Namespaced models with Counter Cache

A stack trace would be nice I suppose:

ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column: logga/chats_count: UPDATE "chats" SET "logga/chats_count" = COALESCE("logga/chats_count", 0) + 1 WHERE ("id" = 1)

That last line is where it is erroring, the line in question is:

"#{self.to_s.underscore.pluralize}_count" : where self is the model class e.g. Logga::Chat.
