Module: Devise::Controllers::UrlHelpers

Defined in:
lib/devise/controllers/url_helpers.rb

Overview

Create url helpers to be used with resource/scope configuration. Acts as proxies to the generated routes created by devise. Resource param can be a string or symbol, a class, or an instance object. Example using a :user resource:

new_session_path(:user)      => new_user_session_path
session_path(:user)          => user_session_path
destroy_session_path(:user)  => destroy_user_session_path

new_password_path(:user)     => new_user_password_path
password_path(:user)         => user_password_path
edit_password_path(:user)    => edit_user_password_path

new_confirmation_path(:user) => new_user_confirmation_path
confirmation_path(:user)     => user_confirmation_path

Those helpers are included by default to ActionController::Base.

In case you want to add such helpers to another class, you can do that as long as this new class includes both url_helpers and mounted_helpers. Example:

include Rails.application.routes.url_helpers
include Rails.application.routes.mounted_helpers
