Mastering Django Web Development (Video 6)

This video tutorial covers the concept of middleware in Django, explaining its role in the request-response cycle. It discusses built-in middleware examples like sessions and CSRF protection, and how middleware can help avoid code repetition. The video also details the five middleware hooks: process request, process view, process template response, process response, and process exception, explaining their functions and use cases. Finally, it highlights the importance of the order of middleware execution, noting that middleware is processed in reverse order after the view function is called.

What is the primary role of middleware in a Django application?

• To render HTML templates

• To hook into the request-response cycle

• To manage user authentication

• To handle database migrations

Which of the following is an example of built-in Django middleware?

• Template rendering

• Session management

• URL routing

• Database connection

What does the 'process_request' hook in middleware do?

• It handles exceptions raised by the view

• It modifies the response before sending it to the client

• It is called after the view function is executed

• It processes each request before the view is determined

When is the 'process_exception' hook triggered in middleware?

• When a request is received

• When a template is rendered

• When a view function raises an exception

• When a response is about to be sent

How is middleware processed after the view function is called?

• In the same order as before the view

• In reverse order

• Randomly

• Only the first middleware is processed
