GenericAPIViewSet 示例

  1. GenericAPIViewSet(ViewSetMixin, generics.GenericAPIView):
  3. # urls.py
  4. # url(r^'(P?<version>[v1|v2]+/v1/$)', views.View1View.as_view({'get': 'list'})
  8. from api.utils.serializsers.pager import PagerSerialiser 
  9. from rest_framework.viewsets import GenericAPIViewSet
  11. class ViewlView(GenericAPIViewSet)：
  12.     queryset=models.Role.objects.al1()
  13.     serializer_class=PagerSerialiser 
  14.     pagination_class=PageNumberPagination 
  17.     def list(self,request，*args，**kwargs)：
  18.         # 获取数据
  19.         roles=self.get_queryset() #models.Role.objects.all()
  21.         # 分页 [1，1880，][1，10]
  22.         pager_roles=self.paginate_queryset(roles)
  23.         ser=self.get_serializer(instance=pager_roles,many=True)
  25.         return Response(ser.data)

ModelViewSet 源码

  1. class ModelViewset(mixins.createModelMixin, 
  2.                     mixins.RetrieveModelMixin, 
  3.                     mixins.UpdateModelMixin, 
  4.                     mixins.DestroyModelMixin, 
  5.                     mixins.ListModelMixin, 
  6.                     GenericViewSet):
  8.     """
  9.     A viewset that provides default create(), retrieve(), update(), partial_update(), destroy(), andlist() actions.
  10.     """
  11.     pass

示例代码

  1. from api.utils.serializsers.pager import PagerSerialiser 
  2. from rest_framework.viewsets import ModelViewSet
  3. from rest_framework.mixins import ListModelMixin, CreateModelMixin
  5. class ViewlView(ModelViewSet)：
  6.     queryset=models.Role.objects.al1()
  7.     serializer_class=PagerSerialiser 
  8.     pagination_class=PageNumberPagination 
  12. # urls.py
  13. url(r"^(?P[vl|v2]+)/v1/$",views.ViewlView.as_view(
  14.                                         {"get"："list","post"："create"})),
  15. ur1(x"^(?P[vl|v2]+)/v1/(?P\d+)/$",views.ViewlView.as_view( {"get"："retrieve","delete"："destroy","put"："update","patch"："partial_update"})),

总结：

  1. 简单的增删改查；可以使用ModelViewSet
  2. 增删；可以使用CreateModelMixin,DestroyModelMixin,GenericAPIViewSet
  3. 复杂逻辑 APIView/GenericAPIView
