rake db: create получает «undefined method» [] '"

Question

При настройке приложения rails, которое я написал давно, я бросил базу данных, чтобы начать миграцию.

Упс - теперь даже базовый db: настройка не работает!

Если я правильно помню, один делает

$ RAILS_ENV=development bundle exec rake db:setup 
$ RAILS_ENV=development bundle exec rake db:migrate 

Я думаю, что проблема не моя база данных больше не распознается рейка/рельсы. Любые догадки о том, почему?

Моя база данных.yml не изменилась недавно!

test: 
    adapter: postgresql 
    database: argotifier_test 
    username: argotifier 
    password: start123 
    host:  localhost 
    pool:  5 

Вот след, когда я бегу на грабли задачи:

$ RAILS_ENV=test bundle exec rake db:setup --trace 
** Invoke db:setup (first_time) 
** Invoke db:create (first_time) 
** Invoke db:load_config (first_time) 
** Invoke rails_env (first_time) 
** Execute rails_env 
** Execute db:load_config 
** Execute db:create

Answer 1

Вы должны запустить rake db:test:prepare для тестовой базы данных.

Проверить наличие this.
