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

Django view decorators are functions that modify the behavior of view functions. They are used to add functionality like authentication, caching, and more.

Can you give me an example of a common decorator?

Sure! A common decorator is @login_required, 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 a view function as an argument, and return a new function that adds your desired behavior.

Can you show me a code example of a custom decorator?

Absolutely! Here's a simple example:

from django.http import HttpResponse

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