Rails - Dec 2005 - Passing multiple parameters with select-option to controller

Hi all,

I''m using Windows Xp, Mysql 5, Webrick, Rails 1.0 I''ve 3
tables which
have HABTM relationship. My tables names are all set to uncountble. Name 
of tabels are anabilimdali (includes department info id name etc.), 
ogretimuye (personel information like id , name , dept. ) yayin 
(document information), and for relationships yayin_anabilimdali  , 
yayin_ogretimuye .

The relationship between yayin_anabilimdali is ok. But i can''t write
any
parameters to yayin_ogretimuye table when I try to create new yayin 
object. The object was successfully creted in yayin table and the 
relationship was successfully created in yayin_anabilimdali table.  Here 
is the codes;


model


yayin.rb

class Yayin < ActiveRecord::Base
has_and_belongs_to_many :ogretimuye
has_and_belongs_to_many :anabilimdali
end




controller


yayin_controller.rb

class YayinController < ApplicationController
model :yayin

....
....

def new
    @anabilimdali = Anabilimdali.find (:all , :order => "ad")
    @ogretimuye = Ogretimuye.find (:all , :order => "ad")
  end

def create
    @anabilimdali = Anabilimdali.find_all
    @ogretimuye = Ogretimuye.find_all
    item = Yayin.new
    item.attributes = @params["yayin"]



    if item.save
      for anabilimdali in @anabilimdali
          if (@params[anabilimdali.ad])

              item.anabilimdali<<(anabilimdali)
           end
       end



       for ogretimuye in @ogretimuye

        if (@params[ogretimuye[ogretimuye.id] == ogretimuye.id )

               item.ogretimuye<<(ogretimuye)

         end
       end
        redirect_to(:action => "list")
    else
        render_text "Couldn''t add new item"
    end
end
...
...



View


new.rhtml



<h1>New yayin</h1>

<%= start_form_tag :action => ''create'' %>
  <%= render :partial => ''form'' %>



<p><label
for="yayin_anabilimdali">Anabilimdallları</label><br />
        <% for @anabilimdali in @anabilimdali %>
        <%= @anabilimdali.ad %> : <input type="checkbox"
name="<%=
@anabilimdali.ad %>" value="0"/><br />
        <% end %>
    </p>

<p><label
for="yayin_ogretimuye">Yazarlar</label><br />

        <%for ogretimuye in @ogretimuye%>

        <select name=ogretimuye[ogretimuye.id][] multiple>
        <option value="<%=ogretimuye.id%>">
<%=ogretimuye.ad%>
<%=ogretimuye.soyad%> </option>
        <%end%>
</p>
		</select>

   <%= submit_tag "Create" %>
<%= end_form_tag %>

<%= link_to ''Back'', :action => ''list''
%>
