Unlock the Secrets of Django Architecture: A Beginner’s Guide
Django follows the model-template-view (MTV) architectural pattern, which is similar to the model-view-controller (MVC) pattern. In this pattern, the Model represents the data and the business logic of the application, the template defines the user interface, and the View handles the input and output of the application.
Here’s a high-level description of how the MTV pattern’s many components interact in Django:
- Models: In Django, models represent the data of your web application and define the structure of the data in the database. You can use Django’s object-relational mapper (ORM) to interact with your models and manipulate the data stored in the database.
- Templates: Django’s template engine allows you to define the user interface of your web application using HTML, CSS, and JavaScript. Templates are responsible for rendering the final output that is sent to the user’s web browser.
- Views: Views handle the input and output of your web application. They receive requests from the user’s web browser and return the appropriate response, which could be a dynamic web page, a redirect, or an error message.
- URLs: Django uses URL patterns to route requests to the appropriate View. When a user requests your web application, Django determines which View should handle the request based on the URL patterns you’ve defined.
MVC architecture is commonly used when discussing apps that provide UI (web or desktop). Model, View, and Controller are the three components of the MVC pattern.
The Model defines the data structure and handles database queries.
The View specifies the data to be shown and produces an HTTP response.
The Controller is the component of the application in charge of user interaction.
Model-View-Template (MVT) is a distinct idea from MVC. The primary distinction between these two architectural patterns is that Django oversees the Controller component. The template is an HTML file that has been combined with a Django Template Language (DTL) file.
Overall, Django’s MTV architecture makes it easy to separate the different components of your web application and to develop and maintain complex, database-driven websites.
