我需要解密由devise生成的密码.

例如,我的密码是test123test.设计生成此密码:

$2a$10$vGeVVu.E0XGjlNEa0xMCK.R0SEH0aFuyJpefrq01Axz6WSbHApPEu 

我需要解密密码并发送test123test.

我正在尝试使用设计恢复用户的密码,但它会生成以下错误

undefined method `reset_password_sent_at=' for #<User:0x007fb78cfafb68>

任何人都可以帮助我,因为我是Ruby on Rails的新手？

使用Devise恢复密码和向用户发送电子邮件的最佳方法是什么？非常感谢你...

我用的是装饰(2.2.3)

User.rb

require 'digest/md5'

class User < ActiveRecord::Base


  # Setup accessible (or protected) attributes for your model
  belongs_to :shop

  before_create :compute_email_md5

  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable,
    :recoverable,
    :rememberable,
    :trackable,
    :validatable,
    :token_authenticatable


  # Setup accessible (or protected) attributes for your model
  attr_accessible :email,
    :email_md5,
    :password,
    :password_confirmation,
    :shop_id,
    :role,
    :terms,
    :name,
    :notify_on_order_received

  validates :terms, :acceptance => true, :on => …

我需要从另一个控制器调用方法.什么是最好的方法？例如:

catalogues_controller.rb

class Site::CataloguesController < ApplicationController
  respond_to :js, :html

  def index
    produc_list # call method other controller
  end
end

other_controller.rb

class OtherController < ApplicationController

  respond_to :js, :html

  def produc_list
     myObj = Catalagues.find(params[:id])
     render :json => myObj
  end
end

我无法在现有表中添加外键,我的第一次迁移是:

public function up() {
    Schema::create('clases_inventario', function($t) {
                $t->increments('id');
                $t->integer('grupos_inventario_id');
                $t->integer('laboratorio_id');
                $t->string('codigo', 4);
                $t->string('descripcion', 64);
                $t->boolean('estado')->default(true);
                $t->timestamps();
            });
}

我的第二次迁移是添加forein键

public function up() {

        Schema::table('clases_inventario', function($table) {
                    $table->foreign('grupos_inventario_id')->references('id')->on('grupos_inventario');
                });
    }

然后我运行php artisan migration并输出下一个错误
