最近对产品api进行rest改造完毕，就记录下Django中rest-framework的一些基本用法
rest_framework使用
- 显示api入口
from rest_framework.decorators import api_view
from rest_framework.reverse import reverse
@api_view(['GET'])
def api_root(request, format=None):
return Response({'users': reverse('user-list', request=request, format=format),
'snippets': reverse('snippet-list', request=request, format=format)})
url(r'^$',api_root),
url(r'^xuliehua/$',hellolist.as_view(),name='snippet-list'),
url(r'^users/$', UserList.as_view(),name='user-list'),
- 利用html显示实例的某个属性
from rest_framework import renderers
class SnippetHighlight(generics.GenericAPIView):
queryset = Snippet.objects.all()
renderer_classes = (renderers.StaticHTMLRenderer,) #使用html静态页面来渲染
def get(self, request, *args, **kwargs):
snippet = self.get_object()
return Response(''+snippet.title+'')
url(r'^hello/(?P\d+)/highlight/$',SnippetHighlight.as_view()),
* 超链接显示属性or详情
class SuserSerializer(serializers.ModelSerializer):
snippet = serializers.HyperlinkedRelatedField(many= True,read_only=True,view_name='snippet-detail')
class Meta:
model=Suser
fields=('name','ok','snippet')
class SnippetSerializer(serializers.ModelSerializer):
title=serializers.HyperlinkedIdentityField(view_name='snippet-highlight',format='html')
class Meta:
model = Snippet
fields = ('id', 'title', 'code')
* 使用viewsets
class UserViewSet(viewsets.ReadOnlyModelViewSet):
queryset = Suser.objects.all()
serializer_class = SuserSerializer
class SnippetViewSet(viewsets.ModelViewSet):
queryset = Snippet.objects.all()
serializer_class = SnippetSerializer
permission_classes = (permissions.IsAuthenticatedOrReadOnly,)
@detail_route(renderer_classes=[renderers.StaticHTMLRenderer])
def highlight(self, request, *args, **kwargs):
snippet = self.get_object()
return Response(snippet.title)
snippet_list = SnippetViewSet.as_view({
'get': 'list',
'post': 'create'
})
snippet_detail = SnippetViewSet.as_view({
'get': 'retrieve',
'put': 'update',
'delete': 'destroy'
})
snippet_highlight = SnippetViewSet.as_view({
'get': 'highlight'
}, renderer_classes=[renderers.StaticHTMLRenderer])
user_list = UserViewSet.as_view({
'get': 'list'
})
user_detail = UserViewSet.as_view({
'get': 'retrieve'
})
url(r'^xuliehua/$',snippet_list,name='snippet-list'),
url(r'^hello/(?P\d+)/$',snippet_detail,name='snippet-detail'),
url(r'^hello/(?P\d+)/highlight/$',snippet_highlight,name='snippet-highlight'),
url(r'^users/$', user_list,name='user-list'),
url(r'^users/(?P[0-9]+)/$', user_detail,name='suser-detail'),
