RoR дб: мигрировать не работает

Я использую свою локальную среду на Mac OS X с Rails 4.RoR дб: мигрировать не работает

При попытке запустить мою миграцию, она не работает.

я получаю следующий результат:

*******-C02MGBVJFD57:myapp *************$ bundle exec rake db:migrate 
Your Gemfile lists the gem faker (>= 0) more than once. 
You should probably keep only one of them. 
While it's not a problem now, it could cause errors if you change the version of just one of them later.

Любая идея, что это неправильно?

EDIT: Схема для пользователей таблицы ниже:

create_table "users", force: true do |t| 
    t.string "name" 
    t.string "email" 
    t.datetime "created_at" 
    t.datetime "updated_at" 
    t.string "password_digest" 
    t.string "remember_digest" 
    end

Пользователи Миграция:

class CreateUsers < ActiveRecord::Migration 
    def change 
    create_table :users do |t| 
     t.string :name 
     t.string :email 
     t.string :password_digest 

     t.timestamps 
    end 
    end 
end 

class AddPasswordDigestToUsers < ActiveRecord::Migration 
    def change 
    add_column :users, :password_digest, :string

В этой строке в ваших журналах указано, что столбец уже существует: 'ActiveRecord :: StatementInvalid: Mysql2 :: Ошибка: Дублировать имя столбца 'password_digest': ALTER TABLE 'user' ADD 'password_digest' varchar (255)' - Посмотрите ваш файл 'db/schema.rb', чтобы узнать, существует ли уже столбец' password_digest' (более надежная проверка будет заключаться в непосредственном изучении базы данных mysql). – richsinn

Так это выглядит как таблица пользователей переносится хорошо, но работает ДБ: семя, я получаю: У вас есть 2 ожидающие миграции: 20140815221246 AddPasswordDigestToUsers 20141114000137 AddRememberDigestToUsers Run 'грабли БД: migrate', чтобы обновить базу данных и повторите попытку. – user1072337

Я добавил часть схемы, нет дубликата password_digest – user1072337

Проблема происходит потому, что в вашей CreateUsers миграции, вы уже создает users таблицу с столбец password_digest, подтвержденный этой линией:

t.string :password_digest

Тогда в вашей AddPasswordDigestToUsers миграции, вы пытаетесь добавить колонку с тем же именем в users таблицы:

add_column :users, :password_digest, :string

Это где миграция потерпела неудачу с ошибкой Mysql2::Error: Duplicate column name 'password_digest'.

Возможно, вам нужен файл AddPasswordDigestToUsers? Это не похоже на то, что вы уже добавили столбец в миграцию CreateUsers.

Я думаю, вы можете просто удалить файл миграции AddPasswordDigestToUsers и попробовать перезагрузить bundle exec rake db:migrate.

Это была проблема, спасибо. – user1072337

Прохладный. Запуск 'rake db: seed' должен теперь работать. – richsinn
