python - DRF 序列化器深度使字段在创建时被忽略

Question

(project is available on github with that problem)

出于某种原因，序列化程序的深度选项会在创建时忽略字段。

序列化器:

class AnswerSerializer(serializers.ModelSerializer):

    class Meta:
        model = Answer
        fields = ('question', 'body',)
        depth = 1

查看:

class AnswerList(ListCreateAPIView):
    queryset = Answer.objects.all()
    serializer_class = AnswerSerializer

当我尝试使用 depth = 1 创建答案时，我得到 NOT NULL constraint failed: forum_answer.question_id，但是当我注释掉 depth = 1 一切正常。但是当然我没有得到完整的 Question 对象，只有它的 pk。

现在序列化器看起来像这样:

class AnswerSerializer(serializers.ModelSerializer):
    question_pk = serializers.PrimaryKeyRelatedField(
        queryset=Question.objects.all(), source='question', write_only=True
    )

    class Meta:
        model = Answer
        fields = ('question', 'question_pk', 'body',)
        depth = 1
