After creating models, we know, we have to run ‘makemigrations’ command in the console so that our database is prepared with all the columns in it which we defined in our models.py file inside an app. Suppose you created a registration form and you displayed it in your website. Now if someone registers himself/herself and then wishes to see his/her profile or even if admin wishes to see the data of his customer in the website (not in database) then it means we have to plan something so that the data submitted by the customer which is stored in our database could somehow be fetched and presented in the webpage.
Thats what we are going to do here. I will simply fetch the data from database without focusing on its presentation in the webpage.
