## Tenancy Change Log - December 9, 2025

## Summary
This document tracks all changes made to the multi-tenancy system during the current staging session and the last 2 commits (4d13a570 and 72d0b6b0).

---

## 🔥 Critical Fixes - December 9, 2025

### Fixed
- User swapping/logout issue - Redis sessions, no-cache auth backend, session integrity checks
- useNavigate/useLocation HMR errors - Single Suspense boundary for Routes

### Added
- Custom `NoCacheModelBackend` authentication backend to prevent user object caching
- Session integrity validation in middleware (stores/verifies account_id and user_id per request)

### Changed
- Session storage from database to Redis cache (`SESSION_ENGINE = 'django.contrib.sessions.backends.cache'`)
- React Router Suspense from per-route to single top-level boundary

---

## 🔧 Recent Session Changes (Uncommitted)

### 1. Authentication & Signup Flow
**Fixed: JWT Token Generation in Registration**
- **Issue**: Users were immediately logged out after signup because tokens weren't being returned
- **Root Cause**: Two separate `register` endpoints existed - one in `AuthViewSet` (unused) and one in `RegisterView` (actual endpoint)
- **Fix**: Updated `RegisterView` in `backend/igny8_core/auth/urls.py` to generate and return JWT tokens
  ```python
  # Added token generation to RegisterView
  access_token = generate_access_token(user, account)
  refresh_token = generate_refresh_token(user, account)
  # Return tokens in response data
  ```
- **Files Changed**: `backend/igny8_core/auth/urls.py`
- **Impact**: Users now stay logged in after successful registration

**Enhanced: Frontend Token Extraction**
- **Issue**: Frontend couldn't parse tokens from backend response structure
- **Fix**: Added multiple fallback paths in `authStore.ts` to handle nested response structure
  ```typescript
  // Handle both data.tokens.access and data.data.tokens.access
  const newToken = tokens.access || responseData.access || data.data?.tokens?.access
  ```
- **Files Changed**: `frontend/src/store/authStore.ts`

### 2. Payment Confirmation Modal
**Fixed: Invoice Amount Display**
- **Issue**: Amount showing as "PKR 0.00" in payment confirmation modal
- **Root Cause**: Frontend expected `total` field but backend returned `total_amount`
- **Fix**: Updated invoice API to return both fields for compatibility
  ```python
  'total': str(invoice.total),  # Alias for compatibility
  'total_amount': str(invoice.total),
  ```
- **Files Changed**: 
  - `backend/igny8_core/business/billing/views.py`
  - `frontend/src/components/billing/PaymentConfirmationModal.tsx`
  - `frontend/src/components/billing/PendingPaymentBanner.tsx`

### 3. Payment Approval Workflow
**Fixed: Manual Status Change Not Triggering Account Activation**
- **Issue**: When admin changed payment status to "succeeded" in Django admin, it didn't activate account or add credits
- **Root Cause**: `save_model()` only set `approved_by` but didn't run the full approval workflow
- **Fix**: Enhanced `save_model()` in `PaymentAdmin` to trigger complete workflow:
  - Update invoice status to 'paid'
  - Activate subscription status to 'active'
  - Activate account status to 'active'
  - Add credits based on plan
  - Prevent duplicate credit transactions
- **Files Changed**: `backend/igny8_core/modules/billing/admin.py`
- **Impact**: Admins can now manually approve payments in Django admin with full automation

### 4. Site Creation Permissions
**Fixed: Site Creation Failing Due to Permission Issues**
- **Issue**: Users couldn't create sites and were getting logged out
- **Root Cause**: 
  1. `SiteViewSet.get_permissions()` wasn't properly returning instances
  2. Domain field validation rejected empty strings
- **Fixes Applied**:
  - Updated `get_permissions()` to return instantiated permission classes
    ```python
    return [IsAuthenticatedAndActive(), HasTenantAccess(), IsEditorOrAbove()]
    ```
  - Modified domain validation to accept empty/None values
    ```python
    if not value or value.strip() == '':
        return None
    ```
- **Files Changed**: 
  - `backend/igny8_core/auth/views.py`
  - `backend/igny8_core/auth/serializers.py`
