Members cannot delete their own files

[nxmndr]

Bug Report

Current Behavior
Admins can delete their files and other member's, but members cannot delete their own. A file deleted by an admin also remains in the media manager view until the page is reloaded.

Steps to Reproduce

1. Go to /admin#/extension/fof-upload as an admin and give the Member role permissions to Upload, View and Delete files.
2. Go to /u/<me>/uploads as a Member.
3. A delete button has appeared near each file. Clicking on said button results in 403 error.

Expected Behavior
Having the Delete permission as a member should allow to delete one's own files.

They should also disappear from the view without requiring page reload.

Possible solution(s)
I believe there should be additional View and Delete permissions for other users files.

Hi @nxmndr thanks for the bug report! Are you able to reproduce the permission issue when only fof/upload is enabled (besides the Flarum 1st party extensions)?

Regarding the page reload being required; in this sense it's not really a bug, but a feature which would have to be implemented. A web socket connection would be required for this to work, which could optionally be supported (for example with blomstra/realtime). Currently, this isn't a very high priority, but PRs are always welcome!

[nxmndr]

I can reproduce it indeed =)

I re-enabled it too.

A websocket ? I don't mean the user seing changes made by admin instantly, I mean the admin not seing the result of the deletion they made themselves as in click => nothing happens on the screen. I'm still new to Flarum but I think calling GET /api/fof/uploads once POST /api/fof/upload/delete is done would be enough (might even include it in the POST result).

(edited for clarity)
