I am trying to be RESTful. I have users\_controller so that I can see the  
profile of a user via user/:user\_id .

What I want, is to show a select box (drop down) where I see some users.  
I will select a user and click ‘Go’ to go to the user profile page,  
meaning user/:selected\_users\_id

but I cannot get the user\_id selected in the drop down. I could, I would  
write a link\_to helper like this:

link\_to ‘go!’, :action=\>‘show’, :id=\>the value selected in the drop down

any idea how can I do that?
