Let’s understand the MVC Pattern

Model View Controller
MVC is a software design pattern for developing web applications.

MVC-MVT Pattern

Django MVC-MVT Pattern
➢ MVC is slightly different from MVT as Django itself takes care of the Controller part.
➢ It leaves the template which is a HTML file mixed with Django Template Language (DTL).
Model
View
Template

Architecture
The developer provides the Model, the view and the template then just maps it to a URL
and Django does the magic to serve it to the user.

Demo
Now, let’s create your first basic Web App

Create a Project
$ django-admin startproject myproject
Open the terminal and navigate to the folder where the project is to be created.
Myproject/
manage.py
myproject/
__init__.py
settings.py
urls.py
wsgi.py
This will create a "myproject" folder with the following structure:
