我对 Rails 非常陌生，并且一直在尝试构建应用程序。一段时间后，我最近为 facebook 安装了 devise 和 omniauth，并取得了巨大的成功。当我阅读 devise 时，我注意到 Devise 内置了一个“忘记密码”模块。
我已经搜索了互联网，但我一生都没有弄清楚如何设置它。有没有指南？我已经工作了几个小时，但我真的没有任何结果。我该如何设置？我正在使用 rails 4.0 和最新版本的设计。
谢谢，
路线
Omrails::Application.routes.draw do
resources :boards
resources :pins
get 'about' => "pages#about"
root :to => 'pins#index'
resources :tests, :birthdays
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
end
设计迁移：
class DeviseCreateUsers < ActiveRecord::Migration
def change
create_table(:users) do |t|
## Database authenticatable
t.string :email, :null => false, :default => ""
t.string :encrypted_password, :null => false, :default => ""
## Recoverable
t.string :reset_password_token
t.datetime :reset_password_sent_at
## Rememberable
t.datetime :remember_created_at
## Trackable
t.integer :sign_in_count, :default => 0, :null => false
t.datetime :current_sign_in_at
t.datetime :last_sign_in_at
t.string :current_sign_in_ip
t.string :last_sign_in_ip
## Confirmable
# t.string :confirmation_token
# t.datetime :confirmed_at
# t.datetime :confirmation_sent_at
# t.string :unconfirmed_email # Only if using reconfirmable
## Lockable
# t.integer :failed_attempts, :default => 0, :null => false # Only if lock strategy is :failed_attempts
# t.string :unlock_token # Only if unlock strategy is :email or :both
# t.datetime :locked_at
t.timestamps
end
add_index :users, :email, :unique => true
add_index :users, :reset_password_token, :unique => true
# add_index :users, :confirmation_token, :unique => true
# add_index :users, :unlock_token, :unique => true
end
end
用户.rb
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :confirmable,
# :lockable, :timeoutable and :omniauthable
devise :database_authenticatable,
:registerable,
:rememberable,
:trackable,
:recoverable,
:validatable,
:omniauthable,
:omniauth_providers => [:facebook]
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me, :name, :birthday, :sex, :address, :mobile, :provider, :uid
has_many :pins, :dependent => :destroy
has_many :boards, :dependent => :destroy
def self.find_for_facebook_oauth(auth, signed_in_resource=nil)
user = User.where(:provider => auth.provider, :uid => auth.uid).first
unless user
user = User.create(name:auth.extra.raw_info.name,
provider:auth.provider,
uid:auth.uid,
email:auth.info.email,
password:Devise.friendly_token[0,20])
end
user
end
