Study Notes

Django Overview

Django is a full-stack development framework that provides a data access layer, presentation layer, and business logic layer.
The Model is the data access layer, which handles the database and data.
The View is the business logic layer, which interacts with the Model, executes business logic, and renders a template.
The Template is the presentation layer, which handles the user interface.

Flow of Control in MVT

The user sends a request to Django.
Django checks the URL and maps it to a View.
The View interacts with the Model to retrieve data.
The Model retrieves data from the database.
The View renders a template with the data.
Django sends the rendered template back to the user.

Characteristics of Django

Loosely Coupled: each element of the stack is independent of the others.
Less Code: Django ensures effective development with minimal code repetition.
Fast Development: Django offers fast and reliable application development.
Consistent Design: Django maintains a clean design and follows best web development practices.

Limitations of Traditional CGI Scripting

CGI scripting requires manual handling of headers, blank lines, and database connections.
Code reusability in multiple environments is difficult.
Redesigning the output page is complex.

Evolution of Django

Traditional web development involves writing multiple applications from scratch, refactoring code, and inventing a framework.
Django was born out of this process, providing a comprehensive framework for web development.

MVT (Model-View-Template) Pattern

The MVT pattern is a software design pattern that includes three components: Model, View, and Template.
The Model handles data access, the View handles business logic, and the Template handles presentation.
