note to self, https://github.com/discord/discord-api-docs/pull/7368 would be appropriate here too (webhooks may make full use of the new V2 components and link buttons, but not the existing interactive components)

[Lulalaby]

yeah agreed. we should get that in as well. i originally included that in my discord-docs, but since it was kinda separate, i removed it again since advaith made a separate pr

[NeloBlivion]

todo: changelog, example pls test within whatever limits you can https://discord.com/channels/881207955029110855/881735314987708456/1344584270601261067 if you get any errors apart from maze then ping me there

Sometimes when parsing a received components the code crashes here saying no attribute custom_id: https://github.com/Pycord-Development/pycord/blob/8fdf18ec0b7d47d395194470b21621ebc6b6d971/discord/ui/view.py#L464

that's odd, is_dispatchable should mean it has a custom id

[Paillat-dev]

Yeah I thought the same

[NeloBlivion]

Experiment flag has been lifted; this PR can now be freely tested by any user. You may have to force canary API; this can be done by running the below line in your main bot file.

discord.Route.API_BASE_URL = "https://canary.discord.com/api/v10"

Additionally, examples in the example/ui directory should be something to consider.

This could be done in a separate PR to not delay this PR.

[NeloBlivion]

When using a decorator in a container, should the items appear above or below items set in __init__

[Icebluewolf]

Can row not be used? But I would say below when not specified.

[RealBongoChongo]

Is there a way to add your own ActionRow?

[Icebluewolf]

The button limit was not increased correctly, this could most likely be fixed by allowing manual ActionRow creation and not bother fixing the weights system as of now (as suggested by RealBongoChongo). The 26th button is what causes the error.

Code

```py v = discord.ui.View() for i in range(33): v.add_item(discord.ui.Button(label=str(i))) ```

Traceback

``` Traceback (most recent call last): File "site-packages\discord\commands\core.py", line 138, in wrapped ret = await coro(arg) ^^^^^^^^^^^^^^^ File "site-packages\discord\commands\core.py", line 1082, in _invoke await self.callback(ctx, **kwargs) File "PycordTesting\components_v2.py", line 24, in components_v2 v.add_item(discord.ui.Button(label=str(i))) File "site-packages\discord\ui\view.py", line 341, in add_item self.__weights.add_item(item) File "site-packages\discord\ui\view.py", line 145, in add_item index = self.find_open_space(item) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "site-packages\discord\ui\view.py", line 131, in find_open_space raise ValueError("could not find open space for item") ValueError: could not find open space for item ```

[NeloBlivion]

Implementing ui.ActionRow alongside weights is not ideal and not a goal for 2.7; this will be added in v3.

Not copilot being almost completely worthless on this mildly large PR

[DTheIcyDragon]

hi, I am just trying out this addition with the default bot example, and I am recieving a 404 error. Is this an known or unknown problem? -> moved to Pycord Discord

[Paillat-dev]

@DTheIcyDragon Heyy, would you mind asking in the discord server https://discord.gg/pycord as this issue is not related to this pull request specifically ?

[Icebluewolf]

Would it be possible to not include timeout handling in views without an interactive component. I dont think there is any reason to save the view in the cache when there are no interactive components. This would also save a lot of memory in active bots that send a lot of containers in place of embeds where the current behavior saves the view for 3 minutes.

[iqnite]

I've now started to implement this PR in the Beta version of my bot, and I have a question: Is it possible to add an item to a container via decorator? Or is self.container.add_item(callback) the only way?

[NeloBlivion]

Is it possible to add an item to a container via decorator?

@button and @select work when subclassing container, same usage as in views

[NeloBlivion]

Would it be possible to not include timeout handling in views without an interactive component

This has been added through the new View.is_dispatchable() function - non-dispatchable views will no longer automatically call store_view when being sent

[NeloBlivion]

Kinda hefty but since this is already a large pr on Views i added some other conveniences

• New command, view and modal attributes on Interaction
• New events on_view_error and on_modal_error

Will go through full review comments and suggestions this weekend.

~~View.disable_all_items() does not disable section accessories. Is this intentional?~~

EDIT: MB I was using an older version.

[crashi-c]

self.disable_all_item() returns error AttributeError: 'MediaGallery' object has no attribute 'disable_all_items'

It looks like there's a problem with editing messages.

This is not new. It also happens in the stable version. I've complained about it several times, but they haven't fixed it yet.

@iqnite Please create a new issue with the necessary information, we'll look into it.

https://github.com/discord/discord-api-spec/commit/2a2605c2df77df198aef8fc78e298a3652cbd746

we have attachment_id on the UnfurledMedia object now

[Lulalaby]

and the file display component has two more fields: size in bytes and name ref https://github.com/discord/discord-api-docs/pull/7609

@NeloBlivion I think something broke with your recent pushes:

if payload["content"] or payload["embeds"]

in ``discord/webhooks/_async.py`

Is causing:
