[英]Action not found in Mailer preview

I'm having a weird issue with my TransactionMailer Preview.我的 TransactionMailer 预览有一个奇怪的问题。 I have the file test/mailers/previews/transaction_mailer_preview.rb looking good.我有文件test/mailers/previews/transaction_mailer_preview.rb看起来不错。

When i access http://localhost:3000/rails/mailers/ i can see the TransactionMailer preview and all of its actions and the mailer preview is rendered correctly.当我访问http://localhost:3000/rails/mailers/我可以看到 TransactionMailer 预览及其所有操作，并且邮件程序预览已正确呈现。

However, as soon as i refresh, the mailer disappears from the list and the action cannot be found.但是，一旦我刷新，邮件程序就会从列表中消失并且无法找到该操作。 The issue is fixed if i restart the server, but only for one time, then disappears again!如果我重新启动服务器，问题就解决了，但只有一次，然后又消失了！

Any idea?任何的想法？ Rails 5.2 and MiniTest standard. Rails 5.2 和 MiniTest 标准。

For me this issue came up because I defined the Devise Mailer Preview in the file devise_mailer_preview.rb like this:对我来说，出现这个问题是因为我在文件devise_mailer_preview.rb定义了 Devise Mailer Preview，如下所示：

class Devise::MailerPreview < ActionMailer::Preview

in Rails 5 the convention though seems to use:在 Rails 5 中，约定似乎使用：

class DeviseMailerPreview < ActionMailer::Preview

This fixes the issue of disappearing Mailer Previews after editing.这解决了编辑后邮件程序预览消失的问题。
