一:自定义路由(原始方式)
from django.conf.urls import url
from app01 import views
urlpatterns = [
url(r'^books/$', views.BookView.as_view()),
url(r'^books/(?P<pk>d+)$', views.BookDetailView.as_view()),
]
class BookView(APIView):
def get(self, request):
book_list = models.Book.objects.all()
bs = BookSerializers(book_list, many=True)
return Response(bs.data)
def post(self, request):
# 添加一条数据
print(request.data)
bs=BookSerializers(data=request.data)
if bs.is_valid():
bs.save() # 生成记录
return Response(bs.data)
else:
return Response(bs.errors)
class BookDetailView(APIView):
def get(self,request,pk):
book_obj=models.Book.objects.filter(pk=pk).first()
bs=BookSerializers(book_obj,many=False)
return Response(bs.data)
def put(self,request,pk):
book_obj = models.Book.objects.filter(pk=pk).first()
bs=BookSerializers(data=request.data,instance=book_obj)
if bs.is_valid():
bs.save() # update
return Response(bs.data)
else:
return Response(bs.errors)
def delete(self,request,pk):
models.Book.objects.filter(pk=pk).delete()
return Response("")
二 半自动路由(视图类继承ModelViewSet)
from django.conf.urls import url
from app01 import views
urlpatterns = [
url(r'^publish/$', views.PublishView.as_view({'get':'list','post':'create'})),
url(r'^publish/(?P<pk>d+)/$', views.PublishView.as_view({'get':'retrieve','put':'update','delete':'destroy'})),
]
from rest_framework.viewsets import ModelViewSet
class PublishView(ModelViewSet):
queryset=models.Publish.objects.all()
serializer_class=PublishSerializers
三 全自动路由(自动生成路由)
from django.conf.urls import url,include
from app01 import views
from rest_framework import routers
router=routers.DefaultRouter()
# 两个参数,一个是匹配的路由,一个是视图中写的CBV的类
router.register('publish',views.PublishView)
urlpatterns = [
# http://127.0.0.1:8000/publish/format=json(渲染器通过这个判断,返回渲染的页面)
# url(r'^publish/', views.PublishView.as_view({'get':'list','post':'create'})),
# http://127.0.0.1:8000/publish.json(渲染器通过这个判断,返回渲染的页面)
# url(r'^publish.(?P<format>w+)$', views.PublishView.as_view({'get':'list','post':'create'})),
# 可以用 以下方式访问
# 1 http://127.0.0.1:8000/publish/
# 2 http://127.0.0.1:8000/publish.json
# 3 http://127.0.0.1:8000/publish/3
# 4 http://127.0.0.1:8000/publish/3.json
url(r'',include(router.urls))
]
from rest_framework.viewsets import ModelViewSet
class PublishView(ModelViewSet):
queryset=models.Publish.objects.all()
serializer_class=PublishSerializers
