Calendar not updating

[matt216]

@sdetweil I think you are potentially right. For baikal I have followed such advice as here: https://forum.magicmirror.builders/topic/434/caldav/4?_=1704811423495 where it was advised just adding ?export to the end of the cal URL to generate the ics file, but it is not an actual ics link.
I shall work along those lines…

[sdetweil]

@matt216 i test others problems by building an ics FILE and using the url

http://localhost:mirror_port/modules/default/calendar/????.ics

so it doesn’t have to be ON a ‘server’… just has to be an ICS format file.
linking to google, the url returns that data when the calendar does a get request
same as for the local file. BUT we depend on the data changing…
the cal module does not know that ‘this’ fetch was or was not different than the last fetch.
we don’t keep a diff… we just get the current data and present it.

if it didn’t change then nothing changes

[matt216]

@sdetweil Trying this.
Steps:

1. add new test event scheduled tomorrow
2. verify event on another device, proving calendar server sync
3. curl .ics file from server, find test event
4. set calendar module as described in your post above

Result:
calendar loads successfully, but still does not show new event.

Event as shown in ics file:

I think MagicMirror does not like the baikal server - no events created since I migrated from iCloud to self-hosted baikal are showing. Can you see anything unusual in the ics event above @sdetweil ?

[matt216]

@sdetweil so I’ve just spun up a radicale calendar server and added a few test events, then some more - works perfectly!

Looks like a problem with baikal integration

[sdetweil]

@matt216 no. i created an ics and ran mm against it

[sdetweil]

@matt216 can u send me the curl ics from the baikal server where the events don’t show??
(if you are willing)
rename to .txt

[matt216]

@sdetweil this is from the curl’d ics file, showing one of the events that will not display on the mirror display:

BEGIN:VEVENT
CREATED:20240109T161646Z
DTEND;TZID=Europe/London:20240110T170000

END:VEVENT

I’d be happy to send over the contents of the ics file before events start, if that would be helpful? Far too much personal family info to send the whole thing, Im afraid (again, no offence intended)!

[sdetweil]

@matt216 I used that event in an ICS and it displays just fine.

so I think this is not the events but some communications problem.

the fact that you have it working with another local hosting server tells me it’s something other than the data

[matt216]

Initial testing with the apache version of the baikal container looks promising (I’m currently having problems with the nginx version). Will continue testing along these lines…

[matt216]

OK interesting. I created a brand new calendar server. Empty. Added one event to it and configured the mirror calendar module to use this server. It shows the one single event ok. I added a second new event to the calendar and this also shows on the mirror. Seems to work as expected - new events are showing!

Then I import my whole famlly calendar and run the same test. I now have 5 family events showing on the calendar. But if I add a new event that should show within my 5 events, it does not show. :(

Debug logs >somefile.txt show the mirror is picking up the new event from the ics file, it’s just not showing on the display.

[matt216]

@sdetweil I wonder if I could run a nightly cron job to purge the calendar module or something similar…? Not sure how the calendar fetcher works.
It still feels like the calendar will load an ics link ok the first time, but is not displaying events created since that first load.
Nightly purge and re-connect would be acceptable, I think. Any advice there?

[sdetweil]

@matt216 there is no way to programmatically trigger a calendar refresh. you have to restart mm

but you could do this w pm2

pm2 restart MagicMirror

(or it’s number)

in the current state does the broadcasting message indicate a change in number of events?

[matt216]

@sdetweil yes, the broadcasting event number increases by 1 when I add my new event, but the event does not show on the display.

[sdetweil]

@matt216 can u show me the cal config again… as far as I can tell, the ONLY reason its not displayed is that the count (maximumEntries) clips off the total number of events

actually there are more conditions… in calendar.js
but they are all configurable

			for (const e in calendar) {
				const event = JSON.parse(JSON.stringify(calendar[e])); // clone object

				if (this.config.hidePrivate && event.class === "PRIVATE") {
					// do not add the current event, skip it
					continue;
				}
				if (limitNumberOfEntries) { (//called with true) 
					if (event.endDate < maxPastDaysCompare) {
						continue;
					}
					if (this.config.hideOngoing && event.startDate < now) {
						continue;
					}
					if (this.config.hideDuplicates && this.listContainsEvent(events, event)) {
						continue;
					}
					if (--remainingEntries < 0) {
						break;
					}
				}

and after filtering them out , apply the number of days limit and max entries limit

