Question

在我的DRF中，我想在视图中映射客户/服务关系。因此，一个客户可以拥有0个服务-

受How to join two models in django-rest-framework启发，我的序列化程序类似乎还不错


class CustomerSerializer(serializers.ModelSerializer):

    class Meta:

        model = Customer 
        fields = ['name' , 'phone' ,'email1' ... , 'service_id'] 


class ServiceSerializer(serializers.ModelSerializer):
    class Meta:
        model = Service 
        fields = ['service_name', 'product_name', ...]


class Customer_ServiceSerializer(serializers.ModelSerializer):

    service = ServiceSerializer(many=True, read_only=True)
    class Meta:
        model = Customer
        fields = ['name' , 'phone1' , 'email1' ... 'service']

我的Customer_ServiceSerializer类似乎正确嵌套了

由于我尝试了多种方法并陷入困境，我陷入了如何在视图中显示这些组合模型的问题


class Customer_serviceListAPIView(generics.ListAPIView):
...

def get(self, request, *args, **kwargs):

以上是我开始发表意见的方式，但我仍然坚持如何解决此问题

例如，尝试了此Serialize multiple models in a single view / https://simpleisbetterthancomplex.com/tips/2016/06/20/django-tip-5-how-to-merge-querysets.html

但是我得到了客户对象，因此无法迭代

预先感谢

修改


class Customer_serviceListAPIView(generics.ListAPIView):
    permission_classes = (IsAuthenticated,)
    queryset = Customer.objects.all()
    serializer_class = Customer_ServiceSerializer
    lookup_field= "name"

需要在视图中做点什么吗？按照目前的样子，它将只显示带有service_id的客户而不是服务详细信息所以我需要做些额外的事情才能使它像这样
