rest_framework笔记: 使用url无法获取到url的地址

我遇到的问题,和这个外国人问题一样,因为app有名字,导致restframework使用HyperlinkedModelSerializer ,里面的url不成功。

他的地址是:https://stackoverflow.com/questions/18231887/model-field-named-url-and-django-rest-framework-url

My serializers.py file:


classSnippetSerializer(serializers.HyperlinkedModelSerializer):

owner=serializers.ReadOnlyField(source='owner.username')

highlight=serializers.HyperlinkedIdentityField(view_name='snip:snippet-highlight', format='html')

#url = serializers.SerializerMethodField('get_snippet_url')

#url=serializers.HyperlinkedIdentityField(view_name='snip:snippet-detail')

classMeta:

model=Snippet

fields=('url','title','code','linenos','language','style','owner','highlight')

# def get_snippet_url(self, obj):

#    # generate the url for the key

#    url = reverse('snip:snippet-detail')

我的项目根url:

url(r'^snip/', include('snippets.urls', namespace='snip'))


我的app的url:

urlpatterns=format_suffix_patterns([

url(r'^$',api_root),

url(r'^snippets/$',SnippetList.as_view(), name='snippet-list'),

url(r'^snippets/(?P[0-9]+)/$',SnippetDetail.as_view(),name='snippet-detail'),

url(r'^snippets/(?P[0-9]+)/highlight/$',SnippetHighlight.as_view(),name='snippet-highlight'),

url(r'^users/$', UserList.as_view(),name='user-list'),

url(r'^users/(?P[0-9]+)/$', UserDetail.as_view(),name='user-detail'),

])

这样每次,都是告诉我无法找到snippet-detail.

解决办法:


url=serializers.HyperlinkedIdentityField(view_name='snip:snippet-detail')


笔记:

如果我们创建了一个基于超链接的API,我们需要确保每个URL都被命名了。让我们看看那些需要被命名的URL:

1.根URL包含'user-list'和'snippet-list'

2.snippet serializer包含指向'snippet-highlight'的字段

3.user serializer包含指向'snippet-detail'的字段

4. snippet serializers和user serializers 包含'url'字段,这个字段默认指向'{model_name}-detail',这里分别是'snippet-detail'和'user-detail'
