ruby on rails - Reserved names with ActiveRecord models

Question

I take naming pretty seriously, so I think pretty hard about good names for my ActiveRecord models. However, I frequently come up with a name and it has some conflict with a reserved name, either in the database or Ruby or Rails. Model or field names like set or group. Sometimes the issue isn't immediately apparent either. Is there a list somewhere of names we can't use in our model names and a list for field names?
