我的db配置

development:
  adapter: mysql
  database: selvista
  username: root
  pool: 5
  timeout: 5000

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: mysql
  database: selvista_test
  username: root
  pool: 5
  timeout: 5000

production:
  adapter: mysql
  database: selvista_prod
  username: root
  pool: 5
  timeout: 5000

我的适配器应该是mysql2吗？

Answer 1

您可以尝试将mysql2放在database.yml中的适配器行上。

development:
  adapter: mysql2
  database: selvista
  username: root
  pool: 5
  timeout: 5000

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: mysql2
  database: selvista_test
  username: root
  pool: 5
  timeout: 5000

production:
  adapter: mysql2
  database: selvista_prod
  username: root
  pool: 5
  timeout: 5000
