Here's what everything looks like

From the design side:

"Select a user" and "Search for a user…" are redundant, it's fine to just have the second if it's baked into the component anyway, so without the title. The input field should also be full-width, and Add should be a primary button.

I wonder why delegation should be its own item in the sidebar instead of just a section in Settings? I'd rather have it just there. And at that point, have + Add delegate be full-width as well.

hamza221 · 2026-05-05T09:39:25Z

The pre-existing sharing logic doesn't work for delegation

A clear indication of Calendar "owner" should be visible

Thanks for the review! How does this look?

(I know that having delegates under delegation looks a little weird as title organization but that's the setting section with the form group component, and u can't not have titles for both)

GVodyanov · 2026-05-06T14:56:08Z

It took me a while to figure out but here is everything working

GVodyanov · 2026-05-06T14:58:59Z

You get the icon here to show its delegated

Looks good from the design side :)

GVodyanov

Thanks a lot for fixing the broken stuff @hamza221! Please don't merge this for now though because you accidentally removed the information on whether people are read/write delegates in settings, I'll re-introduce that.

EDIT: NOT TRUE

GVodyanov · 2026-05-24T21:13:14Z

Revoking access also stopped working

EDIT: NOT TRUE

GVodyanov · 2026-05-24T21:14:34Z

Share with delegator -> delegator delegates -> delegatee doesn't see avatar of sharer

EDIT: NOT TRUE

hamza221 · 2026-05-24T21:50:39Z

doesn't look like you're on latest, please pull and build again

I can't reproduce, but please fix if you can

The CDav library should be responsible for creating the specific urls the Calendar app should not need to know how to format a dav url

This will need to wait until the cdav pr is merged, then the library version will need to be bumped in this pr

One last comment, this feature needs a version gate for 34 unless we are back porting all the server changes

Feature gate added

No new features were adeed to server, all fixes, all to be backported to 32, no gating actually needed.
ps: just clarifying, I'm okay with the gating if that's the decision, but the feature can work for all Nextcloud versions with the frontend and cdav changes included >=32

Update: should be gated to >=34

Pull request overview

Adds front-end support for calendar delegation (proxy access) so delegated calendars can be discovered, displayed, and managed in the Calendar UI, gated by Nextcloud version support.

Changes:

Introduces a new Pinia delegation store to fetch delegators/delegates and load delegated calendars into the calendars store.
Updates Calendar list/pickers/headers to visually distinguish delegated calendars and group them by delegator.
Adds a Delegation section to Calendar settings for managing delegates.
