Django is a high-level Python web framework used to build secure, scalable, and fast web applications.
It helps developers create web applications quickly by providing built-in tools and features.
Django follows the principle:
“Don’t Repeat Yourself (DRY)”
This means writing clean and reusable code.
Why Use Django?
Django is popular because:
- It is built with Python
- It is fast and secure
- It has built-in authentication
- It includes an admin panel
- It follows best development practices
- It is scalable for large applications
Many large websites use Django.
What Type of Applications Can Be Built?
With Django, you can build:
- Business websites
- E-commerce platforms
- Social media apps
- Learning management systems
- APIs
- Dashboards
Django Architecture (MVT Pattern)
Django follows the MVT architecture:
Model
View
Template
1. Model
- Handles database
- Defines data structure
- Interacts with database
Example:
User, Product, Order tables
2. View
- Contains business logic
- Processes requests
- Returns responses
3. Template
- Handles frontend display
- Uses HTML
- Shows dynamic data
How Django Works
- User sends request
- URL dispatcher routes request
- View processes logic
- Model interacts with database
- Template renders data
- Response sent to browser
