主题：




发件人：

通常，您会将密件抄送的电子邮件地址作为数组传递：

mail(:to => "admin@example.com",
    :bcc => ['first@email.com', 'second@email.com', 'third@email.com'],
    :subject => @subject,
    :body => @body)

但是，由于

@user\u emails

已经是一个电子邮件数组，您应该放弃括号，直接传递实例变量：

mail(:to => "admin@example.com",
    :bcc => @users_emails,
    :subject => @subject,
    :body => @body)

以下描述了创建用户电子邮件数组的正确语法：

@notification_users.each do |user|
    @users_emails << user.email
end

更新2:

通过在调用

mail

函数时直接映射用户电子邮件，可以完全绕过控制器循环：

mail(:to => "admin@example.com",
    :bcc => User.where("users.country_id=?", 36).map(&:email),
    :subject => @subject,
    :body => @body)

谢谢你的评论！如何使用

@notification|u users.each do | user |

和

user.email

？非常感谢：）其他一切看起来都很好？您可能需要尝试传递

@users_电子邮件

。由于

@users\u emails

已经是一个数组，因此可能没有必要像传递单个电子邮件时那样将其包含在数组中，例如，

['first@email.com', 'second@email.com“]

。从理论上讲，人们也可以做

@user\u emails+=[user.email]

。@zeantsoi我在更新之前试过了。实际上，它只向

admin@example.com

：（@users\u电子邮件没有收到任何电子邮件
