I have a collection\_select dialog that I have for selecting Users on a  
page. I am wanting the selection to remember and display the last  
selected user from the database. Every time I refresh the page it is  
going back to its default value even though the data has changed. Is  
there a way to tell it to take the data that appears in the database  
and not reset the selection tag like it a new value.

Here is my code that I’m using.  
\<% @users = User.list\_all\_testers %\>  
\<%= collection\_select(:machine, :user\_id, @users, :id, :fullname,  
options = {:include\_blank=\>true}, html\_options = {:onChange =\>  
remote\_function(:update =\> “ajaxmessage”, :url =\> {:action =\>  
‘update\_machine\_user’,  
:controller =\>  
‘manage\_machines’,:id=\>machine.id},:with=\>"‘users\_id=’+this.value")})  
%\>

Thanks William

I assume you have the Ajax and the update parts right. It is a  
question of populating the right value into @machine.

This is NOT working. See  
[http://rails.lighthouseapp.com/projects/8994/tickets/1138-collection\_select-doesnt-select-current-choice](http://rails.lighthouseapp.com/projects/8994/tickets/1138-collection_select-doesnt-select-current-choice)  
for details.  
Id is a FixNum value while the selected value is transfered as a String  
value.

So value and selected can never be the same in option\_value\_selected? If  
value is FixNum!
