Ошибка генерации пользовательского генератора

-1

Я строю свое первое приложение для рельсов. Когда я бегу rails server и перейти на главную страницу, я получаю эту ошибку подсветки линии 2:Ошибка генерации пользовательского генератора

ActiveRecord :: PendingMigrationError

Миграции в ожидании. Чтобы устранить эту проблему, выполните следующую команду: бен/грабли БД: мигрировать RAILS_ENV = развитие

Извлеченные источник (около линии № 392):
def check_pending!(connection = Base.connection) 
    raise ActiveRecord::PendingMigrationError if ActiveRecord::Migrator.needs_migration?(connection) 
end 

def load_schema_if_pending! 

Когда я бегу rake db:migrate RAILS_ENV=development я получаю эту ошибку

Я удалил все в дб/мигрировать, а затем побежал rails g devise user в nd rake db:migrate еще раз. Который возвращает эту ошибку

(See full trace by running task with --trace)

Это вызвано двумя devise_for :users линий в routes.rb. Я удаляю одну строку, запускаю rake db:migrate и снова получаю первую ошибку.

вставьте ваш ** маршрут.rb ** файл. –

проверить эту ссылку http://stackoverflow.com/questions/10301794/difference-between-rake-dbmigrate-dbreset-and-dbschemaload –

@AmitSharma это мои маршруты.rb https://gist.github.com/unident77/ 12984b466a1712a3997b Я пробовал 'rake db: drop', а затем добавлял пользователя и мигрировал, но получаю ту же самую массивную ошибку. – unident77

Возможно, вы случайно испортили свои миграции. Попробуйте удалить db вручную, затем убедитесь, что в ваших миграциях нет никаких ошибок, а затем снова запускайте команды rake db ..... Если в ваших миграциях произошла ошибка, удалите ее или исправьте вручную.

Удалив db вручную, вы имеете в виду использование' rake db: drop'? – unident77
