Initial implementation of ical support (untested)

GenieTim commented 1 year ago

This is a PR that introduces (in theory) an export of each course into the iCalendar format.

For now, it is a draft PR, as it is untested. This, because I did not manage to get the dev environment working again due to various conflicts, e.g. in the migrations, and not knowing how the S3 test instance must be set up exactly. I spent a few hours making progress, fixing one issue after another, but all in all I have the suspicion that it is a waste of time.

Please take a look, if this is a feature you are interested in at all. If yes, I would be thankful for some hints on how to properly setup the dev environement. I had managed to set it up a few years back (#275), but did not manage anymore this year, unfortunately.

Here some preliminary implementation notes in case you want to test/merge it as is:

The link is only shown in the "subscription" page, not on the public page of a course,
however, the link itself is public, insofar as that no login is required. Motiviation for that is, that it – in theory – allows to just copy the link for a continuous import into e.g. Google Calendar, rather than downloading it once, and therewith get later changes exported as well. Depending on how often course date and times change, this might be the wrong decision.
For now, it's only an export per course. In principle, offering one calendar per student/teacher for continous integration of courses that are subscribed/taught after the first import, would be the next step, if this iCalendar feature here is accepted.

Hi Tim! Sorry, you never got a reply. Somehow my notifications for this mirror of the repository were disabled. The feature is interesting and the calendar per student/teacher would also be a great benefit.

Sorry for the delay, December was a bit hectic. I still did not manage to test things, but at least I should have adressed your points for now

Thanks! And sorry for letting you wait again 😅

I tested the PR and added some changes to make everything work.
