i have pos_order_total field in contact tree view , and it's calculates perfecly if store=False , but if store=True it doesnt calculates if i make another pos order for client. how can i make this work with store=True. 
Maybe i need to add some depends fields. i tryed

from odoo import api, fields, models


class ResPartner(models.Model):
    _inherit = 'res.partner'
    
    order_id = fields.One2many('pos.order', 'amount_total')
    pos_order_total = fields.Monetary(
        string='POS Order Total',
        compute='_compute_pos_order_total',
        store=True)

    @api.depends('order_id')
    def _compute_pos_order_total(self):
        Order = self.env['pos.order']
        for partner in self:
            total = 0.0
            domain = [('partner_id', '=', partner.id)]
            for o in Order.search(domain):
                total += o.amount_total
            partner.pos_order_total = total

When you keep store=True, your compute function will be only called when the depends field value is changed.

In your above code, if store=True

_compute_pos_order_total will only be called if order_id field is changed in partner.

Hope this helps.

Thank You
