If you are trying to basically just add extra piece of information into the serialized object, you don't need to change the fields part at all. To add a field you do:

class MySerializer(serializers.ModelSerializer):
   ...
   new_field = serializers.SerializerMethodField('new_field_method')

   def new_field_method(self, modelPointer_):
      return "MY VALUE"

Then you can still use

class Meta:
   fields = '__all__'
