Ruby on rails 用户邮件程序失败

我在我的用户模型中设置了一个进程，将一群@users发送到一个邮件脚本User_mailer.rb

class UserMailer < ActionMailer::Base
    def mail_out(users)
    @recipients = { }
    users.each do |user|
      @recipients[user.email] = { :zipcode => user.zipcode }
    end


    from        "no-reply@dailytrailer.net"
    subject     "Check out the trailer of the day!"
    body        :user => user
  end

end

我正在使用该应用程序发送电子邮件。用户正在访问用户邮箱，但我从那里得到一个错误。谁能给我指一下正确的方向吗

用户模型：

class User < ActiveRecord::Base

  acts_as_authentic

  def self.mail_out

    weekday = Date.today.strftime('%A').downcase

    @users = find(:all, :conditions => {"#{weekday}sub".to_sym => 't'})




    UserMailer.deliver_mail_out(@users)



  end

end

用户数据库模式

  create_table "users", :force => true do |t|
    t.string   "email"
    t.date     "birthday"
    t.string   "gender"
    t.string   "zipcode"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "crypted_password"
    t.string   "password_salt"
    t.string   "persistence_token"
    t.string   "mondaysub",         :default => "f", :null => false
    t.string   "tuesdaysub",        :default => "f", :null => false
    t.string   "wednesdaysub",      :default => "f", :null => false
    t.string   "thursdaysub",       :default => "f", :null => false
    t.string   "fridaysub",         :default => "f", :null => false
    t.string   "saturdaysub",       :default => "f", :null => false
    t.string   "sundaysub",         :default => "f", :null => false
  end

我不确定这是否是完整的解决方案（您得到了什么错误？），但这是需要修复的问题：在

body:user=>user

行中，未定义

user

变量。你的意思是做

：user=>@recipients

？

我在你的代码中注意到的一件事是，你的mailer类不是从Postage:：mailer派生的

因此，首先确保已安装最新的PostageApp插件，然后查看以下示例代码：

这里还有一个示例应用程序：

我在代码中注意到的另一个细节是

body:user=>user

不需要，因为您没有在视图中使用

user

变量，除此之外，正如Alex提到的，在该点上没有定义它

希望有帮助

你收到的错误是哪一个？很抱歉忘记添加它，我将它放在了问题中。很抱歉忘记添加它，我将它放在了问题中。我尝试了一下，没有出现错误：）非常感谢。
