs with fixtures env)
|
||
- **Output**: `/tmp/cargo_errors_only.log` (override with `OUT=/path/to/file.log`)
|
||
- **Dependencies**: Prefers `jq` for precise filtering; falls back to a sed/awk parser if `jq` is not installed.
|
||
|
||
Usage examples:
|
||
|
||
```bash
|
||
# Standard
|
||
make check-errors
|
||
|
||
# Fixtures mode
|
||
make fixtures-errors
|
||
|
||
# Custom output path
|
||
OUT=/tmp/my_errors.log make check-errors
|
||
|
||
# Quick count/peek
|
||
grep -c '^error' /tmp/cargo_errors_only.log
|
||
sed -n '1,80p' /tmp/cargo_errors_only.log
|
||
```
|
||
|
||
Behavior:
|
||
- Suppresses warnings entirely; logs only error diagnostics.
|
||
- Returns `cargo check` exit code (non‑zero when errors present), so it fits CI or hooks.
|
||
- Color is disabled via `CARGO_TERM_COLOR=never` to keep the log clean.
|
||
|
||
### 3. **Persistent Data Only** 💾
|
||
**Policy**: No mock data in production code
|
||
- All data operations use `user_data/` directory
|
||
- Real user data drives marketplace content
|
||
- MockDataService completely eliminated
|
||
|
||
#### **User-Centric Data Storage Pattern** 🎯
|
||
**Architectural Decision**: Orders stored as part of user's persistent data (`UserPersistence`)
|
||
- **Localized Source of Truth**: Each user owns their complete data set
|
||
- **Industry Standard**: Follows GDPR compliance and data portability requirements
|
||
- **Implementation**: Orders stored in `UserPersistentData.orders` vector
|
||
- **Data Flow**: Purchase → UserPersistence → API → ResponseBuilder → Frontend
|
||
- **Benefits**: Simplified data management, easier account operations, better user privacy
|
||
|
||
**Order Management Implementation**:
|
||
- `instant_purchase.rs`: Orders pushed to `persistent_data.orders` vector
|
||
- `order.rs`: `get_user_orders()` reads from UserPersistence, sorts by `created_at` DESC
|
||
- `orders.html`: Frontend handles nested ResponseBuilder JSON structure (`data.data.orders`)
|
||
- **ResponseBuilder Compatibility**: All API responses wrapped in `{"data": {...}, "success": true}`
|
||
|
||
#### Marketplace Order Invoices (2025-08-09)
|
||
- Endpoint: `GET /orders/{id}/invoice` renders an HTML invoice view for printing.
|
||
- Controller: `OrderController::get_order_invoice` in `src/controllers/order.rs`.
|
||
- Ownership check prefers `session["user_email"]` for user identity.
|
||
- Dual-source order retrieval: first check in-memory `OrderStorage`; if not found, fallback to persistent `UserPersistence` (email-based). This fixes buy-now invoice access.
|
||
- Template: `src/views/marketplace/order_invoice.html` renders order id, date, items, qty, unit price, line totals, subtotal/total, payment method, billing email, and includes a Print button.
|
||
- Frontend UI: `src/views/dashboard/orders.html` opens the HTML view in a new tab.
|
||
- CTA text changed to "View Invoice" with eye icon.
|
||
- JS handlers renamed: `downloadInvoice` → `viewInvoice`, `downloadInvoiceFromModal` → `viewInvoiceFromModal`.
|
||
- Not implemented (by design): direct download API (`/api/orders/{id}/invoice`).
|
||
- Rationale: Current UX uses "View Invoice" + browser Print → Save as PDF; avoids extra dependencies/complexity; no immediate need for programmatic downloads. Can be added later if integrations require it.
|
||
|
||
#### Service Requests and Bookings Flow — Current Status and Fix Plan (2025-08-14)
|
||
|
||
• Current state
|
||
- Providers can create services; buyers can purchase them.
|
||
- Buyer sees entries under “My Service Requests” (`/dashboard/user`).
|
||
- Provider sees entries under “Service Requests” (`/dashboard/service-provider`).
|
||
- Provider lookup/persistence fixed: requests saved under correct provider file.
|
||
|
||
• Issues observed
|
||
- Status mismatch: when provider accepts (In Progress), buyer still sees Pending.
|
||
- View CTA error: “Cannot read properties of undefined (reading 'id')” (likely envelope/shape mismatch).
|
||
- Update CTA causes the request to disappear (tab filtering not refreshed or destructive overwrite/mock fallback).
|
||
- Buyer booking details view shows only a success button (insufficient detail rendering).
|
||
|
||
• Backend actions
|
||
- Synchronize status updates across users:
|
||
- In `DashboardController::update_service_request_progress` (and `update_service_request`), update both:
|
||
1) Provider `service_requests` in `user_data/{provider}.json`.
|
||
2) Buyer `service_bookings` in `user_data/{buyer}.json`.
|
||
- Use stable identifiers: `request.id`, `customer_email`, and optionally `linked_booking_id`.
|
||
- Ensure non-destructive in-place updates via `UserPersistence` (find by id; mutate fields; keep others).
|
||
- Add structured logs: before/after counts, updated ids, file paths; bubble errors.
|
||
- Normalize details endpoints to a consistent DTO and ResponseBuilder envelope:
|
||
- `GET /api/dashboard/service-requests/{id}/details`, `.../completed-details`, `.../report` → return `{ success, data: { id, status, product, customer_email, ... } }`.
|
||
|
||
• Frontend actions
|
||
- Always unwrap API with `const data = result.data || result;` and reference `data.id`.
|
||
- After updates, re-render tables and migrate rows between tabs (Pending → In Progress → Completed) instead of removing.
|
||
- Improve buyer “My Service Bookings” details to render provider/product/status timeline.
|
||
- Guard null/undefined records and missing properties.
|
||
|
||
• Testing
|
||
- E2E: provider creates → buyer purchases → provider accepts.
|
||
- Assert provider request status and buyer booking status both advance to In Progress.
|
||
- API contract tests: details endpoints include `id` and consistent field names.
|
||
|
||
• Observability
|
||
- Add structured logging to update endpoints and persistence helpers to trace ids, counts, and file paths during updates.
|
||
|
||
#### Progress Update — Service Requests & Bookings (2025-08-14 13:35)
|
||
|
||
- Removed inline mock `client_requests` arrays in `src/models/user.rs` (replaced with `Vec::new()`), aligning with the persistent‑data‑only policy and fixing compile errors from new fields.
