To use use different serializers in the same ModelViewSet with Python Django rest framework, we can add the get_serializer_class into a mixin.
For instance, we write
def get_serializer_class(self):
try:
return self.serializer_action_classes[self.action]
except (KeyError, AttributeError):
return super(MultiSerializerViewSetMixin, self).get_serializer_class()
to add the get_serializer_class method.
In it, we look for serializer class in self.serializer_action_classes, which should be a dict mapping action name (key) to serializer class (value).
And if there’s no entry for that action then just fallback to the regular get_serializer_class lookup by returning self.serializer_class, DefaultSerializer.
