ruby on rails - Mongoid OR query syntax

Question

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?

Answer 1

For the sake of others who end up on this page, the updated syntax is now

Username.or({username: @username}, {email: @email})

Please refer to the updated docs or relevant impl.
