How Django processes a request (URL → View → Template) - Quick Revision & Summary

Recall & Review

beginner

What is the first step Django takes when it receives a web request?

Django looks at the URL of the request and tries to match it with a pattern defined in the URL configuration (urls.py).

beginner

What role does a view play in Django's request processing?

A view is a function or class that takes the request and returns a response, often by processing data and selecting a template to render.

beginner

How does Django use templates in processing a request?

Templates are HTML files with placeholders. Django fills these placeholders with data from the view to create the final HTML sent to the browser.

beginner

What happens if Django cannot find a matching URL pattern for a request?

Django returns a 404 Not Found error page to the user, indicating the requested page does not exist.

Explain the flow of data from URL to template in Django.

The URL pattern matches the request and calls the view. The view processes data and passes it to the template. The template renders the data into HTML, which Django sends back as the response.

What file in Django contains the URL patterns that map URLs to views?

A settings.py

The urls.py file defines URL patterns that tell Django which view to call for each URL.
