nextcloud | User rights. Download but don't read. How to implement?

Question

System administration

Conditions.
Cloud NextCloud on UbuntuServer 20.04.
There are two users in the cloud: " Teacher " and " Student ".
Two folders with subfolders: " Assignments " and " Completed work ". In subfolders: " Groups " and below " Items ".

Task.
The teacher has the right to " Read/Write " in all folders. The student has the " Read " permission in the " Assignments " and " Write " permissions in the " Completed work " folders
The student should not see the files uploaded by other students under the same account, but should be able to upload their own (the number of users is such that it is simply impossible to give everyone an account). You can partially solve it with the " DropFiles " function by creating a link with the "Download only" right , but there will be about two hundred subfolders, respectively, the same number of links.

Answer 1

The software is not well suited to your task, consider implementing something more relevant.

. What to do)) ?? You can load everything in one folder, and explain to students how they should name their assignments FACULTY_GROUP_FULL NAME. Then you will sort or write a script.

Answer 3

It seems like regular NextCloud functionality:

True anonymously without any authentication. Until the page is updated, he sees which files he uploaded, updated - disappeared.
