What does the MVC pattern refer to in Django?
In Django, the MVC pattern refers to the Model-View-Controller pattern, which is a software architectural design pattern. In this pattern, the system is divided into three parts: the Model, View, and Controller.
- Model: responsible for handling the data logic of the application, interacting with the database, and performing operations such as data access.
- View: responsible for presenting data to users, handling user requests and responses, rendering templates, and so on.
- Controller: responsible for handling user requests, invoking model to process data logic, and passing the results to the view layer.
In Django, a pattern similar to MVC called MTV (Model-Template-View) is actually used, where the model corresponds to Model, the template corresponds to View, and the view corresponds to Controller. This pattern makes the code easier to maintain and expand, with clear responsibilities for each part, leading to more efficient and clear development.
