Rails - Aug 2005 - How do you see the :id param inside AJAX?

I''m trying to get an AJAX list built into a Rails page I''m
working
on. The page is an image, and underneath it you can add or remove  
"options" such as t-shirt sizes or what have you.

I''m passing params back to my controller from my view via ajax. I  
might have one of these in the view:

         <%= text_field_tag(''option_title'',
'''',
                                              {:id            =>  
''option-title-field'',
                                                 :size        => 16,
                                                 :class    =>
''option-
title''}) %>

And then in my controller I''m parsing these text_field options thusly:

         option = Option.create({:title        => params[:option_title],
                                                         :price        = 
 > params[:option_price],
                                                         :quantity     
=> params[:option_quantity],
                                                         :image_id =>  
params[:id]})

...but unfortunately, that params[:id] doesn''t work. It comes out null.

Is there some way for me to see my Image''s id from within my AJAX  
calls, so that I can associate my newly created "options" with the  
image they were created from?

Thanks,
Raymond

You need to have a form field that defines the id:
<%= hidden_field_tag "id", @image.id %>

Then you should have the params[:id] at hand in the receiving  
controller action.
