Question

class SupportMailer < ActionMailer::Base
  default :from => "email1@gmail.com"

  def welcome_email(ticket)
    case ticket.game
    when "gameone"
        @ticket = ticket
        headers["Reply-to"] = "email1+#{ticket.token}@gmail.com"
        headers["Return-Path"] = "email1+#{ticket.token}@gmail.com"
        mail(:from => "email1@gmail.com", :to => ticket.email, :subject => "Welcome to 1 Support Ticket")
    when "gametwo"
        @ticket = ticket
        headers["Reply-to"] = "email2+#{ticket.token}@gmail.com"
        headers["Return-Path"] = "email2+#{ticket.token}@gmail.com"
        mail(:from => "email2@gmail.com", :to => ticket.email, :subject => "Welcome to 2 Support Ticket")
    when "gamethree"
        @ticket = ticket
        headers["Reply-to"] = "email3+#{ticket.token}@gmail.com"
        header["Return-Path"] = "email3+#{ticket.token}@gmail.com"
        mail(:from => "email3@gmail.com", :to => ticket.email, :subject => "Welcome to 3 Support Ticket")
    end
  end
end

我已经设置了我的默认值:from，所以我不明白为什么我一直收到这条消息，我也试图通过标题设置它无济于事。

这是我的设置

ActionMailer::Base.smtp_settings = {
  :address              => "smtp.gmail.com",
  :port                 => 587,
  :domain               => "gmail.com",
  :user_name            => "emailx@gmail.com",
  :password             => "password",
  :authentication       => "plain",
  :enable_starttls_auto => true
}

我只是这样称呼它， SupportMailer.support_response(@message).deliver
我该如何解决？

Answer 1

我注意到您的 case 语句没有默认情况。如果您最终从未在 Mailer 类的方法中调用“mail”方法，您将收到该错误。尝试将您的案例陈述移到您调用 SupportMailer 的地方，也许每个案例都有方法。这样您就永远不会调用 SupportMailer，除非您已经确定了正确的票务游戏。
