So, I was updating a few controllers to trap exceptions using something like:
begin @event = Event.find(params[:id] rescue ActiveRecord::RecordNotFound flash[:error] = "Event not found" redirect_to :action => :index end
This worked fine but didn’t seem to be overly “DRY”. Googling a bit, I came across rescue_from and have since replaced all those rescues in my controllers with a single instance of something like:
rescue_from ActiveRecord::RecordNotFound, :with => :invalid_record def invalid_record flash[:error] = "Event not found" redirect_to :action => :index end
Nice! I’m starting to see why Rails kicks serious ass.
