Django 1.11.3 Serializers.py from rest_framework import serializers from .models import Goods,GoodsCategory class GoodCategorySerializer(serializers.ModelSeliazer): class Meta: models=GoodCategory field="__all__" //field=["id","name"] class GoodsSerializer(serializers.ModelSerializer): category=GoodCategorySeriazlize() //(many=True),部分重定义,会显示详细内容 class Meta: models=Goods field="__all__" views from rest_framework.views import APIView from rest_framework import generics from rest_framework.response import Response from rest_framework import viewsets from rest_framework.viewsets import mixins GenericViewset(Viewset) -drf GenericAPIView -drf APIView -drf View -django
mixin
1.listModelMixin
//帮助做过滤、分页、序列化
2.createModelMixin
//创建视图扩展类,提供create(request, *args, **kwargs)
方法快速实现创建资源的视图,成功返回201状态码。
class CreateModelMixin(object): """ Create a model instance. """ def create(self, request, *args, **kwargs): # 获取序列化器 serializer = self.get_serializer(data=request.data) # 验证 serializer.is_valid(raise_exception=True) # 保存 self.perform_create(serializer) headers = self.get_success_headers(serializer.data) return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers) def perform_create(self, serializer): serializer.save() def get_success_headers(self, data): try: return {‘Location‘: str(data[api_settings.URL_FIELD_NAME])} except (TypeError, KeyError): return {} ————————————————
3.updateModelMixin
4.destroyModelMixin
5.retrieveModelMixin
6.各种组合
url.py from rest_framework import DefaultRouter router=DefaultRouter() router.register(r‘goods‘,GoodListViewset,base_name="goods") //配置Goods的url router.register(.....) urlpatterns=[ url(r‘^‘,include(router.urls)), ] eg: 1. APIView - ModelSerialzer url(r‘^news/agree/$‘,article.NewAgreeView.as_view()) url(r‘^news/collect/(?P<pk>d+)/$‘,article.Collect.as_view()) class NewAgreeView(APIView) def post(self,request,*args,**kwargs): .... class NewAgreeView(APIView) def post(self,request,*args,**kwargs): nid=kwargs.get("pk") 2. url(r‘^news/$‘,article.Article.as_view({‘get‘:‘list})), url(r‘^news/(?P<pk>/d+)/$,article.Article.as_view({‘get‘:‘retrieve‘})) class ArticleView(ViewSetMixin, APIView): def list(self,request,*args,**kwargs): ... def retrieve(self,request,*args,**kwargs): ...
