APIView视图的序列化器继承ModelSerializser

一、在serializser.py编写序列化器继承于ModelSerializser

from .models import Publish

class PublishSerializer(serializers.ModelSerializer):
    class Meta:
        model = Publish
        fields = "__all__"

二、在views.py编写类视图继承于APIView

from .models import Author, Publish
from .serializers import AuthorSerializer, PublishSerializer

class PublishView(APIView):
    def get(self, request):
        publishs = Publish.objects.all()  #获取所有数据
        serializer = PublishSerializer(instance=publishs, many=True)   #构建序列化器
        return Response(serializer.data)

    def post(self, request):
        serizlizer = PublishSerializer(data=request.data)    #反序列化器
        #数据校验
        #验证通过   serializer.data
        #验证不通过  serializer.errors
        if serizlizer.is_valid():
            # Author.objects.create(**serializer.validated_data)   这种原始传入数据的方法
            # return Respons("OK")
            serizlizer.save()
            return Response(serizlizer.data)
        else:
            return Response(serizlizer.errors)


class PublishDetailView(APIView):
    def get(self, request, pk):
        publish = Publish.objects.get(pk=pk)
        serializer = PublishSerializer(instance=publish,many=False)
        return Response(serializer.data)

    def put(self, request, pk):
        publish = Publish.objects.get(pk=pk)
        serializer = PublishSerializer(instance=publish, data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        else:
            return Response(serializer.errors)

    def delete(self, request, pk):
        Publish.objects.get(pk=pk).delete()
        return Response()

三、在urls.py增加路由表

from .views import PublishView, PublishDetailView

urlpatterns = [
   path('publish/', PublishView.as_view()),
   re_path('publish/(?P\d+)/', PublishDetailView.as_view())
]

四、测试

get post
http://127.0.0.1:8000/stu/publish

put delete get
http://127.0.0.1:8000/stu/publish/1/
