django - Unable to delete record in DB when using DestroyAPIView -

i'm trying write django rest framework based backend learning purpose.

i've created simple school model, has name , description field (please note primary key auto populated).

app's models.py data below,

from django.db import models  class school(models.model):     name = models.charfield(max_length=255)     description = models.textfield()  class meta:     ordering = ('id',)  def __str__(self):     return self.name 

app's views.py data below,

from .models import school .serializers import schoolserializer rest_framework import status rest_framework import generics rest_framework.decorators import permission_classes rest_framework.permissions import isadminuser rest_framework.response import response   class schoollist(generics.listcreateapiview):     queryset = school.objects.all()     serializer_class = schoolserializer     permission_classes(isadminuser,)      def list(self, request, *args, **kwargs):         queryset = self.get_queryset()         serializer = schoolserializer(queryset, many=true)         return response(serializer.data)      @permission_classes((isadminuser, ))     def post(self, request, format=none):         user = request.user         serializer = schoolserializer(data=request.data, context={'user':user})         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)   class schooldetail(generics.retrieveapiview):     queryset = school.objects.all()     serializer_class = schoolserializer   class schooldelete(generics.destroyapiview):     queryset = school.objects.all()     serializer_class = schoolserializer       def delete(self, request, *args, **kwargs):         return self.destroy(request, *args, **kwargs) 

app's urls.py data below,

from django.conf.urls import url rest_framework.urlpatterns import format_suffix_patterns . import views   urlpatterns = (     url(r'^schools/$', views.schoollist.as_view()),     url(r'^schools/(?p<pk>[0-9]+)/$', views.schooldetail.as_view()),     url(r'^schools/delete/(?p<pk>[0-9]+)/$', views.schooldelete.as_view()), )  urlpatterns = format_suffix_patterns(urlpatterns) 

i'm trying delete particular school entry using delete rest api call,

http --json delete http://127.0.0.1:8000/schools/delete/1 http/1.0 301 moved permanently content-type: text/html; charset=utf-8 date: tue, 12 sep 2017 16:06:58 gmt location: /schools/delete/1/ server: wsgiserver/0.2 cpython/3.5.2 

after doing when check school list using api (http://127.0.0.1:8000/schools/), see school record not being deleted.

what mistake here?
