Question

Here is an example of what causes the error:

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

I would like to put something in the Post model that maybe replaces a new word with “-” or something along those lines but I’m not sure where to start.

Thank you!

Answer 1

Using the answers by daemonsy and SizzlePants I came up with this, which quietly renames “new” to “new2” and “edit” to “edit2”, and keeps everything else as before:

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
