This is somewhat the project.task hierachy:
"TASK 1" -child_ids----parent_ids-"TASK 2"-child_ids----parent_ids-"TASK 3"-message_follower_ids
The filter domain should allow follower of TASK 3 to read TASK 2 and TASK 1:
(1) - followers can read following tasks (2) - followers can read parents/grand parents of followed tasks
This filter allows (1):
[('message_follower_ids','in',[user.partner_id.id])]
How can I allow (2)?
Thanks!
