Add the mimetype to the preview arrays

@tobiasKaminsky I guess a capability is needed, or will you just check for existance of the field?

I guess a capability is needed, or will you just check for existance of the field?

I am not sure, ideally there would be a way so that client get informed, once every app version has this included, so that I can remove the legacy code.

Are capabilities the best way for this? They cannot be removed at all, or other apps might break?

@nickvergessen can you update this to latest master? This fails due to unsafe-eval.

[tobiasKaminsky]

Simple rebasing seems to be enough

@nickvergessen objects is not documented here: https://github.com/nextcloud/activity/blob/master/docs/endpoint-v2.md

Can you clarify this on the following sample activity?

We have objects{}, but also object_id, object_name which are the same like one (the last) of objects{}?

objects{} holds the current path of the file? So on a deleted file it should be a path to trashbin?

@nickvergessen is there a way to backport this also to older version, e.g. those for Nc12/13? It would be a little nightmare to support both ways of preview fetching…

[nickvergessen]

No, just don't provide previews for 12/13/14

As for the object_* & objects{} information. That is the path of the moment when the activity happens. I guess the object_name should not be part of the API since it can/will change at least for files. But well, can't change the API and it was there when I started at OC back then.
That is also the reason why it is not documented, so people don't use it.

I will rebase this and fix the unit tests tomorrow, so we can get this in for 15

[nickvergessen]

Rebased and fixed unit tests
quick review @MorrisJobke ?

[MorrisJobke]

Code change makes sense 👍
