Question

我的django模型如下所示：

class ExhibitionSurveyObjectSerializer(serializers.ModelSerializer):

    class Meta:
        model = ExhibitionSurveyObject
        fields = '__all__'

    def create(self, validated_data):
        return ExhibitionSurveyObject.objects.create(**validated_data)

    def update(self, instance, validated_data):
        instance.name = validated_data.get('name', instance.name)
        instance.farmer_email = validated_data.get('farmer_email', instance.farmer_email)
        instance.farmer_name = validated_data.get('farmer_name', instance.farmer_name)
        instance.address = validated_data.get('address', instance.address)
        instance.postal_code = validated_data.get('postal_code', instance.postal_code)
        instance.size = validated_data.get('size', instance.size)
        instance.path = validated_data.get('path', instance.path)
        instance.object_type = validated_data.get('object_type', instance.object_type)
        instance.cycle = validated_data.get('cycle', instance.cycle)
        instance.save()
        return instance

我有一个序列化器：

class ExhibitionSurveyObjectForm(forms.ModelForm):
    owner = CustomUserChoiceField(queryset=User.objects.all())
    class Meta:
        model = ExhibitionSurveyObject
        fields = "__all__"

我的表单：

class ExhibitionSurveyObjectList(generics.ListCreateAPIView):
    queryset = ExhibitionSurveyObject.objects.all()
    serializer_class = ExhibitionSurveyObjectSerializer

    def perform_create(self, serializer):
    serializer.save(owner=self.request.user)

我的观点：

addObject(

    name: string, 
    farmer_email: string,
    farmer_name: string,
    size: string,
    path: Array<google.maps.LatLngLiteral>, 
    cycle: string, 
    object_type: string) {
    let obj = new ExhibitionSurveyObjectModel(name, farmer_email, farmer_name, size, path, cycle, object_type);

    let body = JSON.stringify(obj);
    let headers = new Headers({ 'Content-Type': 'application/json; charset=utf-8', 'Authorization': 'Token ' + localStorage.getItem('auth_token') });
    let options = new RequestOptions({ headers: headers });
    console.log(body);
    return this.http.post(this._exhibitionSurveyObjectURL, body, options)
                    .map(this.extractData)
                    .catch(this.handleError)
  }

我有一个Ionic2前端，我的服务有以下功能来保存上述模型的实例：

export class ExhibitionSurveyObjectModel {
  constructor(
    public name: string, 
    public farmer_email: string,
    public farmer_name: string,
    public size: string,
    public path: Array<google.maps.LatLngLiteral>, 
    public cycle: string, 
    public object_type: string, 
    public owner: string
    ){}
}

我的客户端也有一个模型：

{"owner":["This field is required."]}

正如我可以看到令牌被发送到后端，但我收到了回复{{1}}

发送令牌还不够吗？如果我必须通过＆＃39; 所有者＆＃39;以及我的服务请求应该是什么价值（但是，我认为令牌应该足够了）？

或者我在后端遗漏了什么？

我的猜测是问题是您正在错误地创建序列化程序。您具体指明使用__all__字段，这意味着所有字段。与此无关，但您不应该真的需要在模型serielizer上创建或更新。

相反，尝试这样的事情

class ExhibitionSurveyObjectSerializer(serializers.ModelSerializer):
    class Meta:
        model = ExhibitionSurveyObject
        fields = ('name', 'farmer_email', 'farmer_name', 'address', 
                  'postal_code', 'size', 'path', 'object_type', 
                  'cycle')
        read_only_fields = ('owner', )

这应该是你所需要的一切。

Django拒绝来自客户端的不成功请求
