Question

我已经看过http://railscasts.com/episodes/196-nested-model-form-revised并尝试使用我的炼油厂引擎做同样的事情，但是在从管理部分添加记录时我无法看到表单中的嵌套字段，而且我没有收到任何错误。我无法弄清楚到底发生了什么，或者如果我错过任何与炼油厂相关的配置，我可能会这样做。

我在Rails控制台上试过这个：

 Refinery::Extension::Model.nested_attributes_options
 => {:nested_model_name=>{:allow_destroy=>false, :update_only=>false}}

我有两个模型问题和选项，但在提交问题表单时，选项作为嵌套元素，它给我如下错误

  ActiveModel::MassAssignmentSecurity::Error in  Refinery::Papers::Admin::QuestionsController#create

无法批量指定受保护的属性：refinery_papers_options

请求

参数：

{ “UTF8”=＆gt; “中✓”，   “authenticity_token”=＆gt; “中TQL + r60R05 + meVhPBXPPipvL + X3ZNx + 3dCwoThFBn / Y =”，   “问题”=＆gt; {“content”=＆gt;“

aaaaaaaaaa
”，“correct_answers”=＆gt;“a”，   “refinery_papers_options”=＆GT; { “内容”=＆gt; “中
asdfghjklkmnv
”，   “_destroy”=＆gt;“0”}，“position”=＆gt; 0}，“locale”=＆gt;：en}

我的模型和视图是：

问题模型：

    module Refinery
     module Papers
     class Question < Refinery::Core::BaseModel

      self.table_name = 'refinery_papers_questions'

      attr_accessible :content, :correct_answers, :options_attributes, :position

      validates :content, :presence => true, :uniqueness => true

      has_many :options,
        :foreign_key => "refinery_papers_question_id",
        :class_name => "Refinery::Papers::Option",
        :dependent => :destroy

      accepts_nested_attributes_for :options,
        :allow_destroy => true

    end
  end
end 

Option Model:

    module Refinery
       module Papers
         class Option < Refinery::Core::BaseModel

           self.table_name = 'refinery_papers_options'

           attr_accessible :content, :position, :refinery_papers_question_id

           validates :content, :presence => true

           belongs_to :question,
            :class_name => 'Refinery::Papers::Question',
            :foreign_key => :refinery_papers_question_id

          end
        end
      end

在视图中，嵌套字段的形式如下：

<%= f.fields_for :refinery_papers_options do |option_form| %>
   <div class='field'>
     <%= option_form.label :content, "Option" %><br/>
     <%= option_form.text_area :content, :class => "wymeditor widest" %><br/>
    </div>
   <div class='field'>
     <%= option_form.label :_destroy, "Remove Option" -%>
     <%= option_form.check_box :_destroy -%>    
   </div>
 <% end %>

当我在rails控制台上尝试这个时，我得到了这个堆栈

2.0.0p247：007＆gt;炼油厂::论文:: Question.create（{ “内容”=＆gt; “中

”， “correct_answers”=＆gt; “中一个”，   ：refinery_papers_options =＆gt; { “内容”=＆gt; “中

这可能是link 可以帮助。

 has_many :parts,
         :foreign_key => :refinery_page_id,
         :class_name => '::Refinery::PagePart',
         :order => 'position ASC',
         :inverse_of => :page,
         :dependent => :destroy,
         :include => ((:translations) if ::Refinery::PagePart.respond_to?(:translation_class))

accepts_nested_attributes_for :parts, :allow_destroy => true

您在引擎中创建的不同模型的class names可能存在混淆。上面的代码只是refinery core小组如何完成nested attributes concept的一个示例。

我如何使用refinerycms中的嵌套模型属性？
