Specify authentication database in mongoid.yml

Question

I'm trying to authenticate through mongoid.yml, but the user I want to authenticate as is in the admin database. If I try to specify the admin database in the database field, it will put all the collections in there too and I don't want that.

Is there a way to set my database field to a database I want, but specify a separate authentication database? Heres my mongoid.yml file at the moment

development:
  sessions:
    default:
      database: XC_DEV
      hosts:
        - IP:PORT
      username: user
      password: password

The question is over a year old but it deserves an answer.

Yes, the auth_source option specifies the authentication database. You got to be on mongoid 5.0.0 or higher (documentation on the mongodb website ). Note mongoid defaults to the the admin database.

Can't find such an option for the Mongoid 4 configuration. I created authentications on the actual databases (there could be a way I am not aware of).

Segment of mongoid.yml (5.0.0):

development:
  clients:
    default:
      database: database_name
      hosts:
        - localhost:27017
      options:
        # The name of the user for authentication.
        user: "<%= Rails.application.secrets.mongoid['user'] %>"
        # The password of the user for authentication.
        password: "<%= Rails.application.secrets.mongoid['password'] %>"
        # The user's database roles.
        roles:
          - 'dbOwner'
        # Change the default authentication mechanism. Valid options are: :scram,
        # :mongodb_cr, :mongodb_x509, and :plain. (default on 3.0 is :scram, default
        # on 2.4 and 2.6 is :plain)
        # auth_mech: :scram
        # The database or source to authenticate the user against. (default: admin)
        auth_source: admin