|
||
- Confirmed `ServiceRequest` includes `hours_worked: Option<f64>` and `notes: Option<String>` with `#[serde(default)]`; all construction sites initialize them (e.g., `src/services/order.rs` sets `None`).
|
||
- Controllers `dashboard::update_service_request` and `dashboard::update_service_request_progress` now normalize responses via `ResponseBuilder`, reload the updated request, and synchronize the buyer’s `service_bookings` with the provider’s `service_requests`.
|
||
- Persistence (`UserPersistence`): added/used helpers to update buyer booking fields; persist `hours_worked` and `notes`; set `completed_date` when status is Completed or progress ≥ 100.
|
||
- Build status: `cargo check` passes; only warnings remain (unrelated to this flow).
|
||
|
||
Next:
|
||
- Remove remaining inline mocks (e.g., `revenue_history`) and source exclusively from persistent storage.
|
||
- Audit update paths to ensure `APP_ENABLE_MOCKS=0` has zero mock fallbacks.
|
||
|
||
#### Progress Update — Service Provider Dashboard Persistent Data (2025-08-15 08:46)
|
||
|
||
- Template refactor: `src/views/dashboard/service_provider.html` now binds exclusively to injected persistent context `service_provider_data` (e.g., `active_services`, `total_clients`, `monthly_revenue_usd`). Removed all `user.mock_data.service_provider_data.*` references.
|
||
- Hydration: The `#sp-dashboard-hydration` JSON block outputs the persistent `service_provider_data` using `json_encode()` for CSP-safe parsing.
|
||
- Frontend JS: `src/static/js/dashboard-service-provider.js` aligned to persistent USD fields (`monthly_revenue_usd`, `total_revenue_usd`, `price_per_hour_usd`). Fallback init payload keys updated to `*_usd`. ResponseBuilder unwrap pattern enforced (`const data = result.data || result;`). Removed legacy/mock field usage.
|
||
- Backend controller: `DashboardController::service_provider_section` constructs and injects persistent `ServiceProviderData` via `UserPersistence` (summary metrics, services, client requests). No mock fallbacks remain. Placeholder series like `revenue_history` are empty-by-design, not mock-driven.
|
||
- Verification: `cargo check` passes; manual dashboard UI test under `APP_ENABLE_MOCKS=0` confirms cards, tables, and charts render from persistent data/hydration.
|
||
|
||
Next:
|
||
- Apply the same persistent-only mapping to `/dashboard/app-provider` and `/dashboard/user` (templates + JS + controller sections). Ensure `*_usd` naming in UI logic and remove any `user.mock_data` access.
|
||
- Replace/remove any remaining placeholder arrays (e.g., `revenue_history`) with persisted metrics or clearly mark as not-yet-implemented (no mock values).
|
||
|
||
#### Progress Update — App Provider Dashboard Persistent Data (2025-08-15 10:30)
|
||
|
||
- Frontend JS (`src/static/js/dashboard-app-provider.js`):
|
||
- Removed legacy `monthly_revenue` fallbacks and any `sessionStorage` merges; all revenue logic uses persistent `*_usd` fields only (e.g., `monthly_revenue_usd`).
|
||
- Treated deployment status "Running" as "Active" for UI consistency.
|
||
- Exposed `window.__appProviderDashboard` for modal helpers to estimate revenue.
|
||
- Updated deployment details modal to use estimated deployment revenue derived from app-level revenue.
|
||
- Backend (`src/controllers/dashboard.rs`):
|
||
- Fixed `GET /api/dashboard/deployment/{id}` to return proper JSON success/failure envelopes via `ResponseBuilder`.
|
||
- `json_to_app` helper reads `monthly_revenue_usd` with a soft fallback to legacy `monthly_revenue` for backward compatibility.
|
||
- Verification: UI tested under `APP_ENABLE_MOCKS=0`; charts, tables, and modals source only persistent data. ResponseBuilder unwrap pattern enforced on the frontend.
|
||
|
||
#### Progress Update — Dashboard Overview Activities Mapping — COMPLETED (2025-08-15 10:30)
|
||
|
||
- Root cause: `src/views/dashboard/index.html` referenced `activity.date`, but backend provided `UserActivity` without a `date` field, causing a Tera render error.
|
||
- Fix: In `src/controllers/dashboard.rs`, map `UserActivity` into a template-friendly `recent_activities` table with fields:
|
||
- `date`: formatted from `timestamp` as `%Y-%m-%d %H:%M`
|
||
- `action`: derived from `ActivityType` (e.g., Login, Purchase, Deployment, ...)
|
||
- `status`: from `metadata.status` when present; defaults to `Active` for deployments, otherwise `Completed`
|
||
- `details`: from `description`
|
||
- Outcome: `/dashboard` renders successfully with persistent activities. No template changes required; context now matches template expectations.
|
||
|
||
#### Progress Update — Mock Gating & Status Normalization (2025-08-15 12:41)
|
||
|
||
- Backend: Gated legacy mock initialization in OAuth flow. `src/controllers/gitea_auth.rs` now attaches `MockUserData::new_user()` only when `APP_ENABLE_MOCKS` is enabled via `get_app_config().enable_mock_data()`.
|
||
- Model/Docs: Normalized deployment status nomenclature to “Active”. Updated `src/services/slice_calculator.rs` comment from "Running" → "Active" for deployment status examples.
|
||
- Build: `cargo check` passing after changes (warnings only).
|
||
|
||
Recent related changes:
|
||
- Mock data normalization: In `src/models/user.rs` mock `DeploymentStat` for "Enterprise AI Suite", status was changed from "Running" → "Active".
|
||
- Frontend demo: `src/static/js/demo-workflow.js` emits "Active" in simulated `deploymentStatusChange` events.
|
||
|
||
Next:
|
||
- Audit all controllers for unconditional mock usage (e.g., `src/controllers/dashboard.rs`) and gate behind `APP_ENABLE_MOCKS`.
|
||
- Normalize remaining "Running" → "Active" across:
|
||
- Rust builders: `src/models/builders.rs` (`DeploymentStatBuilder` default status)
|
||
- Frontend: `src/static/js/marketplace-integration.js`, `src/static/js/dashboard-user.js`
|
||
- Templates: any status badge strings
|
||
- Run `cargo test` and perform manual UI verification with `APP_ENABLE_MOCKS=0`.
