小编Gau*_*kla的帖子

这些是我的模型和序列化器.我想要一个问题模型的表示以及要求问题的人员列表.

我在尝试这个:

@api_view(['GET', 'PATCH'])
def questions_by_id(request,user,pk):
    question = Question.objects.get(pk=pk)
    if request.method == 'GET':
        serializer = QuestionSerializer(question)
        return Response(serializer.data)

但我得到一个空字典({}).但是当我asked从中移除字段时,QuestionSerializer我会得到一个完整的表示Question以及Places序列化.我错过了什么？

class AskedToSerializer(serializers.ModelSerializer):
    class Meta:
        model = AskedTo
        fields = ('to_user', 'answered')

class QuestionSerializer(serializers.ModelSerializer):
    class Meta:
        model = Question
        places = PlaceSerializer(many=True, required=False)
        asked = AskedToSerializer(source='askedto_set', many=True)
        fields = ('id', 'created_on', 'title', 'places', 'answered','asked')
        extra_kwargs = {'created_by': {'read_only': True}}

class Question(BaseModel):
    title = models.CharField(max_length=200, null=False)
    places = models.ManyToManyField(Place, blank=True)
    answered = models.BooleanField(default=False) …
