ruby-on-rails - 自定义错误页面 404/500 但收到 500 内部服务器错误

Question

我正在尝试自定义我的 404/422/500 错误页面，但由于某种原因，我得到一个带有“500 内部服务器错误”的空白页面。但是，在另一个项目中，下面的代码可以正常工作。我希望有人可以帮助我。

这是我的代码：

应用程序.rb

module Realbeez
  class Application < Rails::Application
    config.generators do |generate|
      generate.assets false
      generate.helper false
      generate.test_framework  :test_unit, fixture: false
      # For error message customizing
      config.exceptions_app = self.routes
    end
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.2
  end
end

我的路线：

 get '/404', to: "errors#not_found"
 get '/422', to: "errors#unacceptable"
 get '/500', to: "errors#internal_error"

我的控制器错误控制器：

class ErrorsController < ApplicationController

  def not_found
    respond_to do |format|
      format.html { render status: 404 }
    end
  end

  def unacceptable
    respond_to do |format|
      format.html { render status: 422 }
    end
  end

  def internal_error
    respond_to do |format|
      format.html { render status: 500 }
    end
  end

end

我在 rails 服务器中收到以下消息，也许它可以提供帮助：

您可以只自定义“公共”文件夹中的 html 错误页面。你试过了吗？
