As far as I understood, you want to do a request to the lookup action in
your controller.
I recently discovered this
*select*(object, method, choices, options = {}, html_options = {})
inside your html_options hash you can put something like this
{data: {remote: true, url: url_for(controller: "your controller (if
necessary)", action: "lookup")}}
so whenever you choose an option it will do an ajax request with the
selected value.
Then you just need a handler in that view, or just have a lookup.js.erb
file that handle the controller action
