我無法使「accep_nested_attributes_for：people」 正常工作。目標是讓用戶（在我的應用程序中稱爲「人員」）能夠在註冊時建立姓氏。家庭與人分離。我已經閱讀了很多堆棧溢出帖子，但沒有一個解決方案似乎工作。出現此錯誤的重複主題是忘記將：people_attributes添加到attr_accessible。我相信我已經做對了。我可能會忘記控制器中的某些東西。帶有嵌套屬性的質量分配錯誤
我有一個家庭一個一對多的關係，人
這裏是我的相關代碼：
系列型號：
class Family < ActiveRecord::Base
attr_accessible :name, :people_attributes
has_many :adventures
has_many :people
accepts_nested_attributes_for :people
end
角色模型
class Person < ActiveRecord::Base
attr_accessible :age, :first_name, :last_name, :nickname, :family_id, :password, :password_confirmation
belongs_to :family
has_many :reviews
has_secure_password
end
家庭觀
<%= form_for(@family) do |f| %>
<% if @family.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@family.errors.count, "error") %> prohibited this family from being saved:</h2>
<ul>
<% @family.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<table>
<tr>
<td class="form-cell"><%= f.label :name %></td>
<td class="form-cell"><%= f.text_field :name %></td>
</tr>
<tr>
<td class="form-cell"><%= f.fields_for :person do |ts| %></td>
