强制DataMapper与PostgreSQL断开连接 [英] Force DataMapper to disconnect from postgresql

问题描述

我有一个测试，该测试正在postgresql中创建和销毁许多数据库。为了能够删除数据库，我需要告诉DataMapper断开连接。我似乎找不到任何有关此操作的文档。

I have a test that is creating and destroying a number of databases in postgresql. In order to be able to drop a database I need to tell DataMapper to disconnect. I can't seem to find any documentation on how to do that.

DataMapper :: Adapters :: PostgresAdapter上有一个close_connection方法，但是它是受保护的，并且需要我似乎无法获得的连接对象。

There is a close_connection method on DataMapper::Adapters::PostgresAdapter but it is protected and requires a connection object that I can't seem to get.

这甚至可能吗？

推荐答案

DataObjects :: Pooling.pools.each {| pool | pool.dispose} 似乎可以工作，只要您一次只打开一个连接即可。

DataObjects::Pooling.pools.each {|pool| pool.dispose} seems to work as long as you have only one connection open at a time.
