    _inherit = 'stock.quant'
    inventory_value_charge = fields.Float('Total Value',store=True,compute='update_stock_value')

    @api.one
    @api.depends('qty')
    def update_stock_value(self):
        stock_price_obj = self.env['stock.price.partition'].search([('id', '!=', False)])
        val_obj = stock_price_obj.search([('reception.pack_operation_product_ids.pack_lot_ids.lot_id.id', '=', self.lot_id.id)])
        if val_obj!= False:
            val_obj.calccule_price()
        else:
            self.inventory_value_charge=self.inventory_value
        #stock_price_obj = self.env['stock.price.partition'].search([('reception.pack_operation_product_ids.pack_lot_ids.lot_id.id', '=', self.lot_id.id)])
