我正在尝试按照Mail_form gem 的文档添加自定义电子邮件模板。该文档指出：

要自定义使用的电子邮件模板，请创建一个名为contact.erb. app/views/mail_form查看此 repo 中的 lib/mail_form/views/mail_form/contact.erb 以了解默认模板的工作原理。

另外，我在 repo 中发现了这个问题并做了同样的事情：

我在初始化程序中创建了一个 mail_for.rb 文件并将 , 添加MailForm::Notifier.template_root = File.join(Rails.root, "app", "views")到文件中。

我在视图中创建了一个 mail_form 目录并添加了一个contact.erb文件并将默认模板复制到其中。

但是，当我重新启动服务器时，出现以下错误：

当我删除文件中的代码时，一切正常mail_form.rb，但我想根据自己的喜好自定义邮件通知。错误说 undefined method template_root=' for MailForm::Notifier:Class，但我不知道它是什么意思。我仍在学习，所以这个错误有点过头了，任何帮助将不胜感激！谢谢！

我面临着同样的问题。令人沮丧的是，他们的文档缺少有关自定义模板的信息。太模糊了 我需要感谢我的一位同事找到了一个快速的解决方案。他在Ruby方面比我熟练得多。

这是他所做的：

  1. 删除/删除mail_form.rb初始化程序中的文件。我的同事认为 gem 已经默认这样做了，在测试了这个理论之后，我猜他是对的。所以你不需要这个文件。
  2. External Libraries在项目树中展开您的文件夹并找到该mail_form文件夹​​。我正在使用 RubyMine，所以我不知道您的软件是否会显示这一点。告诉我是否没有，我将更新我的答案并粘贴初始模板代码。
  3. 在mail_form文件夹中，展开并访问以下文件lib>mail_form>views>mail_form>contact.erb。该.erb文件是 gem 使用的初始模板。
  4. 将上面访问的文件的内容复制/粘贴到contact.erb您之前在目录中的 mail_form 目录中创建的文件中views。这将成为您的自定义模板。
  5. 完成此操作后，您现在可以完全控制电子邮件模板，因此可以根据自己的喜好修改代码。
