I have a RESTful setup, where one is for messages. In MessagesController
I have the basic methods. But I have problems when I want to "create"
from another controller. I took the form in new.erb.html from message
view and copied that to a new file in views in a different location, and
another controller. What if I want to have a method in the new
controller called create_message, how should this form_for be changed?
