How to create Django Rest Framework translate mixin?

Question

I'm trying to write a django translate mixin for my project. I configured the settings.py file, created a model, view, serializer and mixin. when I run the application an error occurs: "TranslationFieldMixin.get_field_names() missing 2 required positional arguments: 'declared_fields' and 'info'". This error occurred after I added this code to my serializer:

def to_representation(self, instance):
        language = get_language()
        self.fields = self.get_field_names(language=language)  
        return super().to_representation(instance)

How can I solve this problem?
