What are custom decorators in Django?

Custom decorators in Django are functions that modify the behavior of views or other functions. They allow you to add functionality like authentication, logging, or caching.

Can you give me an example of a custom decorator?

Sure! Here's a simple example:

from functools import wraps
from django.http import HttpResponseForbidden

def admin_required(view_func):
    @wraps(view_func)
    def _wrapped_view(request, *args, **kwargs):
        if not request.user.is_admin:
            return HttpResponseForbidden()
        return view_func(request, *args, **kwargs)
    return _wrapped_view

How do I apply this decorator to a view?

You can apply the decorator by using the @ symbol above your view function. For example:

@admin_required
def my_view(request):
    # Your view logic here

Are there any built-in decorators in Django?

Yes, Django provides several built-in decorators like @login_required, @permission_required, and @require_http_methods that you can use to manage access and HTTP methods.