|
||
|
||
#### User Data Loading & Scan Hardening — COMPLETED 2025-08-14 15:29
|
||
|
||
• Problem
|
||
- Multiple modules scanned `user_data/` broadly and attempted to parse non-user fixture files (e.g., `session_data.json`, carts, aggregated fixtures), causing serde parse errors and runtime failures.
|
||
|
||
• Design Decision
|
||
- Enforce a strict, uniform filter for per-user JSON files across the entire codebase.
|
||
- Criteria for a valid user file:
|
||
- Filename ends with `.json`
|
||
- Filename contains `_at_` (email encoding)
|
||
- Filename does NOT contain `_cart`
|
||
- Filename is not `session_data.json`
|
||
|
||
• Implementation (Rust)
|
||
- Updated directory scans to apply the filter in:
|
||
- `src/services/node_marketplace.rs` → `get_all_marketplace_nodes()`, `get_all_slice_combinations()`
|
||
- `src/services/node_rental.rs` → `find_node_owner()`
|
||
- `src/services/order.rs` → `find_app_provider()`, `find_service_provider()`
|
||
- `src/controllers/dashboard.rs` → deployment counting logic
|
||
- `src/utils/data_cleanup.rs` → `DataCleanup::cleanup_all_users()`
|
||
- `src/utils/data_validator.rs` → `DataValidator::validate_all_user_files()`
|
||
- Confirmed existing aggregators in `src/services/user_persistence.rs` already applied equivalent filtering for services/apps/products.
|
||
|
||
• Behavior & Guarantees
|
||
- Only real per-user files are parsed; non-user fixtures are ignored.
|
||
- Eliminates deserialization errors and runtime crashes from non-user files.
|
||
- Provider dashboard data accesses go through `UserPersistence`; no production mock fallbacks (`APP_ENABLE_MOCKS=0`).
|
||
|
||
• Build & Verification
|
||
- `cargo check` passed after changes.
|
||
- Integration tests that parse user JSON remain valid; further E2E will confirm dashboard stability.
|
||
|
||
#### Insufficient Balance – Unified Error Contract (2025-08-09)
|
||
- Decision: Standardize the API error response for insufficient funds across checkout, buy-now, and cart-related validations.
|
||
- Status Code: Recommend 402 Payment Required as the single status for insufficient funds. If current implementations differ, document and migrate to 402.
|
||
- Canonical Response (via ResponseBuilder):
|
||
```json
|
||
{
|
||
"success": false,
|
||
"error": {
|
||
"code": "INSUFFICIENT_FUNDS",
|
||
"message": "Insufficient balance",
|
||
"details": {
|
||
"currency": "USD",
|
||
"wallet_balance_usd": 0,
|
||
"required_usd": 0,
|
||
"deficit_usd": 0
|
||
}
|
||
}
|
||
}
|
||
```
|
||
- Apply in:
|
||
- Controllers/Services that perform funds checks: `src/controllers/order.rs`, `src/services/order.rs`, `src/services/instant_purchase.rs`
|
||
- Wallet-dependent controllers: `src/controllers/wallet.rs`, `src/controllers/pool.rs`, `src/controllers/rental.rs`
|
||
- Frontend Guidance:
|
||
- Consume `error.details` to render a consistent message: "Insufficient balance. Need $<deficit> more." (currency-aware)
|
||
- Do not hardcode numbers; read from `details`. Maintain `const data = result.data || result;` wrapper tolerance.
|
||
- Testing:
|
||
- API tests: assert status code and JSON shape for checkout and buy-now flows (and cart validations if applicable).
|
||
- UI tests/steps: verify consistent rendering and clear CTAs (e.g., "Add Funds").
|
||
- Compatibility:
|
||
- If legacy shapes exist, document temporary adapter logic and a removal timeline.
|
||
|
||
### Product Data Architecture: User-Owned Products & Derived Catalog (2025-08-10)
|
||
**Decision**: Products are owned by the creating user (single source of truth). The marketplace catalog is a derived read model. Avoid dual writes.
|
||
|
||
- Single Source of Truth (now): user-persistent storage via `UserPersistence` (per-user JSON) holds canonical product records owned by that user (`provider_id`/`user_email`).
|
||
- Catalog (read model): `ProductService` aggregates user-owned products (and fixture seeds in fixtures mode), dedupes by `id`, and derives categories at runtime. Do not write to the catalog directly.
|
||
- Fixtures Mode: `user_data/products.json` is seed/demo-only and not a write target. Optionally, a dev-only generated cache `user_data/catalog.products.json` may be produced by an indexing task and must be marked as generated.
|
||
- Implemented: id-based deduplication in `ProductService::get_all_products()` prevents overlap between seeds and user-owned items. Later sources override earlier ones to honor the SOT.
|
||
- Consistency: `ProductService::get_product_by_id()` now queries the aggregated, de-duplicated catalog to ensure the same precedence rules apply to detail views.
|
||
|
||
#### Category ID Normalization (Fixtures) — 2025-08-10
|
||
- Rationale: Historical fixture data used plural/alias category IDs that did not match frontend filters/routes.
|
||
- Implementation: During fixture load, `ProductService` normalizes category IDs to canonical singular forms (e.g., "applications" → "application", "gateways" → "gateway").
|
||
- Data Hygiene: `user_data/products.json` is updated to store singular `category_id` values.
|
||
- Outcome: All marketplace category views (`/marketplace/applications`, `/marketplace/gateways`, etc.) display the correct products.
|
||
|
||
#### Provider → Marketplace → Consumer Flow — Implemented 2025-08-12
|
||
- Creation (Provider)
|
||
- Service/App creation via dashboard APIs:
|
||
- Services: `GET/POST /api/dashboard/services`, `PUT /api/dashboard/services/{id}`, `DELETE /api/dashboard/services/{id}`
|
||
- Apps: `GET/POST /api/dashboard/apps`, `PUT /api/dashboard/apps/{id}`, `DELETE /api/dashboard/apps/{id}`
|
||
- Generic products: `GET/POST /api/dashboard/products`
|
||
- Persistence: `UserPersistence` writes to `user_data/{email}.json` under `products` (single source of truth).
|
||
- Aggregation (Marketplace)
|
||
- `src/services/product.rs::ProductService::get_all_products()` aggregates fixtures + user products (+ optional slice products) and de-duplicates by `id`.
|
||
- Category normalization applied uniformly via `canonical_category_id` (see below).
|
||
- Optional dev TTL cache controlled by `APP_CATALOG_CACHE` and `APP_CATALOG_CACHE_TTL_SECS`.
