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?
You can select a single field in MongoDB using the following syntax: db. yourCollectionName. find({"yourFieldName":yourValue},{"yourSingleFieldName":1,_id:0});
Open Studio 3T and connect to your MongoDB database. Next, open the Import Wizard from the toolbar. Then, choose JSON as the import format. Click OK.
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.
