Ruby on rails 4 ActionController:：当我使用具有多态关联的嵌套_属性时，在StaplesController中创建未经许可的参数

我绝望了。。。我尝试了所有可能的相关来源的建议，但没有任何帮助。我使用的是ruby 2.0.0 rails 4.1.8和嵌套形式的gem

它仍然会产生相同的错误：

ActionController:：在StaplesControllercreate中取消允许的参数 找到不允许的参数：cqnames 我有一本订书机：

以下是更新现有装订时产生的错误屏幕的内容：

ActionController:：在StaplesController更新中取消允许的参数

找到不允许的参数：cqnames

第68行周围的提取源：

66 |
67 |     def staple_params
68 |         params.require(:staple).permit(:name, :description, allergen_ids: [], cqnames_attributes: [:id, :name, :language, :description, :_destroy] )
69 |     end
70 |  end

app/controllers/staples_controller.rb:68:in'staples_params' app/controllers/staples\u controller.rb:40:在“更新”中

这里是模型装订的_form.html.erb：

使用cqname_fields.html.erb：

如果你知道…，请帮帮我。

对不起，各位。。。它只是在_form.html.erb和_cqname_fields.html中错误地使用了简单的_fields作为方法

正确的版本是

_form.html.erb：

和cqname_fields.html

现在一切都好了-

class Cqname < ActiveRecord::Base
  belongs_to :cqnable, polymorphic: true
end

  private
    def set_staple
      @staple = Staple.find(params[:id])
    end

    def staple_params
      params.require(:staple).permit(:name, :description, allergen_ids: [], cqnames_attributes: [:id, :name, :language, :description, :_destroy] )
    end