|
||
- Visibility (Consumer)
|
||
- `src/controllers/marketplace.rs::MarketplaceController::services()` filters by canonical categories `service` and `application`, converts prices to user currency, and injects `service_products` into `src/views/marketplace/services.html`.
|
||
- Template contract: Each entry is `{ product, price, formatted_price }`. Page is CSP-compliant with JSON hydration and external JS (`src/static/js/services.js`).
|
||
- Purchase Flows
|
||
- Add to Cart: `POST /api/cart/add` → `OrderController::add_to_cart`.
|
||
- Buy Now:
|
||
- Affordability: `GET /api/wallet/check-affordability?amount=<Decimal>`
|
||
- Instant Purchase: `POST /api/wallet/instant-purchase`
|
||
- ResponseBuilder envelope: Frontend unwraps with `const data = result.data || result;`.
|
||
- Generalization
|
||
- App providers follow the same flow; canonical `application` category is normalized and displayed on `/marketplace/applications` with equivalent pricing and purchase behaviors.
|
||
|
||
#### Category Normalization (User Products) — 2025-08-12
|
||
- Problem: Providers historically saved subcategory IDs (e.g., `Consulting`, `Deployment`) causing products to be filtered out of `/marketplace/services`.
|
||
- Solution: `src/services/product.rs::canonical_category_id` maps professional service subcategories (Consulting, Deployment, Support, Training, Development, Maintenance) to canonical `service`.
|
||
- Result: User-created services stored in `user_data/{email}.json` are visible post-aggregation; controller still tolerates both `service` and `application` during transition.
|
||
|
||
#### Catalog Dev Cache (Development) — 2025-08-10
|
||
- Purpose: Speed up local development by caching the aggregated catalog derived from fixtures, user-owned products, and optional slice combinations.
|
||
- Implementation: In-memory TTL cache inside `ProductService` keyed by `include_slice_products`.
|
||
- Structure: `static CATALOG_CACHE: OnceLock<Mutex<CatalogCache>>` holding two buckets (with/without slices).
|
||
- Entry: `CacheEntry { products: Vec<Product>, fetched_at: Instant }`.
|
||
- Behavior: `get_all_products()` checks TTL and returns cached vector; on miss/expiry, recomputes via `aggregate_all_products_uncached()` and stores new entry. De-duplication semantics are preserved.
|
||
- Configuration:
|
||
- Flags: `APP_CATALOG_CACHE` (true/false), `APP_CATALOG_CACHE_TTL_SECS` (u64 seconds).
|
||
- Defaults: Development/Test enabled with TTL=5s; Production disabled unless explicitly enabled.
|
||
- Accessors: `AppConfiguration::is_catalog_cache_enabled()` and `catalog_cache_ttl_secs()`.
|
||
- Scope & Consistency:
|
||
- Caches only the aggregated catalog vector; downstream helpers (e.g., categories) continue to derive from that consistent list.
|
||
- Slice toggle maintains distinct caches; category normalization and id-based dedupe remain intact.
|
||
- Invalidation & Non-goals (Phase 0):
|
||
- No write-through invalidation yet; rely on small TTL for freshness during dev.
|
||
- Manual bust options: restart the server or wait for TTL to lapse. Changing env TTL requires restart to take effect.
|
||
- Code pointers: `src/services/product.rs::ProductService::get_all_products()`, `aggregate_all_products_uncached()`; configuration in `src/config/builder.rs`.
|
||
- Generated artifacts: If you generate `user_data/catalog.products.json`, keep it out of VCS (e.g., add to `.gitignore`).
|
||
- Acceptance:
|
||
- Manual test: results update after TTL; no duplicate products; category pages reflect normalized IDs.
|
||
- Build: `cargo check` passes.
|
||
- Phase Roadmap:
|
||
- Phase 0 (now): In-memory TTL cache for dev.
|
||
- Phase 1: Optional dev-only cache-bust endpoint or keyboard shortcut in debug UI.
|
||
- Phase 2: Optional fine-grained caches (by category/provider) or Redis toggle for production scalability.
|
||
|
||
#### Marketplace Overview Composition & De-duplication — 2025-08-10
|
||
- Overview Sections: The dashboard composes multiple product sections, notably "Featured Items" (curated) and "Popular Applications" (category-filtered).
|
||
- De-duplication Rule: Items already rendered in "Featured Items" are excluded from "Popular Applications" to prevent duplicate cards.
|
||
- Implementation: `src/controllers/marketplace.rs` collects featured product IDs into a set and filters the popular list prior to price conversion and render.
|
||
- Scope: De-duplication is local to the overview page; category/detail pages show full results without cross-section filtering.
|
||
|
||
#### Migration Blueprint: PostgreSQL + PostgREST
|
||
- Tables:
|
||
- `users(id uuid pk, email text unique, ...)`
|
||
- `products(id uuid pk, owner_user_id uuid fk, name text, description text, category_id text, base_price numeric(18,8), base_currency text, availability text, attributes jsonb, metadata jsonb, status text check in (draft,published,archived), created_at timestamptz, updated_at timestamptz)`
|
||
- `categories(id text pk, name text, ... )`
|
||
- Views/Indexes:
|
||
- `public_products` view exposing only `status = 'published'` rows for catalog queries
|
||
- GIN/trigram indexes on searchable text/jsonb fields for efficient search
|
||
- RLS Policies:
|
||
- Owners: `INSERT/UPDATE/DELETE` where `owner_user_id = auth.uid()`
|
||
- Public: `SELECT` from `public_products` only
|
||
- Auth via JWT (GoTrue) used by PostgREST
|
||
- Lifecycle:
|
||
- Publishing controlled by `status` (draft→published→archived), separate from `availability` (e.g., InStock/OutOfStock)
|
||
- Prefer soft-delete with audit columns over hard delete
|
||
|
||
Env/Mode Notes:
|
||
- Fixtures: `APP_DATA_SOURCE=fixtures`, `APP_FIXTURES_PATH=./user_data`, `APP_ENABLE_MOCKS=0`
|
||
- Mock (dev-only): `APP_DATA_SOURCE=mock APP_ENABLE_MOCKS=1` to visualize legacy mock data during development.
