In the User model I have...
default_scope order('lower(username) ASC')

however commenting it out didn't help much.

User.first is/was fine...

User Load (0.6ms) SELECT "users".* FROM "users" LIMIT 1
=> #<User id: 34, email: "s.e.... bla bla

User.first.names

ruby-1.9.2-p290 :008 > User.first.names
User Load (0.6ms) SELECT "users".* FROM "users" LIMIT 1
NameError: uninitialized constant User::UserName
