Ruby on rails 强参数：扩展控制器并希望将所需参数添加到现有参数

我有以下控制器：

class BoilerplatesController < InheritedResources::Base
  load_and_authorize_resource

  private

  def boilerplate_params
    params.require(:boilerplate).permit(:title)
  end
end

def boilerplate_params
  params.require(:boilerplate).permit(required_params)
end

def required_params
  [:title,
   :intro,
   :lock_version,
   :outro,
   :resources,
   :topic_id,
   :tags,
   :how_to_evaluate,
   :status,
   :priority]
end

def required_params
  super << {findings_attributes: [:id,
                                  :url,
                                  :description,
                                  :screenshot,
                                  :remove_screenshot]
           }
end

类样板控制器

然后我用这个扩展它：

class BoilerplateCopiesController < BoilerplatesController
  defaults instance_name:  'boilerplate',
           resource_class: BoilerplateCopy

  private

  def boilerplate_params
    params.require(:boilerplate).permit(findings_attributes: [:id, :url])
    super
  end
end

类样板复制控制器<样板控制器
默认实例名称：“样板文件”，
资源类：样板副本
私有的
def样板文件参数
参数require（：样板）.permit（结果属性：[:id，:url]）
超级的
终止
终止

似乎扩展字段并没有将新字段添加到现有字段中，而是否决了它们。如何实现这一点？

一种可能的解决方案（或解决办法）是：

样板控制器：

class BoilerplatesController < InheritedResources::Base
  load_and_authorize_resource

  private

  def boilerplate_params
    params.require(:boilerplate).permit(:title)
  end
end

def boilerplate_params
  params.require(:boilerplate).permit(required_params)
end

def required_params
  [:title,
   :intro,
   :lock_version,
   :outro,
   :resources,
   :topic_id,
   :tags,
   :how_to_evaluate,
   :status,
   :priority]
end

def required_params
  super << {findings_attributes: [:id,
                                  :url,
                                  :description,
                                  :screenshot,
                                  :remove_screenshot]
           }
end

样板复印机控制器：

class BoilerplatesController < InheritedResources::Base
  load_and_authorize_resource

  private

  def boilerplate_params
    params.require(:boilerplate).permit(:title)
  end
end

def boilerplate_params
  params.require(:boilerplate).permit(required_params)
end

def required_params
  [:title,
   :intro,
   :lock_version,
   :outro,
   :resources,
   :topic_id,
   :tags,
   :how_to_evaluate,
   :status,
   :priority]
end

def required_params
  super << {findings_attributes: [:id,
                                  :url,
                                  :description,
                                  :screenshot,
                                  :remove_screenshot]
           }
end

def必需参数
super真的没有其他解决方案吗？
