I have a time consuming action in a controller. So when a user clicks
on this link to this time consuming action, I would like give users a
status bar, saying something like “LOADING…”. How do i do that?
I have used remote_function stuff to show hidden status-indicator in
other parts of the application.
But here its an entire new page that gets loaded and just showing a
hidden progress bar in the current page would’nt help
Whats the best given my case?
