What are advanced decorators for function views in Python?

Advanced decorators in Python are functions that modify the behavior of other functions or methods. They can be used in function views to add functionality like authentication, logging, or caching.

Can you give me an example of a decorator for authentication?

Sure! Here's a simple authentication decorator:

from functools import wraps

def login_required(f):
    @wraps(f)
    def decorated_function(*args, **kwargs):
        if not user_is_authenticated():
            return 'Unauthorized', 401
        return f(*args, **kwargs)
    return decorated_function

How would I apply this decorator to a function view?

You can apply the decorator by placing it above your function definition like this:

@login_required
def my_view():
    return 'This is a protected view!'

What other types of decorators can I use?

You can use decorators for logging, caching, rate limiting, and more. Each serves a different purpose to enhance your function views.
