@mtrnord:midnightthoughts.spaceMTRNord (they/them)

Hi :) I am kinda new to python matrix nio and I am getting AttributeError: 'dict' object has no attribute 'type' for events returned using await client.room_get_state(room_id.room_id).

I am doing a for ... in loop over state.events where the dict in the error is the event out of the events list. On which I am trying to compare the type with a string.

13:11:12
@mtrnord:midnightthoughts.spaceMTRNord (they/them)Any ideas why that happens?13:11:18
@mtrnord:midnightthoughts.spaceMTRNord (they/them)printing the event shows the type being present13:11:26
@mtrnord:midnightthoughts.spaceMTRNord (they/them) * printing the event shows the type key being present 13:11:32
@mtrnord:midnightthoughts.spaceMTRNord (they/them) I am doing if event.type == "event type": 13:11:56
@mtrnord:midnightthoughts.spaceMTRNord (they/them)
state = await client.room_get_state(room_id.room_id)

for event in state.events:
    if event.type == "m.room.message":
        ....
13:12:37
@mtrnord:midnightthoughts.spaceMTRNord (they/them) *
state = await client.room_get_state(room_id.room_id)

for event in state.events:
    if event.type == "state_event_type_here":
        ....
13:12:59
@tulir:maunium.nettulirpython doesn't allow dict access with dots like javascript does13:13:40
@mtrnord:midnightthoughts.spaceMTRNord (they/them) Ah. So its event["type"]? 13:14:17
@tulir:maunium.nettuliryes, looks like nio doesn't parse the events into dataclasses or anything like that, so they're just raw dicts13:15:09
@mtrnord:midnightthoughts.spaceMTRNord (they/them)Ok even pycharm assumed dot notation here :D but maybe it is confusing it with some other type13:15:41
@mtrnord:midnightthoughts.spaceMTRNord (they/them)ah it seems like there is an Event class which exists and it might have thought this applies here13:16:08

In reply to@tulir:maunium.net
yes, looks like nio doesn't parse the events into dataclasses or anything like that, so they're just raw dicts
Events usually yes, but iirc state values don't have any dataclasses at all

Another thing for room messages which are redacted I am getting lots of:

Failed validating 'required' in schema['properties']['content']:
    {'type': 'object',
     'properties': {'msgtype': {'type': 'string'}},
     'required': ['msgtype']}

On instance['content']:
    {}
Error validating event: 'msgtype' is a required property

when going backwards using await client.room_messages.

I dont care about the content but I do care about the message existing in the resulting list of events. Will they still exist or does this error cause them to disappear? 🤔

I'm familiar with the error message, and I was tracking it to: https://matrix-nio.readthedocs.io/en/latest/_modules/nio/events/misc.html

def validate_or_badevent(
    parsed_dict: Dict[Any, Any],
    schema: Dict[Any, Any],
) -> Optional[Union[BadEvent, UnknownBadEvent]]:
    try:
        validate_json(parsed_dict, schema)
    except (ValidationError, SchemaError) as e:
        logger.warning(f"Error validating event: {str(e)}")
        try:
            return BadEvent.from_dict(parsed_dict)
        except KeyError:
            return UnknownBadEvent(parsed_dict)

    return None

@nex:nexy7574.co.uknex (she/it)Is there an easy way to get each state update from each SyncResponse?23:40:01
26 Oct 2024
@ifiguero:matrix.orgifiguerothere is several custom events, and malformed ones, as not all clients behave properly. 01:58:51
24 Oct 2024
@nex:nexy7574.co.uknex (she/it)I don't want the events in this case, just state changes23:40:12

@ifiguero:matrix.orgifiguero IIRC there is m.room.member for changes in the user and ['m.room'. ('name' | 'topic' | 'avatar' | 'aliases' | 'canonical_alias' | 'encryption' | 'create' | 'join_rules' | 'history_visibility' | 'guest_access' | 'power_levels' | 'server_acl' | 'tombstone' | 'pinned_events')] seem to be room state changes. 02:30:11
@ifiguero:matrix.orgifiguero

they are all events. You get a copy of the current value if you query:

res = await client.room_get_state(room_id)

@ifiguero:matrix.orgifiguero *

they are all events. You get a copy of the current value if you query:

res = await client.room_get_state(room_id)

but also they get relayed by normal sync as they come by.

@fabian:alertrix.netFabian Hi, during my development of a django based application service I implemented a custom store class, which requires a synchronous context, which is not the case when using the AsyncClient, so i used asgirefs asgiref.sync.sync_to_async to mitigate django.core.exceptions.SynchronousOnlyOperation exceptions.
I would like to make these changes available to everyone in matrix-nio, i do not have any experience in working on other peoples projects yet, tho. Do i just push my branch ("synchronous-only-database") to github and create a pull request?
I have only tested it with the tests of my project so far. How do i run matrix-nio`s tests?
12:36:54
@ifiguero:matrix.orgifiguero I don't understand why you can't just call the sync method from your async function. I mean is non-ideal as you have some I/O delay but its not that you can't do it. 22:17:42
