如何从Rails中的特定数据库断开连接？ [英] How to disconnect from a particular database in rails?

问题描述

我使用此代码段连接到另一个数据库

I use this snippet to connect to another db

ActiveRecord::Base.establish_connection....

但我不知道在不需要此连接后如何删除它。

but I don't know how to delete this connection after it is not needed.

推荐答案

您可以调用删除连接

old_connection = ActiveRecord::Base.remove_connection

如果您已完成操作像下面的（有分配）

If you have done something like the following (where there is an assignment)

new_connection = ActiveRecord::Base.establish_connection(...)

这可以传递给 remove_connection

old_connection = ActiveRecord::Base.remove_connection(new_connection)

您可以在源代码。
