A much better solution than patching the rails helpers would be to add
the following to public/javascripts/application.js (it adds a nice
little fade in and fade out too):
Ajax.Responders.register({
onCreate: function() {
new Effect.Appear('loading', { duration: 0.3 });
},
onComplete: function(request, transport, json) {
if (0 == Ajax.activeRequestCount) {
new Effect.Fade('loading', { duration: 0.3 });
}
if(!request.success()) {
alert('An error occurred while processing this request');
}
}
});