|
||
- Personas for demos: `user1..user10@example.com` with password `password` (see `docs/dev/design/current/ux/current_personas.md`)
|
||
- Manual test checklist: `docs/dev/design/current/ux/manual_fixture_test_checklist.md`
|
||
|
||
Quick .env for Phase 0 (fixtures/dev):
|
||
|
||
```dotenv
|
||
APP_DATA_SOURCE=fixtures
|
||
APP_FIXTURES_PATH=./user_data
|
||
APP_ENABLE_MOCKS=0
|
||
APP_CATALOG_CACHE=true
|
||
APP_CATALOG_CACHE_TTL_SECS=5
|
||
```
|
||
|
||
### Roadmap to Final Marketplace (2025-08-10)
|
||
Phases are incremental and shippable; each has crisp acceptance criteria.
|
||
|
||
#### Phase 0: Polish fixtures/dev mode (now–short)
|
||
- Catalog dev cache: Optional generated `user_data/catalog.products.json` from aggregator; documented as generated-only.
|
||
- Acceptance: cold-start marketplace loads ≥300 ms faster locally; cache invalidation documented.
|
||
- Mock cleanup: Ensure prod path never touches mock data/services; annotate remaining dev-only templates (e.g., mock timeline) and gate behind config.
|
||
- Acceptance: production run with `APP_ENABLE_MOCKS=0` has zero mock reads/writes.
|
||
- Tests:
|
||
- Invoices: ownership checks, 403/404, print view loads.
|
||
- Cart badge/events: add/remove/clear flows consistent after reload.
|
||
- Marketplace dashboard loads with mocks disabled (HTTP 200).
|
||
- Rental endpoints return 404 when mocks are disabled and resource is missing.
|
||
- Acceptance: tests green in CI; fixtures-run smoke passes.
|
||
|
||
#### Phase 1: Unified insufficient balance contract
|
||
- Backend: Standardize on 402 Payment Required and canonical ResponseBuilder error payload across `src/controllers/order.rs`, `src/services/order.rs`, `src/services/instant_purchase.rs`, and wallet-related controllers.
|
||
- Reference: See prompt doc `docs/dev/design/current/prompts/prompt-1.md` — section "🔥 Critical: Insufficient Balance – Unified Error Contract" for the JSON envelope and acceptance details.
|
||
- Frontend: One renderer consumes `error.details` (e.g., “Insufficient balance. Need $X more.”).
|
||
- Acceptance: Each major purchase flow has one insufficient-funds behavior; e2e verified.
|
||
|
||
#### Phase 2: Orders API enrichment — COMPLETED 2025-08-13
|
||
- Added `invoice_available` and `invoice_url` in `/api/orders` and `/api/orders/{id}`.
|
||
- UI enables/disables invoice CTAs from payload.
|
||
- Acceptance: No dead CTAs; invoices open consistently from both list and detail.
|
||
|
||
#### Phase 3: Provider and catalog readiness
|
||
- Minimal “publishing status” on products (draft/published) respected by aggregator (fixtures treat all as published).
|
||
- Featured curation source-of-truth file (config JSON) for Featured Items, decoupled from categories.
|
||
- Acceptance: Only published items appear; Featured fully driven by config.
|
||
|
||
#### Phase 4: Search, filters, and category UX
|
||
- Add keyword search and common filters (category, price range, availability).
|
||
- Acceptance: Search/filters consistent across overview and category pages; no duplicates with Featured on overview.
|
||
|
||
#### Phase 5: Database migration (PostgreSQL + PostgREST)
|
||
- Implement schema and `public_products` view with RLS as per blueprint in this guide.
|
||
- Wire `ProductService` reads to PostgREST in “db mode”; keep fixtures mode intact for demos.
|
||
- Migration scripts + seed path for demo data.
|
||
- Acceptance: App runs in db mode with same UX; fixtures mode remains supported for demos.
|
||
|
||
#### Phase 6: Payments and wallet top-up
|
||
- Stripe integration to purchase TFC credits; lock rates at checkout; record payment method.
|
||
- Commission logic applied to marketplace orders.
|
||
- Acceptance: Successful top-up flows; orders complete with correct balances and auditable records.
|
||
|
||
#### Phase 7: Security and reliability
|
||
- CSRF, rate limiting, session hardening; structured logging where appropriate; metrics & health endpoints.
|
||
- Acceptance: Security checklist green; basic SLOs monitored.
|
||
|
||
#### Phase 8: Launch readiness
|
||
- CI/CD, load testing, PWA/performance polish, accessibility, documentation/runbooks.
|
||
- Acceptance: Go-live checklist complete; rollback plan defined.
|
||
|
||
### 4. **TFC Credits System** 💰
|
||
**Decision**: Pure ThreeFold Credits (1 TFC = 1 USD configurable)
|
||
- Eliminates complex TFP/USD conversion logic
|
||
- Industry-standard credit model (AWS/Google/Azure pattern)
|
||
- Simplified user experience and developer maintenance
|
||

|
||
|
||
### 5. Cart Count Consistency (Navbar Badge)
|
||
Backend (`src/services/order.rs`):
|
||
- `OrderService::get_cart_with_details()` cleans orphaned cart items (missing products), recomputes `item_count` from valid items, and persists cleaned carts to session and user storage.
|
||
- `remove_from_cart()`, `update_cart_item_quantity()`, and `clear_cart()` save to session and, for logged-in users, to persistent JSON under `user_data/*_cart.json`.
|
||
- `transfer_guest_cart_to_user()` merges guest items into the user cart on login and saves.
|
||
|
||
Frontend:
|
||
- Global `updateCartCount()` in `src/views/base.html` fetches `/api/cart` with `cache: 'no-store'` and updates the navbar badge.
|
||
- `window.updateCartCount` is called on `DOMContentLoaded` and on a global `cartUpdated` event.
|
||
- Pages that modify the cart call `window.updateCartCount()` and dispatch `cartUpdated` after changes.
|
||
- `src/views/marketplace/dashboard.html` uses a locally named `updateCartCountLocal()` to avoid overriding the global function.
|
||
|
||
Result: After restarts or rebuilds, the navbar badge accurately reflects the backend cart state.
|
||
|
||
### 6. Cart Clear UX (Post-Reload Success Toast)
|
||
Rationale: After clearing the cart, we force a short-delayed full page reload to guarantee a consistent empty-state UI. To preserve positive UX, a success toast is shown after the reload.
|
||
|
||
Pattern:
|
||
- Before reload (after successful DELETE /api/cart):
|
||
- Call `window.emitCartUpdated(0)` and `window.updateCartCount()` to update the navbar badge immediately.
|
||
- Set a session flag: `sessionStorage.setItem('cartCleared', '1')`.
|
||
- `setTimeout(() => window.location.reload(), 50);`
|
||
- On page load:
|
||
- In `DOMContentLoaded`, check the flag; if present, remove it and show a success toast.
