u'rest_framework'不是注册的命名空间

Question

我正在尝试使用Django Rest Framework进行身份验证,但我无法通过DRF面板登录.当我尝试通过指定到达登录页面时

/ API/API-AUTH /登录/

NoReverseMatch at /api/api-auth/login/

urls.py

urlpatterns = patterns(
    '',
    url(r'^api/', include('api.urls', namespace='api')),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^oauth2/', include('oauth2_provider.urls',
                             namespace='oauth2_provider'))
)

API/urls.py:

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

我该怎么办？

Answer 1

问题出在你的命名空间上.具体来说,您使用的是嵌套命名空间,而Django REST框架并不期望这样.

登录可浏览API的教程建议使用以下API网址代码段

# The API URLs are now determined automatically by the router.
# Additionally, we include the login URLs for the browsable API.
urlpatterns = [
    url(r'^', include(router.urls)),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]

因此,您的登录URL将位于/api-auth/并具有命名空间rest_framework,因此不会干扰现有的URL模式.本教程假设您在放置模式时位于根urlconf中,或者至少您没有使用额外的命名空间.这是因为url rest_framework:login用于生成可浏览API的登录页面,因此名称空间必须是rest_framework.

在您的情况下,您正在注册URL api,因此视图名称实际上是api:rest_framework:login.你得到的错误

u'rest_framework'不是注册的命名空间

是因为rest_framework命名空间不是根命名空间.您可以通过将urlpattern移到外部api/urls.py或覆盖可浏览的API模板来解决此问题.

尝试添加行url(r'^api-auth/', include('rest_framework.urls',namespace='rest_framework')),你的主urls.py或改变namespace的api/,以rest_framework代替(和其他URL删除)...
