django url templatetag无法撤消url

Question

我正在使用django-facebook，并且由于一些奇怪的原因它停止了工作。 当然，我改变了一些东西，某处发生了。 但是你可能已经猜到我现在一无所知。

我得到的错误消息：

TemplateSyntaxError at /facebook/connect/

Caught TypeError while rendering: unhashable type: 'dict'

 Template error

 In template /home/jonasg/.virtualenvs/wiespeeltwaar/lib/python2.6/site-packages/django_facebook/templates/django_facebook/connect.html, error at line 87

 86     <!--form to call registration via facebook -->
 87     <form action="{% url facebook_connect %}?facebook_login=1" method="post">
 88     <h2>Register, login or connect with facebook</h2>

由于某种原因，网址模板标签无法提供facebook_connect视图的网址。

任何帮助表示赞赏！

Answer 1

该错误实际上不在url标记中，只是该标记导致导入有问题的代码。 在某处你试图使用字典作为字典键。

Answer 2

在代码中的某个地方，这是一个相当困难的调试。

看看堆栈跟踪：

包装器中的/home/jonasg/django-wiespeeltwaar/django/utils/functional.py

if mem_args in cache:

    ...

▼ Local vars
Variable    Value
mem_args    

({'backend': 'wiespeeltwaar.accounts.backends.WswBackend',
  'form_class': <class 'registration.forms.RegistrationFormUniqueEmail'>},)

args    

({'backend': 'wiespeeltwaar

.accounts.backends.WswBackend',
  'form_class': <class 'registration.forms.RegistrationFormUniqueEmail'>},)

num_args

似乎我发现事情发生了可怕的错误。 （u'facebook_connect'，）：'facebook_connect'，这条线看起来并不正确！
