mail.perform_deliveries = false在ActionMailer拦截器中不起作用

Question

我们正在使用这样的ActionMailer拦截器:

class MailerInterceptor
  def self.delivering_email(message)
    p 1
    if message.to.include?("test2@example.com")
      p 2
      message.perform_deliveries = false
    end
  end
end

Mailer.register_interceptor(MailerInterceptor)

但它似乎没有阻止在生产或我们的测试中向该地址发送消息:

require 'spec_helper'

describe "MailerInterceptor" do
  it "should block sending to certain addresses" do
    expect{ Mailer.user_alert("test1", "test@example.com").deliver }.to change{ ActionMailer::Base.deliveries.count }.by(1)
    expect{ Mailer.user_alert("test2", "test2@example.com").deliver }.to_not change{ ActionMailer::Base.deliveries.count }
  end
end

这是使用rails 3.2.14.

它在测试的第二行打印"2",但仍然发送电子邮件.有任何想法吗？谢谢!

Answer 1

请检查您是否使用ActionMailer #delivery方法,而不是#delivery!因为第二个跳过检查perform_deliveries.
