Description:
 def many_init(cls, *args, **kwargs):
 """ This method implements the creation of a `ListSerializer` parent class when `many=True` is used. You can customize it if you need to control which keyword arguments are passed to the parent, and which are passed to the child. Note that we're over-cautious in passing most arguments to both parent and child classes in order to try to cover the general case. If you're overriding this method you'll probably want something much simpler, eg: @classmethod def many_init(cls, *args, **kwargs):
 kwargs['child'] = cls() return CustomListSerializer(*args, **kwargs) """
