Try to implement django_fluent_comments. It works perfectly with another clsses, but with News I have the following error (though the classes are mostly similar):
AttributeError at /admin/fluent_comments/fluentcomment/
'News' object has no attribute 'get_absolute_url'
The Traceback links me to the comments template:
Error during template rendering
In template /app/.heroku/python/lib/python2.7/site-packages/django/contrib/admin/templates/admin/change_list.html, error at line 91
'News' object has no attribute 'get_absolute_url'
I don't want to add a get_absolute_url method to the "news" class because I don't understand why in other cases it works without it.
