What are the best practices for using decorators in Django?

When using decorators in Django, it's important to keep them simple, reusable, and well-documented. Avoid complex logic inside decorators.

Can you give me an example of a simple decorator?

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

import time
from django.http import HttpResponse

def timing_decorator(view_func):
    def wrapper(*args, **kwargs):
        start_time = time.time()
        response = view_func(*args, **kwargs)
        end_time = time.time()
        print(f"Execution time: {end_time - start_time} seconds")
        return response
    return wrapper

How can I apply this decorator to a Django view?

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

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

Are there any performance considerations I should be aware of?

Yes, decorators can add overhead, especially if they perform complex operations. Always measure performance impacts when using them.
