# Django rules

- Use `python manage.py startapp` to create a new application in the project
- Save models in `models.py` and register them in `admin.py` to use the admin interface
- Use Django's ORM instead of raw SQL queries
- Use `select_related` and `prefetch_related` to avoid N+1 query problems:

```python
# Good mode
users = User.objects.select_related('profile')
posts = Post.objects.prefetch_related('tags')

• Use Django forms for validation:

class UserForm(forms.ModelForm):
    class Meta:
        model = User
        fields = ['username', 'email']

• Create custom model managers for common queries:

class ActiveUserManager(models.Manager):
    def get_queryset(self):
        return super().get_queryset().filter(is_active=True)

• Use Django's built-in authentication system
• Store settings in environment variables and access them via settings.py ```
