django-allauth返回錯誤“反向…，未找到參數'（）'和關鍵字參數'{}'”

Question

編輯：凱文下面的答案解決了我的問題。 原來是“ allauth不支持名稱空間”，所以我不應該在urls.py中引入它。

原始帖子：

我已經完全按照教程https://github.com/pennersr/django-allauth安裝了django-allauth

我這里有一個非常基本的問題； 甚至在我加入社交集成之前，基本用戶登錄/退出頁面都無法正常工作。

通過導航到/ admin，我單擊了“注銷”，因此我不是登錄用戶。

現在，當我訪問/accounts/login我會遇到此錯誤

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: []

問題：我是否需要修改默認的allauth views.py才能解決此問題？

如果相關，當我通過外殼嘗試時，這是相同的問題

在過去一個小時的搜索中，我看不到我所缺少的東西。 應該開箱即用，對吧？ 我看到默認的base.html似乎已經有了這一行， {% load url from future %}

確認一下，以下是我的主要settings.py的摘錄（在shareducate / settings.py文件夾中）

我已經修改了shareducate / urls.py url(r'^accounts/', include('allauth.urls', namespace='allauth')),但是我還沒有修改allauth文件夾中的任何內容

注意：通過轉到/ admin，我可以以超級用戶身份登錄。 然后足夠確定，根據settings.py ，訪問/ accounts / login將我重定向到root /，如果我注釋掉該行， # LOGIN_REDIRECT_URL = '/'那么就足夠確定我將按照http://stackoverflow.com/a/16956071/870121定向到/accounts/profile/ http://stackoverflow.com/a/16956071/870121

現在，盡管我已經注銷（這是通過/ admin界面實現的），但是當我訪問/accounts/login時，allauth程序似乎無法處理我

注意/allauth/templates/account/login.html看起來像這樣...我根本沒有編輯它

{% 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
of your existing third party accounts. Or, <a href="{{ signup_url }}">sign up</a>

</div>

{% include "socialaccount/snippets/login_extra.html" %}

{% else %}
<p>{% blocktrans %}If you have not created an account yet, then please
<a href="{{ signup_url }}">sign up</a> first.{% endblocktrans %}</p>
{% endif %}

<form class="login" method="POST" action="{% url 'account_login' %}">
  {% csrf_token %}

  <input type="hidden" name="{{ redirect_field_name }}" value="{{ redirect_field_value }}" />
  {% endif %}
  <a class="button secondaryAction" href="{% url 'account_reset_password' %}">{% trans "Forgot Password?" %}</a>
  <button class="primaryAction" type="submit">{% trans "Sign In" %}</button>
</form>

{% endblock %}

猜測

（1）

基於此答案http://stackoverflow.com/a/13202435/870121我認為我可能必須在allauth / accounts / views.py中修改第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()

您會看到它具有reverse("account_signup") ，沒有多余的參數，我沒有編輯此參數，因為我認為allauth應該可以直接使用，並且願意通過修補來破壞事物

該行在完整的追溯錯誤中突出顯示。 追溯：

File "/Users/macuser/Dropbox/code/heroku/awe01/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response
  112.                     response = wrapped_callback(request, *callback_args, **callback_kwargs)

  452.                              (lookup_view_s, args, kwargs, len(patterns), patterns))

（2）SITE_ID對此很重要，還是僅對社會融合而言重要？

請告知從此處開始有意義的故障排除步驟。 預先感謝，M

Answer 1

讓我用一些調試技巧來給出這個答案，希望這些技巧在將來會很有用。

當您看到該特定的Django錯誤時，幾乎總是意味着您的urls.py 。 如此廣泛使用的軟件包具有影響這種基本用法的錯誤的可能性很小，因此在這種情況下，深入研究源代碼可能是浪費的精力。

您說您“完全按照教程”安裝了django-allauth ，但是當我將設置與文檔進行比較時，我看到了這種差異：

文檔： (r'^accounts/', include('allauth.urls'))

您： (r'^accounts/', include('allauth.urls', namespace='allauth'))

因此，您使用命名空間似乎出現了問題。

快速的Google搜索可以解決此問題 ，包作者在其中說明不支持命名空間。

因此，如果您擺脫了namespace參數，一切都將按預期工作。
