The views document is somewhat confusingly named, but can be thought of as managing traffic. It is the view’s job to get the right data for the right route delivered in the right form. Views handle the data we deliver to the user to view.

Question 6

What is the MTV vs MVC framework

Answer 6

Django:
Model - Builds database tables and handles logic that relies on data.
Template - HTML page that gets served to the client
View - Deals with aggregating data that should be returned as part of a template.

MVC:
Model - Builds database tables and may or may not contain some logic
View - HTML page that gets served to the client
Controller - May contain some logic. Receives incoming requests and sends collected data back as part of a template.
