In today’s competitive job market, mastering Django—the high-level Python web framework—is a great way to stand out in backend and full-stack developer interviews. Django helps developers build secure, scalable, and maintainable web applications faster. If you’re preparing for an interview, this guide will walk you through the top Django interview questions for 2025, complete with clear and concise answers to help you build confidence.

Whether you're a fresher or an experienced developer, brushing up on these Django interview questions will give you an edge in your next tech round.

1. What is Django and why is it used?
   Django is a high-level Python web framework that enables rapid development of secure and maintainable websites. It follows the model-template-view (MTV) architecture and is known for its simplicity, flexibility, and robustness.

2. What are the key features of Django?
   Fast development

Secure and scalable

ORM (Object-Relational Mapping)

Admin interface

Middleware support

Template engine

Built-in authentication and authorization

1. Explain the Django MTV architecture. Model: Handles the database structure.

Template: Manages how data is presented to users (HTML).

View: Controls the logic and data flow between the model and template.

1. How does Django handle database migrations?
   Django uses the makemigrations and migrate commands. makemigrations creates migration files, while migrate applies those changes to the database schema.

2. What is the use of Django admin?
   The Django admin is an automatic interface for managing app data. It allows superusers to create, update, and delete data via a web-based interface.

3. How does Django handle security?
   Django protects against:

SQL Injection

Cross-Site Scripting (XSS)

Cross-Site Request Forgery (CSRF)

Clickjacking

User authentication

1. What is a QuerySet in Django?
   A QuerySet is a collection of database queries to retrieve objects from the database. QuerySets allow filtering, ordering, and chaining to refine query results.

2. What are Django middlewares?
   Middlewares are hooks that process requests and responses. They can be used for session management, authentication, or modifying requests/responses globally.

3. How can you define a URL pattern in Django?
   URLs are defined using the urls.py file:

python
Copy
Edit
from django.urls import path
from . import views

urlpatterns = [
path('home/', views.home, name='home'),
]

1. What is the difference between null=True and blank=True? null=True: Allows NULL values in the database.

blank=True: Field is allowed to be empty in forms.

1. What are class-based views (CBVs)?
   CBVs organize views using Python classes instead of functions. They allow code reusability and better organization.

2. How is static content handled in Django?
   Static files (like CSS, JS, images) are placed in a static/ directory. Django uses the collectstatic command to gather all static files in one place during deployment.

3. What is Django ORM?
   Django ORM allows developers to interact with databases using Python code instead of raw SQL.

4. How do you set up a Django project?
   Run:

bash
Copy
Edit
django-admin startproject projectname
cd projectname
python manage.py runserver

1. What is the use of manage.py?
   manage.py is a command-line utility that lets you interact with your project in various ways—running the server, migrating databases, creating superusers, and more.

2. Explain the use of settings.py.
   It’s the configuration file where database settings, installed apps, middleware, templates, and static paths are defined.

3. How does Django manage forms?
   Django provides both Form and ModelForm classes for creating and validating forms efficiently.

4. What is ModelForm?
   It’s a helper class that creates a form directly from a model. Saves time and ensures form fields align with the database structure.

5. What are signals in Django?
   Signals allow decoupled apps to get notified when certain actions occur (like post_save, pre_delete). Useful for logging or automating tasks.

6. What is a Django template tag?
   Template tags are used in HTML to perform logic inside templates, like looping or displaying conditional content.

7. What is the difference between @login_required and PermissionRequiredMixin?
   @login_required: Restricts view access to logged-in users.

PermissionRequiredMixin: Checks for specific user permissions.

1. How do you connect a Django project to a database other than SQLite?
   In settings.py, change the DATABASES dictionary to configure PostgreSQL, MySQL, or other database engines.

2. What are the common Django template filters?
   Examples include: date, length, lower, default, join, truncatechars, etc.

3. How does Django handle sessions?
   Django stores session data on the server side using middleware. Sessions can be stored in databases, cached memory, or files.

4. How do you deploy a Django application?
   Popular deployment options include:

Heroku

DigitalOcean

AWS EC2

Docker

Using gunicorn and nginx

1. What’s new in Django 4.x and what to expect in 2025? Some improvements include async view support, enhanced password validators, simplified form rendering, and upcoming features like enhanced typing, better ORM performance, and AI-driven code generation tools.
