Well it is solved, and works perfectly now, thanks ! A big thanks to @sylvainjule for his wonderful help and plugin. Using the latest version (1.0.2) of Bouncer, and the following files :
/site/blueprints/users/editor.yml
title: editor
permissions:
access:
panel: true
site: true
settings: false
users: false
# ...
user:
changeRole: false
delete: false
update: false # else a user will be able to edit the page they have access to on their profile
fields:
canaccess:
label: 'This user will only be able to access :'
type: pages
multiple: false
options: query
query: kirby.page('projets').children
and the config.php file :
// bouncer
'sylvainjule.bouncer.list' => [
'editor' => [
'fieldname' => 'canaccess'
]
],
Thank you very much !
