I keep getting this error: \'str\' object has no attribute \'resolve\'

According to excellent answer posted here: http://redsymbol.net/articles/django-attributeerror-str-object-no-attribute-resolve/

There are generally several sources of this error:

1. You missed 'pattern keyword':

   urlpatterns = ('',
   (r'^$', direct_to_template, {'template' : 'a.html'}),
   # ...
   

   this should be changed to:

   urlpatterns = patterns('',
   (r'^$', direct_to_template, {'template' : 'a.html'}),
   # ...
   

   Note that in Django 1.8+, it's better to use a list of regexes instead of patterns.

   urlpatterns = [
       (r'^$', direct_to_template, {'template' : 'a.html'}),
       ...
   ]
   

2. You missed a comma in some tuple, like:

   (r'^hello/$' 'views.whatever') 
   

3. You commented out some url()s using triple-quotes

4. You carelessly leave a closing bracket in the wrong place:

   (r'^(?P\d{4})/$', 'archive_year', entry_info_dict), 'coltrane_entry_archive_year',
   

   instead of:

   (r'^(?P\d{4})/$', 'archive_year', entry_info_dict, 'coltrane_entry_archive_year'),
   

5. You set ROOT_URLCONF to be a list

6. When migrating from the pattern tuples to a regular list you forgot to remove the empty '' argument of the pattern.

Please check carefully if you don't have one of this cases in your code.
