django url templatetag fails to reverse url

Question

I'm using django-facebook and for some strange reason it stopped working. Ofcourse I changed something, somewhere for it to happen. But as you might have guessed I'm clueless for the moment.

The error message I get it:

TemplateSyntaxError at /facebook/connect/

Caught TypeError while rendering: unhashable type: 'dict'

 Method:    GET
 Request URL:   http://dev.wiespeeltwaar.be/facebook/connect/

 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>

For some reason the url templatetag can't give me the url of the facebook_connect view.

Any help is appreciated!

Looks to me like `facebook_connect` is a dict in the context, and that's messing up the url tag. But just a guess. — Izkata, Dec 12 '11 at 01:11
Could you, please, post your urls.py here? I think you got error there. — Ilya, Dec 12 '11 at 00:43

The error isn't actually in the url tag, it's just that that tag causes code to be imported that has a problem. Somewhere you're trying to use a dictionary as a dictionary key.

That's a rather hard to debug, somewhere in your code.

Looking at the stacktrace:

/home/jonasg/django-wiespeeltwaar/django/utils/functional.py in wrapper

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

func    

<function get_callable at 0x9aba2cc>

It seems that I've found the place where things go horribly wrong. (u'facebook_connect',): 'facebook_connect', This line doesn't look right at all!
