# CCE Django Plugin

Professional Django backend development suite for Claude Code, featuring specialized agents for models, APIs, and ORM optimization.

## Overview

The **cce-django** plugin provides expert Django development capabilities through three specialized agents that understand Django best practices, project-specific patterns, and current framework features. Whether you're building REST APIs with Django REST Framework, implementing GraphQL endpoints, or optimizing complex database queries, this plugin delivers intelligent, project-aware solutions.

## Features

### Comprehensive Django Coverage

- **Backend Development**: Models, views, services, middleware, signals, management commands
- **API Development**: Django REST Framework (DRF) viewsets, serializers, GraphQL with Graphene
- **ORM Optimization**: Query optimization, database design, migrations, performance tuning
- **Security & Testing**: Django security best practices, comprehensive test patterns
- **Async Support**: Django 4.1+ async views, Channels for WebSockets, Celery integration

### Intelligent Project Integration

All agents analyze your existing codebase before implementing features:
- Detect project-specific naming conventions and architecture patterns
- Integrate seamlessly with existing models, serializers, and views
- Respect current authentication methods and permission classes
- Follow established coding standards and Django app structure

### Always Current

Agents fetch the latest Django and DRF documentation before implementing features, ensuring you use current best practices and syntax for your Django version.

## Installation

### From Marketplace (Recommended)

```bash
# Add the CCE marketplace
/plugin marketplace add https://github.com/nodnarbnitram/claude-code-extensions

# Install the Django plugin
/plugin install cce-django@cce-marketplace
```

### From Local Source

```bash
# Clone the repository
git clone https://github.com/nodnarbnitram/claude-code-extensions.git

# Add as local marketplace
/plugin marketplace add /path/to/claude-code-extensions

# Install the plugin
/plugin install cce-django@cce-marketplace
```

## Usage

### Automatic Agent Delegation

When you request Django-related tasks, Claude Code automatically delegates to the appropriate specialized agent:

```bash
# Automatically uses django-backend-expert
> Create a Django model for blog posts with categories and tags

# Automatically uses django-api-developer
> Build a REST API for the blog with DRF serializers and viewsets

# Automatically uses django-orm-expert
> Optimize the blog post listing query to prevent N+1 issues
```

### Manual Agent Invocation

You can explicitly invoke agents when needed:

```bash
# Use the backend expert
> @django-backend-expert Create a custom User model with email authentication

# Use the API developer
> @django-api-developer Add GraphQL mutations for creating and updating posts

# Use the ORM expert
> @django-orm-expert Add database indexes for the most frequent queries
```

### Example Workflows

#### Building a Complete Feature

```bash
# 1. Backend expert creates models
> Create models for an e-commerce product catalog with categories and inventory

# 2. API developer builds endpoints
> Create a REST API for the product catalog with filtering and pagination

# 3. ORM expert optimizes performance
> Analyze and optimize the product listing queries for 100k+ products
```

#### Migrating from Function-Based to Class-Based Views

```bash
> @django-backend-expert Review the views in myapp/views.py and convert
  function-based views to class-based views following Django best practices
```

#### Adding Advanced Features

```bash
# GraphQL with DataLoader optimization
> @django-api-developer Add a GraphQL API with DataLoader to prevent N+1 queries

# Multi-tenant middleware
> @django-backend-expert Implement tenant isolation middleware using subdomains

# Complex analytics queries
> @django-orm-expert Build an analytics dashboard query that aggregates
  sales by category, month, and region
```

## Agent Coordination

Agents return structured reports that enable seamless coordination:

## Best Practices

### 1. Let Agents Analyze First

Agents examine your existing codebase before implementing features:
- They detect your project structure and conventions
- They match your naming patterns and code style
- They integrate with existing authentication and permissions

### 2. Leverage Latest Documentation

All agents fetch current Django/DRF documentation to ensure:
- You use the latest features for your Django version
- Deprecated patterns are avoided
- Security best practices are followed

### 3. Progressive Enhancement

Build features incrementally:
1. **Backend Expert**: Create models and business logic
2. **API Developer**: Add API endpoints
3. **ORM Expert**: Optimize performance as needed

### 4. Request Structured Output

Ask for structured reports when coordinating complex features:
```bash
> @django-backend-expert Create the order management models and
  return a structured report of components and integration points
```

## Plugin Commands

This plugin uses namespaced commands:

### In Plugin Mode
```bash
# Commands are namespaced with /cce-django:
# (Currently no commands - agents handle all functionality)
```

### In Standalone Mode
```bash
# Commands use unprefixed names
# (Currently no commands - agents handle all functionality)
```

## Troubleshooting

### Agent Not Activating

If agents don't activate automatically:
1. Check that the plugin is installed: `/plugin list`
2. Verify agents are loaded: `/agents` (should show django agents)
3. Use explicit invocation: `@django-backend-expert <task>`

### Documentation Fetch Issues

If agents can't fetch latest docs:
- Ensure you have internet connectivity
- Check if context7 MCP is configured (optional but recommended)
- Agents will fall back to built-in knowledge if fetch fails

### Performance Issues

For large Django projects:
- Use ORM expert for query optimization early
- Request profiling before implementing optimizations
- Ask for database index recommendations
