Ruby on rails 嵌套属性的质量分配错误

我在获取“接受：人的嵌套属性”时遇到问题 工作。目标是让用户（在我的应用程序中称为“Person”）能够在注册时建立姓氏。一家人和另一个人单独坐在一张桌子上。我已经阅读了很多关于堆栈溢出的文章，但是没有一个解决方案是有效的。这个错误反复出现的主题是忘记将：people\u属性添加到attr\u accessible。我相信我做得对。我可能忘了控制器里有什么东西

我与家人之间有一对多的关系

这是我的相关代码：

家庭模式：

class Family < ActiveRecord::Base
  attr_accessible :name, :people_attributes

  has_many :adventures
  has_many :people

  accepts_nested_attributes_for :people

end

---

另一个主题是

接受

的_嵌套的_属性_，这是人们写的：

<%= f.fields_for :person do |ts| %>

而不是

<%= f.fields_for :people do |ts| %>

如果您在的

字段中传递
：person
，那么rails将查找
person\u属性

您需要在控制器中构建一个人：
@family.people.build
。与创建新的@family记录以显示表单的方式相同，您需要创建属于该族的person记录以显示嵌套部分。
从development.log文件中发布错误的完整堆栈跟踪，请单击“发布”，谢谢JamesW@Robin刚刚发布了正确答案。您错过了堆栈跟踪的重要部分（参数和错误消息）。当我更改时，参数会准确地告诉您错误所在，导致表单的嵌套部分完全消失。这是因为您没有正确构建关联。你这样做了吗
@family.people.build
工作非常感谢。顺便说一句，我创建了一个Git Repo，作为创建具有嵌套属性的Rails表单的示例。