|
||
|
||
Implementation:
|
||
- Guest Cart: `src/views/cart.html`
|
||
- Sets `cartCleared` flag before reload.
|
||
- On load, shows `showToast('Cart cleared', 'success')` and removes the flag.
|
||
- Dashboard Cart (logged-in): `src/views/dashboard/cart.html`
|
||
- Sets `cartCleared` flag before reload; sets `window._suppressCartLoadToast = true` to avoid false error toasts during reload.
|
||
- On load, shows `showToast('Cart cleared', 'success')` and removes the flag.
|
||
- Marketplace Cart View: `src/views/marketplace/cart.html`
|
||
- Sets `cartCleared` flag before reload.
|
||
- On load, shows local `showSuccess('Cart cleared')` and removes the flag.
|
||
|
||
Notes:
|
||
- All flows include credentials where required and handle ResponseBuilder responses safely (204/non-JSON tolerant where applicable).
|
||
- This pattern ensures both guest and logged-in users receive immediate feedback post-reload without UI flicker or mixed toasts.
|
||
|
||
### 7. Cart Fetch & Event Standardization (2025-08-09)
|
||
To ensure consistent cart state, session handling, and UI updates across all views, cart-related reads and mutations have been standardized.
|
||
|
||
- Global Event Helper:
|
||
- Use `window.emitCartUpdated(cartCount?)` instead of manually dispatching `CustomEvent('cartUpdated', ...)`.
|
||
- Global badge updater lives in `src/views/base.html` as `window.updateCartCount()` and listens to `cartUpdated`.
|
||
- Reads (`GET /api/cart`):
|
||
- Always include `{ cache: 'no-store', credentials: 'same-origin' }` to avoid stale data and ensure cookies/sessions.
|
||
- Mutations (POST/PUT/DELETE to `/api/cart` and `/api/cart/item/{id}`):
|
||
- Always include `{ credentials: 'same-origin' }`.
|
||
- Robustness:
|
||
- Tolerant JSON parsing where 204/No Content or non-JSON responses can occur.
|
||
- Affected Templates:
|
||
- `src/views/dashboard/cart.html`
|
||
- `src/views/marketplace/cart.html`
|
||
- `src/views/marketplace/cart_full.html`
|
||
- `src/views/marketplace/cart_standalone.html`
|
||
- `src/views/cart.html` (guest)
|
||
- Outcome:
|
||
- Navbar badge updates instantly and reliably across guest and logged-in flows.
|
||
- No stale reads; session credentials are sent for all cart operations.
|

||
|
||
#### Deployment Automation Pipeline
|
||
```rust
|
||
// Core deployment service structure
|
||
pub struct DeploymentJob {
|
||
pub id: String,
|
||
pub user_id: String,
|
||
pub service_spec: ServiceSpec,
|
||
pub tfc_amount: Decimal,
|
||
pub status: DeploymentStatus,
|
||
}
|
||
|
||
impl DeploymentQueue {
|
||
pub async fn process_deployment(&self, job: DeploymentJob) -> Result<(), DeploymentError> {
|
||
// 1. Calculate commission
|
||
let commission = job.tfc_amount * self.commission_rate;
|
||
let deployment_amount = job.tfc_amount - commission;
|
||
|
||
// 2. Convert TFC to TFT
|
||
let tft_amount = self.convert_tfc_to_tft(deployment_amount).await?;
|
||
|
||
// 3. Deploy to ThreeFold Grid using GridDriver
|
||
let deployment = self.grid_driver.deploy_service(&job.service_spec, tft_amount).await?;
|
||
|
||
// 4. Update user with deployment details
|
||
self.update_user_deployment(job.user_id, deployment).await?;
|
||
|
||
Ok(())
|
||
}
|
||
}
|
||

## 🔧 Decision Trail & Historical Context
|
||
|
||
### Decision #001: TFP → TFC Credits System Refactor
|
||
**Date**: 2025-08-04
|
||
**Status**: ✅ **APPROVED** - Implementation Complete
|
||
|
||
#### Problem Statement
|
||
The marketplace used a hybrid TFP (ThreeFold Points) to USD conversion system that created:
|
||
- Complex conversion logic throughout the codebase
|
||
- Confusing user experience with dual currency displays
|
||
- Maintenance overhead with exchange rate calculations
|
||
|
||
#### Solution: TFC (ThreeFold Credits)
|
||
- **Model**: 1 TFC = 1 USD (configurable)
|
||
- **Benefits**: Industry standard (AWS/Google/Azure pattern)
|
||
- **Implementation**: Global rename TFP → TFC, remove conversion logic
|
||
- **User Experience**: Simple mental model, familiar credit system
|
||
|
||
### Decision #002: Log-Free Codebase Policy
|
||
**Date**: 2025-08-05
|
||
**Status**: ✅ **IMPLEMENTED** - 881+ logs removed
|
||
|
||
#### Rationale
|
||
- Production-ready code should not contain debug logging
|
||
- Simplified AI-assisted development and code analysis
|
||
- Reduced file complexity and compilation overhead
|
||
- Industry best practice for clean codebases
|
||
|
||
### Decision #003: Builder Pattern Architecture
|
||
**Date**: 2025-08-03
|
||
**Status**: ✅ **IMPLEMENTED** - Single source of truth
|
||
|
||
#### Benefits Achieved
|
||
- 95.8% compilation error reduction (24 → 0 errors)
|
||
- ~1,120+ lines of code reduction
|
||
- Future-proof field additions via `..Default::default()`
|
||
- Consistent patterns across entire codebase
|
||
|
||
---
|
||
|
||
### Decision #004: Multi-Currency Display with USD Settlement
|
||
**Date**: 2025-08-07
|
||
**Status**: ✅ **IMPLEMENTED**
|
||
|
||
#### Summary
|
||
- **Design**: Users can select a display currency (USD, TFC, CAD, EUR, …). All settlements occur in USD (via Stripe at a later stage).
|
||
- **Backend Support**: Added currencies in `src/services/currency.rs::CurrencyService::get_supported_currencies()`
|
||
- TFC: `Custom("credits")`, `exchange_rate_to_base = 1.0`, `decimal_places = 2`, `is_active = true`
|
||
- CAD: `Fiat`, `exchange_rate_to_base = 1.35` (placeholder), `decimal_places = 2`, `is_active = true`
|
||
- EUR: already supported
|
||
- **Controller**: Preference and listing endpoints already validate/accept these currencies.
