Rails Tip: Non-Database Attribute in ActiveRecord SQL Query

ActiveRecord in Rails makes it easy to collect items using SQL commands, but if you want to also add attributes that are not database columns, this is what to do:

class TestObject < ActiveRecord::Base

    Item.where("your sql query").select("#{self.test_attribute} as test_attribute")
