Custom Extensions

With Django Extensions, you may make your custom extensions in addition to the widely used ones. With the help of these extensions, your Django project can have additional functionality or tedious activities automated.

Specifying a Python module with a particular structure is necessary to construct a custom extension. A class that extends the BaseCommand class from Django's core management commands ought to be included in the module. The handle() method, which is invoked when the extension is run, should be implemented by this class.

After defining your extension, add it to the INSTALLED_APPS list in the settings.py file of your Django project to use it. When you run administration commands, Django Extensions will find and load the custom extensions automatically. In addition to the widely used extensions, Django Extensions permits
