英文:
I want to send a list of users who reacted to my message but the list always shows empty
问题
我查了一下，看到有人这样做，但它总是返回一个空列表
```python
@bot.command()
async def spinthewheel(ctx,msg:discord.Message=None):
guild=ctx.guild
if msg==None:
em=discord.Embed(title="SPIN THE WHEEL!!", description="React to this message with ⚡ to enter!",color=discord.Color.from_str('#ff00ff'))
msg=await ctx.send(embed=em)
await msg.add_reaction('⚡')
else:
await msg.add_reaction('⚡')
await ctx.send("Reaction has been added",delete_after=10)
await asyncio.sleep(5)
users = list()
for reaction in msg.reactions:
if reaction.emoji == '⚡':
async for user in reaction.users():
if user != bot.user:
users.append(user.name)
user_list="\n".join(user.name for user in users)
await ctx.send(f"users: {user_list}")
我也尝试了这个，但结果一样
users = [user async for user in reaction.users()]
你能告诉我如何修复这个问题吗？谢谢 <3

I searched it up and saw someone do it like this but it always returns an empty list
@bot.command()
async def spinthewheel(ctx,msg:discord.Message=None):
guild=ctx.guild
if msg==None:
em=discord.Embed(title="SPIN THE WHEEL!!", description="React to this message with ⚡ to enter!",color=discord.Color.from_str('#ff00ff'))
msg=await ctx.send(embed=em)
await msg.add_reaction('⚡')
else:
await msg.add_reaction('⚡')
await ctx.send("Reaction has been added",delete_after=10)
await asyncio.sleep(5)
users = list()
for reaction in msg.reactions:
if reaction.emoji == '⚡':
async for user in reaction.users():
if user != bot.user:
users.append(user.name)
user_list="\n".join(user.name for user in users)
await ctx.send(f"users: {user_list}")
I tried using this one too but same results
users = [user async for user in reaction.users()]
Can you pls tell me how to fix this? Thanks <3

**得分**: 1
问题在于`msg.reactions`为空 - 这是因为它是在创建时的消息表示，并且自那时以来没有更新过与反应相关的信息。这很容易通过以下方式来修复：
```python
msg = await msg.fetch()
这将从频道中重新获取消息。只需将它放在asyncio.sleep之后，然后再循环遍历反应之前。
英文:
The issue is that msg.reactions is empty - this is because it's the message representation at the time it was created and hasn't been updated since with the reaction information. This is easily fixable with a:
msg = await msg.fetch()
This will fetch the message anew from the channel. Just put it after your asyncio.sleep and before you loop over the reactions.
