How to add an image from a link to a container

[dawn wave]

you use the https://docs.pycord.dev/en/master/api/ui_kit.html#discord.ui.Container.add_file

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/kotiklinok/PythonProjects/MaidTouchiBot-pycord/.venv_vps/lib/python3.11/site-packages/discord/bot.py", line 1154, in invoke_application_command

In components.0.components.2.file.url: This UnfurledMediaItem does not support arbitrary external urls. You must use the `attachment://` reference system.

I tried this before asking, but decided to repeat it to send the error.

[dawn wave]

do you understand what the error means?

[golden quail]

relatively

I'm not sure where I could put the image URL so that I could use attachment://.

[paper kelp]

.tag file

[rotund egret]

Tag not found.

[paper kelp]

.tag attachment

[rotund egret]

Tag not found.

[golden quail]

[paper kelp]

.tag local-file

[rotund egret]

f = discord.File("some_file_path", filename="image.png")
e = discord.Embed()
e.set_image(url="attachment://image.png")
await messagable.send(file=f, embed=e)```

[paper kelp]

This one

Just the first part

Ignore the embed part

[golden quail]

But this is not a file

its link

It turns out I need something to work with non-local.

[paper kelp]

you can use the IO lib

[paper kelp]

import io
import aiohttp
import discord

def whatever() -> None:
    url = "https://example.com/some-image.png"

    async with aiohttp.ClientSession() as session:
        async with session.get(url) as resp:
            await resp.raise_for_status()
            data = await resp.read()

    file_bytes = io.BytesIO(data)
    file_bytes.seek(0)

    fle = discord.File(file_bytes, filename="filename.png")

[vagrant light]

you should be using MediaGallery for this, not File

[golden quail]

I'm having trouble understanding how to use it.

[vagrant light]

you create a MediaGallery, then you can use gallery.add_item(image_url)

a gallery can have up to 10 items

[golden quail]

gallery = discord.ui.MediaGallery()
gallery.add_item(image_url)

[vagrant light]

typo but yeah

[golden quail]

I'm a little confused about how this should be added to the container. I've tried all the options with simple addition.

[vagrant light]

you add the gallery to the container

if you're still having trouble, could you show your code?

[vagrant light]

if you've already constructed MediaGallery, Container.add_item is correct

[golden quail]

I'll run it with item now and send the error.

08-12 02:56:00 - bot.commands.get_pictures - ERROR - func create_containers_with_pictures: 'file_url'

[vagrant light]

that's something you've done wrong

do you not have a full traceback

i can only guess that's a keyerror on post

(tip: your try-except is way too loose)

[golden quail]

I added another try-except and everything worked

I'm trying to change the view via buttons. I am removing all items and adding a pre-saved container.

What am I doing wrong? There is no error

[vagrant light]

1. you should use interaction.edit
2. you added the buttons to the container, so running clear_items and adding the container back... results in no change

Container has a remove_item function - this can take either the Item itself, or its id or custom_id. If you store data about the buttons, removing them should be trivial.

or you should only modify a copy of the container rather than the original passed in

[golden quail]

It's not. There are two different containers. self.container is a container without buttons, and the container in __init__ has buttons. There in __init__ they add buttons to it

[vagrant light]

They are the same, your function modifies the original container the entire time

That's just how referencing works in Python

[golden quail]

I'm not sure that's true. I'm gonna have to look at

[vagrant light]

I reran your same code but added remove_item calls in the interaction callback, and it worked as expected; you're not seeing any edits because discord thinks there's nothing to edit

[golden quail]

I was able to write this. Thanks for your help.

[golden quail]

I want to use message_command on servers where there is no bot. Is this possible, or am I misunderstanding something?
