Mailer 确实在引擎中发送邮件答案

【问题描述】：

我正在为一个简单的电子商务系统在 rails 4 中编写一个时事通讯引擎。为此，我在\app\mailers\aecs_newsletter\newsletter_mailer.rb 为我的引擎写了这个邮件：

module AecsNewsletter
    class NewsletterMailer < ::ActionMailer::Base

        default from: 'newsletter@ecommerce.de'

        def send_newsletter_to_subscribers(subscribers, newsletter)
            subscribers.each do |subscriber|
                @email = subscriber.email
                @newsletter = newsletter
                mail(to: @email, subject: newsletter.subject, template_name: 'newsletter')
            end
        end

    end
end

我从::ActionMailer::Base 继承来获取主应用程序的邮件配置。此配置运行良好（通过设计的确认邮件测试）。

但是当我在引擎的控制器中执行函数send_newsletter_to_subscribers 时，函数结束时没有错误，也没有发送邮件。

这里是方法调用的日志：

所以函数渲染了视图，但没有发送邮件。我认为，我没有继承邮件配置的权利。但是我可以通过哪种方式使用主应用程序邮件配置？

有人可以解决我的问题吗？谢谢！

您尚未要求交付。添加 .deliver

module AecsNewsletter
    class NewsletterMailer < ::ActionMailer::Base

        default from: 'newsletter@ecommerce.de'

        def send_newsletter_to_subscribers(subscribers, newsletter)
            subscribers.each do |subscriber|
                @email = subscriber.email
                @newsletter = newsletter
                mail(to: @email, subject: newsletter.subject, template_name: 'newsletter').deliver
            end
        end

    end
end
