如何在我的 ActionMailer 视图中使用我的视图助手? [英] How to use my view helpers in my ActionMailer views?

问题描述

我想在我的 ReportMailer 视图 (app/views/report_mailer/usage_report.text.html.erb) 中使用我在 app/helpers/annotations_helper.rb 中定义的方法>).我该怎么做?

I want to use the methods I defined in app/helpers/annotations_helper.rb in my ReportMailer views (app/views/report_mailer/usage_report.text.html.erb). How do I do this?

基于本指南，看起来add_template_helper(helper_module) 方法可能会做什么我想要，但我不知道如何使用它.

Based on this guide it seems like the add_template_helper(helper_module) method might do what I want, but I can't figure out how to use it.

(顺便说一句，您是否有理由在邮件程序视图中访问一组不同的帮助程序?这很烦人.)

(BTW, is there a reason you get access to a different set of helpers in mailer views? This is pretty annoying.)

推荐答案

在您用来管理电子邮件的邮件程序类中:

In the mailer class that you are using to manage your emails:

class ReportMailer < ActionMailer::Base
  add_template_helper(AnnotationsHelper)

  ...
end
