What's the best way to do a javascript alert warning when someone is trying to access a ajax method that requires authentication - for example to rate a recipe, I have a star-based ajax/css interface. To actually add a rating you need to be logged in. When I use the before_filter, it just redirects to the login page - I'd like to show an alert that says something like "to add a rating, please register/ login first" right there - what's the best way to do this?
Your before_filter stuff is just regular code. It can do a render :update for example just as easily as it does a redirect.

That was a helpful answer - thanks Fred.
