How do I make a command in discord.py usable once per hour/day/year?

Question

Python

Here is the command

@client.command()
async def beg(ctx):
    denga = random.randint(0,100)
    user = ctx.author
    hour=None
    mbalance=collection.find_one({"_id":user.id})["balance"]
    if hour==None:
        collection.update_one({"_id":user.id},
        {"$set": {"balance":mbalance+denga }})
        await ctx.send(embed=discord.Embed(
        description=f'**Копошась на полу вы нашли {denga} монет**'))
    else:
        await ctx.send("Вы можете использовать эту команду лишь раз в час!")

how to make it so that when re-used in less than an hour, the bot sends a message that you need to wait?

Answer 1

Use a decorator

@commands.cooldown(rate, per, type=<BucketType.default: 0>)

@client.command()
@commands.cooldown(1, 60, commands.BucketType.user)  # Один раз в 60 секунд на пользователя (глобально)
async def cmd(ctx, ...):
    ...

To send a message when a command is called in cooldown, you need to handle the commands.CommandOnCooldown exception :

@client.listen("on_command_error")
async def cooldown_message(ctx, error):
    if isinstance(error, commands.CommandOnCooldown):
        await ctx.send(f"{ctx.command.qualified_name} можно использовать только {error.cooldown.rate} раз в {error.cooldown.per} секунд. Попробуйте через {error.retry_after} секунд.")

If you need to store cooldowns between restarts - in this case, you will most likely have to create your own implementation. The simplest option is to store the current time as an integer and compare it with the current time on the next execution

Answer 2

use python-crontab to implement time actions.
and to see if the command is repeated / not used - connect the .json file / database.
