我正在尝试创建一个属于Generator的结果。为了创建Result，我在Generator show.html.erb中执行了代码，并在Generator的show.html.erb中渲染表单（Result）。但是，单击子项按钮时，不会调用Result方法。我怎么解决这个问题？没有显示任何错误，所以我不知道哪里出错了。当我在控制台中键入Result.all时，数据库中也没有记录。我遵循将第二个对象与第一个对象关联的方式，但仍然无法使它们正确。请帮帮我。
记录（不知道为什么会这么久。肯定会出现问题）

我不完全清楚为什么有两个生成器表单（可能我遗漏了一些东西），但在某些地方你使用的是单数用户：user_generators_path在其他地方你正在使用users_generators_path 1}}（注意复数用户）。通过rake routes检查哪个是正确的，并修正任何不正确的条目。
