When I create a button and handle the callback or send a message and await a reaction in discord with my python bot, this seems to be limited in time. Sometimes after ~ 1hour, the bot doesn't register reactions anymore. For sure once I restart the bot, the connection is lost and it won't register the interaction anymore.
However, I have seen bots in discord that always react to a button, no matter how long ago that button was created. Is there a way to achieve this? Do I have to periodically "reconnect" the bot to the buttons it created?
Simple example:
class ButtonView(disnake.ui.View):
def __init__(self):
super().__init__(timeout=None)
@disnake.ui.button(label="Hi", style=ButtonStyle.red)
async def first_button(
self, button: disnake.ui.Button, interaction: disnake.MessageInteraction
):
await interaction.response.send_message("Button clicked.")
class Test(commands.Cog):
def __init__(self, bot: commands.Bot):
self.bot = bot
@commands.slash_command()
async def test(self, inter):
await inter.send("Button!", view=ButtonView())
-> In this example the bot won't react to the button click anymore after some time has passed or I restarted the bot.
You can do like this :
import disnake
from disnake.ext import commands
# Define a simple View that persists between bot restarts
# In order a view to persist between restarts it needs to meet the following conditions:
# 1) The timeout of the View has to be set to None
# 2) Every item in the View has to have a custom_id set
# It is recommended that the custom_id be sufficiently unique to
# prevent conflicts with other buttons the bot sends.
# For this example the custom_id is prefixed with the name of the bot.
# Note that custom_ids can only be up to 100 characters long.
class PersistentView(disnake.ui.View):
def __init__(self):
super().__init__(timeout=None)
@disnake.ui.button(
label="Green", style=disnake.ButtonStyle.green, custom_id="persistent_view:green"
)
async def green(self, button: disnake.ui.Button, interaction: disnake.MessageInteraction):
await interaction.response.send_message("This is green.", ephemeral=True)
@disnake.ui.button(label="Red", style=disnake.ButtonStyle.red, custom_id="persistent_view:red")
async def red(self, button: disnake.ui.Button, interaction: disnake.MessageInteraction):
await interaction.response.send_message("This is red.", ephemeral=True)
@disnake.ui.button(
label="Grey", style=disnake.ButtonStyle.grey, custom_id="persistent_view:grey"
)
async def grey(self, button: disnake.ui.Button, interaction: disnake.MessageInteraction):
await interaction.response.send_message("This is grey.", ephemeral=True)
class PersistentViewBot(commands.Bot):
def __init__(self):
super().__init__(command_prefix=commands.when_mentioned)
self.persistent_views_added = False
async def on_ready(self):
if not self.persistent_views_added:
# Register the persistent view for listening here.
# Note that this does not send the view to any message.
# In order to do this you need to first send a message with the View, which is shown below.
# If you have the message_id you can also pass it as a keyword argument, but for this example
# we don't have one.
self.add_view(PersistentView())
self.persistent_views_added = True
print(f"Logged in as {self.user} (ID: {self.user.id})")
print("------")
bot = PersistentViewBot()
@bot.command()
@commands.is_owner()
async def prepare(ctx: commands.Context):
"""Starts a persistent view."""
# In order for a persistent view to be listened to, it needs to be sent to an actual message.
# Call this method once just to store it somewhere.
# In a more complicated program you might fetch the message_id from a database for use later.
# However this is outside of the scope of this simple example.
await ctx.send("What's your favourite colour?", view=PersistentView())
bot.run("token")
