Introduction to Django
Django is a powerful and high-level Python web framework used for building secure, scalable, and maintainable web applications. It follows the MVT (Model-View-Template) architecture and provides many built-in features that help developers build web applications quickly.
Django is widely used by companies and platforms such as Instagram, Pinterest, and Mozilla because of its scalability, security, and rapid development capabilities.
What is Django?
Django is an open-source Python web framework designed to simplify the development of complex web applications. It follows the principle of "Don't Repeat Yourself (DRY)", which encourages code reuse and clean architecture.
Django provides built-in tools for handling common web development tasks such as:
- User authentication
- Database management
- URL routing
- Form validation
- Security protection
- Admin dashboard
Key Features of Django
- Fast development with built-in components
- Secure framework with protection against common attacks
- Scalable architecture for large applications
- Built-in admin interface
- ORM (Object Relational Mapping) for database operations
- Reusable apps and modular design
Django Architecture (MVT Pattern)
Django follows the Model-View-Template (MVT) architecture.
| Component | Description |
|---|---|
| Model | Handles database structure and data operations |
| View | Contains business logic and processes requests |
| Template | Handles the presentation layer and renders HTML pages |
This architecture helps separate business logic from user interface code.
Installing Django
Django can be installed using the Python package manager pip.
After installation, you can verify the version using:
Creating a Django Project
A Django project can be created using the following command:
This command creates the project folder and necessary configuration files.
Project Structure
myproject/
│
├── manage.py
│
└── myproject/
├── __init__.py
├── settings.py
├── urls.py
├── asgi.py
└── wsgi.py
Important files include:
- manage.py – Command-line utility for managing the project
- settings.py – Configuration file for the project
- urls.py – Handles URL routing
- wsgi.py – Used for deployment
Running the Development Server
To start the Django development server, navigate to the project directory and run:
Open your browser and visit:
http://127.0.0.1:8000
If Django is installed correctly, you will see the Django welcome page.
Creating a Django App
Django applications are modular components inside a project. To create an app, run:
This command creates a new app structure.
