Hi All, I'm having a slight issue with one of my Rails models. It's nothing I can't work around (as I've already done so), but I'm interested in the actual issue.

Hi all, here's a beginner rails question... After I do: format.xml { head: ok} How do I return from the controller endpoint without showing the view?

I perform a lot of tests that create e-mail messages. I store each message in separate eml file. (I can change file extension if needed.)
