3. Why is Django so famous?

Django is the best framework for Python, there are many reasons behind it.
First, it is the fastest, second is the number of components that it has and third is it’s scalability.
Django follows the popular MVC (Model-View-Controller) pattern as is used by most web frameworks.
But there is a slight twist in MVC pattern of Django.
Let’s see it.
In the Django Framework, instead of MVC, this pattern is called as MVT.

4. What is Django MVT Pattern?

MVT stands for Model View Template.
The difference between MVC and MVT is that in the MVT pattern, the job of the controller is handled by Django itself and this is the advantage of the Django web framework.
Let’s understand all the three components of MVT pattern.
Model – Model is the logical represntation of data model.
Each entity in the model represents the field of the database.
View – The screen that we see on a web browser is called a view.
A view contains the code of HTML, CSS and Client-side such as Java Script.
Template – This is an important part of the MVC pattern. It works like a middleman and connects the View and Model components of MVT pattern.

5. How to install Django framework for Python?

Let us now see how to install Django.
First you need to install the latest version of Python. If you don’t know how to install Python – Click Here
Django is an open source and the latest version of Python is recommended with it.
You can install the specific version of Django framework for Python using below command –
You can use windows cmd prompt to run this command.
pip install Django==<version  of Django>
pip install Django==3.0.7

After the installation, you can know about the Django version with the command given below.

django-admin –version
Versions of Django Web Framework

The following versions of Django are to come in the future.
 Version            Release Date

 4.0       December 2021
 4.1        August 2022
 4.2 LTS        April 2023

6. How to create a Project using Django admin?

Once the Django is installed, we will create a basic project using the Django admin.
To create a new project use the following command –
django-admin startproject MyFirstProject

Once the command is successful, a project will have been created at your folder location.


Now we need an IDE to work on this project, we will use visual studio code to do this. You can use any editor if you want, it depends on your comfort and choice.

Open this project in Visual Studio Code and open terminal.
To open terminal in Visual Studio Code. Right Click on and select open in terminal
and now type below command.
python runserver
Open the URL below in the browser after a successful execution.
And with this, we have successfully run our first Django based application. I really like this.
So in this way we made a project based on Django and it was successfully run.

Now we will see how new apps can be added to a Django based project.

Use below command to add a new app to the Django based Python project.
python startapp myenewapp
Now you will see that a new app has been added to your project, just like you can add any number of apps to your project.
Now we will work on this new added app.
To run any app, we need a URL, to apply URL to the app, first of all we will add a file to our app.
Right click on your app name and create a new file, type in file name field. So in this way you have added a file named to your app.
First,you need to add the URL of your new app in file of your project.
Below is the content of which is in main project folder.
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
Now all you have to do is to copy the content of the file which is in the root of your project, and paste it in this new which you added to your app.
Below is the content of which is in mynewapp
from django.urls import path
from . import views
urlpatterns = [
    path('', views.home,name='welcome page')
path contains 3 parameters –
1. Route – This is a required parameter which defines the route or url for your app.
If route parameter is empty then your app will run on default project url i.e. like a start page.
If you want to run your app with a different url then type some value in route parameter.
For eg – path(‘dashboard’, views.dashboard,name=’dashboardpage’)
Above path will run with this url – <Project URL/dashboard>
path(‘login’, views.account,name=’login page’)
Above path will run with this url – <Project URL/login>
2. view – This is another required parameter.
3. name – This is an optional parameter.
Now open file from your app and paste this code –
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def home(request):
    return HttpResponse("This is first Django based app")
Now you can run your project by using below command, or wait till the IDE detect the change and compile the code automatically.
python runserver
After Code execution, open the browser and enter the URL, as you did earlier.
And hopefully you will have seen your new content. If so, then you have successfully run it by adding a new app in Django.

7. How to add HTML page in Python with Django framework?

So far it is fine, but if we have to work on a pure HTML page and render it on the browser then what will be the approach in the Django framework.
To do this first create a folder in you project and name it templates this folder should be parallel to your app folder. Now you can add HTML file within this templates folder. I have create home.html with below content.
        <title>Welcome to Django Tutorial</title>
        <h1>Welcome to Django Tutorial</h1>
        <p>This is a Django tutorial about environment setup</p>
Now here is a little twist which is something to understand. To render this HTML page we need to do little changes in and
Step 1 – Open file and change this as per below code
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def home(request):
    return render(request,'home.html')
Step 2 – Open file and within Templates array modify the DIRS array to this –
 'DIRS': [os.path.join(BASE_DIR, 'templates')],
Now, run your application and you will see the output as per your HTML file.
