I am getting a JSON input with the fields description and choices for a Question model. The Choice model also has a foreign key field pointing to Question with a related name of choices. However, in the JSON, the Choice will come without the question_id field, in order to be assigned after the creation of the Question

I am getting all kind of errors when trying to create a Question and then assigning all incoming to it. Searched a lot for the error Direct assignment to the forward side and didn’t found anything that solves my problem

I can’t change the related name and the JSON input fields, if this was a possibility I’d have already done it

class CreateQuestionSerializer(serializers.ModelSerializer):
    description = serializers.CharField(max_length=1024, allow_blank=False, required=True)
    choices = CreateChoiceSerializer(many=True, required=True)

    def create(self, validated_data):
        choices = validated_data.pop('choices')

        question = Question.objects.create(**validated_data)

        choices_serializer = CreateChoiceSerializer(data=choices, many=True, context={'question': question})
            if choices_serializer.is_valid():
                choices_serializer.save()
        
        return question
