Fairly simple question that I''d *thouhgt* I''d seen answered before, but can''t seem to find now. A user has_many foos. I want to present a user with a list of possible foos and have them choose which ones he wants to add to his foo array. I''m using a form that has a checkbox for each foo. I get the array foo_ids back from params no problem and then use user.foos.replace() to update the array. But then I make foo acts_as_taggable. I want to show the user only a list of foos tagged with bar in the form. I''m looking to update only part of the array. I thought I''d read (somewhere) that params would contain a hash that would have each foo_id and a value of the check (true/false) so that I could use foos.replace to update the user''s foos. But instead, params[foo_id] is an array of only the checked items from the form. So I''m missing the foos the user has deselected. Is there some way to configure the form such that I get the ids of the unchecked items? Did I miss something simple? thx, --dwf -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
