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

# New yayin

\<%= start\_form\_tag :action =\> ‘create’ %\>  
\<%= render :partial =\> ‘form’ %\>

Anabilimdalllari  
 \<% for @anabilimdali in @anabilimdali %\> \<%= @anabilimdali.ad %\> :   
 \<% end %\>

Yazarlar

```
    <%for ogretimuye in @ogretimuye%>

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

```

\<%=ogretimuye.soyad%\>   
\<%end%\>

\<%= submit\_tag “Create” %\>  
\<%= end\_form\_tag %\>

\<%= link\_to ‘Back’, :action =\> ‘list’ %\>

You’ll want to ask on the Rails mailing list.
