грабли БД: мигрировать - mysql2 :: Ошибка: Таблица 'database_development.locations' не существует: SHOW FULL FIELDS FROM `locations`

Question

Rails 3.2.2

рубин 2.0.0

убунту 16,04

myssql сервер:

Версия: 5.7.12-0ubuntu1.1

Версия: 5.7.12-0ubuntu1

Версия: 5.7.11-0ubuntu6

бегают миграции, ошибки отображения: (смотрите ниже бревно)

Когда я иду в тузде консоли и выбрать все базы данных, в текущем списке есть мой дб.

Я попытался выполнить миграцию с другого компьютера, ubuntu 14.04, mysql server: 5.5.49, все работает без ошибок.

Как решить эту проблему? Благодарим Вас за заранее

Answer 1

Я думаю, что вы написали миграции для создания таблицы местоположений и добавление колонки в местах.

Ошибка переноса при добавлении таблицы в таблицу местоположений, как говорит журнал ошибок.

Шаг 1: Скопировать создание метки таблицы миграции таблицы времени (не добавлять метку времени столбца).

Шаг 2: Найдите его в таблице schema_migrations и удалите из него эту запись.

rake db:migrate чем
