Hey Kevin;

Nope, that syntax comes straight from the RailsGuides:

http://guides.rubyonrails.org/association_basics.html#scopes-for-has-many-order

See specifically section 4.3.3.1:

4.3.3.1 where

The where method lets you specify the conditions that the associated object
must meet.
    class Customer < ActiveRecord::Base
   has_many :confirmed_orders, -> { where "confirmed = 1" },
     class_name: "Order"
 end
