are public calendars always read only?

[shrippen]

hi,

i have just installed Davis and tried to create a public calendar. My goal is a calendar that I can edit and share to others who can only access read-only.

But so far when I set the calendar to public I lose the ability to edit the calendar at all. Thunderbird automatically sets that calendar to read-only. Kontact removes it completely.

Am I doing something wrong? How do you work with a public calendar?

Hi @shrippen

A public calendar is .. well ... publicly readable by anyone, but only the owner (the creator) can write to it.

Maybe reading this comment here might bring some clarity: #105 (comment)

I myself don't use public calendars in my setup, and don't use either Thunderbird or Kontact. @1Luc1, as sponsor of this feature, might be able to help maybe?

Hey,

right now we don't use this feature within production, but I tested it quite well and my I can help you with it. We don't use it in production, since we are waiting for the share feature for public calendars: Davis Roadmap

So maybe check if this is also your case, why you can't edit public calendars anymore. If not, may I ask you to show us, how you setup the whole thing step by step.

So here is what i did.

1. In the admin dashboard I have created a new user.
2. Create a new calendar for that user.
3. Add that calendar to thunderbird and kontact, logged in as the newly created user.
4. add a new entry into that calendar.
5. Set the calendar to public in the admin dashboard.
6. Try to add another entry into the calendar. Brings an error message. 403.

I don't see how I can create a public calendar that is still modifyable by its owner.

Just tested it and I can confirm, that after setting the calendar to public, it is not possible to add another entry into the calendar as owner of the calendar. @tchapi my you have a look. I tested it with v5.1.3 (SabreDAV 4.7.0)

Hey,

I'm seeing a weird issue as well - as soon as I set a calendar to public, it "vanishes" from iCAL and is no longer shown. Is that related maybe?

Hey,

thanks @tchapi for this awesome project - it really filled a gap for us! I'm just commenting here to say that we would also love to see public calendars being shareable (Davis Roadmap)!

Keep up the great work!

Hi @waza-ari @TwlyY29 @shrippen

Thanks for your patience on this 🙏🏼

I've identified an issue where Davis' custom implementation of public calendars is "shunted" by sabre/dav and doesn't return the correct ACLs when retrieved by the owner.

I'm working on a fix — I will probably need to modify the underlying implementation on Davis's side for it to be more robust.

Will keep you posted!

👋🏼 People,

Would you mind testing the changes in #239 to see if it fixes your issues? I have changed the actual database model to better fit the use case, as it was hard circumventing sabre/dav code.

Note: if possible, I'd recommend to NOT test this on your production instance. It shouldn't break anything, but just in case ... (there is a migration in there, adding a column)
