Is there a way to tell collection_select to use a specific ID then
other than machine_user_id. That is what I was originally trying to
do so I did not have to go down into the object from the form .
I was trying to get around it by using a call to a form $("#
{machine.fqdnj}").machine[user_id].selectedIndex= and it did not seem
to work. When I was trying this with a standard html setup with
prototype I found that it would not accept a variable being passed
into $() but if I set the name using a static name it seemed to work.
