Question

我前面有从串行器中获取的数据，除了丢失了两个数据“用户”和“场所”。

const workplaceBody = {
  "user": this.currentUser.id,
  "establishment": response.body.id,
  "is_main_establishment": false
};

当我在序列化程序中打印validated_data时，我只有一个“ is_main_ Establishment”数据。

{'is_main_establishment': False}

我想创建一个与企业关联的工作场所。

this.workplaceEstablishment.create(workplaceBody).subscribe(response => {
  console.log(response);
});

我的工作场所序列化器：

class WorkplacesSerializer(ModelSerializer):
    id = IntegerField(source="establishment.id", read_only=True)
    name = CharField(source="establishment.name", read_only=True)
    type = CharField(source="establishment.type", read_only=True)
    selected = SerializerMethodField()

    def get_selected(self, instance):
        #print(instance)
        #print(self.context["request"].data)
        return (
            get_selected_establishment_id_from_request(self.context["request"])
            #"== instance.id
        )

    def create(self, validated_data):
        print(validated_data)
        workplace = UserWorksAtEstablishment.objects.create(
            **validated_data, establishment_id=validated_data.establishment, user_id=validated_data.user
        )
        return workplace
    class Meta:
        model = UserWorksAtEstablishment
        fields = ("id", "name", "type", "is_main_establishment", "selected")

我不明白为什么我会丢失这些数据。

提前谢谢

确保user和establishment是表的模型中的字段，然后可以通过执行以下操作将它们添加到序列化器中：

class Meta:
    model = UserWorksAtEstablishment
    fields = ("id", "user", "establishment", "name", "type", "is_main_establishment", "selected")

或仅添加所有字段：

    class Meta:
        model = UserWorksAtEstablishment
        fields = '__all__'

我在序列化程序中丢失数据（Django / Angular）
