Ruby on Rails latest stable (v4.2.1) - 0 notes - Class: ActiveModel::AttributeMethods
method_missing(method, *args, &block) public

Allows access to the object attributes, which are held in the hash returned by attributes, as though they were first-class methods. So a Person class with a name attribute can for example use Person#name and Person#name= and never directly use the attributes hash – except for multiple assigns with ActiveRecord::Base#attributes=.

It’s also possible to instantiate related objects, so a Client class belonging to the clients table with a master_id foreign key can instantiate master through Client#master.
