Suppose you have a viewset for a Detail model that doesn't inherit from the Master viewset (ContentViewset in this case):

class DistributionTreeViewSet(NamedModelViewSet,
                              mixins.RetrieveModelMixin,
                              mixins.ListModelMixin,
                              mixins.DestroyModelMixin):
    """
    Distribution Tree Viewset.
    """

    endpoint_name = 'distribution_trees'
    queryset = DistributionTree.objects.all()
    serializer_class = DistributionTreeSerializer

Pulp will automatically try to define the endpoint using master_endpoint (which doesn't exist), app_label, and endpoint_name. In this case, this ends up being "/pulp/api/v3/distribution_trees/rpm/distribution_trees/" which is probably not what the plugin writer wants.
