problème déploiement RailsTutorial Chap 11 sur Heroku

Question

Je suis le tutoriel Rails et vient de terminer Chap 11. Aucune erreur sur localhost, mais un 500 sur heroku. Heroku journaux (ci-dessous) dit "relation" microposts "n'existe pas" suivi de quelques sql. Je ne sais pas quoi faire, étant donné que localhost fonctionne bien. Des idées?

Et voici le pages_controller.rb:

class PagesController < ApplicationController 

    def home 
    @title = "Home" 
    if signed_in? 
     @micropost = Micropost.new 
     @feed_items = current_user.feed.paginate(:page => params[:page]) 
    end 
    end 

    def contact 
    @title = "Contact" 
    end 

    def about 
    @title = "About" 
    end 

    def help 
    @title = "Help" 
    end 
end

OK ... plus stupide question jamais. Je joue la carte de débutant .... j'ai oublié le "râteau d'heroku db: migrate". Tout va bien maintenant.
