Anziche’ upgradare la vecchia app l’ho ricreata ex novo con rails 3.1. Lancio rake db:migrate e: # == DeviseCreateUsers: migrating # == DeviseCreateUsers: migrated (0.0000s) rake aborted! An error has occurred, this and all later migrations canceled: private method `split’ called for #Arel::InsertManager:0x48fa3b39 Come inizio non c’e’ male, se non funzionano le migration sono bloccato. ---
