编辑: 凯文在下面的回答解决了我的问题。结果是“allauth 不支持 namespace ”，所以我不应该将它引入我的 urls.py
原帖:
我已经完全按照教程安装了 django-allauth https://github.com/pennersr/django-allauth
我这里有一个非常基本的问题；即使在我添加社交整合之前，也无法使基本用户登录/退出页面正常工作。
通过导航到/admin，我点击了“注销”，所以我不是登录用户。
现在当我访问 /accounts/login 时遇到这个错误
NoReverseMatch at /accounts/login/
Reverse for 'account_signup' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []
Request Method: GET
Request URL: http://localhost:5000/accounts/login/
Django Version: 1.6.5
Exception Type: NoReverseMatch
Exception Value:
Reverse for 'account_signup' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []
问题:是否需要修改默认的allauth views.py来解决这个问题？
在相关情况下，当我尝试通过 shell 时，这是同样的问题
(awe01)MoriartyMacBookAir13:getstartapp macuser$ python manage.py shell
Python 2.7.5 (default, Mar 9 2014, 22:15:05)
>>> from django.core.urlresolvers import reverse

过去一个小时一直在谷歌搜索，我没有看到我遗漏了什么。它应该开箱即用，对吧？ 我看到默认的 base.html 似乎已经有了这行，{% load url from future %}
为了确认，这里有一些来 self 的主要 settings.py 的摘录(在文件夹 shareducate/settings.py 中)

我修改了shareducate/urls.py url(r'^accounts/', include('allauth.urls', namespace='allauth')), 但我没有修改 allauth 文件夹中的任何内容
注意:通过转到/admin，我可以以 super 用户身份登录。然后果然，访问/accounts/login 将我重定向到 root/，根据 settings.py 如果我注释掉该行，# LOGIN_REDIRECT_URL = '/' 那么我肯定会根据 http://被定向到 /accounts/profile/ stackoverflow.com/a/16956071/870121
现在我已经注销了(这是我通过/admin 界面实现的)，当我访问 /accounts/login 时，allauth 程序似乎无法处理我/p>
注意/allauth/templates/account/login.html 看起来像这样......我根本没有编辑它
{% extends "account/base.html" %}
{% load i18n %}
{% load account %}
{% load url from future %}
{% block head_title %}{% trans "Sign In" %}{% endblock %}
{% block content %}
<h1>{% trans "Sign In" %}</h1>
{% if socialaccount.providers %}
<p>{% blocktrans with site.name as site_name %}Please sign in with one

基于这个答案http://stackoverflow.com/a/13202435/870121 我想我可能需要修改这个 allauth/accounts/views.py 中的第 109 行
84 class LoginView(RedirectAuthenticatedUserMixin,
85 AjaxCapableProcessFormViewMixin,
86 FormView):
87 form_class = LoginForm
88 template_name = "account/login.html"
89 success_url = None
90 redirect_field_name = "next"
91
92 def get_form_class(self):
93 return get_form_class(app_settings.FORMS, 'login', self.form_class)
94
95 def form_valid(self, form):
96 success_url = self.get_success_url()
97 return form.login(self.request, redirect_url=success_url)
98
99 def get_success_url(self):
100 # Explicitly passed ?next= URL takes precedence
101 ret = (get_next_redirect_url(self.request,
102 self.redirect_field_name)
103 or self.success_url)
104 return ret
105
106 def get_context_data(self, **kwargs):
107 ret = super(LoginView, self).get_context_data(**kwargs)
108 signup_url = passthrough_next_redirect_url(self.request,
109 reverse("account_signup"),
110 self.redirect_field_name)
111 redirect_field_value = self.request.REQUEST \
112 .get(self.redirect_field_name)
113 ret.update({"signup_url": signup_url,
114 "site": Site.objects.get_current(),
115 "redirect_field_name": self.redirect_field_name,
116 "redirect_field_value": redirect_field_value})
117 return ret
118
119 login = LoginView.as_view()
你看到它有 reverse("account_signup") 没有额外的参数 我没有对此进行编辑，因为我认为 allauth 应该开箱即用，并且我不愿意通过修补来破坏事物
该行在完整的回溯错误中突出显示。 回溯:

(2) SITE_ID 对此很重要，还是仅对社交融合很重要？
请告知从此处可能有意义的故障排除步骤。提前致谢，M
请您参考如下方法:
让我用一些调试技巧来展示这个答案，希望这些技巧在将来会被证明是有用的。
当您看到特定的 Django 错误时，几乎总是意味着您的 urls.py 有问题。如此广泛使用的软件包存在影响此类基本用法的错误的可能性很小，因此在这种情况下挖掘源代码可能是浪费精力。
您说您“完全按照教程”安装了 django-allauth，但是当我将您的设置与 documentation 进行比较时我看到了这个区别:
文档:(r'^accounts/', include('allauth.urls'))
你:(r'^accounts/', include('allauth.urls', namespace='allauth'))
看来您对命名空间的使用有问题。
快速 Google search拉起 this issue ，其中包作者解释说不支持命名空间。
因此，如果您去掉 namespace 参数，一切都应该按预期工作。
