Domain_force expression with one2many

Hello, My goal is to restrict user to access only Partners, which belong to the same company branch as the user. User is linked to company branches through res_users.company_ids field, Partner is linked to company branch through res_partner.branch_id field. Partner has an additional branch_id field for linking to company branch: class ResPartner(orm.Model): _inherit = 'res.partner' _columns = { 'branch_id': fields.many2one('res.company', 'Branch'), } Access rule: Access data of partners, which belong to branches that user is assigned to[('branch_id', 'in', [company.id for company in user.company_ids])] This domain_forse expression does work well actually, but my concern is if it is right to do list comprehension, maybe there is another way to achieve this with expressions like 'child_of', etc. without list comprehension? I have trouble figuring this out, as res_users.company_ids is a one2many. Thank you in advance.
