i have a list of students (users) and i want to make a new role ( teachers ) such that

a specific teacher would have the permissions to access , view , edit the information of a group of students ( not all of them, just a few students that i would specify) 

how can this be done ?

Hi! I'm quite new to drupal 8 and twig, but this is something I thought would be rader easy to do, but I still struggle with.

I have a node type curriculum with two entity reference fields called 'optional' and 'mandatory'. Each of these reference fields contains a list of nodes. In the template, '{{ content }}' displays the entities together and not separates like I want to display it. I thought I could just write {{ content.field_mandatory }} and {{ content.field_optional }} to display them separately, but this shows nothing.

What am I missing here?
