i have modified res.users with field supervisor (many2one of res.users) using custom module.

now i want users of CRM Leads and Contacts to access as below:

1) user can view his or her record only

2) and a supervisor can see his record only and all of his suordinates records

how i can add a record rule for above mentioned

i tried something like below for both but not working... what i am doing wrong or missing something?

['|', '|',  ('user_id', '=', user.id),('user_id', '=', False), ('user_id.user_ids.supervisor', '=', user.id)]

AND - OR

how i can create same types record rules to restrict as above mentioned but instead of supervisor what if I want to use Manager which marked in Employee?

please help.

regards
