Hi Gets,

Here, I need to show the count of Assets which is the same sparepartslinitem added.

Please help to get count of Many2one field in "set_countofasset"

using v12 community.

from odoo import models, fields, api


class Asset(models.Model):
    _name = 'asset'

    name = fields.Char(string="Code", required=True)
    assetname = fields.Char(string='Asset Name')
    sparepartslines = fields.One2many('spareparts_lineitem', 'asset', string='Spareparts')
    qtyinasset = fields.Float(String="Qty in Asset", compute='set_qtyinasset', readonly=True)
    # qtyinsystem = fields.Float(String="Qty in System", compute='set_qtyinsystem', readonly=True)

    @api.depends('sparepartslines.quantity')
    def set_qtyinasset(self):
        for rec in self:
            total = 0.0
            for line in self.sparepartslines:
                total += line.quantity
            rec.update({'qtyinasset': total})

class Spareparts(models.Model):
    _name = 'spareparts'

    name = fields.Char(string="Item number", required=True)
    description = fields.Char(string='Description')


class Spareparts_lineitem(models.Model):
    _name = 'spareparts_lineitem'

    name = fields.Many2one('spareparts', string="Item number", required=True)
    description = fields.Char(string='Description', related='name.description', store=True, readonly=True)
    quantity = fields.Float(string='Quantity', required=True)
    quantityinstore= fields.Float(string='Qty in Store')
    asset = fields.Many2one('asset', string="Asset")
    countofasset = fields.Float(string='Qty in Store', compute='set_countofasset', readonly=True)
