Question

I have this code which if someone has a role "Server Developer" it is suppose to run the command which is to give someone the role "Jail" for the determent amount n the command but it doesn't work and gives no errors.

import discord
from discord.ext import commands
import ctx
import re
import time
from time import sleep
import asyncio

PREFIX = "$"
bot = commands.Bot(command_prefix=PREFIX, description="Hi")

@commands.has_role("Server Developer")
@bot.command()
async def court(ctx, user_mentioned: discord.Member, time: int):
    user_id = message.mentions[0].id
    user = message.mentions[0]
    role = discord.utils.get(message.guild.roles, name="Jail")
    await user_mentioned.add_roles(role)
    await ctx.send(
        f"sending <@{user_id}> to court!"
    )
    await asyncio.sleep(time)
    await user_mentioned.remove_roles(role)

bot.run(TOKNE_GOES_HERE)

Answer 1

You forgot to add @bot.command() on top of your command. Add it between @commands.has_role("Server Developer") and async def court(ctx, user_mentioned: discord.Member, time: int):

Do it like this:

import discord
from discord.ext import commands
import ctx
import re
import time
from time import sleep
import asyncio

PREFIX = "$"
bot = commands.Bot(command_prefix=PREFIX, description="Hi")

@commands.has_role("Server Developer")
@bot.command()
async def court(ctx, user_mentioned: discord.Member, time: int):
    user_id = ctx.message.mentions[0].id
    user = ctx.message.mentions[0]
    role = discord.utils.get(ctx.message.guild.roles, name="Jail")
    await user_mentioned.add_roles(role)
    await ctx.send(
        f"sending <@{user_id}> to court!"
    )
    await asyncio.sleep(time)
    await user_mentioned.remove_roles(role)

bot.run(TOKNE_GOES_HERE)

Using any check decorators like has_role or is_owner , doesn't make the function a command, so you would still have to add @commands.command() or @bot.command() :

@bot.command()
@commands.has_role("Server Developer")
async def court(ctx, user_mentioned: discord.Member, time: int):
    user_id = message.mentions[0].id
    user = message.mentions[0]
    role = discord.utils.get(message.guild.roles, name="Jail")
    await user_mentioned.add_roles(role)
    await ctx.send(
        f"sending <@{user_id}> to court!"
    )
    await asyncio.sleep(time)
    await user_mentioned.remove_roles(role)

bot.run(TOKNE_GOES_HERE)

Answer 3

you could try adding a check inside the command, something like this:

if not discord.utils.get(ctx.guild.roles, name="Server Developer") in ctx.user.roles:
    return
else:
    # do something
