What are decorators in Django and how do I use them?

Decorators in Django are a way to modify the behavior of a function or method. They are often used for tasks like authentication, permission checks, and caching.

Can you give me an example of a decorator in Django?

Sure! A common example is the @login_required decorator, which restricts access to a view to only authenticated users.

How do I create my own custom decorator?

To create a custom decorator, define a function that takes another function as an argument, and then return a new function that adds the desired behavior.

Can you show me a code snippet for a custom decorator?

Absolutely! Here's a simple example:

def my_custom_decorator(view_func):
    def wrapper(request, *args, **kwargs):
        # Add custom behavior here
        return view_func(request, *args, **kwargs)
    return wrapper
