I think it's probably best to create a new plugin and exception class (which would subclass Sequel::Error). NoExistingObject sounds good, but it indicates a serious issue when updating or deleting, so I don't think it is appropriate to reuse for your purposes. Your find! method would just go in the plugin's ClassMethods, and would raise that error. > (PS: Forme rules.

I haven't had a lot of feedback regarding it, so it you have any, please let me know. Thanks, Jeremy -- You received this message because you are subscribed to the Google Groups "sequel-talk" group.
