You can give max_by look.

objects = [some array of objects] object_with_highest_value = objects.max_by {|obj| obj.desired_value }

Depending on the number of records, you may have a more efficient search in the database. I would order the desired attribute in descending order and take the first entry:

 User.order('field DESC').first
