If you would like to dynamically generate error pages, see [Custom errors page](#custom-errors-page). + NOTE: Certain exceptions are only rescuable from the `ApplicationController` class, as they are raised before the controller gets initialized and the action gets executed. See Pratik Naik's [article](http://m.onkey.org/2008/7/20/rescue-from-dispatching) on the subject for more information. -- cgit v1.2.3
