Question

我坚持这个烦人的问题，如果有人能提出一些实际有用的建议，我将不胜感激。我已经在StackOverflow中搜索了类似的问题，并意识到所提出的解决方案都不适用于我。我在Python和Django更新之后开始收到此错误（在更新之前一切正常）。现在，当我尝试打开登录页面时，我看到了这个例外：

NoReverseMatch at /accounts/login/

这些是我的项目设置：

INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'home',
'django.contrib.sites',
'allauth',
'allauth.account',
'allauth.socialaccount',
'allauth.socialaccount.providers.facebook',
'appointment',
'staff',
'job',
'news',
'articles',)


MIDDLEWARE_CLASSES = (

'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',)

TEMPLATE_PATH = os.path.join(BASE_DIR, 'templates')

TEMPLATE_DIRS = ( 
TEMPLATE_PATH,)

TEMPLATE_CONTEXT_PROCESSORS = (
"django.contrib.auth.context_processors.auth",
"django.core.context_processors.debug",

"django.contrib.messages.context_processors.messages",
"django.core.context_processors.request",    
"allauth.account.context_processors.account",
"allauth.socialaccount.context_processors.socialaccount",)

AUTHENTICATION_BACKENDS = (
# Needed to login by username in Django admin, regardless of `allauth`
"django.contrib.auth.backends.ModelBackend",
# `allauth` specific authentication methods, such as login by e-mail
"allauth.account.auth_backends.AuthenticationBackend")

SOCIALACCOUNT_QUERY_EMAIL = True
SOCIALACCOUNT_PROVIDERS = {
'facebook': {
    'SCOPE': ['email', 'publish_stream'],
    'METHOD': 'js_sdk'  }}

SITE_ID=7

这是引发异常的模板：

In template D:\Django\dentstudio\templates\socialaccount\snippets\login_extra.html, error at line 3

1   {% load socialaccount %}
2   
3   {% providers_media_js %}

我的urls.py:

from django.conf.urls import patterns, include, url
from django.contrib import admin
from home import views
from django.conf import settings

urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
url(r'^home/', include('home.urls')),
url(r'^appointment/', include('appointment.urls')),
url(r'^people/', include('staff.urls')),
url(r'^admin/', include(admin.site.urls)),
url(r'^inside/', views.inside, name='inside'),
url(r'^chat/', views.chat, name='chat'),

url(r'^prices/', views.prices, name='prices'),
url(r'^services/', views.services, name='services'),
url(r'^contacts/', views.contacts, name='contacts'),
url(r'^articles/', include('articles.urls')),

）

if settings.DEBUG:
  urlpatterns += patterns(
    'django.views.static',
    (r'^media/(?P<path>.*)',
    'serve',
    {'document_root': settings.MEDIA_ROOT}), )

我的allauth urls.py：

from django.conf.urls import url, patterns, include
from home import views

try:
import importlib
except ImportError:
from django.utils import importlib

from allauth.socialaccount import providers

from . import app_settings

urlpatterns = patterns('', url('^', include('allauth.account.urls')),     url(r'^profile/', views.profile, name='profile'),)

if app_settings.SOCIALACCOUNT_ENABLED:
urlpatterns += patterns('', url('^social/',
                                include('allauth.socialaccount.urls')))

for provider in providers.registry.get_list():
try:
    prov_mod = importlib.import_module(provider.package + '.urls')
except ImportError:
    continue
prov_urlpatterns = getattr(prov_mod, 'urlpatterns', None)
if prov_urlpatterns:
    urlpatterns += prov_urlpatterns

我已经在考虑为facebook授权安装另一个应用程序，因为只能处理这个令人愤怒的异常。请帮帮忙，谢谢！

我和你有同样的问题。经过一些激烈的调试后，似乎在我的制作环境中我没有安装请求。当导入urls.py时（在views.py中导入），此包用于每个allauth.socialaccount.providers。*。

我必须提一下，当我进行GET和/ accounts /我的facebook网址不存在时。

所以你已经对此有了解释。

https://docs.djangoproject.com/en/dev/ref/urlresolvers/#django.core.urlresolvers.reverse

“作为计算哪些URL名称映射到哪些模式的一部分，reverse（）函数必须导入所有URLconf文件并检查每个视图的名称。这涉及导入每个视图函数。如果有任何错误在导入任何视图函数时，它会导致reverse（）引发错误，即使该视图函数不是您要反转的函数。

确保您在URLconf文件中引用的任何视图都存在，并且可以正确导入。不要包含引用您尚未编写的视图的行，因为这些视图不可导入。“

解决方案是安装请求包：pip install requests

主要思想在于上述文档说明。如果您收到该错误，则当您访问/ accounts /（在调试模式下）时，您可能无法看到错误的链接。因此，请尝试为您的应用调试urls.py。

使用django shell非常有效。
