CalDAV

If you are using the baikal calendar server (https://github.com/fruux/Baikal/releases) you could specify “?export” in you caldav calendar url to get the stuff exported as ICS which will work with the MagicMirror calendar module.

Hi,
I am using Baikal on my Synology and want to create an ics file of the data.
Can you explain the ?export principle

Thanx!

Beh

@poekel You just add ?export to your calendar URL like this (example for baikal):

https://dav.example.org/dav.php/calendars/[username]/[calendarname]?export

Note, that [calendarname] is the internal name of your calendar in baikal. You can look it up in the baikal admin interface.

In addition: You can use digest authentication instead of basic auth for the calendar module, if you set the sendImmediately option to false.

Hi,
I have tried this -> https://dav.example.org/dav.php/calendars/[username]/[calendarname]?export already and it ask for a login and password.
When i try this on my mac i get this:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 296 bytes) in /volume1/web/baikal/vendor/sabre/vobject/lib/Parser/MimeDir.php on line 633

Its the calendar op my wife and she holds a lot of entries (4000)in the calendar and I think that is the problem (memory exhausted) . I does not work…

Any ideas welcome

Hey @poekel,

You can limit the export with some options. Since baikal uses sabre/dav you can use the options provided on the sabre/dav website here.

Maybe it is helpful for you, if you limit the export with the start and/or end options. You have to use unix timestamps for this. Converters can be found easily via a google search.

Here’s an example:

http://dav.example.org/calendars/user1/mycalendar?export&start=1391707119&end=1391707215

Maybe you just want to use the start option with today’s value. This would suffice for now I think…

Hi,
Thanx for all the help. It looks like a short workshop Baikal :)
I dont know if i am on the right track. I want to automate it. That is that items in the calendar show up on the mirror.
Is’nt there a simple way ? ( Export to some ics file ?)

Thanx!
Poekel

Beh

@poekel I don’t know, if I understand this right. But the ?export option already triggers a download for an .ics file (with all calendar events). I’m using this on my mirror with baikal and it works fine…

poekel

Hi,
The command works fine and i converted the time/datestamps. I think there is something wrong with the stamps, because
i get a file of 146 bytes whatever i do…
I have to play with it. :)
How do you keep the calendar up-to-date on the mirror ?
( my wife holds the calendars for all the family members so …)

poekel

Hi,
How do you append the username and password ?
I think it works but it gives me a Authorization failed.

poekel

Beh,
I think i have got the right syntax to retrieve the ics files from baikal.
Can you explain how you did it on the mirror?

poekel

@beh

I have read your workaround…
I am using Baikal on my synology.
i do NOT have this > https://dav.example.org/dav.php/calendars/[username]/Events?export folder

http://192.168.1.xx/baikal/html/dav.php/calendars/xxxx/calendar-name?export&startdate=1488672000 (=example)

How do i get the record from Baikal in 1 file given a certain start-end date in a file from the command line.
If that works i can change the url in the MM2 config.js file and point to that created file
Please help …

Beh

Hey @poekel
you have to use the keyword start instead of startdate.
It’s described in the sabre/dav documentation here: http://sabre.io/dav/ics-export-plugin/

So your request should look like this:
http://192.168.1.xx/baikal/html/dav.php/calendars/xxxx/calendar-name?export&start=1488672000

You can use this URL in your MM2 config file. It returns a valid .ics file. I’m using this on my mirror too.

And please note, that your calendar-name must be the internal name in Baikal (you can look this name up in the admin settings when you edit a calendar)

poekel

@Beh

Thanx for the link!.
It works, it creates a file with nothing more than this:
BEGIN:VCALENDAR
VERSION:2.0
CALSCALE:GREGORIAN
PRODID:-//SabreDAV//SabreDAV 3.1.3//EN
X-WR-CALNAME:XXXXXXXXXXXX
X-APPLE-CALENDAR-COLOR:#FF2968
END:VCALENDAR

164 bytes

How do you handle the username and password that goes with the calendar in baikal?
Does the link in the config.js not ask for a username and password for the baikal calendar ?

Beh

@poekel

I will try a request with a start parameter when I’m home and test if it works with my Baikal server.

For user credentials:

Just add user and pass to your calendar config like this:

config: {
    calendars: [
        {
		url: 'http://192.168.1.xx/baikal/html/dav.php/calendars/xxxx/calendar-name?export&start=1488672000',
		symbol: 'calendar',
		user: 'USERNAME',
		pass: 'PASSWORD'
        },
    ],
}

Additionally, Baikal uses Digest authentication. To use this, you have to change the sendImmediately option in the calendarfetcher.js to false. (As I already described above)

The option is located here. The file is located in MagicMirror/modules/default/calendar/calendarfetcher.js

In a future version of MM2, there will be an option for this directly in the config file so you don’t have to change this in calendarfetcher.js. I already submitted a pull request for that.

Beh

Hey, @poekel

after some trying on my Baikal server, I found out, that just the use of the start parameter alone is not working indeed.

However, I was able to get a request, if you add the componentType option to the request URL. You have to filter the type to VEVENT. But thats no problem, because the documentation says, that this is the only working type for export anyway.

So I got valid answers with the following URL scheme (including recognized timestamp):

https://dav.example.com/dav.php/calendars/USERNAME/calendarname?export&start=1490745600&componentType=VEVENT

Hi gentlemen,

I’m sorry to reopen this old topic.
What you are succeeded to do here it’s exactly what I search to do but it doesn’t work on my MagicMirror.

I have a Syno with Baikal (http://ipaddress/baikal/admin)
I have a user (homemagic) with his calendar (default)
My calendarfetcher.js is up-to-date (v2.2.0)

URL I use for :
http://ipaddress/baikal/cal.php/calendars/homemagic/default?export&start= 1514761200&componentType=VEVENT

Work on my android mobile with Caldav Sync Free Beta (PlayStore)
Work on ThunderBird
Doesn’t work on my MagicMirror :'(
My web browser (IE) return an error when I try to export

Someone could help me please :)

Beh

@OsCourt I think you need to use dav.php instead of cal.php on newer baikal versions. Also you need to use digest authentication with the calendar module of the mirror. It’s described in the readme of the module.

OsCourt

Thanks @Beh.

I don’t have dav.php file in my baikal folder on my Syno :/
I had already read the readme and I have the digest authentication in the mirror:

config: {
                                calendars: [
                                        {
                                                symbol: "calendar-check-o ",
                                                url: 'http://ipaddress/baikal/cal.php/calendars/homemagic/default?export&start=1514761200&componentType=VEVENT',
                                                auth: {
                                                       user: "homemagic",
                                                       password: "pass",
                                                       method: "digest"
                                                      }
                                        },
                                ]
                        }

Hi @poekel,

How have you installed baikal on your Syno ?
