I found the solution ! :-) The problem was that I used acts_as_taggable_on_steroids plugin which does not work on Rails 3.2 ...
Since "Author" is the only model which has a :name attribute, I thought that the problem came from Author ... but the problem was in the Tag model (which is in the acts_as_taggable_on_steroid plugin). Indeed, its :name attribute is not "accessible". So, I use the acts_as_taggable_on gem (https://github.com/mbleigh/acts-as-taggable-on) which correctly works on Rails 3.x -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
