ruby-on-rails-3 - ActionMailer::Base Dynamic :来自电子邮件地址

Question

我如何在我的电子邮件邮件程序中更改此代码，以便当 current_user 从应用程序发送电子邮件时，收件人会收到它:from => current_user.email。

目前它来自“notification@example.com”，但我希望它能动态改变，这是否可能导调用子邮件变成垃圾邮件？

class EmailMailer < ActionMailer::Base
    default :from => "notification@example.com"

    def email_listing(user, listing, email)
        @user = user 
        @listing = listing
        @email = email
        @url  = "www.example.com"

        mail(:to => @email.email, :subject => @user.name)
    end
end 

Answer 1

您可以只传递 from 选项以添加自定义发件人地址，并将回复地址的 reply_to 选项传递到 mail 方法中，例如

def email_listing(user, listing, email)
  @user = user 
  @listing = listing
  @email = email
  @url  = "www.example.com"

  mail(:to => @email.email, :subject => @user.name, from: 'notification@example.com', reply_to: @user.email)
end
