An AdminSite object encapsulates an instance of the Django admin application, ready
to be hooked in to your URLconf. Models are registered with the AdminSite using the
register() method, and the get_urls() method can then be used to access Django view
functions that present a full admin interface for the collection of registered
models.

Register the given model(s) with the given admin class.
The model(s) should be Model classes, not instances.
If an admin class isn't given, use ModelAdmin (the default admin
options). If keyword arguments are given -- e.g., list_display --
apply them as options to the admin class.
If a model is already registered, raise AlreadyRegistered.
If a model is abstract, raise ImproperlyConfigured.

Decorator to create an admin view attached to this ``AdminSite``. This
wraps the view and provides permission checking by calling
``self.has_permission``.
You'll want to use this from within ``AdminSite.get_urls()``:
class MyAdminSite(AdminSite):
def get_urls(self):
from django.urls import path
urls = super().get_urls()
urls += [
path('my_view/', self.admin_view(some_view))
]
return urls
By default, admin_views are marked non-cacheable using the
``never_cache`` decorator. If the view can be safely cached, set
cacheable=True.
