I''m trying to generate a form that uses has_many :through and multiple selects. I''m working directly with the join table controller and working with edge rails. I want to generate a list to populate the join table without doing one step over and over again. When items are successfully created they contain the wrong information (Only a single entry and 1 for both join id values. Here''s the code: <p><label for="connection_familytype">Applicable Units</label><br/> <select name="connection[familytype_id][]" id="connection_familytype_ids" multiple="multiple"> <option value="0">All</option> <%option_groups_from_collection_for_select(Familytype.find(:all, :order => "name", :conditions => "parent_id IS NULL and name != ''all''"), "children.find(:all)", "name", "id", "name")%> <br/><br/></select> </p> <% collection_multiple_select( ''connection'', ''producttest_id'', Producttest.find(:all, :order => "name", :conditions => "parent_id > 0"), :id, :name ) %> ###################################### and the dump: undefined method `producttest_ids='' for #<Connection id: nil, familytype_id: 1, producttest_id: 1> vendor/rails/activerecord/lib/active_record/base.rb:2028:in `method_missing'' app/controllers/connection_controller.rb:30:in `create'' -e:4:in `load'' -e:4 Request Parameters: {"commit"=>"Create", "connection"=>{"producttest_id"=>["3", "13", "14"], "familytype_id"=>["10015", "7", "5", "9"]}} ###################################### I would like to see the following generated from the above Join table: 3 10015 3 7 3 5 3 9 13 10015 ... 14 5 14 9 ###################################### Response Headers: {"cookie"=>[], "Cache-Control"=>"no-cache"} ###################################### --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
