Question

我在我的用户模型中设置了一个进程，将一堆@users发送到邮件脚本user_mailer.rb

我正在使用http://postageapp.com应用发送电子邮件。用户正在访问User_mailer但我从那里收到错误。任何人都可以指出我正确的方向。

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

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

mail_out.html.erb

{{zipcode}},

Please check out the trailer of the day at http://www.dailytrailer.net


Thank you!

  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   "mondaysub",         :default => "f", :null => false
    t.string   "tuesdaysub",        :default => "f", :null => false
    t.string   "wednesdaysub",      :default => "f", :null => false

    t.string   "sundaysub",         :default => "f", :null => false
  end

Answer 1

我不确定这是否是完整的解决方案（你得到了什么错误？），但这是需要修复的：在body :user => user行，user变量不是定义。你的意思是:user => @recipients吗？

Answer 2

我在你的代码中注意到的一件事是你的邮件程序类不是从Postage :: Mailer派生的。

首先确保安装了最新的PostageApp插件，然后在这里查看一些示例代码：http://postageapp.com/docs/rails

此处还有一个示例应用：http://blog.postageapp.com/2009/11/rails-example-app/

我在你的代码中注意到的另一个细节是在行中 body :user => user 不需要，因为你没有在你的视图中使用user变量，除了像Alex提到的那样，它在那时没有被定义。

希望有所帮助！
