ruby-on-rails - NoMethodError(# 的未定义方法 `password_digest='

Question

在 Controller 中:

def createUserForHotel
  @user=User.new(params_createUserForHotel)
  if @user.save
    flash[:notice]="New user is created for the hotel"
    redirect_to(:controller=>'hotels',:action=>"createnewhotel")
  else
    flash[:notice]="New user not created "
    redirect_to(:controller=>'hotels',:action=>"createnewhotel")
  end
end

def params_createUserForHotel
  params.require(:user).permit(:username,:password,:email,:hotel_id)
end

迁移中:

def up
  create_table :users do |t|
    t.string "first_name",:limit=>25
    t.string "last_name",:limit=>50
    t.string "email",:null=>false,:limit=>100
    t.string "username",:limit=>50  
    t.string "password",:limit=>40 
    t.integer "hotel_id"
    t.timestamps
  end

  add_index("users","hotel_id")
end

class AlterUsers < ActiveRecord::Migration
  def up          
    rename_column("users","password","hashed_password")   
  end

在 Heroku 日志中:

←[0m Started POST "/hotels/createUserForHotel" for 122.50.216.93 at 2014-11-16 10:18:16 +0000

我的应用程序在开发环境中运行良好，但我在 Heroku 日志中收到上述错误。我已在 Heroku 中部署了我的应用程序。

您的password列应命名为password_digest - 而不是hashed_pa​​ssword或password
