Dear all

I have been trying to get this piece of code working  
[http://pastie.org/236978](http://pastie.org/236978)

 \<% fields\_for "daleel[categories\_attributes][]", category do | category\_form| %\> 

category: \<%= category\_form.select "category\_id", @categories, :prompt =\> "category", :index =\> nil %\>

```
        <% if category.new_record? %>
            <%= link_to_function "remove", "$

```

(this).up(‘.task’).remove()" %\>  
\<% else %\>  
\<%= link\_to\_function “remove”,  
“category\_for\_destroy(this)” %\>  
\<%= category\_form.hidden\_field :id, :index =\> nil %\>  
\<%= category\_form.hidden\_field :should\_destroy, :index  
=\> nil, :class =\> ‘should\_destroy’ %\>  
\<% end %\>

  
\<% end %\>

The problem is this

the select statement should hide the id however, it does not work for  
select and it works for the hidden field. I was trying hard to get it  
working in the past two days. I tried to put :index =\> nil in  
the :options and :html\_options and the same problem did not get  
solved

this concept was gotten from [#75 Complex Forms Part 3 - RailsCasts](http://railscasts.com/episodes/75)

Thanks in advance

any idea

Did you see the note at the bottom of that episode:

“The code for this screencast isn’t the greatest, it requires  
the :index option for the fields and does not work well in Rails 2.  
Instead I recommend going with the approach I show in Advanced Rails  
Recipes”
