Mi intención es crear un canal para los mensajes de bienvenida de inmediato cuando el robot se une y para ser capaz de cambiar mediante el comando asignado. Este es mi código:
import discord
from discord.ext import commands
import json
def get_welcomechannel(client, message,):
with open('welcomechannel.json', 'r') as f:
welcomechannel = json.load(f)
return welcomechannel[str(message.guild.id)]
@client.event
async def on_guild_join(guild):
general = find(lambda x: x.name == 'general', guild.text_channels)
if general and general.permissions_for(guild.me).send_messages:
await general.send(f'Hello {guild.name}! My name is {client.user.name} and my prefix is ``?``! run ``?help`` to begin using me!')
with open('prefixes.json', 'r') as f:
prefixes = json.load(f)
prefixes[str(guild.id)] = "?"
with open ('prefixes.json', 'w') as f:
json.dump(prefixes, f, indent=4)
with open('welcomechannel.json', 'r') as f:
welcomechannel = json.load(f)
welcomechannel[str(guild.id)] = "general"
with open ('prefixes.json', 'w') as f:
json.dump(prefixes, f, indent=4)
@client.event
async def on_guild_remove(guild):
with open('prefixes.json', 'r') as f:
prefixes = json.load(f)
prefixes.pop(str(guild.id))
with open ('prefixes.json', 'w') as f:
json.dump(prefixes, f, indent=4)
with open('welcomechannel.json', 'r') as f:
welcomechannel = json.load(f)
welcomechannel.pop(str(guild.id))
with open ('welcomechannel.json', 'w') as f:
json.dump(welcomechannel, f, indent=4)
print(f"{guild.name} kicked me!")
#rest of code here...
@client.command(name="changewelcomechannel")
async def changewelcomechannel(ctx, welcomechannel):
with open('welcomechannel.json', 'r') as f:
welcomechannel = json.load(f)
welcomechannel[str(ctx.guild.id)] = welcomechannel
with open ('welcomechannel.json', 'w') as f:
json.dump(welcomechannel, f, indent=4)
await ctx.send(f"Welcome channel is now **{welcomechannel}**!"
pero me da este error:
Ignoring exception in command changewelcomechannel:

Yo no contó con el código de error localmente de modo que tuve que copiar y pegar el heroku código de error que pude encontrar.
He utilizado la misma estructura en otro de los comandos y funcionó muy bien. Yo no soy tan experimentado con el uso de json módulo en python, por lo que si alguien puede ayudar, sería impresionante. Muchas gracias
edit: finalmente me di cuenta de lo que hice mal, se suponía que yo uso otra variable en
welcomechannel[str(ctx.guild.id)] = welcomechannel# this is supposed to be the new variable#
