Django Introduction
Django is a high-level web framework that encourages rapid development and clean, pragmatic design.
Django is an open-source and free to use, maintained by the Django Software Foundation.
Features and benefits of Django:
- Object-relational mapping (ORM): Python objects can be used in place of SQL queries making it simpler for developers when dealing with database models. In most cases, writing SQL queries is unnecessary.
- Admin interface: The application's models automatically generate a robust admin interface. Notably, developers and administrators can create, read, update or delete data without having to write more code on the admin interface for managing site content.
- Security: Django has an inbuilt protection system against common security threats such as; Cross-site scripting (XSS), cross-site request forgery (CSRF), SQL injection among many others.
- Scalability: Django’s architecture design is meant to scale enabling developers to handle high traffic and large datasets better.Optimally,this supports caching,database replication,and load balancing that altogether increase performance!
- Comes with Batteries: Authentication, URL routing, form handling and database management are some of the commonly done web development tasks which built-in features that come with Django. This makes the rate at which a project develops to speed up and creates uniformity!
Understanding Django's architecture (MVC - Model View Controller):
Django follows the Model-View-Controller (MVC) architectural pattern, although it refers to it slightly differently:
Model: The data structure of the application is designated by the model layer and it keeps the business logic inside. This can be done in Django with help of models, which are Python class that define how database tables look like and contain some ORM code for interaction with a database.
View: The user interface has to be displayed and users’ requests should be taken on by the view layer. In Django, views are Python functions/codes or classes which get HTTP requests and give back HTTP responses. They link up with templates via models for getting information then rendering pages.
Template: Templates in Django create dynamic HTML pages from data passed to them by views. Templates in Django are HTML files where some additional Python code is embedded using Django’s template language to allow dynamic content rendering.
