What are the differences between context managers and decorators in Django?

Context managers and decorators serve different purposes in Django. Context managers are used for resource management, ensuring that resources are properly acquired and released, like opening and closing files. Decorators, on the other hand, are used to modify or enhance functions or methods, often for purposes like authentication or logging.

Can you give me an example of a context manager in Django?

Sure! A common example of a context manager in Django is using the transaction.atomic() context manager, which ensures that a block of code is executed within a database transaction. If an error occurs, the transaction is rolled back.

And what about a decorator? Can you show me one?

Absolutely! A simple example of a decorator in Django is the @login_required decorator. It restricts access to a view, ensuring that only authenticated users can access it.

How do I choose between using a context manager or a decorator?

Choose a context manager when you need to manage resources and ensure proper cleanup. Use a decorator when you want to modify the behavior of a function or method without changing its code.
