## 2. Development Workflow
1. **Plan Your Project**
- Define models, views, and URL structure
- Create a list of features and prioritize them
2. **Set Up the Project**
- Create a virtual environment
- Install Django and other dependencies
- Start a new Django project
- Configure settings.py (database, static files, etc.)
3. **Create Apps**
- Use `python manage.py startapp` for each major feature
- Move apps into the `apps/` directory for better organization
4. **Define Models**
- Design your data schema in `models.py`
- Create migrations: `python manage.py makemigrations`
- Apply migrations: `python manage.py migrate`
5. **Create Views and Templates**
- Implement view logic in `views.py`
- Create corresponding HTML templates
6. **Configure URLs**
- Set up URL patterns in `urls.py` (both project and app level)
7. **Implement Forms**
- Create forms for data input and processing
8. **Add Static Files**
- Organize CSS, JavaScript, and images in static directories
9. **Set Up Admin Interface**
- Customize `admin.py` for each app
10. **Write Tests**
- Create unit tests for models, views, and forms
- Run tests frequently: `python manage.py test`
11. **Implement Authentication and Authorization**
- Set up user registration, login, and permissions
12. **Continuous Development and Iteration**
- Regularly commit changes to version control
- Refactor code as needed
- Add new features incrementally
13. **Documentation**
- Maintain a README.md with project setup instructions
- Document complex parts of your code
14. **Deployment Preparation**
- Set up production settings
- Collect static files: `python manage.py collectstatic`
- Configure your web server (e.g., Gunicorn, Nginx)
## Best Practices
- Follow PEP 8 style guide for Python code
- Use meaningful names for variables, functions, and classes
- Keep views thin, move business logic to models or separate service classes
- Use class-based views for reusable, DRY code
- Leverage Django's built-in features (forms, authentication, admin) when possible
- Use environment variables for sensitive information
- Regularly update dependencies and Django version
