friendly-id

问题 I noticed on the docs it says: Previous versions of FriendlyId appended a numeric sequence to make slugs unique, but this was removed to simplify using FriendlyId in concurrent code. Is there any way to revert back to this format? My model only has name so there aren't any other viable slug candidates and ( time or date wouldn't make sense in this case for slug candidates). How can I change this (current format): car.friendly_id #=> "peugeot-206" car2.friendly_id #=> "peugeot-206-f9f3789a

问题 Is there any way to get the real id column from a model that is modified with friendly_id? I don`t want to make another db query for it, in performance reasons. 回答1: Broadly speaking friendly_id modifies to_param and find methods. Next should work: @affiche = Affiche.find(params[:id]) # params[:id] is a slug @id = @affiche.id 回答2: Have you tried attributes["id"] ? e.g: Model.first.attributes["id"] 来源： https://stackoverflow.com/questions/7944908/friendly-id-and-real-id

问题 I've set up the friendly_id gem, following along to the RailsCasts Screencast on it. Locally this works brilliantly, I installed it, ran through User.find_each(&:save) which successfully updated the slug field on each of the existing users and all was fine. I have now pushed this to Heroku, and although it works fine for any new members that are added, Heroku isn't updating the user slug for me for already existing Users. Running heroku run console and then User.find_each(&:save) just does
