Question

下面是我的urls.py，我需要指定有效负载的结构并在每个请求中指定标头

    from django.conf.urls import url, include
    from rest_framework.routers import DefaultRouter
    from . import views

    router = DefaultRouter()

    router.register("patient", views.PatientsApiView)

    urlpatterns = [
        url(r'', include(router.urls))

     ]

以下是我的观点。py 我使用模型viewset制作了一个视图，使用通用API视图制作了另一个视图

class PatientsApiView(viewsets.ModelViewSet):
    model = Patient
    fields = ("id",  "first_name", "last_name", "phone", "email", "created_at")

"""
Create a serializer in serializer.py

class EmbryoSerializer(serializers.ModelSerializer):
    class Meta:
        model = Embryo
        fields = ("id", "name", "analysis_result", "created_at", "patient")

"""

class EmbryoApiView(APIView):
    def get(self, request, format=None):
        embryo = Embryo.objects.all()
        serializer = EmbryoSerializer(embryo, many=True)
        return Response(serializer.data)

    def post(self, request, format=None):
        serializer = EmbryoSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

    def put(self, request, pk, format=None):
        embryo = self.get_object(pk)
        serializer = EmbryoSerializer(embryo, data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

    def patch(self, request, user_id):
        user = User.objects.get(id=user_id)
        serializer = EmbryoSerializer(embryo, data=request.data, partial=True)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
router.register("embryo", views.EmbroApiView)

您认为我如何在views.py中实现这一目标

Answer 1

最好在views.py和serializers.py

中为每个请求指定有效负载和标头的结构

有效载荷将在序列化器中验证。您可以简单地将标头传递给Response（）。例如 return Response( … , headers={'My-Header': 'hello'})将添加标题。

示例：

class EmbryoApiView(APIView):
    def get(self, request, format=None):
        embryo = Embryo.objects.all()
        serializer = EmbryoSerializer(embryo, many=True)
        return Response(serializer.data, headers={'My-Header': 'Below are all the embroys for this patient'})

如何在每个请求Django URLS中指定有效负载的结构并指定标头
