This must be asked alot but it is very poorly documented. There is no mention at http://mongoid.org/en/mongoid/docs/querying.html
I'm trying to check whether a user exists (below is an AND query), how can I change it to an OR
type query
Username.where(:username=>@username, :email=>@email)
(Either the email or the username must match).
I have found some pretty complicated ways online including sending a direct javascript (from): http://omarqureshi.net/articles/2010-6-17-using-or-in-mongoid
Surely there must be a simple clear syntax to do this correctly?
