Ich benutze Active Admin Gem für meine kleine Anwendung basierend auf Quiz. Aber wenn ich Rake db ausführen: migrieren gibt es mir einen Fehler. Es folgt der Spur des Befehls:undefined Methode `database_authenticatable 'für # <ActiveRecord :: ConnectionAdapters :: TableDefinition: 0x9dee690>
$ rake db:migrate RAILS_ENV=production --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config
** Execute db:migrate
== DeviseCreateAdminUsers: migrating =========================================
-- create_table(:admin_users)
rake aborted!
An error has occurred, all later migrations canceled:
undefined method `database_authenticatable' for #<ActiveRecord::ConnectionAdapters::TableDefinition:0x9dee690>

I für die oben Problem gesucht und bekam this, aber das hat mir nicht geholfen. Überall fand ich diese Lösung nur. Ist jemand schon einmal auf dieses Problem gestoßen, wenn ja, was haben Sie getan, um es anzugehen? Jede Hilfe dazu wird geschätzt. Danke
Danke Mann. Hab das gemacht. Das Problem war, dass die Migrationsdatei Spaltennamen statt Methodennamen hatte. – lucifer
könnten Sie bitte den Migrationscode in diese Antworten einfügen. – baash05
