Another strange Django error

If you stumble across the error in Django 1.3:

  ...
  File "/Users/brad/work/django-formwizard/.env/lib/python2.7/site-packages/django/core/urlresolvers.py", line 368, in reverse
    app_list = resolver.app_dict[ns]
  File "/Users/brad/work/django-formwizard/.env/lib/python2.7/site-packages/django/core/urlresolvers.py", line 241, in _get_app_dict
    self._populate()
  File "/Users/brad/work/django-formwizard/.env/lib/python2.7/site-packages/django/core/urlresolvers.py", line 198, in _populate
    p_pattern = pattern.regex.pattern
AttributeError: 'str' object has no attribute 'regex'


Or in Django 1.4:


...

  File "/brew/Cellar/python/2.7.1/lib/python2.7/site-packages/django/core/handlers/base.py", line 101, in get_response
    request.path_info)
  File "/brew/Cellar/python/2.7.1/lib/python2.7/site-packages/django/core/urlresolvers.py", line 300, in resolve
    sub_match = pattern.resolve(new_path)
AttributeError: 'str' object has no attribute 'resolve'



You have probably accidentally left a trailing comma in the URLCONF_ROOT setting, i.e.:


ROOT_URLCONF = 'project.urls',
