Django Rest Create with a Writable Nested Serializer

Hi everyone,

I'm trying to perform a create in Django Rest Framework using a writable nested serializer.

With the code bellow I can create a ScriptQuestion but I can't add a RecordedInterview into it. Django says OrderedDict is None.

What am I doing wrong?

Thanks in advance

#models.py    class ScriptQuestion(models.Model):      interview = models.ManyToManyField(RecordedInterview)      ...    class RecordedInterview(models.Model):      id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)      ...

The serializers

#serializers.py    class InterviewTitleSerializer(serializers.HyperlinkedModelSerializer):        class Meta:          model = RecordedInterview          fields = ('id', 'title')          extra_kwargs = {              'title': { 'read_only': True }          }      class QuestionDetailSerializer(serializers.HyperlinkedModelSerializer):        interview = InterviewTitleSerializer(many=True)        class Meta:          model = ScriptQuestion          fields = ('id', 'title', 'prep_time', 'answer_time', 'interview')          depth = 1        def create(self, validated_data):          interview_data = validated_data.pop('interview')          question = ScriptQuestion.objects.create(**validated_data)          for item in interview_data:              item = interview_data['id']              question.interview.add(item)          return question

Here is my view

#views.py     class CreateQuestion(generics.CreateAPIView):      queryset = ScriptQuestion.objects.all()      serializer_class = QuestionDetailSerializer

And the json

{      "title": "Question Test Json",      "prep_time": "1",      "answer_time":"1",      "interview": [             {                  "id": "a450aeb0-8446-47b0-95bd-5accbb8b4afa"              }       ]  }

If I do manually, I can add the RecordedInterview into the ScriptQuestion:

#serializers.py     def create(self, validated_data):      interview_data = validated_data.pop('interview')      question = ScriptQuestion.objects.create(**validated_data)      item = 'a450aeb0-8446-47b0-95bd-5accbb8b4afa'      question.interview.add(item)      return question
