Check if User has a certain role

Question

I have code in which you can type -giverole <user> <rolename> e.g. -giverole @Soup Board of Executives.
What I need now is a method that checks to see if the user typing the command has a certain role.

I have code that can give a role to someone:

@client.command(pass_context=True)
async def giverole(ctx, member: discord.Member, *, role: discord.Role):
    await client.add_roles(member, role)
    await client.say("The role '" + str(role) + "' has been given to " + member.mention + " .")

It should do await client.say() if the user has the right rank. If they don't, then it raises an error message.

Welcome to SO! Your Post sadly does not contain a question. – Sven-Eric Krüger Jan 23 '19 at 10:03 — Sven-Eric Krüger, Jan 23 '19 at 10:03

You can use discord.Member.roles to do something like

from discord.utils import get

@client.command(pass_context=True)
async def giverole(ctx, member: discord.Member, *, role: discord.Role):
  check_role = get(ctx.message.server.roles, name='Board of Executives')
  if check_role not in member.roles:
    await client.say(f"You don't have the role '{str(role)}'")
  else:
    await client.add_roles(member, role)
    await client.say(f"The role '{str(role)}' has been given to {member.mention}.")

You can use the commands.has_role check to determine whether or not the person invoking the command has a particular role:

@client.command(pass_context=True)
@has_role("Role Name")
async def giverole(ctx, member: discord.Member, *, role: discord.Role):
    await client.add_roles(member, role)
    await client.say(f"The role '{role}' has been given to {member.mention}.")

When someone without the role tries to invoke it, a commands.CheckFailure error will be raised. You can then handle that error if you want the bot to say something:

@giverole.error
async def giverole_error(error, ctx):
    if isinstance(error, CheckFailure):
        await client.send_message(ctx.message.channel, "You are lacking a required role")
    else:
        raise error

Thanks. My code raises an error. "has_role isn't defined". How would I fix this? – SoupChild REVAMPED Jan 23 '19 at 15:06
You need to import it: `from discord.ext.commands import has_role` – Patrick Haugh Jan 23 '19 at 15:08
Oh thanks. I thought of that however I put `from discord.ext import has_role`. Thanks a lot. I am a beginner to coding bots with Python using discord API. This really helps :) – SoupChild REVAMPED Jan 23 '19 at 15:10
Do you also know how to have multiple arguments for the `has_role`. For example, they could have the Board of Executives role or they can have the Moderation Manager role. – SoupChild REVAMPED Jan 23 '19 at 15:30
There is another check called [`has_any_role`](https://discordpy.readthedocs.io/en/rewrite/ext/commands/api.html#discord.ext.commands.has_any_role) that does that – Patrick Haugh Jan 23 '19 at 15:32
Thanks bud. This really helps. – SoupChild REVAMPED Jan 23 '19 at 15:34
Can you do `await client.say()` with a multiple line message. The message I want is: `Welcome to your Moderation Interview.` Q1) However line gaps between each part. – SoupChild REVAMPED Jan 23 '19 at 15:44
I think so. Try putting a newline literal `\n` wherever you want a line break: `"Welcome.\nHello"` – Patrick Haugh Jan 23 '19 at 16:03
