Question

我在网站的主页上收到此错误：

的NoReverseMatch

使用参数'（）'和找不到关键字参数'{}来反转'admin'。尝试了0种模式：[]。

这是我的urls.py:

from django.conf.urls import url
from django.contrib import admin
from rest_framework.urlpatterns import format_suffix_patterns
from rest_framework import routers
from . import views

router = routers.SimpleRouter()
router.register(r'queue', views.QueueItemViewSet)
router.register(r'label', views.EventLabelViewSet)
urlpatterns = router.urls

urlpatterns += [
    url(r'^$', views.api_root),
    url(r'^fingerprint/submit/$', views.FingerprintSubmit.as_view(),
        name="fingerprint-submit"),
    url(r'^fingerprint/rebuild/$', views.RebuildFingerprints.as_view(),
        name="fingerprint-rebuild"),
    url(r'^admin/', admin.site.urls, name="admin"),
]

urlpatterns = format_suffix_patterns(urlpatterns)

这是令人讨厌的views.py片段：

@api_view(['GET'])
def api_root(request, format=None):
    """
    Home page of the API
    """
    return Response({
        'admin': reverse('admin', request=request, format=format)})

最后，追溯：

我查看了其他帖子，但没有发现任何有用的信息，我刚加入这个项目，所以我不知道原来程序员在这里尝试做什么。

Answer 1

admin.site.urls不是视图，它是URL配置文件，其URL名称空间为admin。它有点不同，因为你不应该使用include()，但是在其他方面它就像包含不同的URLconf一样。

由于它是一个包含，name参数绝对没有效果。

要反转管理员的主页面，请使用：

return Response({
    'admin': reverse('admin:index', request=request, format=format),
})

可以找到管理员网址的完整列表in the docs。

NoReverseMatch at /
