Top Django Questions and Answers

1. What is Client-Server Architecture? Explain with example.

Client-Server Architecture is a computing model where multiple clients request services from a centralized server.

Client: A user interface such as a web browser
Server: A system that processes requests and returns responses

Example:

When you type a URL in your browser:

The browser (client) sends a request to the server
The server processes the request and returns the webpage

Advantages:

Centralized data control
Easy maintenance
Supports multiple users simultaneously

2. Explain the MVT architecture in Django.

Django follows the MVT (Model-View-Template) pattern.

Model: Manages database and data structure
View: Contains business logic
Template: Displays data to the user

Flow:

User → URL → View → Model → Template → Response

Why it is useful:

Separates logic from presentation
Improves code readability
Speeds up development

3. How is MVT different from MVC architecture?

In MVC:

Model → Data
View → UI
Controller → Logic

In Django (MVT):

Model → Data
View → Logic
Template → UI

Key Difference:

Django internally handles the controller, reducing complexity.

4. What is URL configuration in Django? Explain with example.

URL configuration connects URLs to views.

Example:

from django.urls import path
from . import views

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

Explanation:

When user visits /home/, Django calls views.home

5. Explain the steps to install Django and create a project.

Step 1: Install Django

pip install django

Step 2: Create Project

django-admin startproject myproject
cd myproject

Step 3: Run Server

python manage.py runserver

Output:

The development server starts at:

http://127.0.0.1:8000/

6. What is Django development server? Analyze its working.

The development server is a lightweight web server used for testing.

Features:

Automatically reloads on code changes
Handles HTTP requests
Displays errors for debugging

Limitation:

Not suitable for production use

7. What are Django Models? Explain their purpose with example.

Models define database structure using Python classes.

Example:

from django.db import models

class Student(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField()

Purpose:

Store data
Perform database operations
Use ORM instead of SQL

8. Explain CRUD operations in Django with example.

CRUD stands for:

Create

Student.objects.create(name="Amit", age=20)

Read

Student.objects.all()

Update

student.age = 21
student.save()

Delete

student.delete()

Importance:

Used to manage data in applications

9. How are models connected with views and templates?

Flow:

Model stores data
View retrieves data
Template displays data

Example:

def home(request):
    students = Student.objects.all()
    return render(request, 'home.html', {'students': students})

Template:

{% for s in students %}
    {{ s.name }}
{% endfor %}

10. What is Django Template System?

It is used to generate dynamic HTML pages.

Features:

Variables
Loops
Conditions

Example:

<h1>{{ name }}</h1>

11. Explain template inheritance in Django.

Template inheritance allows reuse of code.

Example:

{% extends "base.html" %}
{% block content %}
Hello
{% endblock %}

Advantage:

Avoids repetition
Maintains consistency

12. What are template filters? Give examples.

Filters modify data before display.

Examples:

{{ name|upper }}
{{ name|lower }}
{{ list|length }}

13. What is context in Django templates?

Context is a dictionary used to pass data from views to templates.

Example:

{'name': 'Kavita'}

Used in template:

{{ name }}

14. What is form validation in Django?

Form validation checks correctness of user input.

Example:

if form.is_valid():
    form.save()

Benefits:

Prevents invalid data
Ensures data integrity

15. Explain GET and POST methods in Django.

Method	Purpose
GET	Retrieve data
POST	Submit data

Example:

if request.method == 'POST':
    form = Form(request.POST)

16. How to create and handle forms in Django?

Form Example:

from django import forms

class StudentForm(forms.Form):
    name = forms.CharField()

Handling Form:

if request.method == 'POST':
    form = StudentForm(request.POST)

17. Explain custom validation in Django forms.

Custom validation is done using clean() methods.

Example:

def clean_name(self):
    name = self.cleaned_data['name']
    if len(name) < 3:
        raise ValidationError("Too short")
    return name

18. How do you render dynamic content using templates?

Dynamic content is passed using context.

Example:

return render(request, 'home.html', {'name': 'Student'})

Template:

<h1>{{ name }}</h1>
