Django is an open-source web development framework based on the Python language, allowing Python developers to create database-driven websites.

Ques 3. What are the advantages of Django?

Most developers prefer Django due to its dominance in the market, as it shows high computational and statistical capabilities. The following are some of the advantages of Django:

  • Django follows Python’s ‘batteries included’ trait. Python is generally referred to as ‘batteries included’ because it has a unified standard library, helping developers use readymade packages to add features to a web project. 
  • Most of the packages in Python’s standard library are open-source. With these packages, you can even implement authentication, admin interfacing, session management, and other advanced functionalities. 
  • Python and Django are core technologies in IT giants, the Internet of Things (IoT), and blue chip companies. Therefore, learning it would help you establish a lucrative career. 


  • Security is yet another advantage of using the Django framework. Applications developed on Django are protected against SQL injection, clickjacking, XSS and CSRF attacks, etc.
  • The built-in template language of Django promotes the process of building applications. 
  • Django enables developers to create applications and configure frameworks on the go. Also, it offers support for external libraries and packages. Django focuses on explicit programming, allowing the developers to create applications that require frequent changes.
  • It helps in faster development and is thus used by most companies. If the configuration is correct, then you can use Django for optimizing web applications.
  • Django has a REST framework, a python library, that helps develop APIs for many applications. Using these APIs, you can add advanced functionalities to your applications.
  • Django comes with ML capabilities and libraries such as PyTorch, NumPy, etc.

Ques 7. Describe the Django architecture.

Django follows the Model-View-Template(MVT) architecture based on a popular Model-View-Controller(MVC) architectural pattern, which is followed by popular web-frameworks like Ruby on Rails, Laravel etc.

Django’s Model-View-Template architecture divides the complete application into three major logical components:

  1. Model 
  2. View
  3. Template

All these three components are responsible for handling the different aspects of the web application.

ModelThe models handle the database schema for the web applications. It maintains and represents the complete application data into the database. The default relational database used by the model is SQLite which is generally used in development, but in production we can use the MySQL and Postgres.

ViewThe view component manages all the logic of the application that we want to render on the user’s browser. In Django, the view acts as a bridge between the models and the templates. In the views, we can fetch the data from the models and render it on the template.

TemplateThe template component is the collection of static parts of the application such as the HTML, CSS, JavaScript, and Image files. The view uses the template as the base on which the data should be presented, because at the end, the web-application uses the static files to represent the content on the user browser.

Ques 8. What is the project directory structure in Django?

The following is the project directory structure in Django:

Ques 9. What are the components of the Django architecture?

The architecture of Django consists of the following components:

  • Models: It specifies the database schema and the data structure
  • Views: It controls what a user will see, the view used to retrieve the data from appropriate models, implement calculation on the data, and pass it to the desired template
  • Templates: It specifies how the user sees it. It describes how the data received from the views should be formatted to display on a page
  • Controller: The Django framework and URL parsing

Ques 10. What does it mean to say that Django is monolithic?

Django is based on the MVT architecture, and since Django is the controller of the architecture, it has defined some rules that all developers need to follow to execute appropriate files at the right time.

In Django, you get great customizability with implementation. But you are not allowed to make changes to the file names, the predefined lists, and variable names. You have to create the new ones, but you can’t make changes to the predefined variables.

The monolithic behavior helps the developers to understand the project easily. Even if the company changes, the project layout will remain the same. Therefore, developers take less time to understand the code, increasing productivity.

Ques 14. What is the file in Django?

Whenever you create a project, the file is automatically created. This is a command-line utility, helping you to interact with your Django project. It performs the same work as Django-admin and sets the DJANGO_SETTINGS_MODULE environment variable to point to your project’s settings. It is better if you use instead of Django-admin if you are working on a single project.

Ques 15. What is the response cycle in Django?

Whenever a user requests a web page, Django will create an HttpRequest object containing the important metadata about that request. After that, Django will load a particular view, passing the HttpRequest as its first argument to the view function. Each view then returns an HttpResponse object.

The following are the steps that take place when a request is received by Django:

  • Firstly, the file, which contains various middleware classes, is loaded
  • All the middleware classes get executed in the same order in which they are mentioned
  • Now, the request will be moved to the URL Router. The URL Router gets the URL path from the request and later tries to map with the given URL paths within the
  • After mapping, it calls the equivalent view function, from where the corresponding response is generated.
  • The response now passes through the response middleware and is sent back to the client/browser

The following are the exception classes available in Django:




Raised when we try to use models before the app loading process.

Raised if the requested field does not exist.


A query will raise this exception if only one object is expected, but multiple objects are returned.


Raised when a suspicious operation has been performed by the user.


Raised when a user does not have an appropriate permission to perform a specified action.


Raised by django.urls if the requested view does not exist.


Raised if a middleware is not used in the server configuration.


Raised if Django is somehow improperly configured.


Raised if there is a problem with a model field.
