Question

我使用django rest framework有以下代码。

urls.py

urlpatterns = [
    url(r'^portfolio1/', include('portfolio1.urls')),
    url(r'^admin/', admin.site.urls),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))]

portfolio1 / urls.py

app_name = 'portfolio1'
urlpatterns = [
    url(r'^$', \
            views.api_root),
    url(r'^users/$', \
            views.UserList.as_view(), \
            name='user-list'),
    url(r'^users/(?P<pk>[-\d]+)/$', \
            views.UserDetail.as_view(), \
            name='user-detail'),
]
urlpatterns = format_suffix_patterns(urlpatterns)

portfolio1 / serializers.py

from django.contrib.auth.models import User as AuthUser
class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = AuthUser
        fields = ('id', 'username', 'url')

portfolio1 / views.py

from django.contrib.auth.models import User as AuthUser
class UserList(generics.ListAPIView):
    queryset = AuthUser.objects.all()
    serializer_class = UserSerializer

class UserDetail(generics.RetrieveAPIView):
    queryset = AuthUser.objects.all()
    serializer_class = UserSerializer

@api_view(('GET',))
@permission_classes((permissions.AllowAny, ))
def api_root(request, format=None):
    return Response({
        'users': reverse('user-list', request=request, format=format)
    })

我收到以下错误。

NotperlyConfigured：无法使用视图名称“user-detail”解析超链接关系的URL。您可能未能在API中包含相关模型，或者在此字段上错误地配置了lookup_field属性。

我知道这个错误意味着什么，但不知道为什么我会得到它。是否必须对django rest framework（https://github.com/tomchristie/django-rest-framework/issues/2711）的版本进行任何操作？我已经确保我没有犯下与HyperlinkedIdentityField returning error only on User model相同的错误。

删除function groupStrings($input) { $dict = \array_reduce($input, function(array $out, $in) { //retrieve the unique characters of each word $key = \array_unique(\str_split($in)); //sort alphabetically A-Z (ignores case) \natcasesort($key); //create an associative index from the key $key = \implode('', $key); if(!\array_key_exists($key, $out)) { $out[$key] = []; } $out[$key][] = $in; return $out; }, []); return \implode(',', \array_map(function($word) { return \implode(',', $word); }, $dict)); } $input = ['student', 'students', 'dog', 'studentssess', 'god', 'cat']; echo groupStrings($input);中的app_name = 'portfolio1'。

HyperlinkedModelSerializer在django rest框架中使用auth.User抛出了ImproperlyConfigured错误
