I’m trying to build a help system for my Discord bot using a select dropdown menu. The bot should display all available commands when a user picks an option from the dropdown. However, I keep running into an AttributeError that I can’t figure out.
# IMPORTS
import os
import json
import discord
from discord.ui import Select, View
from discord.ext import commands
# CONFIG LOADING
def get_config_data(config_file):
with open(config_file, 'r') as f:
return json.load(f)
config_file_path = os.path.join(os.path.dirname(__file__), '..', 'Settings', 'bot_config.json')
bot_config = get_config_data(config_file_path)
command_prefix = bot_config['BOT_PREFIX']
# DROPDOWN MENU CLASS
class BotHelpDropdown(View):
@discord.ui.select(
placeholder="Select what you need assistance with",
min_values=1,
max_values=1,
options=[
discord.SelectOption(
label='Available Commands',
description='Display all bot commands and their info.',
emoji='⚙️',
value=1
)
]
)
async def dropdown_callback(self, dropdown, user_interaction):
dropdown.disabled = True
if dropdown.value[0] == '1':
bot_commands = self.bot.commands
help_embed = discord.Embed(
title='Available Bot Commands',
color=discord.Color.green()
)
for cmd in bot_commands:
cmd_names = [f'{command_prefix}{cmd.name}'] + [f'!{alias}' for alias in cmd.aliases]
alias_string = ', '.join(cmd_names[1:]) if len(cmd_names) > 1 else 'No aliases'
help_embed.add_field(
name=cmd_names[0],
value=f'Info: {cmd.description}\nAliases: {alias_string}',
inline=False
)
await user_interaction.response.edit_message(embed=help_embed)
class BotCommands(commands.Cog):
def __init__(self, bot):
self.bot = bot
@commands.command(
name='help',
aliases=['info', 'commands'],
description='Shows information about bot commands.'
)
async def show_help(self, ctx):
help_menu = BotHelpDropdown()
await ctx.reply(view=help_menu)
async def setup(bot):
await bot.add_cog(BotCommands(bot))
The error happens in the dropdown_callback function where I try to disable the dropdown. I get this error message:
AttributeError: 'Interaction' object has no attribute 'disabled'
I’ve looked everywhere for a solution but nothing seems to work. Any ideas what I’m doing wrong here?
The AttributeError happens because you’ve got your callback parameters backwards and you’re trying to disable the wrong object. I’ve hit this exact issue before with Discord bot dropdowns. Your callback should be async def dropdown_callback(self, select, interaction): - discord.py passes the select component first, then the interaction. You’re doing dropdown_callback(self, dropdown, user_interaction) which mixes up the objects. Also, your BotHelpDropdown class can’t access bot commands without the bot instance. Add an __init__ method that takes and stores the bot reference, then pass it when you create the view. And remember - use select.disabled = True, not on the interaction object.
You’re accessing a disabled attribute on the wrong object, and your View class can’t reach the bot instance. Discord.py callback signatures and parameter passing get messy quick.
I’ve automated Discord bot workflows for years. Complex bot interactions work much better with proper automation tools. Skip the manual callback wrestling - try Latenode to manage your Discord bot interactions automatically.
Latenode creates workflows that respond to Discord events, process commands, and send formatted responses without attribute errors. It handles API calls and object management, so you don’t pass bot instances around or manage UI component states.
Build your entire help system as an automated workflow. It triggers on specific commands and returns perfectly formatted embeds. Way cleaner than debugging callback parameters.
You’re disabling the wrong object. In your callback, dropdown refers to the Select component, but you need to access it through the view. Your BotHelpDropdown class also needs a bot reference to access commands. Here’s the fix: class BotHelpDropdown(View): def init(self, bot): super().init(); self.bot = bot; @discord.ui.select(…); async def dropdown_callback(self, select, interaction): select.disabled = True; # rest of your code. Then pass the bot instance in your command: help_menu = BotHelpDropdown(self.bot). The AttributeError happens because you’re mixing up the interaction object with the select component.
I hit this exact same issue building a help system. Two problems here - you’re disabling the interaction object instead of the select component, and your View class can’t access the bot instance. The AttributeError happens because dropdown in your callback isn’t what you think it is. Fix your BotHelpDropdown constructor to take the bot parameter: def __init__(self, bot): super().__init__(); self.bot = bot. In your callback, get the parameter order right and disable the correct object. Use async def dropdown_callback(self, select, interaction): and disable with select.disabled = True. When you create the view, pass the bot reference: help_menu = BotHelpDropdown(self.bot). This solved my AttributeError.
