Extending Project Zero

Django App or Package: Understanding Its Function

Django applications are parts of a django project. When developing a project, the project is divided into meaningful parts and the app is created for each part so that the complexity within the project is minimized and these parts of the application can be reused. You can follow the steps below to create a Django application.

Go to the project directory and run the following line of code.

$ python startapp demo

We created our application with the line of code that was run. Now let's examine the structure of the created application.

migrations/ The init file is a file that indicates that the folder it belongs to is a python module. Admin file is the file containing the settings related to the management panel. When we create a model, we use this file to provide the management interface of the model. App file is the file containing the settings related to the application. The models file is the layer where we create database objects and query. This is a file used for testing. The views file is the file in which we will write python functions related to views.

Migrations Directory: This folder is the folder that will hold the database structure of the application.
