第一种方法

from rest_framework.views import APIView
class all_classroom(APIView):
    def get(self,request):
        classroom = Classroom.objects.all()
        ser = serailizers_classroom(classroom,many=True)
        return Response(ser.data,status=200)


class  single_classroom(APIView):
    def get(self,request,pk):
        classroom = Classroom.objects.get(pk=pk)
        ser = serailizers_classroom(classroom)
        return Response(ser.data,status=200)
    def put(self,request,pk):
        classroom = Classroom.objects.get(pk=pk)
        ser = serailizers_classroom(classroom,data=request.data)
        if ser.is_valid():
            ser.save()
            return Response(ser.data,status=200)
        return Response(ser.errors)
    def delete(self,request,pk):
        classroom = Classroom.objects.get(pk=pk)
        classroom.delete()
        return Response(status=200)

from django.conf.urls import url
from django.contrib import admin
from django.urls import path, include

from day1106_app import urls

urlpatterns = [
    path('admin/', admin.site.urls),
    url('^', include(urls)),
]
## 子url设置

第二种方法

from rest_framework.generics import GenericAPIView
from rest_framework import mixins

    def get(self,request):
        return self.list(request)
    def post(self,request):
        return self.create(request)

rout.register('classroom',all_classroom)
rout.register('students',all_students)
urlpatterns = [
    url('^$', TemplateView.as_view(template_name='index.html')),
]
urlpatterns += rout.urls
