如何停止“ ValueError：tortoise.backends.sqlite.client.SqliteClient对象是在其他上下文中创建的”？ [英] How do I stop "ValueError: tortoise.backends.sqlite.client.SqliteClient object was created in a different Context"?

问题描述

我正在编写一个不和谐的机器人，并使用乌龟Orm来存储数据。我需要使用事务，但是我不断收到以下错误：

I'm writing a discord bot and using tortoise orm to store data. I need to use transactions, but I continually get the following error:

Full type of the error is <class 'discord.ext.commands.errors.CommandInvokeError'>

我正在创建我的交易，例如因此，在不协调的ext.commands命令中

I'm creating my transactions like so, in a discord ext.commands command

        async with tortoise.transactions.in_transaction() as guild_creation:
            default_game_settings = database.guild.GameDefaults()
            await default_game_settings.save(using_db=guild_creation)
            settings = database.guild.GuildSettings()
            await settings.save(using_db=guild_creation)
            guild = database.guild.Guild(
                guild_id=ctx.guild.id,
                agreed_at=datetime.datetime.now(),
                agreed_by=ctx.author.id,
                default_settings=default_game_settings,
                settings=settings,
            )
            await guild.save(using_db=guild_creation)

我也试图开始我的交易带有功能的部分，会导致相同的错误。我的问题是： ValueError是什么：< Token var =< ContextVar name ='default'default =< tortoise.backends.sqlite.client.SqliteClient object at 0x7f52ef5080d0>在0x7f52ef362630>在0x7f52dd636c80>是在不同的上下文中创建的是什么意思，如何删除它？

I've also tried to start my transactions with a function, which results in the same error. My question is: what does ValueError: <Token var=<ContextVar name='default' default=<tortoise.backends.sqlite.client.SqliteClient object at 0x7f52ef5080d0> at 0x7f52ef362630> at 0x7f52dd636c80> was created in a different Context mean, and how do I get it to go away?

推荐答案

我已经解决了我的问题！
在遍历我的代码并查看可能造成的干扰时，我发现我正在使用 nest_asyncio ，我认为这不是问题

I've figured out my issue! While going through my code and seeing what could be interfering I found that I was using nest_asyncio, which I didn't believe to be an issue

已删除模块，代码现在可以正常工作

Having removed the module, the code now works
