ruby on rails - Undefined method has_attached_file after Paperclip installation? -

-

not sure if i've done right here. added paperclip gem gemfile , did bundle install. followed along readme instructions on paperclips github page.

i wasn't sure if needed install imagemagick. but, found script on github installation on snow leopard, ran:

rails plugin install http://github.com/masterkain/imagemagick-sl.git

but, i'm getting undefined method has_attached_file

i'm new rails , programming. of pretty advanced me, far i've managed figure stuff out.

have restarted rails server?
