You are right. Catching and re-raising the exception is used if you want to do something when the exception happens but you don't want to fully handle the exception. For example, if you would like to log it but you don't want to be responsible for handling the problem. If in your case catching the exception to update the flash is enough then that's all you need and you don't have to re-raise. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
