javascript - DRF 在嵌套序列化器中创建用户

Question

大家好，我正在尝试通过 API 在 django Rest 框架中使用嵌套序列化器创建用户，但我遇到了一些问题:

这是我的代码:

class AffiliateRegisterSerializer(serializers.ModelSerializer):

class Meta:
    model = Affiliate
    fields = ('phone','address','state','city','ZIP','country','company','web_name','web_url','web_desc','payee_name','monthly_visits',)

和我的第二个序列化器:

class UserSerializer(serializers.ModelSerializer):

    '''
        Registering a new user with Affiliate Profile
    '''

    affiliate = AffiliateRegisterSerializer(required=False)

    class Meta:
        model = User
        fields = ('username','first_name','last_name','email','password','affiliate',)
        write_only_fields = ('password',)
        read_only_fields = ('id','affiliate',)

    def create(self, validated_data):
        affiliate_data = validated_data.pop('affiliate')
        user = User.objects.create_user(**validated_data)
        Affiliate.objects.create(user=user, **affiliate_data)
        return user

这是我的观点:

class AffiliateSignUp(generics.CreateAPIView):
    '''
        API endpoint for Affiliate Users registration
    '''

    queryset = User.objects.all()
    serializer_class = UserSerializer
    permission_classes = [permissions.AllowAny]

    @method_decorator(ensure_csrf_cookie)
    @method_decorator(csrf_protect)
    def create(self, request):
            serializer = UserSerializer(data=request.data)

            if serializer.is_valid():
                    serializer.save()
                    return JsonResponse(serializer.data, status=201)
            return JsonResponse(serializer.errors, status=400)

How can i send an POST request via AngularJS to create the user and the profile instantly?

我正在尝试通过 AngularJs POST 嵌套对象，但它说:

affiliate: ["This field is required."]

如果我通过 url:/api/affilaite 直接从后端进入，它会很好地注册用户，但我唯一遇到的问题是，

How to send the POST request with a nested object in javascript.

这是我的 JavaScript 代码:

data:$httpParamSerializerJQLike({
                'first_name':$scope.userData['first_name'],
                'last_name':$scope.userData['last_name'],
                'username':$scope.userData['username'],
                'password':$scope.userData['password'],
                'email':$scope.userData['email'],
                affiliate:{
                'phone':$scope.userData['phone'],
                'address':$scope.userData['address'],
                'state':$scope.userData['state'],
                'city':$scope.userData['city'],
                'ZIP':$scope.userData['ZIP'],
                'country':$scope.userData['country'],
                'company':$scope.userData['company'],
                'web_url':$scope.userData['webUrl'],
                'web_name':$scope.userData['webName'],
                'web_desc':$scope.userData['webDesc'],
                //'web_category':$scope.userData ['webCategory'],
                'payee_name':$scope.userData['payeeName'],
                'monthly_visits':$scope.userData['monthly_visits']
                }
              }

请帮助我:D 我正在挣扎:P

您有affiliate在序列化器中只读 Meta :read_only_fields = ('id','affiliate',) .

read_only

Read-only fields are included in the API output, but should not be included in the input during create or update operations. Any 'read_only' fields that are incorrectly included in the serializer input will be ignored.

Set this to True to ensure that the field is used when serializing a representation, but is not used when creating or updating an instance during deserialization.

Defaults to False
