django Manytomany字段插入空数据

Question

模型class Enrollee(TimeStampedModel):    id = models.UUIDField(primary_key=True, default=uuid.uuid4, verbose_name=_('id'))    first_name = models.CharField(max_length=60, verbose_name=_('first name'))    dependents = models.ManyToManyField(to=Dependant, blank=True, verbose_name=_('dependents'))class Dependant(TimeStampedModel):    id = models.UUIDField(primary_key=True, default=uuid.uuid4, verbose_name=_('id'))    first_name = models.CharField(max_length=60, verbose_name=_('first name'))看法class EnrolleeViewSet(viewsets.ModelViewSet):    queryset = models.Enrollee.objects.all()    serializer_class = serializers.EnrolleeSerializer    filter_class = filters.EnrolleeFilter序列化器class EnrolleeSerializer(DynamicFieldsMixin, DynamicFieldsModelSerializer):    dependents = DependantSerializer(many=True, required=False)    def create(self, validated_data):        dependant_data = validated_data.pop('dependents')        enrollee = models.Enrollee.objects.create(**validated_data)        for dependant in dependant_data:            models.Dependant.objects.create(**dependant)        return enrolleeclass Meta:    model = models.Enrollee    fields = '__all__'错误：  {  "first_name": "hmo1",  "dependents": [],  }这意味着家属没有插入在这里，我尝试为我的家属发送嵌套数据（ManyToManyField）但是，在插入数据时出现上述错误。我们有什么办法可以实现这一目标吗？{  "first_name":"soubhagya",  "dependents" : [     {       "first_name":"soubhagya"     }  ]}以上是我使用 post 方法发送的数据。请看一看

Answer 1

def create(self, validated_data):

    dependant_data = validated_data.pop('dependents')

    enrollee = models.Enrollee.objects.create(**validated_data)

    for dependant in dependant_data:

        obj = models.Dependant.objects.create(**dependant)

        enrollee.dependents.add(obj)

    enrollee.save()

    return enrollee
