discord.py：循环通过成员列表不起作用

Question

@bot.command()
async def start(ctx):
     CUSTOMER_IDS = []

     for member in ctx.guild.members:
          for role in member.roles: 
               if role.id == CUSTOMER_ROLE_ID: 
                    print(f'{member} has the customer role!')
                    CUSTOMER_IDS.append(str(member))

               else:
                    print(f'{member} does not have the customer role!') 

     print(f'\n{CUSTOMER_IDS}')
     await ctx.reply(f'List: `{CUSTOMER_IDS}`')

its supposed to go thru a loop of the guild's members and validate wether they have a role or not. I tested this on my server with about 500 members (300+ have the role) and it only returned 1 member and 2 checks of the bot itself.

I feel what is most likely happening in this scenario is that discord.py rightfully doesn't keep all of that data cached. Instead what you'll need to do is make the REST API requests for what you are trying to do. So in this case, you could try the following:

guild = bot.get_guild(ctx.guild.id)

# It is far more efficient to get the members from the role rather
# the role from the members.
role = guild.get_role(CUSTOMER_ROLE_ID)
customers = role.members

# from here you have a list with all the member objects of people with the role
# so you can do as you wish with them from there, for example:

print(f"Customer ID's: {[m.id for m in customers]}")
