What are advanced decorators in Django and how can I use them?

Advanced decorators in Django are functions that modify the behavior of views or other functions. They can be used for tasks like authentication, caching, and more.

Can you give me an example of a custom decorator?

Sure! Here's a simple example of a custom decorator that logs the execution time of a view:

import time
from django.http import HttpResponse

def timeit(view_func):
    def _wrapped_view(request, *args, **kwargs):
        start_time = time.time()
        response = view_func(request, *args, **kwargs)
        duration = time.time() - start_time
        print(f"Execution time: {duration} seconds")
        return response
    return _wrapped_view

@timeit
def my_view(request):
    return HttpResponse('Hello, world!')

How do I apply multiple decorators to a single view?

You can stack decorators by applying them one after the other. For example:

@decorator_one
@decorator_two
def my_view(request):
    return HttpResponse('Hello, world!')

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 help manage access and HTTP methods for your views.
