Django Interview Questions And Answers

1. Difference Between Flask and Django:

Ans.

• Flask:
  • Micro-framework for web development.
  • Offers flexibility and simplicity.
  • Minimalistic and requires manual configuration.
  • Suitable for small to medium-sized projects.
• Django:
  • Full-stack web framework.
  • Follows the “batteries-included” philosophy, providing many built-in features.
  • Follows the MVC (Model-View-Controller) architectural pattern.
  • Suitable for large and complex projects.

2.Django:

Ans.
Django is a high-level, Python web framework that encourages rapid development and clean, pragmatic design. It follows the Model-View-Controller (MVC) architectural pattern, known as Model-View-Template (MVT) in Django’s terminology.

3.Companies Using Django:

Ans.

• Instagram
• Pinterest
• Dropbox
• Spotify
• Mozilla
• NASA
• The Washington Times
• Eventbrite

4.Features of Django:

Ans.

• Object-Relational Mapping (ORM)
• Admin Interface
• URL Routing
• Template Engine
• Form Handling
• Authentication and Authorization
• Middleware Support
• Built-in Testing Framework
• Internationalization and Localization

5.Checking Django Version:

Ans.
You can check the version of Django installed on your system by running the following command in the terminal or command prompt:

   python -m django --version

6. Advantages of Using Django:

• Rapid Development
• DRY (Don’t Repeat Yourself) Principle
• Batteries-Included
• ORM for Database Interaction
• Built-in Admin Interface
• Secure by Default
• Scalability
• Community and Documentation

7.Django Architecture:

Ans.
Django follows the Model-View-Template (MVT) architecture, which is a slight variation of the traditional Model-View-Controller (MVC) pattern.

• Model: Represents the data structure and business logic of the application.
• View: Handles the presentation logic and user interface.
• Template: Manages the rendering of the HTML and dynamic content.

8.Django Project Directory Structure:

Ans.
Django projects follow a specific directory structure. A typical Django project consists of the following main components:

• project_name/: The main project directory.
• manage.py: A command-line utility for interacting with the project.
• app_name/: Individual applications within the project.
• settings.py: Configuration settings for the project.
• urls.py: URL patterns and routing for the project.
• wsgi.py: Web Server Gateway Interface for deployment.
• views.py: Contains views, which handle user requests and return responses.
• models.py: Defines data models and database schema.
• admin.py: Configuration for the built-in admin interface.
• templates/: Directory for HTML templates.
• static/: Directory for static files (CSS, JavaScript, images).

9.Ans. Django ORM is a feature of the Django web framework that simplifies database interactions using object-oriented programming. It allows developers to define models using Python classes, automatically generates the database schema, and provides a Pythonic QuerySet API for data retrieval, insertion, updating, and deletion. Django ORM abstracts away SQL complexities, supporting various database backends. It simplifies transactions, aggregations, and other common database operations.

10. Ans. Django Rest Framework (DRF) is a powerful and flexible toolkit for building Web APIs in Django applications. It extends Django to handle common patterns for RESTful APIs, providing a convenient way to serialize data, handle authentication, and define views for API endpoints. DRF simplifies the process of building robust and scalable APIs in Django projects by offering features such as serialization, authentication, permissions, viewsets, and routers. It is widely used for developing RESTful APIs in conjunction with Django, allowing developers to create web services that can be consumed by various client applications.
