I’d like to know how I can put the id in a field when the user clicks on  
an  
autocomplete item. I have a field with autocomplete where I wanna show  
the  
name of the user but save on the database the id. My code is the  
following  
one:

\<%= text\_field\_with\_auto\_complete :user\_id, :name, {:size =\> 15}, {:url  
=\>  
users\_path, :method =\> :get, :param\_name =\> ‘search’} %\>

Thanks in advance

Rodrigo,

You can either use a hidden field for the ID or follow the approach  
covered by Ryan B. in the following railscast:

Cheers, Sazima
