class django.views.generic.list.MultipleObjectMixin¶ A mixin that can be used to display a list of objects. If paginate_by is specified, Django will paginate the results returned by this. You can specify the page number in the URL in one of two ways: Use the page parameter in the URLconf.

The ServiceProvidersOnly mixin inherits from the LoginRequired class which is a mixin for applying the login_required decorator.

These types of classes aren't usually instantiated or used on their own other than to be extended from so that other classes can use the functionality they provide. In the example, sometimes the "Cannot make decisions based on self.access_a nor self.access_long" exists in yet another mixin, as the pattern is repeated across a large number of views. We find the duplication increases the maintenance burden as when writing a new new views, the developer must remember to include these repetitive calls. However, in Python the class hierarchy is defined right to left, so in this case the Mixin2 class is the base class, extended by Mixin1 and finally by BaseClass.This is usually fine because many times the mixin classes don't override each other's, or the base class' methods. The method handlers for a ViewSet are only bound to the corresponding actions at the point of finalizing the view, using the .as_view() method.
