AI-视图组件-五个接口的最终简化版-优快云博客

本文详细解析了使用Django Rest Framework（DRF）中ModelViewSet封装五个基本CRUD操作接口的方法，包括如何定义URL路由、序列化器及视图集，通过具体代码示例展示了接口的实现过程。

五个接口最终版

#url.py
# 序列化最贱版本
    url(r'^customer/$', views.CustomerView.as_view({"get":"list","post":"create"})),
    url(r'^customer/(?P<pk>\d+)', views.CustomerView.as_view({"get":"retrieve","put":"update","delete":"destroy"})),

views.py
from rest_framework.serializers import ModelSerializer
class CustomerSerializer(serializers.ModelSerializer):
    class Meta:
        model=Customer
        # field=["name","gender"]
        fields="__all__"

from rest_framework.viewsets import ModelViewSet
class CustomerView(ModelViewSet): #将五个数据接口全部封装在了ModelViewSet
    queryset = Customer.objects.all()
    serializer_class = CustomerSerializer

五个接口最终版源码解析

#url(r'^authors/(?P<pk>\d+)/', views.AuthorsView.as_view({"get":"retrieve","delete":"destroy","put":"update"})),
            #url(r'^authors/$', ViewSetMixin.as_view({"get":"retrieve","delete":"destroy","put":"update"})),
            #url(r'^authors/$', ViewSetMixin.view),
            一旦用户访问,get访问authors/1：
            ViewSetMixin.view(reqeust):
                         for method, action in actions.items(): # {"get":"retrieve","delete":"destroy","put":"update"}
                                handler = getattr(self, action) #  handler===self.retrieve    handler=== destroy    handler===update
                                setattr(self, method, handler)  #  self.get=self.retrieve    self.delete=self.destroy   self.put=self.update

                         return self.dispatch(request, *args, **kwargs)    
                         #
                         APIView.dispatch(request):
                                                 
                                                  handler = getattr(self, request.method.lower()) # self.retrieve
                                                  response = handler(request, *args, **kwargs)    
                                                  #     def retrieve(self.request):
           `                                      #            return .....
                                                            
                                                  return response