		// Limit the number of days displayed
		// If limitDays is set > 0, limit display to that number of days
		if (this.config.limitDays > 0) {
			let newEvents = [];
			let lastDate = today.clone().subtract(1, "days").format("YYYYMMDD");
			let days = 0;
			for (const ev of events) {
				let eventDate = moment(ev.startDate, "x").format("YYYYMMDD");
				// if date of event is later than lastdate
				// check if we already are showing max unique days
				if (eventDate > lastDate) {
					// if the only entry in the first day is a full day event that day is not counted as unique
					if (!this.config.limitDaysNeverSkip && newEvents.length === 1 && days === 1 && newEvents[0].fullDayEvent) {
						days--;
					}
					days++;
					if (days > this.config.limitDays) {
						continue;
					} else {
						lastDate = eventDate;
					}
				}
				newEvents.push(ev);
			}
			events = newEvents;
		}

		return events.slice(0, this.config.maximumEntries);

[matt216]

@sdetweil

{
			module: "calendar",
			header: "--- Calendar testing ---",
			position: "top_left",
			config: {
				fetchInterval: 120000,
				timeFormat: 'absolute',
				maximumEntries: 5,
				broadcastPastEvents: false,
				calendars: [
					{
						url: 'https://my.cal.url/dav.php/calendars/family/default?export',
						auth: 	{
							user: 'family',
							pass: 'pass',
							method: 'basic'
							}
					}
					]
				}
		},

With the maximumEntries I currently have events showing several days in the future. When I am adding events to test this, I add the event to start just a few hours in the future so that it should show within the 5 events.

[sdetweil]

@matt216 lets make that maximumEvents: 20

for this test

[matt216]

@sdetweil Updated to 20. This now shows calendar entries all the way to early May but the test event that starts at 20:00 this evening does not show. There are actually lots of events over the next few days that are not showing.

[sdetweil]

@matt216 ok, lets add some debugging , then we can see what is received in the UI module and what is processed for display (after filtering)

~/MagicMirror/modules/default/calendar/calendar.js

about line 219

		const events = this.createEventList(true);
		Log.log("events to process="+JSON.stringify(events))  // add this line 
		const wrapper = document.createElement("table");

and around line 582

		for (const calendarUrl in this.calendarData) {
			const calendar = this.calendarData[calendarUrl];
			Log.log("before filter events="+JSON.stringify(calendar))  // add this line
			let remainingEntries = this.maximumEntriesForUrl(calendarUrl);

then in the browser developers window (ctrl-shift-i to open) select the console tab,
add cal to the filter field

you will see these two blocks

before filter events=[{"title":"Henry swim at Y","startDate":"1705156800000","endDate":"1705159200000","fullDayEvent":false,"recurringEvent":true,"class":"","firstYear":2024,"location":false,"geo":false,"description":false},{"title":"Henry swim at Y","startDate":"1705761600000","endDate":"1705764000000","fullDayEvent":false,"recurringEvent":true,"class":"","firstYear":2024,"location":false,"geo":false,"description":false},{"title":"Henry swim at Y","startDate":"1706366400000","endDate":"1706368800000","fullDayEvent":false,"recurringEvent":true,"class":"","firstYear":2024,"location":false,"geo":false,"description":false},{"title":"Henry swim at Y","startDate":"1706971200000","endDate":"1706973600000","fullDayEvent":false,"recurringEvent":true,"class":"","firstYear":2024,"location":false,"geo":false,"description":false},{"title":"Henry swim at 

and then

events to process=[{"title":"Henry swim at Y","startDate":"1705156800000","endDate":"1705159200000","fullDayEvent":false,"recurringEvent":true,"class":"","firstYear":2024,"location":false,"geo":false,"description":false,"url":"http://localhost:8090/modules/default/calendar/JUSTONE.ICS","today":false,"dayBeforeYesterday":false,"yesterday":false,"tomorrow":true,"dayAfterTomorrow":false},{"title":"Henry swim at Y","startDate":"1705761600000","endDate":"1705764000000","fullDayEvent":false,"recurringEvent":true,"class":"","firstYear":2024,"location":false,"geo":false,"description":false,"url":"http://localhost:8090/modules/default/calendar/JUSTONE.IC

[sdetweil]

@matt216 the before filter is what was sent from the parser
the events to process is what will be shown, limited to maximumEntries in length

[matt216]

@sdetweil Thanks Sam. Will have a go and report back.
