NoReverseMatch

[tonyfunc]

List of models show up find, but when I try to add an entry I get:

Error during template rendering

In template /usr/local/lib/python2.7/site-packages/mongonaut/templates/mongonaut/document_list.html, error at line 48

Reverse for 'document_detail' with arguments '(u'mplayers', u'Player', u'DDDD7E9F-E2BD-59E9-AED7-476D45E147A8b.device')' and keyword arguments '{}' not found. 1 pattern(s) tried: ['padmin/(?P<app_label>[-\w]+)/(?P<document_name>[-\w]+)/(?P[\w]+)/$']

What could be the problem?
