Re: [Catalyst] Command-line utility using Controller - examples?

That's actually what I ended up doing, just loading the Schema classes directly and adding the bit of extra handling that I wanted from the Controller.

In some cases it's handy for the application to handle these tasks. I suspect that's one reason C::P::Scheduler is around. One case might be sending emails triggered by a cron job that include a self referencing url back to the application. Note, I said handy, not required. Probably better to write out a base URL when the app starts and then have the cron job use that. But, the infrastructure that Catalyst provides can make doing this in the application tempting. It's up to you if you want to give up those request cycles to other things than web requests. -- Bill Moseley [EMAIL PROTECTED] ___ List: Catalyst@lists.rawmode.org Listinfo: http://lists.rawmode.org/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.rawmode.org/ Dev site: http://dev.catalyst.perl.org/
