Creation of new django app

1. What is a django application? 

So far, we've only seen one procedure for creating a Django project. Now, in this section, we will create an application inside the created project. You may be wondering, what is the difference between a django project and a django application? The difference between the two is that a project is a collection of configuration files and applications, while the application is a web service that is added to your django project.

2. Creation of an application called myapp 

 A website project is usually made up of a set of applications. For this purpose we will create a new application named myapp within our mysite project. To do this, go to the cmd command prompt using the directory of your mysite project and type the command:
python manage.py startapp myapp

3. Configuration of the myapp application

Now for the new application to be operational, it will be necessary to make a few configurations beforehand:

1. Creation of the view for the application myapp  (myapp/views.py):


# Importing necessary classes and modules
from django.shortcuts import render                     
from django.http import HttpResponse  

# Create the method that generates the views           
def hello(request): 
    # displaying message by using the HttpResponse class      
    return HttpResponse('Welcome to myapp !') 

2. The second step is to add the view path in the urls.py file(mysite/urls.py)

from django.contrib import admin
from django.urls import path
from myapp import views

urlpatterns = [
     path ('admin /', admin.site.urls),
     path ('hello /', views.hello),
]
3. Now start your server using the command:
python manage.py runserver
and then type the url address:  http://127.0.0.1:8000/hello/  in your browser to see the home page of your new application:
