Callback issue (how to properly use them about notion-py

[gubikmic]

I'm using the above snippet along with monitor=True, start_monitoring=True for NotionClient (like mentioned here #139 by @ekopach) and it reports cards that didn't change.

Changing only Card 3:

The record's title is now: Card 3F
Here's what was changed:
[('change', ['properties', 'title', 0, 0], ('Card 3', 'Card 3F'))]
The record's title is now: Card 1
Here's what was changed:
[('add', '', [('shard_id', 439132)]), ('add', '', [('space_id', '027dab3e-b3fa-43b9-b75a-90e21b39951d')])]
The record's title is now: Card 2
Here's what was changed:
[('add', '', [('shard_id', 439132)]), ('add', '', [('space_id', '027dab3e-b3fa-43b9-b75a-90e21b39951d')])]
The record's title is now: Card 3F
Here's what was changed:
[('add', '', [('shard_id', 439132)]), ('add', '', [('space_id', '027dab3e-b3fa-43b9-b75a-90e21b39951d')])]
The record's title is now: Card 1
Here's what was changed:
[('remove', '', [('shard_id', 439132)]), ('remove', '', [('space_id', '027dab3e-b3fa-43b9-b75a-90e21b39951d')])]
The record's title is now: Card 2
Here's what was changed:
[('remove', '', [('shard_id', 439132)]), ('remove', '', [('space_id', '027dab3e-b3fa-43b9-b75a-90e21b39951d')])]
The record's title is now: Card 3F
Here's what was changed:
[('remove', '', [('shard_id', 439132)]), ('remove', '', [('space_id', '027dab3e-b3fa-43b9-b75a-90e21b39951d')])]

Am I using notion-py incorrectly or is this a current issue?
I saw in the readme that it says

(Note: Notion->Python automatic updating is currently broken and hence disabled by default; call my_block.refresh() to update, in the meantime, while monitoring is being fixed)

I'd appreciate more info on this. Thanks a lot!

Note: I also tried just calling add_callback(my_callback) instead of calling the my_callback function but then it simply doesn't return anything and ends.

That would be the correct usage. The way it's coded in the sample is immediately executing your callbacks in the loop (which is why you see all of them printed).

In terms of it exiting at the end, you need to do something to keep the process alive (because otherwise the watcher thread dies with your main Python thread). This could either be a loop with time.sleep(<n>), or simply an input() at the end of the file, so that it will keep the process going until you hit enter or CTRL-C.

This works for me:

from notion.client import *

token_v2 = "<token>"

client = NotionClient(token_v2=token_v2)

def watch_completed_milestones():

	cv = client.get_collection_view(
		"https://www.notion.so/learningequality/e91d78e05fcc445a99ebbabe5c54428a?v=aafe1755187343d2a2b5b03d36f2a6c4"
	)

	def my_callback(record):
		print("The record's title is now:", record.title)

	for block_row in cv.collection.get_rows():
		print("Adding callback for:", block_row.title)
		block_row.add_callback(my_callback)

watch_completed_milestones()

print("Ready and watching!")

input()

Let me know how it goes!

Thanks, ill try it out. You might be interested to know that there’s a few of us developer focused notion users here on slack. https://www.notion.so/notionhacks/Notion-Hacks-27b92f71afcd4ae2ac9a4d14fef0ce47