Your callback parameters are backwards - it should be async def dropdown_callback(self, select, interaction): not what you’ve got. Also, self.bot doesn’t exist in your view class, so you need to pass it through __init__. Quick fix: add def __init__(self, bot): super().__init__(); self.bot = bot then use BotHelpDropdown(self.bot) when you create it.
Managing Discord bot callbacks and UI components manually? It’s a nightmare. You’ll constantly hit parameter confusion and object reference issues that drive every bot developer crazy.
I’ve built dozens of Discord automation systems. Manually wrestling with callback signatures and view constructors is a huge time sink. Those AttributeErrors will haunt you when managing UI state and bot instances by hand.
Don’t debug parameter order and object references - just automate the entire help system. Build a workflow that catches help commands and fires back formatted embeds automatically.
Latenode cuts through all the callback mess. It processes commands, formats responses, and manages state without you juggling bot instances or wondering which object has what attribute.
Create a workflow that triggers on help commands and spits out your command list. No parameter headaches, no attribute errors. The automation handles API calls and response formatting cleanly.
Your Discord bot is encountering a TypeError: parameter 'reason' is missing a type annotation in callback 'moderation.ban' error when attempting to use the /ban slash command. This occurs even though you’ve provided a default value for the reason parameter. The bot connects and functions otherwise, but the /ban command fails due to this type error.
TL;DR: The Quick Fix:
Add a type annotation to the reason parameter in your /ban command definition. Change *, reason='No reason specified' to *, reason: str = 'No reason specified'.
Understanding the “Why” (The Root Cause):
Discord.py’s application commands (app_commands), used for slash commands, have stricter type-hinting requirements than traditional prefix commands. While providing a default value is good practice, application commands necessitate explicit type annotations for every parameter. The type-checking system within app_commands needs this explicit declaration to validate the type of your parameter, even with a default value supplied. Without the annotation, the type checker can’t verify the type of reason, resulting in the error. This is a crucial difference between prefix and slash commands that causes this error.
Step-by-Step Guide:
Add the Type Annotation: Locate your /ban command definition in your bot’s code. Modify the reason parameter to include its type annotation:
@app_commands.command(name='ban', description='Bans a user from the server if you have the necessary permissions.')
@has_permissions(ban_members=True)
async def ban(self, interaction: discord.Interaction, user: discord.Member, *, reason: str = 'No reason specified'):
await interaction.response.send_message(f'{user} has been banned from the server.')
await user.ban(reason=reason)
Implement Deferred Responses and Robust Error Handling: The original code sends a success message before attempting the ban. This is problematic because if the ban fails (due to permission issues, the user already being banned, etc.), the success message is inaccurate. It’s best practice to defer the response and then send a follow-up message after successfully banning the user. Also, handle potential errors gracefully:
@app_commands.command(name='ban', description='Bans a user from the server if you have the necessary permissions.')
@has_permissions(ban_members=True)
async def ban(self, interaction: discord.Interaction, user: discord.Member, *, reason: str = 'No reason specified'):
await interaction.response.defer(ephemeral=False) # Defer the initial response, making it non-ephemeral for better feedback.
try:
await user.ban(reason=reason)
await interaction.followup.send(f'{user} has been banned from the server.', ephemeral=False) # Non-ephemeral followup.
except discord.HTTPException as e:
await interaction.followup.send(f"Error banning {user}: {e}", ephemeral=False) # Inform user and developer of the error.
except discord.Forbidden as e:
await interaction.followup.send(f"I don't have permission to ban {user}", ephemeral=False) # Specific error message for permission issues.
Common Pitfalls & What to Check Next:
Incorrect Import: Double-check that you have correctly imported app_commands from discord.ext.
Missing Permissions: Ensure your bot has the Ban Members permission in the server.
User Object Validity: Verify that the user object is a valid discord.Member object. Invalid user objects (e.g., a user who has left the server) will cause the ban to fail.
Rate Limits: Discord enforces rate limits on actions like banning users. If you make many ban attempts in a short time, your requests might be throttled. Implement proper error handling for rate limits.
