i want to restrict user to projects on basis of user'employee_id's presence in project's field named :"employee_id" (many2many)

for example: if there is a project named "A" and in the employee_id field there is two employee named as : "1","2" who are linked to user : "1","2" resp.

now if user 1 tries to see project "A" , he will be able to do so.

but if user 3 tries to do to same he will not be able to see the project "A".
