  Benefits of DjangoArchitectureThe Django Framework is predicated on this design and it really communicates between these 3elements without having to put in writing complicated code. That’s why Django is gainingquality.This design in Django has numerous blessings like:1. Rapid Development: Django design that separates in different components makes iteasy for multiple developers to work on different aspects of the same applicationsimultaneously. That's additionally one among the options of Django.2. Loosely Coupled: Django has totally different elements that need one another at boundelements of the application, at each instant, that will increase the safety of the generalwebsite. Because the model file can currently solely save on our server instead of savingon the webpage.3. Ease of Modification:This can be a crucial fact of development as there area unit totallydifferent elements in Django design. If there's a modification in numerous elements, wetend not to modify it in alternative elements. This can be really one among the specialoptions of Django, as here it provides us a way with more ability of our web site thanalternative frameworks.4.

It’s used to runmanagement commands related to our project. We will use it to run the developmentserver, run tests, create migrations and much more.● __init__.py: this empty file tells Python that this folder is a Python package.● settings.py: this file contains all the project’s configuration. We will refer to this file allthe time!● urls.py: this file is responsible for mapping the routes and paths in our project. Forexample, if you want to show something in the URL /about/, you have to map it herefirst.

  ● wsgi.py: thisfile is a simple gateway interface used for deployment.Now everything is st up and we can run the server using below commandpython manage.py runserverNow open the URL in a Web browser: http://127.0.0.1:8000 and you should see the successpage, which means the server is running correctly.Creating Django AppsDjango project contains many apps within it. An app can't run without a project. You can createapp by the following commanddjango-admin startapp articlesThis will give us the following directory structure:myproject/|-- myproject/| |-- articles/ <-- our new django app!| | |-- migrations/| | | +-- __init__.py| | |-- __init__.py| | |-- admin.py| | |-- apps.py| | |-- models.py| | |-- tests.py| | +-- views.py| |-- myproject/| | |-- __init__.py| | |-- settings.py| | |-- urls.py| | |-- wsgi.py| +-- manage.py+-- venv

  So, let’s firstexplore what each file does:● migrations/: here Django stores some files to keep track of the changes you create inthe models.py file, so to keep the database and the models.py synchronized.● admin.py: this is a configuration file for a built-in Django app called Django Admin.● apps.py: this is a configuration file of the app itself.● models.py: here is where we define the entities of our Web application. The models aretranslated automatically by Django into database tables.● tests.py: this file is used to write unit tests for the app.● views.py: this is the file where we handle the request/response cycle of our Webapplication.Now that we created our first app, let’s configure our project to use it. Open settings.py file andfind installed_apps block.settings.pyINSTALLED_APPS = ['django.contrib.admin','django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions','django.contrib.messages','Django.contrib.staticfiles',‘articles’]Here we have added ‘articles’ in the installed apps section. Now the app is ready to run with theDjango project.Configuring DatabaseBy default Django project comes with sqlite3 database but you can customize it to use MySQLor Postgresql as per the requirements.settings.py

  DATABASES = {'default':{'ENGINE': 'django.db.backends.postgresql_psycopg2','NAME': 'blog','USER': 'postgres','PASSWORD': '**********','HOST': 'localhost','PORT': 5432,}}Now your project is connected with Postgres database and ready to run.ConclusionIn this blog we have learned how the MVT pattern works and the structure of Djangoapplication along with the database configuration.
