Description

Covers items 1 and 2 of #2624.

Rich messages were sent with rich_message.to_json() only. A media object built from an InputFile is serialized as an attach://<name> reference, but the file itself was never sent, so uploads in InputRichBlockAnimation, InputRichBlockAudio, InputRichBlockPhoto, InputRichBlockVideo, InputRichBlockVoiceNote, InputRichBlockDocument and InputRichMessageMedia could not work.

• InputRichMessage.convert_input_rich_message() returns the JSON and the files of every InputMedia in the message, collected with each media's own convert_input_media() (so thumbnails and video covers are included). It looks through media and blocks, including blocks nested in list items, collages, slideshows, details and quotations.
• send_rich_message, send_rich_message_draft and edit_message_text send those files, in both apihelper.py and asyncio_helper.py. They already used POST. A rich message without uploads has no files, so the request is the same as before.

edit_ephemeral_message_text also takes a rich_message; I left it as it is because #2624 doesn't list it, but it could use the same helper.

Describe your tests

New tests/test_rich_message_uploads.py, which replaces _make_request / _process_request and checks what would be sent:

• a rich message whose list item contains a photo block, plus an InputRichMessageMedia video, sends both files, under the names that the attach:// references in the JSON use, for each of the three methods (sync and async);
• a rich message without uploads gives no files.

The tests fail without the change and pass with it. pytest tests --ignore=tests/test_telebot.py: 290 passed, 2 skipped. This PR is independent of #2639 (checklists and replace_sticker_in_set, item 3 of #2624).

Checklist:

• I added/edited example on new feature/change (if exists)
• My changes won't break backward compatibility
• I made changes both for sync and async

What changed in this PR

This PR fixes rich-message media uploads for items 1 and 2 of #2624 by sending file attachments alongside the serialized message through the existing upload handling.

Changes:

• Collects media files from rich-message media entries and nested blocks using existing media converters.
• Forwards attachments in synchronous and asynchronous send, draft, and text-edit methods.
• Adds regression tests for nested uploads, attachment-name matching, and messages without uploads.

File	Description
tests/​test_rich_message_uploads.py	Tests attachment forwarding for sync and async methods.
telebot/​types.py	Adds recursive rich-message attachment collection.
telebot/​asyncio_helper.py	Passes collected files to asynchronous requests.
telebot/​apihelper.py	Passes collected files to synchronous requests.

            elif isinstance(value, (InputRichBlock, InputRichBlockListItem, InputRichMessageMedia)):
                for item in vars(value).values():
                    collect(item)

IMHO it's functional but highly inaccurate approach. For now it's better then nothing, but I prefer to have more convenient way, when code operate more precisely...

Thank you.
