What are the best practices for using decorators in Django?

When using decorators in Django, it's important to keep them simple, reusable, and well-documented. Avoid complex logic inside decorators.

Can you give an example of a simple decorator?

Sure! Here's a simple decorator that checks if a user is authenticated before allowing access to a view:

from django.http import HttpResponseForbidden

def user_is_authenticated(view_func):
    def _wrapped_view(request, *args, **kwargs):
        if request.user.is_authenticated:
            return view_func(request, *args, **kwargs)
        return HttpResponseForbidden()
    return _wrapped_view

How can I apply this decorator to a view?

You can apply the decorator by using the @ symbol above your view function like this:

@user_is_authenticated
def my_view(request):
    return HttpResponse('Hello, authenticated user!')

Are there any built-in decorators I should know about?

Yes! Django provides several built-in decorators like @login_required, @permission_required, and @require_http_methods that can simplify your code.
