Status:⚡ Backend core complete, manual steps remaining

---

✅ IMPLEMENTED (Backend Core Complete)

1. Payment Method Fields

Migration: backend/igny8_core/auth/migrations/0007_add_payment_method_fields.py ✅

• Added Account.payment_method (stripe/paypal/bank_transfer)
• Added Subscription.payment_method
• Added Subscription.external_payment_id
• Made Subscription.stripe_subscription_id nullable
• Added 'pending_payment' status to Account and Subscription

Models: backend/igny8_core/auth/models.py ✅

• Account.PAYMENT_METHOD_CHOICES added
• Account.payment_method field added
• Account.STATUS_CHOICES updated with 'pending_payment'
• Subscription.PAYMENT_METHOD_CHOICES added
• Subscription.payment_method field added
• Subscription.external_payment_id field added
• Subscription.stripe_subscription_id made nullable

2. Account Validation Helper

Utils: backend/igny8_core/auth/utils.py:133 ✅

• Created validate_account_and_plan(user_or_account) function
• Returns (is_valid, error_message, http_status)
• Allows: trial, active, pending_payment statuses
• Blocks: suspended, cancelled statuses
• Validates plan exists and is active

Middleware: backend/igny8_core/auth/middleware.py:132 ✅

• Updated _validate_account_and_plan() to use shared helper
• Consistent validation across all auth paths

3. API Key Authentication Fix

Authentication: backend/igny8_core/api/authentication.py:110 ✅

• Added validate_account_and_plan() call in APIKeyAuthentication
• WordPress bridge now validates account status before granting access
• Suspended/cancelled accounts blocked from API key access

4. Per-Account Throttling

Throttles: backend/igny8_core/api/throttles.py:22 ✅

• Removed blanket authenticated user bypass
• Added get_cache_key() method for per-account throttling
• Throttle keys now: {scope}:{account_id}
• Each account throttled independently

5. Bank Transfer Confirmation Endpoint

Views: backend/igny8_core/business/billing/views.py ✅

• Created BillingViewSet with confirm_bank_transfer action
• Endpoint: POST /api/v1/billing/admin/confirm-bank-transfer/
• Validates payment, updates subscription dates
• Sets account to active, resets credits
• Logs CreditTransaction

URLs: backend/igny8_core/business/billing/urls.py ✅

• Added BillingViewSet to router as 'admin'

6. Free Trial Registration

Serializers: backend/igny8_core/auth/serializers.py:276 ✅

• Updated RegisterSerializer to auto-assign free-trial plan
• Falls back to 'free' if free-trial doesn't exist
• Seeds credits from plan.get_effective_credits_per_month()
• Sets account.status = 'trial'
• Creates CreditTransaction log
• Added plan_slug and payment_method fields

Frontend: frontend/src/components/auth/SignUpForm.tsx ✅

• Removed plan loading and selection UI
• Simplified to "Start Your Free Trial"
• Removed plan_id from registration
• Redirects to /sites instead of /account/plans

Command: backend/igny8_core/auth/management/commands/create_free_trial_plan.py ✅

• Management command to create free-trial plan
• 2000 credits, 1 site, 1 user, 3 sectors

---

⏳ MANUAL STEPS REQUIRED

Step 1: Run Migration (REQUIRED)

# Must be done before deployment
docker exec igny8_backend python manage.py makemigrations
docker exec igny8_backend python manage.py migrate

Step 2: Create Free Trial Plan (OPTIONAL)

# Option A: Create new free-trial plan with 2000 credits
docker exec igny8_backend python manage.py create_free_trial_plan

# Option B: Use existing 'free' plan (100 credits)
# No action needed - code falls back to 'free'

# Option C: Update existing 'free' plan to 2000 credits
docker exec igny8_backend python manage.py shell
>>> from igny8_core.auth.models import Plan
>>> free_plan = Plan.objects.get(slug='free')
>>> free_plan.included_credits = 2000
>>> free_plan.save()
>>> exit()

Step 3: Superuser Session Fix (CRITICAL SECURITY)

Based on FINAL-IMPLEMENTATION-REQUIREMENTS.md Issue C

A. Remove Session Auth from API ViewSets Find all ViewSets and update:

# BEFORE:
authentication_classes = [JWTAuthentication, CSRFExemptSessionAuthentication]

# AFTER:
authentication_classes = [JWTAuthentication]

B. Add Middleware Superuser Detection File: backend/igny8_core/auth/middleware.py:28

# After line 28 (after skipping admin/auth):
if not request.path.startswith('/admin/'):
    if hasattr(request, 'user') and request.user and request.user.is_superuser:
        auth_header = request.META.get('HTTP_AUTHORIZATION', '')
        if not auth_header.startswith('Bearer '):
            from django.contrib.auth import logout
            logout(request)
            return JsonResponse({'success': False, 'error': 'Session auth not allowed for API'}, status=403)

C. Frontend Clear Sessions File: frontend/src/store/authStore.ts:116

logout: () => {
  // Clear all cookies
  document.cookie.split(";").forEach(c => {
    document.cookie = c.trim().split("=")[0] + "=;expires=Thu, 01 Jan 1970 00:00:00 UTC;path=/";
  });
  localStorage.clear();
  set({ user: null, token: null, refreshToken: null, isAuthenticated: false, loading: false });
},

Step 4: Docker Build Fix (STABILITY)

Based on FINAL-IMPLEMENTATION-REQUIREMENTS.md Issue D

A. Update frontend Dockerfile.dev

RUN npm ci --only=production=false
RUN rm -rf dist/ .vite/ node_modules/.vite/

B. Update docker-compose.app.yml

volumes:
  - /data/app/igny8/frontend:/app:rw
  - /app/node_modules  # Exclude from mount

C. Create rebuild script

#!/bin/bash
docker compose -f docker-compose.app.yml down
docker build --no-cache -t igny8-frontend-dev:latest -f frontend/Dockerfile.dev frontend/
docker compose -f docker-compose.app.yml up -d

Step 5: Pricing Page CTA Fix (PAID PLANS)

Based on PRICING-TO-PAID-SIGNUP-GAP.md

File: frontend/src/marketing/pages/Pricing.tsx:43

Add slug to tiers and update CTAs - see PRICING-TO-PAID-SIGNUP-GAP.md for details

📊 Database State (from CURRENT-STATE-CONTEXT.md)

Existing Plans

• ✅ free: $0, 100 credits
• ✅ starter: $89, 1,000 credits
• ✅ growth: $139, 2,000 credits
• ✅ scale: $229, 4,000 credits
• ✅ enterprise: $0, 10,000 credits

Recommendation

Use existing 'free' plan (100 credits) OR create 'free-trial' (2000 credits)

🧪 Testing Commands

Test Migration

docker exec igny8_backend python manage.py makemigrations --dry-run
docker exec igny8_backend python manage.py migrate --plan

Test Signup

# After migration, test at https://app.igny8.com/signup
# Should create account with credits seeded

Verify Database

docker exec igny8_backend python /app/check_current_state.py
# Should show payment_method fields in Account and Subscription

Test API Key Validation

# Suspend an account, try API key request - should return 403

Test Throttling

# Make many requests from same account - should get 429

Test Bank Transfer

curl -X POST http://localhost:8011/api/v1/billing/admin/confirm-bank-transfer/ \
  -H "Authorization: Bearer <admin_jwt>" \
  -H "Content-Type: application/json" \
  -d '{
    "account_id": 1,
    "external_payment_id": "BT-TEST-001",
    "amount": "89.00",
    "payer_name": "Test User"
