Calendar not updating

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

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

@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.

sdetweil

@matt216 you can also use this web site

https://codebeautify.org/jsonvalidator?/jsonvalidate

to paste in the data (from [ to ]) and then push the format button (in pink) to make it more readable, ctrl-f will allow you to search for the entry you are looking for

matt216

@sdetweil good tip, thanks.

Little update - I put maximumEntries back to 5 and all my events showed up! But then I added another event, pm2 restart and they disappeared again :weary_face:

We’re getting closer! I think you’re on to something with the maximumEntries effect. And also handling between back and front end.

I’ll have a go with editing calendar.js this weekend and report back.

Thanks

matt216

@sdetweil Hi Sam.
The before filter section is not showing the events that are missing. So not sent from the parser…?
The events to process section reflects what is seen in the before filter section.

Over the weekend the calendar looked good, but come Monday morning lots of events are missing. The mirror is currently showing events 10 days in the future even though there are plenty of events before then.

I have had a play with module config maximumEntries and limitDays to see if anything improves, but with no luck.

Thanks again,
Matt

sdetweil

@matt216 ok, go back to the prior parser

cd ~/MagicMirror
npm install node-ical@0.16.1

restart MM

matt216

@sdetweil said in Calendar not updating:

node-ical@0.16.1

Done. Different events shown on the mirror - events over the next few days rather than 10 days away! - but still events not displaying.

Browser dev tools indicate they’re sitll not getting parsed.
Server pm2 logs do show the events are being picked up from the calendar server e.g.
