問題描述

所以我正在為我的服務器開發帶有 discord.py 的不和諧機器人.我正在使用replit的數據庫系統.當我嘗試將我的類 Player 的實例添加到該數據庫的鍵時，它說:

So I'm developing discord bot with discord.py for my server. I'm using replit's database system. When I try to add instance of my class Player to key of that database it says:

Traceback (most recent call last):
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "main.py", line 36, in jointothefun
    db[f"{context.message.author.id}"] = p
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/replit/database/database.py", line 486, in __setitem__
    self.set(key, value)
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/replit/database/database.py", line 495, in set
    self.set_raw(key, _dumps(value))
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/replit/database/database.py", line 56, in dumps
    return json.dumps(val, separators=(",", ":"), cls=DBJSONEncoder)
  File "/usr/lib/python3.8/json/__init__.py", line 234, in dumps
    return cls(
  File "/usr/lib/python3.8/json/encoder.py", line 199, in encode
    chunks = self.iterencode(o, _one_shot=True)
  File "/usr/lib/python3.8/json/encoder.py", line 257, in iterencode
    return _iterencode(o, 0)
ValueError: Circular reference detected

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/bot.py", line 902, in invoke
    await ctx.command.invoke(ctx)
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/core.py", line 864, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: ValueError: Circular reference detected

我不知道為什么它根本不起作用.有人可以幫忙嗎?

I have no idea why it's not working at all. Some one could help?

哦，還有源代碼(是的，我知道我正在制作意大利面條代碼)

Oh and source code (yes i know i'm making spaghetti code)

如果有人能幫助我，我將不勝感激:)

I would be so grateful if someone would help me :)

推薦答案

如回答 here，值 的 repli 數據庫必須是 JSON 可序列化的.這意味著，您必須(很可能)傳遞一個 dict 而不是類對象，但是您將無法使用該對象的函數.

as answered here, the values of replit's database must be JSON-serializable. This means, you'd have to pass (most likely) a dict instead of a class object, but then you won't be able to use the object's functions.
