# Includes devise_for method for routes. This method is responsible to
# generate all needed routes for devise, based on what modules you have
# defined in your model.
#
# ==== Examples
#
# Let's say you have an User model configured to use authenticatable,
# confirmable and recoverable modules. After creating this inside your routes:
#
# devise_for :users
#
# This method is going to look inside your User model and create the
# needed routes:
#
# # Session routes for Authenticatable (default)
# new_user_session GET /users/sign_in {:controller=>"devise/sessions", :action=>"new"}
# user_session POST /users/sign_in {:controller=>"devise/sessions", :action=>"create"}
# destroy_user_session GET /users/sign_out {:controller=>"devise/sessions", :action=>"destroy"}
#
# # Password routes for Recoverable, if User model has :recoverable configured
# new_user_password GET /users/password/new(.:format) {:controller=>"devise/passwords", :action=>"new"}
# edit_user_password GET /users/password/edit(.:format) {:controller=>"devise/passwords", :action=>"edit"}
# user_password PUT /users/password(.:format) {:controller=>"devise/passwords", :action=>"update"}
# POST /users/password(.:format) {:controller=>"devise/passwords", :action=>"create"}
#
# # Confirmation routes for Confirmable, if User model has :confirmable configured
# new_user_confirmation GET /users/confirmation/new(.:format) {:controller=>"devise/confirmations", :action=>"new"}
# user_confirmation GET /users/confirmation(.:format) {:controller=>"devise/confirmations", :action=>"show"}
# POST /users/confirmation(.:format) {:controller=>"devise/confirmations", :action=>"create"}
#
# ==== Options
#
# You can configure your routes with some options:
#
# * :class_name => setup a different class to be looked up by devise, if it cannot be
# properly found by the route name.
#
# devise_for :users, :class_name => 'Account'
#
# * :path => allows you to setup path name that will be used, as rails routes does.
# The following route configuration would setup your route as /accounts instead of /users:
#
# devise_for :users, :path => 'accounts'
#
# * :singular => setup the singular name for the given resource. This is used as the instance variable
# name in controller, as the name in routes and the scope given to warden.
#
# devise_for :users, :singular => :user
#
# * :path_names => configure different path names to overwrite defaults :sign_in, :sign_out, :sign_up,
# :password, :confirmation, :unlock.
#
# devise_for :users, :path_names => { :sign_in => 'login', :sign_out => 'logout', :password => 'secret', :confirmation => 'verification' }
#
# * :controllers => the controller which should be used. All routes by default points to Devise controllers.
# However, if you want them to point to custom controller, you should do:
#
# devise_for :users, :controllers => { :sessions => "users/sessions" }
#
# * :failure_app => a rack app which is invoked whenever there is a failure. Strings representing a given
# are also allowed as parameter.
#
# * :sign_out_via => the HTTP method(s) accepted for the :sign_out action (default: :get),
# if you wish to restrict this to accept only :post or :delete requests you should do:
#
# devise_for :users, :sign_out_via => [ :post, :delete ]
#
# You need to make sure that your sign_out controls trigger a request with a matching HTTP method.
#
# * :module => the namespace to find controllers (default: "devise", thus
# accessing devise/sessions, devise/registrations, and so on). If you want
# to namespace all at once, use module:
#
# devise_for :users, :module => "users"
#
# Notice that whenever you use namespace in the router DSL, it automatically sets the module.
# So the following setup:
#
# namespace :publisher do
# devise_for :account
# end
#
# Will use publisher/sessions controller instead of devise/sessions controller. You can revert
# this by providing the :module option to devise_for.
#
# Also pay attention that when you use a namespace it will affect all the helpers and methods for controllers
# and views. For example, using the above setup you'll end with following methods:
# current_publisher_account, authenticate_publisher_account!, publisher_account_signed_in, etc.
#
# * :skip => tell which controller you want to skip routes from being created:
#
# devise_for :users, :skip => :sessions
#
# * :only => the opposite of :skip, tell which controllers only to generate routes to:
#
# devise_for :users, :only => :sessions
#
# * :skip_helpers => skip generating Devise url helpers like new_session_path(@user).
# This is useful to avoid conflicts with previous routes and is false by default.
# It accepts true as option, meaning it will skip all the helpers for the controllers
# given in :skip but it also accepts specific helpers to be skipped:
#
# devise_for :users, :skip => [:registrations, :confirmations], :skip_helpers => true
# devise_for :users, :skip_helpers => [:registrations, :confirmations]
#
# * :format => include "(.:format)" in the generated routes? true by default, set to false to disable:
#
# devise_for :users, :format => false
#
# * :constraints => works the same as Rails' constraints
#
# * :defaults => works the same as Rails' defaults
#
# ==== Scoping
#
# Following Rails 3 routes DSL, you can nest devise_for calls inside a scope:
#
# scope "/my" do
# devise_for :users
# end
#
# However, since Devise uses the request path to retrieve the current user,
# this has one caveat: If you are using a dynamic segment, like so ...
#
# scope ":locale" do
# devise_for :users
# end
#
# you are required to configure default_url_options in your
# ApplicationController class, so Devise can pick it:
#
# class ApplicationController < ActionController::Base
# def self.default_url_options
# { :locale => I18n.locale }
# end
# end
#
# ==== Adding custom actions to override controllers
#
# You can pass a block to devise_for that will add any routes defined in the block to Devise's
# list of known actions. This is important if you add a custom action to a controller that
# overrides an out of the box Devise controller.
# For example:
#
# class RegistrationsController < Devise::RegistrationsController
# def update
# # do something different here
# end
#
# def deactivate
# # not a standard action
# # deactivate code here
# end
# end
#
# In order to get Devise to recognize the deactivate action, your devise_for entry should look like this,
#
# devise_scope :owner do
# post "deactivate", :to => "registrations#deactivate", :as => "deactivate_registration"
# end
#
