一、自定義路由（原始方式）

1. 路由層

urlpatterns = [url(r'^admin/', admin.site.urls),url(r'^publish/$', views.PublishView.as_view()),url(r'^publish/(?P<pk>\d+)', views.PublishDetailView.as_view()),]

• 注意點(diǎn)：注意路由的寫(xiě)法，一定注意加上$結(jié)尾
  

2. 序列化生成器

class PublishSerializer(serializers.ModelSerializer):class Meta:model = models.Publishfields = "__all__"

3. 視圖層

# 所有對(duì)象 class PublishView(APIView):def get(self, request):publish_list = models.Publish.objects.all()publish_ser = PublishSerializer(instance=publish_list, many=True)return Response(publish_ser.data)# 單個(gè)對(duì)象 class PublishDetailView(APIView):def get(self, request, pk):publish_obj = models.Publish.objects.filter(pk=pk).first()publish_ser = PublishSerializer(publish_obj, many=False)return Response(publish_ser.data)

二、繼承ModelViewSet（半自動(dòng)）

1. 路由層：

url(r'^publish/$', views.PublishView.as_view({'get':'list','post':'create'})), url(r'^publish/(?P<pk>\d+)$', views.PublishView.as_view({'get':'retrieve','delete':'destroy','put':'update'})),

2. 視圖層：

from rest_framework.viewsets import ModelViewSetclass PublishView(ModelViewSet):queryset = models.Publish.objects.all()serializer_class = PublishSerializer

?

三、自動(dòng)生成路由

1. 路由層

from rest_framework.routers import DefaultRouter, SimpleRouter# 自動(dòng)生成四條路由 router = DefaultRouter() # 自動(dòng)生成兩條路由 # router = SimpleRouter()

# 需要傳兩個(gè)參數(shù),第一個(gè)參數(shù)就是匹配的路徑,第二個(gè)參數(shù),是視圖類(lèi)
router.register('publish', views.PublishView)

urlpatterns = [
??? url(r'^admin/', admin.site.urls),

??? url(r'', include(router.urls))

]

四條路由

兩條路由：

?

?

2. 視圖層

from rest_framework.viewsets import ModelViewSetclass PublishView(ModelViewSet):queryset = models.Publish.objects.all()serializer_class = PublishSerializer

總結(jié)：

-url控制-基本路由寫(xiě)法：咱們一直寫(xiě)的-第二種寫(xiě)法（必須繼承只要繼承了ViewSetMixin）：# url(r'^publish/$', views.PublishView.as_view({'get':'list','post':'create'})),# url(r'^publish\.(?P<format>\w+)$', views.PublishView.as_view({'get':'list','post':'create'})),# url(r'^publish/(?P<pk>\d+)$', views.PublishView.as_view({'get':'retrieve','delete':'destroy','put':'update'})),-第三種（自動(dòng)生成路由，必須繼承ModelViewSet）：-SimpleRouter 自動(dòng)生成兩條路由from rest_framework.routers import SimpleRouter,DefaultRouterrouter=SimpleRouter()router.register('publish',views.PublishView)、、、、url(r'', include(router.urls)),-DefaultRouter自動(dòng)生成四條路由from rest_framework.routers import SimpleRouter,DefaultRouterrouter=DefaultRouter()router.register('publish',views.PublishView)、、、、url(r'', include(router.urls)),
