Django REST Framework Serializers - to_internal_value()

DRF tip:

If your API receives unnecessary data, you can override to_internal_value() to extract the resource data.

For example:

class ResourceSerializer(serializers.ModelSerializer):
    # ...

    def to_internal_value(self, data):
        resource_data = data['resource']

        return super().to_internal_value(resource_data)
