This gets even stranger. The problem is that the parameter from the mulitline collection_select is an array with ONE element! The element is a string "3,5,4,1". To update the habtm I need an array of four integer elements [3,5,4,1]
How can this happen??? :-( jeb On 30 mar, 15:38, jeb <[email protected]> wrote: > I use habtm and a mulitline select to select which publications a > journalist works on. > > class Journalist < ActiveRecord::Base > has_and_belongs_to_many :publications > end > > AND > > class Publication < ActiveRecord::Base > has_and_belongs_to_many :journalists > end > > When I make changes in the select, only the first selected item gets a > record in the habtm table: > > From the log: > Parameters: {"commit"=>"Update Journalist", > "journalist"=>{"publication_ids"=>["3,5,4,1"], }, > "authenticity_token"=>"a7Lws3tWNS+FczclJEYuu4EusVINUsuy6rwLVagMdLk=", > "utf8"=>"✓", "id"=>"7"} > > Then some rows down(!?): > INSERT INTO "journalists_publications" ("publication_id", > "journalist_id") VALUES (3, 7) > > So, what happened to (5,7), (4,7) and (1,7)???? > > Migration: > def self.up > create_table :journalists_publications, :id => false do |t| > t.references :journalist, :publication > end > add_index :journalists_publications, :journalist_id > add_index :journalists_publications, :publication_id > end > > Form: > <%= form_for(@publication, :remote => true) do |f| %> > <%= f.collection_select(:journalist_ids, > Journalist.limit(20).order('id'), :id, :name, {}, {:multiple => true}) > %> > <% end %> > > Controller: > @journalist = Journalist.find(params[:id]) > if @journalist.update_attributes(params[:journalist]) > ... > > Does anyone have a clue? > Rails 3.0.5 -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
