ruby-on-rails - Rails 6.0.2 ActionMailer 问题：找不到模板

问题描述

我在开发环境中。在 UI 中触发电子邮件时，我在浏览器中收到错误消息：

No template for interactive request
Admins::AdminsController#testmail is missing a template for request formats: text/html

NOTE!
Unless told otherwise, Rails expects an action to render a template with the same name,
contained in a folder named after its controller. If this controller is an API responding with 204 (No Content),
which does not require a template, then this error will occur when trying to access it via browser,
since we expect an HTML template to be rendered for such requests. If that's the case, carry on.

日志显示：

可以在上面看到模板是在错误发生之前呈现的。

我的邮件类：

class TestMailer < ApplicationMailer
  def testmail
    mail(to: 'user@domain.com',
         subject: 'Welcome to My Awesome Site') do |format|
      format.text
    end
  end
end

当然模板放在/app/views/test_mailer/testmail.text.erb.

我在 development.rb 中的邮件服务器配置是

我在 localhost 上运行了 mailcatcher

config.action_mailer.raise_delivery_errors = true
config.action_mailer.perform_caching = false

config.action_mailer.smtp_settings = {
address: 'localhost',
port: 1025
}
config.action_mailer.delivery_method :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = false

我在 Centos 7 上，整个 Rails 应用程序路径中没有特殊字符或空格感谢您的调查。
