login_required on class django

@login_required is a decorator in Django that is used to restrict access to certain views or class-based views to only logged-in users. It ensures that only authenticated users can access the view by redirecting unauthenticated users to the login page.

Here is an explanation of the steps involved when using @login_required on a class-based view in Django:

1. Import the required modules: Before using @login_required, you need to import it from the django.contrib.auth.decorators module. You'll also need to import the necessary classes and modules related to your view.

2. Add the decorator to the view: To restrict access to a class-based view, you need to add the @login_required decorator above the class definition. This decorator ensures that only authenticated users can access the view.

3. Handle the redirect for unauthenticated users: By default, @login_required redirects unauthenticated users to the login page. Django handles this redirection automatically. You don't need to write any additional code for this.

4. Access the view: Once the @login_required decorator is applied to the class-based view, only logged-in users will be able to access the view. If an unauthenticated user tries to access the view, they will be redirected to the login page.

That's it! By using the @login_required decorator on a class-based view in Django, you can restrict access to only authenticated users, providing a secure way to protect sensitive information or functionality.
