Method: Devise::Models.config

Defined in:
lib/devise/models.rb

.config(mod, *accessors) ⇒ Object

Creates configuration values for Devise and for the given module.

Devise::Models.config(Devise::Models::DatabaseAuthenticatable, :stretches)

The line above creates:

1) An accessor called Devise.stretches, which value is used by default;

2) Some class methods for your model Model.stretches and Model.stretches=
   which have higher priority than Devise.stretches;

3) And an instance method stretches.

To add the class methods you need to have a module ClassMethods defined inside the given class.
