Although both procedures are used to retrieve related fields from a model, their functionality differs slightly. In simple terms, select related employs a foreign key relationship, which means it uses join on the query itself, whereas prefetch related does a separate lookup and joining on the Python side.
This ORM (Object Relational Mapper) allows us to deal with databases in a more pythonic approach, such as avoiding writing raw queries and retrieving, saving, deleting, and performing other database activities without ever writing a SQL query. It functions as a layer of abstraction between the models and the database.
A view function, or simply "view," is a Python function that receives a web request and provides a web response. This response could be the HTML content of a web page, a redirect, a 404 error, an XML document, or a picture, among other things.
Django developers and Python developers (with Django expertise) are in high demand. Companies prefer candidates who have had hands-on Django training and are proficient in Python.
