Question

我将以下JSON GET请求发送到定义产品配置的服务器： {'currency': ['"GBP"'], 'productConfig': ['[{"component":"c6ce9951","finish":"b16561c9"},{"component":"048f8bed","finish":"b4715cda"},{"component":"96801e41","finish":"8f90f764"},{"option":"6a202c62","enabled":false},{"option":"9aa498e0","enabled":true}]']}

我正在尝试通过DRF验证这一点，我有以下配置：

views.py

class pricingDetail(generics.ListAPIView):
    authentication_classes = (SessionAuthentication,)
    permission_classes = (IsAuthenticated,)
    parser_classes = (JSONParser,)
    def get(self, request, *args, **kwargs):
            pricingRequest = pricingRequestSerializer(data=request.query_params)
            if pricingRequest.is_valid():
                return Response('ok')

serializers.py

class pricingComponentSerializer(serializers.ModelSerializer):
    class Meta:
        model = Component
        fields = ('sku',)

class pricingFinishSerializer(serializers.ModelSerializer):
    class Meta:
        model = Finish
        fields = ('sku',)

class pricingOptionSerializer(serializers.ModelSerializer):
    class Meta:
        model = ProductOption
        fields = ('sku',)

class pricingConfigSerializer(serializers.ModelSerializer):
    finish = pricingFinishSerializer(read_only=True, many=True)
    component = pricingComponentSerializer(read_only=True, many=True)
    option = pricingOptionSerializer(read_only=True, many=True)
    enabled = serializers.BooleanField(read_only=True)


class pricingCurrencySerializer(serializers.ModelSerializer):
    class Meta:
        model = Currency
        fields = ('currencyCode',)

class pricingRequestSerializer(serializers.Serializer):
    config = pricingConfigSerializer(read_only=True)
    currency = pricingCurrencySerializer(read_only=True)

正如您所看到的，我正在尝试通过使用内联序列化程序在同一请求中验证多个模型。

我的问题 上面的代码允许所有内容都通过is_valid()（即使我发出无效请求，它也会返回一个空的validated_data（OrderedDict([])）值。

我做错了什么？

额外信息

生成GET请求的JS如下： this.pricingRequest = $.get(this.props.pricingEndpoint, { productConfig: JSON.stringify(this.state.productConfig), currency: JSON.stringify(this.state.selectedCurrency) }, function (returnedData, status) { console.log(returnedData);

我目前没有计算机来浏览源代码，但您可能需要检查序列化程序上的read_only参数。 Afaik这仅适用于在回复中显示数据。

您可以使用ipdb轻松检查（ipython调试器）只是说：

import ipdb; ipdb.set_trace()

您想要开始调试，启动服务器并启动请求。

Django REST框架 - is_valid（）总是传递并返回空的validated_data
