什么是database.yml的所有可能键 [英] What are all possible keys for database.yml

问题描述

我刚刚发现 database.yml 文件中的 reconnect：true 配置选项是可能的。
还有哪些其他可能的配置选项？是否有所有选项的完整参考？

I've just discovered that the reconnect: true configuration option is possible in the database.yml file. What other possible configuration options are there? Is there a complete reference for all options?

已知关键示例：

default: &default
  adapter: mysql2
  encoding: utf8
  pool: 5
  username: foo
  password: bar
  reconnect: true
  socket: /var/sock/thing.sock

development:
  <<: *default
  database: app_development

推荐答案

我认为没有任何地方可以列出它们，但是我检查了ActiveRecord的ConnectionAdapaters。请记住，选项会更改您使用的数据库，但这已在MySQL连接适配器中列出。

I don't think there is any place that just lists them but I checked the ActiveRecord's ConnectionAdapaters. Keep in mind that options change which database you use, but this was listed within the MySQL connection adapter.
