I think the OP wanted to know how to get a model''s singleton class (eigenclass). Unfortunate coincidence of terminology for two completely different things.

On a hunch, I looked up Black''s precise terminology in The Well-Grounded Rubyist and he defines his method like so: def singleton_class ... I believe some level of confusion may have been avoided had I written as he did. Anywho. So, Marnen, any idea why AR-inheriting objects do this? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
