python - 如何停止“ValueError：tortoise.backends.sqlite.client.SqliteClient 对象是在不同的上下文中创建的”？

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，但我不断收到以下错误：

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

我正在创建我的交易，在 discord ext.commands 命令中

        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)

我还尝试使用函数开始我的事务，这会导致相同的错误。我的问题是：这是什么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意思，我如何让它消失？

解决方案

我已经弄清楚我的问题了！在查看我的代码并查看可能干扰的内容时，我发现我正在使用nest_asyncio，我认为这不是问题

删除模块后，代码现在可以工作了
