Question About Power Levels

To modify power levels in nio, we need to use room_put_state event_type = "m.room.power_levels".

AFAIK: Synapse requires sending the full power level dictionary to the server when making modifications. Otherwise, values that are not explicitly set might get overwritten (or deleted). Is that correct?

I can’t seem to find a straightforward way to access this information in the correct schema structure, other than by fetching room events and modifying the last power level event as a base. The clients (rooms) have a PowerLevels object, but it doesn’t seem to fully represent the server schema.

It would be helpful to have a function that returns the server schema from here, perhaps something like a to_dict or to_json function. (Easy to implement, happy to do it)

Additionally, it appears that power levels in the object aren’t synced correctly; they seem to get updated only partially (this might be a separate issue).

Am I on the wrong track here? I’d appreciate clarification before opening a ticket. ;)

I was trying to figure out that also on myself. I think the only way to really know is to look in the synapse codebase (as the documentation don't say much) about what happens with values missing on modification. Other bots seems to "overwrite" the whole allow,deny field, but I'm unsure that can scale to the sizes required for the amount of home-servers you can find on a room.

I was thinking on just sending the "changes" with this method, but I haven't properly test it. Nor that I have any custom homeserver to try. Now to be able to do that, your software need to keep the "true state" stored on its own, and probably query the "room state" to see what keys needs to get updated. So your code can send an event and sync the "room state" to the "true state" desired.

Another way is just to blindly craft the event from your "true state" without any regard of the "room state" trying to overwrite it completely. My only worry is that you could (eventually) get an event size too large if the list of homeservers grow beyond a threshold.

I certainly could, but that is an extra request, for data that already is or should be available - thus not straightforward. The web clients don't do it either. - This why I thought I'm maybe doing something wrong.

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.
