Probably, but I can't really tell without having more knowledge of the
underlying controller and views. If you have a button that links to the
change action, it's going to create a response from that action and
whatever routing is associated with that action will be in the url of that
action unless you have told the system to do otherwise. The one thing that
is commonly misunderstood with rendering is that execution remains within
the action that called the render, in this case, the action change. Any
instance variables that are referenced in the view must be defined within
that action. Even the following:
render action: "operation_en_cours"
doesn't really execute the action. It renders a view using the template
associated with the action operation_en_cours. Any information required by
the template from the action (such as instance variables) will need to be
defined in the action that is calling it (in this case, change).
