Module: Clickwrap::Registration::ClassMethods

Defined in:
lib/clickwrap/registration.rb

Overview

The optional Devise controller macro. Nothing happens unless a host calls it, and merely loading Clickwrap never requires Devise.

Instance Method Details

#clickwraps_registration_with(policy_key, **options) ⇒ Object

Devise:

class Users::RegistrationsController < Devise::RegistrationsController
clickwraps_registration_with :signup
end

Wraps the resource save so the account and its evidence share one transaction. Devise's own create action remains the implementation of the flow; Clickwrap decorates only the resource's one save call.
