ruby-on-rails - Heroku 上的应用程序错误 : An error occurred in the application and your page could not be served

Question

有一个正在开发但已部署问题的工作 Rails 应用程序。最近在工作，但在添加 clouldmailin 后似乎会导致一些依赖性问题？非常感谢任何有助于理解日志中问题的帮助。

Answer 1

正如@muistooshort 所说和日志指出的那样，类名需要大写，因为这就是 ruby​​ 识别哪些类和对象类型与常规变量名或方法调用的方式。

这是您日志的相关部分:类/模块名称必须是 CONSTANT

因此，将您的电子邮件 Controller 类声明更改为:

class EmailController < ApplicationController

并重新部署。
