Ruby on rails Rails-FriendlyID&；祖先

我正在尝试用自定义函数构建slug。我面临的问题是，当我尝试连接到具有祖先的类别时，FriendlyID正在将

/

替换为

%2F

我正在这样做：

class Category < ActiveRecord::Base
  extend FriendlyId
  friendly_id :set_ancestry_slug, use: :slugged

  def normalize_friendly_id(string)
    string
  end

  def set_ancestry_slug
    url = ""
    if self.ancestry?
      self.ancestors.each do | an |
        url += "#{an.title.parameterize}/"
      end
    end
    url += self.title.parameterize
    return url
  end

end

连接到类别时

您是否找到了解决方案。我也在尝试使用友好的id和祖先，我想创建嵌套资源。@user2012677-不，我必须重新考虑结构：(
