[SOLVED] How do you find the ID of a user who sends a slash command with code outside of that command?

How do you find the ID of a user who sends a slash command with code outside of that command?

I am looking to find the user ID of the user who uses a slash command with code that gets executed when clicking a button on said message. interaction.user.id gives me the id of the button clicker, rather than the original slash command user.

EDIT: Sure I could save the user IDs along with the message ID in a database, but I was hoping to find a better and faster way to go about it.

Solution

You can use interaction.message.interaction_metadata.user.id.

If this is an XY Problem, you should know you can also nest the button callback inside the function which handles the original command, for example:

async def cookie(interaction: discord.Interaction):
    async def give_cookie(button_interaction: discord.Interaction):
        if interaction.user != button_interaction.user:
            await button_interaction.response.send_message("No cookie for you >:(")
            return
        await button_interaction.response.send_message("Here is a cookie: :cookie:")

   view = discord.ui.View()
   button = discord.ui.Button(label="Get a cookie")
   button.callback = give_cookie
   view.add_item(button)

   await interaction.response.send_message(view=view)
