ruby-on-rails – database.yml的所有可能键

我刚刚发现在 database.yml文件中可以使用reconnect：true配置选项.
还有哪些其他可能的配置选项？所有选项都有完整的参考吗？

已知的关键示例：

default: &default
  adapter: MysqL2
  encoding: utf8
  pool: 5
  username: foo
  password: bar
  reconnect: true
  socket: /var/sock/thing.sock

development:
  <<: *default
  database: app_development

解决方法

我认为没有任何地方可以列出它们,但我检查了ActiveRecord的ConnectionAdapaters.请记住,选项会更改您使用的数据库,但这是在MysqL连接适配器中列出的.
