"""
This function gets the corresponding base classes in order to construct
the viewset class.
A model can specify the allowed operations to it, e.g. update,
list, delete, etc. Then, a viewset specify the allowed methods based on
model's allowed operations by defining the corresponding bases classes.
By default, all methods are allowed.
Apart from this, also configration object can also include custom mixins
classes. Therefore, they are also added to the list of bases classes.
:returns: A tuple of the corresponding base classes.
