MongoEngine:关闭连接 [英] MongoEngine: Close connection

问题描述

我花了很长时间试图找到一个简单的示例，其中使用了MongoEngine并关闭了连接.终于找到答案并发布了我的代码.

I spent ages trying to find a simple example where MongoEngine was being used and a connection was being closed. Finally figured it out and posting my code.

推荐答案

我知道这是一个老问题，但是如果有人在搜索，我想我会给出一个替代答案.

I know this is an old question, but if anyone else is searching I figured I'd give an alternate answer.

close()实际上并没有从MongoEngine的连接列表中删除该连接.稍后尝试连接到其他数据库时，这会导致问题.

close() does not actually remove the connection from MongoEngine's connection list. This causes problems when trying to connect to a different database later on.

为解决这个问题，我使用了mongoengine.connection.disconnect(即使它未在__all__中列出).我的代码如下:

To solve this I used mongoengine.connection.disconnect (even though it's not listed in __all__). My code looks like this:

from mongoengine import connect
from mongoengine.connection import disconnect

db = connect(alias='some_alias')

{do stuff}

disconnect(alias='some_alias')

您也可以不使用别名，因为在连接和断开连接时，别名都将默认设置为默认".

You can also leave the alias out as it will default to 'default' in both connect and disconnect.
