Heroku App Crash

Question

J'ai testé mon application Rails 3 localement plusieurs fois et j'ai finalement été déployée sur Heroku. Tout a bien fonctionné pendant un certain temps, toutes les pages se chargeaient et j'ai commencé à recevoir une page d'erreur indiquant que l'application s'était écrasée. Je vérifie mes journaux et voici la sortie:

Quelqu'un at-il une idée de ce qui ne va pas? Merci d'avance!

Il ressemble à vous pourriez avoir oublié de migrer après avoir poussé le nouveau code. Pour effectuer la migration de DB de votre application sur Heroku, exécutez:

heroku rake db:migrate
