How do I use authentication decorators in Django?

In Django, authentication decorators like @login_required are used to restrict access to views. You can apply them to your view functions to ensure that only authenticated users can access them.

Can you show me an example of using @login_required?

Sure! Here's a simple example:

from django.contrib.auth.decorators import login_required

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

This will redirect unauthenticated users to the login page.

What happens if a user is not logged in?

If a user is not logged in, they will be redirected to the login page specified in your Django settings. You can customize the redirect URL if needed.

Are there other decorators for permissions?

Yes, Django also provides decorators like @permission_required and @user_passes_test for more granular control over access based on user permissions or custom conditions.
