Ошибка миграции Heroku

Question

В настоящее время я нажимаю рельсы 3.2 с рубином 2.0 на герою. Я успешно вытолкнул код на новый сервер heroku, и теперь я пытаюсь выполнить миграцию БД, а затем засеваю его.

Когда я запускаю команду

$ heroku run rake:db:migrate 

Я получаю ошибку:

Running `rake db:migrate` attached to terminal... up, run.8854

это то, что имеет отношение к Завещания? Не уверен, что делать здесь.

Кроме того, некоторые респонденты спрашивали, если у меня есть таблица пользователей: < .br>

create_table "users", :force => true do |t| 
    t.string "name" 
    t.datetime "created_at",        :null => false 
    t.datetime "updated_at",        :null => false 
    t.string "email",     :default => "", :null => false 
    t.string "encrypted_password",  :default => "", :null => false 
    t.string "reset_password_token" 
    t.datetime "reset_password_sent_at" 
    t.datetime "remember_created_at" 
    t.integer "sign_in_count",   :default => 0 
    t.datetime "current_sign_in_at" 
    t.datetime "last_sign_in_at" 
    t.string "current_sign_in_ip" 
    t.string "last_sign_in_ip" 
    t.string "provider" 
    t.string "uid" 
    end 

Answer 1

ошибка означает, что вы пытаетесь изменить таблицу users, но таблица не существует.

Вы должны были создать таблицу как часть другой миграции или проверить документацию по установке. Я уверен, что есть инструкции по созданию необходимой таблицы вместо ее изменения.

Я дал быстрый взгляд at the documentation, и я считаю, что процедура описана в разделе «Начало работы» по команде

rails generate devise MODEL
