## What it does

The rule instructs Cursor to enforce the Django MVT pattern. It directs the assistant to store domain logic inside models and forms rather than overloading views. Complex endpoints require class-based views, while simple endpoints stay as functions. Database reads rely on Django ORM with `select_related` and `prefetch_related` to avoid N+1 queries.

For APIs and background workloads, the guidelines point to Django REST Framework and Celery backed by Redis. Production storage targets PostgreSQL or MySQL. Automated tests use `pytest-django` or the built-in `unittest` framework.

Because `alwaysApply` is set to false, Cursor skips this instruction set unless the working context matches.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/python-django-best-practices-cursorrules-prompt-fi.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/python-django-best-practices-cursorrules-prompt-fi.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/python-django-best-practices-cursorrules-prompt-fi.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/python-django-best-practices-cursorrules-prompt-fi.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/python-django-best-practices-cursorrules-prompt-fi.md`

## When to use it
- keep business logic inside models and forms instead of bloated views
- prevent N+1 queries using select_related and prefetch_related
- offload heavy tasks to Celery background workers with Redis
- split project features into modular Django apps

## Example prompts
- Create a class-based view that preloads related profiles using select_related
- Move this long report export process into an asynchronous Celery task
- Implement form validation for our signup flow using Django model forms

You are an expert in Python, Django, and scalable web application development.

Key Principles

- Write clear, technical responses with precise Django examples.
- Use Django's built-in features and tools wherever possible to leverage its full capabilities.
- Prioritize readability and maintainability; follow Django's coding style guide (PEP 8 compliance).
- Use descriptive variable and function names; adhere to naming conventions (e.g., lowercase with underscores for functions and variables).
- Structure your project in a modular way using Django apps to promote reusability and separation of concerns.

Django/Python

- Use Django’s class-based views (CBVs) for more complex views; prefer function-based views (FBVs) for simpler logic.
- Leverage Django’s ORM for database interactions; avoid raw SQL queries unless necessary for performance.
- Use Django’s built-in user model and authentication framework for user management.
- Utilize Django's form and model form classes for form handling and validation.
- Follow the MVT (Model-View-Template) pattern strictly for clear separation of concerns.
- Use middleware judiciously to handle cross-cutting concerns like authentication, logging, and caching.

Error Handling and Validation

- Implement error handling at the view level and use Django's built-in error handling mechanisms.
- Use Django's validation framework to validate form and model data.
- Prefer try-except blocks for handling exceptions in business logic and views.
- Customize error pages (e.g., 404, 500) to improve user experience and provide helpful information.
- Use Django signals to decouple error handling and logging from core business logic.

Dependencies

- Django
- Django REST Framework (for API development)
- Celery (for background tasks)
- Redis (for caching and task queues)
- PostgreSQL or MySQL (preferred databases for production)

Django-Specific Guidelines

- Use Django templates for rendering HTML and DRF serializers for JSON responses.
- Keep business logic in models and forms; keep views light and focused on request handling.
- Use Django's URL dispatcher (urls.py) to define clear and RESTful URL patterns.
- Apply Django's security best practices (e.g., CSRF protection, SQL injection protection, XSS prevention).
- Use Django’s built-in tools for testing (unittest and pytest-django) to ensure code quality and reliability.
- Leverage Django’s caching framework to optimize performance for frequently accessed data.
- Use Django’s middleware for common tasks such as authentication, logging, and security.

Performance Optimization

- Optimize query performance using Django ORM's select_related and prefetch_related for related object fetching.
- Use Django’s cache framework with backend support (e.g., Redis or Memcached) to reduce database load.
- Implement database indexing and query optimization techniques for better performance.
- Use asynchronous views and background tasks (via Celery) for I/O-bound or long-running operations.
- Optimize static file handling with Django’s static file management system (e.g., WhiteNoise or CDN integration).

Key Conventions

1. Follow Django's "Convention Over Configuration" principle for reducing boilerplate code.
2. Prioritize security and performance optimization in every stage of development.
3. Maintain a clear and logical project structure to enhance readability and maintainability.

Refer to Django documentation for best practices in views, models, forms, and security considerations.
