我正在使用Denshobato进行双模式聊天功能。我遇到的问题是Denshobato可能需要 conversations_controller 和 messages_controller - 我目前正在将这两个控制器用于我项目中的不同功能。相反，我决定使用 discussion_controller 和 discussion_messages_controller 。当我尝试在employees_meetup_controller的索引中呈现讨论的表单时。我收到未定义的方法'model_name'错误。我写的代码如下。如何设置Denshobato接受我的discussion_controller和discussion_message_controller别名？顺便说一下，我正在使用两个宝石来实现这个功能， denshobato_chat_panel 和 denshobato 。

答案 0 :(得分：0)
您收到此错误是因为@discussion为零。检查您的控制器方法，确保它存在并正确通过。
您收到此错误的原因是ActiveRecord对象使用ActiveModel::Naming模块生成关联的URL帮助程序（如表单应发布到的位置，除非您另行指定）并形成帮助程序（比如你的字段名称的前缀）