|
||
- File: `src/controllers/currency.rs`
|
||
- **UI Fix**: Removed duplicate USD and added TFC to the currency selector.
|
||
- File: `src/views/dashboard/settings.html`
|
||
|
||
#### Rationale
|
||
- Standard e-commerce pattern: multi-currency display with single-currency settlement simplifies accounting and Stripe integration.
|
||
- Keeps USD as canonical base for pricing, accounting, and refunds.
|
||
|
||
#### Implementation Notes
|
||
- Store canonical `base_usd_amount` on orders, plus `display_currency`, `display_amount`, `rate_used`, and `timestamp` for transparency.
|
||
- Server-side conversions via `CurrencyService.convert_amount()`; do not trust client-side for totals.
|
||
- Navbar dropdown API (`/api/navbar/dropdown-data`) provides fully formatted wallet balance (`wallet_balance_formatted`) and `display_currency` for consistent UI display.
|
||
- Dashboard overview wallet section (`src/views/dashboard/index.html`) updates `#dashboardWalletBalance` and `#dashboardCurrencyCode` on load using:
|
||
- Safe unwrap pattern: `const data = result.data || result;`
|
||
- Values: `data.wallet_balance_formatted` and `data.display_currency`
|
||
|
||
#### UX Guidance
|
||
- Show both: e.g., `Total: $123.45 USD (≈ 167.89 CAD)` and note: “final charge in USD; conversions approximate.”
|
||
- On rate refresh/expiry, prompt user to accept updated totals before checkout.
|
||
|
||
#### Future Enhancements (Optional)
|
||
- Populate currency selector dynamically from `/api/currency/supported` to avoid UI/backend drift.
|
||
- Add rate locking at checkout and audit trails for exchange rates used per order.
|
||
|

|
||
|
||
### Decision #005: Externalized Dashboard Scripts & JSON Hydration
|
||
**Date**: 2025-08-11
|
||
**Status**: ✅ IMPLEMENTED
|
||
|
||
#### Summary
|
||
- Removed inline JavaScript containing template syntax from `src/views/dashboard/index.html` to eliminate template/JS lint conflicts and improve maintainability.
|
||
- Introduced a safe data hydration pattern via `<script type="application/json" id="dashboard-chart-data">` that embeds server-provided values as pure JSON.
|
||
- Moved dashboard logic (chart initialization and wallet balance updater) to `static/js/dashboard.js`.
|
||
|
||
#### Rationale
|
||
- CSP compliance and security (no inline scripts required for charts logic).
|
||
- Better caching and performance for static JS assets.
|
||
- Cleaner separation of concerns and reduced IDE false-positive lints from mixed template/JS syntax.
|
||
|
||
#### Implementation Notes
|
||
- Chart data (resource utilization, usage trends, user activity, deployment distribution) is emitted as JSON; the external JS reads and initializes charts accordingly.
|
||
- Wallet balance and display currency continue to come from `/api/navbar/dropdown-data` and are applied to `#dashboardWalletBalance` and `#dashboardCurrencyCode` at page load.
|
||
- Static asset path convention: `/static/js/...` as used elsewhere in the app.
|
||
|
||

## 🔧 Previous Session Accomplishments (2025-08-07)
|
||
|
||
### Critical Authentication & Buy-Now Flow Fix ✅
|
||
**Problem**: Users with sufficient wallet balance (e.g., $5989) were incorrectly shown "You need $X.XX more in your wallet" when attempting purchases.
|
||
|
||
**Root Cause Analysis**:
|
||
1. **Middleware Issue**: Buy-now routes were excluded from authentication checks
|
||
2. **Session Validation**: Multi-factor session validation needed enhancement
|
||
3. **ResponseBuilder Pattern Mismatch**: Frontend expected `{can_afford: true}` but backend returned `{data: {can_afford: true}, success: true}`
|
||
|
||
**Technical Solutions Implemented**:
|
||
1. **Middleware Fix** ([`src/middleware/mod.rs:197`](../../../src/middleware/mod.rs:197)):
|
||
- Removed buy-now route exclusion from authentication middleware
|
||
- Ensured all purchase routes require proper authentication
|
||
|
||
2. **Enhanced Session Validation** ([`src/controllers/auth.rs:387`](../../../src/controllers/auth.rs:387)):
|
||
- Improved auth_status endpoint with multi-factor session validation
|
||
- Added comprehensive session state checking
|
||
|
||
3. **Frontend ResponseBuilder Compatibility** ([`src/static/js/buy-now.js:186`](../../../src/static/js/buy-now.js:186)):
|
||
- Updated JavaScript to handle ResponseBuilder's nested response format
|
||
- Added fallback logic: `affordabilityData = affordabilityResult.data || affordabilityResult`
|
||
- Maintained backward compatibility with direct response format
|
||
|
||
4. **Debug Infrastructure** ([`src/services/instant_purchase.rs:110-130`](../../../src/services/instant_purchase.rs:110-130)):
|
||
- Added comprehensive debugging to wallet balance loading
|
||
- Enhanced error tracking for user data persistence
|
||
- Improved logging for affordability calculations
|
||
|
||
**Impact & Results**:
|
||
- ✅ **Authentication Flow**: Now properly validates users before purchase attempts
|
||
- ✅ **Wallet Balance**: Correctly reads $5989 balance for user1@example.com
|
||
- ✅ **Buy-Now Functionality**: Successfully proceeds with purchases when funds are sufficient
|
||
- ✅ **ResponseBuilder Integration**: Frontend now compatible with backend response patterns
|
||
- ✅ **User Experience**: Eliminated false "insufficient funds" messages
|
||
|
||
**Technical Debt Addressed**:
|
||
- Fixed inconsistency between ResponseBuilder pattern usage and frontend expectations
|
||
- Resolved middleware authentication gaps in purchase flow
|
||
- Established proper debugging infrastructure for future troubleshooting

## 🧩 New Findings & Required Actions (2025-08-09)
|
||
|
||
The following updates align the implementation with existing architecture and codify next steps.
|
||
|
||
### 1) Marketplace Order Invoices – Endpoints, Views, Wiring
|
||
- Backend endpoints:
|
||
- GET `/orders/{id}/invoice` → Render HTML invoice (Tera) for print/view. Implemented 2025-08-09.
|
||
- Not planned: `GET /api/orders/{id}/invoice` direct download. See rationale in "Marketplace Order Invoices (2025-08-09)"; may be added later if integrations require it.
