Hi all,

I’d like to be able to refer to a form being created by form\_for from  
javascript. To do this, I’d like to know what will be the id and/or  
name that’s going to be set on the form. I understand I can override  
the id or name, but i’d prefer not to.

For instance, I’m looking for something to fill in  
someMethodToGiveMeInputNameFor:

\<% form\_for :role, … %\>  
Press Me\</  
button\>  
\<%= form.select(:rights, … %\>  
\<% end %\>

Thanks in advance!
