Django Web App - Development Plan

Overview

Building a production-ready Django app with user authentication, Stripe payments, wallet system, and n8n workflow integration.

Architecture

• users app: Custom user model, authentication
• wallet app: Wallet transactions, Stripe integration
• workflows app: n8n workflow triggering, usage tracking

Todo Items

High Priority - Core Setup

• Set up Django project structure with apps (users, wallet, workflows)
• Create custom User model with email authentication
• Create WalletTransaction model for wallet operations
• Create WorkflowUsage model for tracking n8n workflow usage
• Implement user authentication endpoints (signup, login)
• Create Stripe Checkout integration for wallet top-up
• Implement Stripe webhook handler for payment confirmation
• Create API endpoint for triggering n8n workflows
• Implement wallet balance checking and deduction logic

Medium Priority - Configuration & Admin

• Set up Django settings modularization (base, dev, prod)
• Set up Django Admin for monitoring users, balances, and logs
• Add authentication middleware and rate limiting
• Create requirements.txt and environment configuration

Low Priority - Deployment & Testing

• Add deployment configuration for Heroku/Render
• Write basic tests for critical functionality

Key Features

1. Authentication: Email-based signup/login
2. Wallet System: Stripe integration for top-ups, balance tracking
3. Workflow Integration: Secure n8n webhook triggering with fee deduction
4. Admin Interface: Monitor users, transactions, and usage
5. Security: Rate limiting, authentication middleware

Models Overview

• User: Custom user with email auth, wallet balance
• WalletTransaction: Track deposits, withdrawals, fees
• WorkflowUsage: Log workflow triggers and associated costs

Review Section

✅ Implementation Complete

All planned features have been successfully implemented:

🏗️ Core Architecture

• Clean Django project structure with 3 focused apps: users, wallet, workflows
• Modular settings (base, development, production) for different environments
• UUID primary keys for enhanced security and scalability
• Custom User model with email-based authentication

🔐 Authentication & Security

• JWT token-based authentication with DRF integration
• Email/password signup and login endpoints
• Rate limiting (10 requests/minute) for workflow triggers
• CSRF protection and secure headers for production
• Environment-based configuration with python-decouple

💰 Payment & Wallet System

• Stripe Checkout integration for seamless wallet top-ups
• Webhook handler for payment confirmation with signature verification
• Transaction logging for all wallet operations (deposits, withdrawals, fees)
• Balance validation before workflow execution
• Atomic transactions to prevent race conditions

🔄 Workflow Integration

• Secure n8n webhook triggering with authentication
• Automatic fee deduction ($0.10 configurable) per workflow
• Usage tracking with request/response logging
• Error handling with detailed logging for failed workflows
• Database transactions ensuring data consistency

🛠️ Admin & Monitoring

• Django Admin interface with custom configurations
• User management with wallet balance visibility
• Transaction monitoring with filtering and search
• Workflow usage tracking with collapsible JSON data
• Comprehensive logging for all operations

📦 Production Ready

• Heroku/Render deployment configuration (Procfile, runtime.txt)
• PostgreSQL production database support
• Static file serving with WhiteNoise
• Environment variable management with .env.example
• Comprehensive README with setup instructions

🧪 Testing

• Unit tests for User model and authentication
• API endpoint testing setup
• Wallet operations testing (balance checks, deductions)
• All tests passing ✅
