ruby-on-rails - Friendly_Id 和保留字——如何替换保留字？

Question

这是导致错误的示例:

ruby-1.9.2-p290 :004 > Post.new(title: "new").save!
   (0.3ms)  BEGIN
  post Load (0.3ms)  SELECT `posts`.* FROM `posts` WHERE (`slug` = 'new' OR `slug` LIKE 'new--%') ORDER BY LENGTH(`slug`) DESC, `slug` DESC LIMIT 1
   (0.3ms)  SELECT 1 FROM `posts` WHERE `posts`.`lsi_post_id` = BINARY '' LIMIT 1
   (0.1ms)  ROLLBACK
ActiveRecord::RecordInvalid: Validation failed: Friendly is reserved

我想在 Post 模型中添加一些东西，可能会用“-”或类似的东西替换新词，但我不确定从哪里开始。

谢谢!

根据 daemonsy 和 SizzlePants 的回答，我想到了这个，它悄悄地将“new”重命名为“new2”，将“edit”重命名为“edit2”，并且保持其他一切和以前一样:

class Page < ActiveRecord::Base

  extend FriendlyId
  friendly_id :friendly_id_title, use: :slugged
  def friendly_id_title
    case title.parameterize
    when 'new' then 'new2'
    when 'edit' then 'edit2'
    else title
    end
  end

end
