DRF框架之视图方法的几个封装好的模块介绍(第三天)

时间：2021-06-27 20:43:14

1.DRF框架给我们封装好了好多层模块的 来实现简便接口的编写

# from rest_framework.mixins import CreateModelMixin, UpdateModelMixin, RetrieveModelMixin, ListModelMixin, \

#     DestroyModelMixin

# from rest_framework.generics import GenericAPIView

#

    #这里是加载drf框架的mixins 模块的功能

    #ListModelMixin         是给get 获取多本书接口使用

    #CreateModelMixin       是给post接口用的

    #UpdateModelMixin       是给put 接口使用的

    #RetrieveModelMixin     是给get 单本书的接口使用的

    #DestroyModelMixin      是给delete 接口使用的

    #GenericAPIView         注意!!!!使用mixins模块一定也要加载这个模块,不然无法通过django的验证功能

#

# class Booksview(CreateModelMixin, ListModelMixin, GenericAPIView):

#     serializer_class = BookSerializers        #使用序列化功能,之前写好的显示的内容

#     queryset = models.Book.objects.all()      #对数据库的那个表进行操纵使用

#

#     def post(self, request, *args, **kwargs):

#         return self.create(request, *args, **kwargs)      #post的接口

#

#     def get(self, request, *args, **kwargs):

#         return self.list(request, *args, **kwargs)        #get所有数据的接口

#

#

# class Bookview(RetrieveModelMixin, UpdateModelMixin, DestroyModelMixin,GenericAPIView):

#     serializer_class = BookSerializers

#     queryset = models.Book.objects.all()

#

#     def put(self, request, *args, **kwargs):              #put接口 修改内容

#         return self.update(request, *args, **kwargs)

#

#     def get(self, request, *args, **kwargs):              #get单个信息的接口

#         return self.retrieve(request, *args, **kwargs)

#

#     def delete(self, request, *args, **kwargs):           #delete 接口删除用的

#         return self.destroy(request, *args, **kwargs)

通过mixin组件实现

2. 更简便的方法来实现五种请求方式

#第三层：使用generics 下ListCreateAPIView,RetrieveUpdateDestroyAPIView

# from rest_framework.generics import ListAPIView,ListCreateAPIView,RetrieveUpdateDestroyAPIView,DestroyAPIView,CreateAPIView

# #它有两个接口，一个是获取所有，一个是新增

# class BooksView(ListCreateAPIView):

#     serializer_class=BookSerializer

#     queryset=models.Book.objects.all()

#

# class BookView(RetrieveUpdateDestroyAPIView):

#     serializer_class=BookSerializer

#     queryset=models.Book.objects.all()

ListCreateAPIView,RetrieveUpdateDestroyAPIView

3. 最终使用的也是最难的,灵活度最高的

#最终，一般用的时候，会经常用ViewSetMixin

#ViewSetMixin干了什么事？重写了as_view方法

# from rest_framework.viewsets import ViewSetMixin

# class Publish(ViewSetMixin,APIView):

#

#     def aa(self,request):

#         return HttpResponse('aa')

#     def bb(self,request):

#         return HttpResponse('aa')

#     def cc(self,request):

#         return HttpResponse('aa')

#     def dd(self,request):

#         return HttpResponse('aa')

#     def get_all(self,request):

#         pass

#     def get_one(self,request):

#         pass

#     def create(self,request):

#         pass

#     def create_by_id(self,request):

#         pass
from django.conf.urls import url

from django.contrib import admin

from app01 import views

urlpatterns = [

    url(r'^admin/', admin.site.urls),

    # url(r'^books/$', views.BooksView.as_view()),

    # url(r'^books/(?P<pk>\d+)', views.BookView.as_view()),

    # url(r'^test', views.Publish.as_view({'get':'aa'})),

    # url(r'^xx', views.Publish.as_view({'post':'cc'})),