|
||
- Controller: `get_order_invoice()` implemented in `src/controllers/order.rs` with ownership checks and invoice data assembly.
|
||
- Template: `src/views/marketplace/order_invoice.html` exists and renders order id, date, items, quantities, unit price, line totals, subtotal/total, payment method, billing email, and a Print button.
|
||
- Frontend wiring: `src/views/dashboard/orders.html` opens `/orders/{id}/invoice` in a new tab; CTA text "View Invoice"; handlers renamed: `downloadInvoice` → `viewInvoice`, `downloadInvoiceFromModal` → `viewInvoiceFromModal`.
|
||
- API contract enrichment — Implemented 2025-08-13: include `invoice_available: bool` and `invoice_url: String` (empty when unavailable) in `/api/orders` and `/api/orders/{id}` responses to drive UI state.
|
||
|
||
### 2) Insufficient Balance – Unified Error Contract
|
||
- Standard error envelope when funds are insufficient (JSON):
|
||
```json
|
||
{
|
||
"success": false,
|
||
"code": "insufficient_balance",
|
||
"message": "Insufficient balance",
|
||
"insufficient_balance": {
|
||
"required": 0.00,
|
||
"available": 0.00,
|
||
"shortfall": 0.00,
|
||
"currency": "USD"
|
||
}
|
||
}
|
||
```
|
||
- Apply consistently via ResponseBuilder in:
|
||
- `src/controllers/order.rs` (checkout/place order), `src/services/order.rs` (payment paths)
|
||
- `src/services/instant_purchase.rs` (buy-now), and any wallet-dependent controllers (`wallet.rs`, `pool.rs`, `rental.rs`) that currently emit varied structures/messages.
|
||
- Frontend handling: branch on `payload.insufficient_balance` when present and render a unified copy: "Insufficient balance. Need $X more." (shortfall with currency-aware formatting). Keep `const data = result.data || result;` pattern.
|
||
|
||
### 3) Cart Events, Cache, and Credentials – Standardization
|
||
- Event emission: use `window.emitCartUpdated(cartCount?)` everywhere instead of ad-hoc `new CustomEvent('cartUpdated', ...)`.
|
||
- Fresh reads: all `fetch('/api/cart')` calls must include `{ cache: 'no-store' }`.
|
||
- Mutations: all cart-changing requests must include `{ credentials: 'same-origin' }`.
|
||
- Rationale: avoids stale navbar badge and ensures session coherence across logged-in and guest flows. Aligns with global updater defined in `src/views/base.html`.
|
||
|
||
### 4) Mock/Fixture/Stub Data – Production Gating
|
||
- Compliance audit found residual dev-only modules/usages (e.g., `MockDataService`, selective fields in `session_manager.rs`) still present in tree. Architecture requires persistent data only for production runtime.
|
||
- Action:
|
||
- Introduce `AppConfig.enable_mock_data` flag (default: false in production). Gate any legacy mock readers/writers behind this flag; remove from production routes/services.
|
||
- Ensure product and session flows source exclusively from persistent stores in production (`user_data/` via `UserPersistence`).
|
||
- Document dev-only paths and make them opt-in for local demos/tests.
|
||
|
||
### 5) Tests & Observability
|
||
- Add integration tests covering:
|
||
- Invoice endpoints (ownership checks, HTML view, file headers, success path)
|
||
- Insufficient balance contract across checkout and buy-now endpoints
|
||
- Cart badge update: mutation → `emitCartUpdated` → global `updateCartCount()` effect
|
||
- Extend API docs to include the insufficient balance envelope and invoice routes.
|
||
|
||
- Template Engine Parity (Tera):
|
||
- In tests, initialize Tera with the same template glob as production (e.g., `src/views/**/*.html`).
|
||
- Register all custom Tera functions before configuring routes, so templates render identically in tests and production.
|
||
- Tera syntax rule: avoid parentheses around filter expressions in conditions. Use `collection | length > 0` instead of `(collection | length) > 0`.
|
||
|
||
## Buyer and Provider Dashboard Flows — Offer → Buy → Track (2025-08-13)
|
||
|
||
- Scope: buyers see purchased services in `/dashboard/user` ("My Services"); providers see incoming service requests in `/dashboard/service-provider` ("Service Requests"). Extend this pattern to all product types.
|
||
- Data model: derive from persisted orders joined with products; ownership via `buyer_id` and `seller_id`. Currency via `CurrencyService`; persistent data only (no mocks in production).
|
||
- Endpoints (ResponseBuilder JSON):
|
||
- GET `/api/dashboard/user/services/purchased?product_type=service|app|bundle|any`
|
||
- Items purchased by current user (buyer). Default `product_type=service`; `any` returns all types.
|
||
- GET `/api/dashboard/service-provider/requests?product_type=service|app|bundle|any`
|
||
- Orders where current user is seller/provider. Include order status and buyer alias/contact where available.
|
||
- Errors: mutations related to these flows must emit the unified insufficient balance envelope (see “Insufficient Balance – Unified Error Contract”).
|
||
- Payload shape (example):
|
||
```json
|
||
{
|
||
"success": true,
|
||
"data": {
|
||
"items": [
|
||
{
|
||
"order_id": "ord_123",
|
||
"product_id": "prod_abc",
|
||
"product_type": "service",
|
||
"title": "Consulting Hours",
|
||
"status": "completed",
|
||
"unit_price": { "amount": 99.0, "currency": "USD", "display": "$99.00" },
|
||
"quantity": 1,
|
||
"buyer_id": "user_b",
|
||
"seller_id": "user_a",
|
||
"purchased_at": "2025-08-13T00:00:00Z"
|
||
}
|
||
],
|
||
"currency": "USD"
|
||
}
|
||
}
|
||
```
|
||
- Frontend bindings:
|
||
- `src/views/dashboard/user.html` + `src/static/js/dashboard-user.js` render purchased services. Use `const data = result.data || result;`, tolerate empty `items`.
|
||
- `src/views/dashboard/service_provider.html` + `src/static/js/dashboard-service-provider.js` render “Service Requests”.
|
||
- Use `data-action` handlers only; reads use `{ cache: 'no-store' }`; mutations use `{ credentials: 'same-origin' }`.
|
||
- Extension to all product types:
|
||
- Drive by `product_type` filter; reuse `ProductService::get_all_products()` aggregation and category normalization to surface types in the correct marketplace views.
|
||
- Acceptance:
|
||
- Buyer sees purchased services tracked in dashboard; provider sees incoming requests; consistent currency formatting and ResponseBuilder usage.
