Ошибка массового присвоения с вложенными атрибутами

Question

У меня возникли проблемы с получением «accepts_nested_attributes_for: people» . Цель состоит в том, чтобы пользователь (так называемый «Человек» в моем приложении) мог установить фамилию при регистрации. Семья находится отдельно от человека. Я прочитал много сообщений о переполнении стека, но ни одно из решений, похоже, не работает. Повторяющаяся тема с этой ошибкой забывает добавить: people_attributes к attr_accessible. Я считаю, что я сделал это правильно. Я могу забыть что-то в контроллере.

У меня есть отношения один-ко-многим с семьей к человеку

Вот мой соответствующий код:

Семейство Модели:

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

    has_many :adventures 
    has_many :people 

    accepts_nested_attributes_for :people 

end 

Person Модель

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 

Семейный номер

<%= 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> 
     <td class="form-cell"><%= ts.label :first_name %></td> 
     <td class="form-cell"><%= ts.text_field :first_name %></td> 
     </tr> 
     <tr> 
     <td class="form-cell"><%= ts.label :last_name %></td> 
     <td class="form-cell"><%= ts.text_field :last_name %></td> 
     </tr> 
     <tr> 
     <td class="form-cell"><%= ts.label :age %></td> 
     <td class="form-cell"><%= ts.text_field :age %></td> 
     </tr> 
     <tr> 
     <td class="form-cell"><%= ts.label :nickname %></td> 
     <td class="form-cell"><%= ts.text_field :nickname %></td> 
     </tr> 
     <tr> 
     <td class="form-cell"><%= ts.label :password %></td> 
     <td class="form-cell"><%= ts.password_field :password %></td> 
    </tr> 
    <tr> 
     <td class="form-cell"><%= ts.label :password_confirmation %></td> 
     <td class="form-cell"><%= ts.password_field :password_confirmation %></td> 
    </tr> 
<% end %> 
<%= f.submit %>

Answer 1

Еще одна темы с accepts_nested_attributes_for это люди пишет это:

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

вместо

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

Если вы проходить :person в fields_for, тогда рельсы будут искать person_attributes.

И вам нужно будет построить человека в контроллере: @family.people.build. Точно так же, как вы создаете новую запись @family для отображения формы, вам нужно создать запись человека, принадлежащую к семейству, для отображения вложенного раздела.
