Hi All,

I couldn't  get the backorder and moveline in stock.picking table

Below i mentioned my code.

If have done any mistake in code plz correct me.

class StockPicking(models.Model):
    _inherit = "stock.picking"

    alert_count = fields.Integer(compute='_compute_alert', string='Quality Alerts', default=0)
    alert_ids = fields.Many2many('quality.alert', compute='_compute_alert', string='Quality Alerts', copy=False)
   
    @api.model
    def create(self, vals):
        res = super(StockPicking, self).create(vals)
        res.generate_quality_alert()
        return res

    @api.multi
    def generate_quality_alert(self):
        quality_alert = self.env['quality.alert']
        quality_measure = self.env['quality.measure']
        stockpick=self.env['stock.picking']
        for pick in self:
            backorder = stockpick.search([('backorder_id', '=', pick.id)])
            print(backorder)
            if backorder is True:
                for line in backorder.move_lines:
                    print(line)
                    measures = quality_measure.search([('product_id', '=', line.product_id.id)])
                    if measures:
                        print(measures)
                        quality_alert.create({
                            'product_id': line.product_id.id,
                            'picking_id': backorder.id,
                            'origin': backorder.name,
                            'company_id': backorder.company_id.id,
                            'order_id': False,
                            'ordered_quantity':line.product_uom_qty,
                            'pending_quantity':line.product_uom_qty,
                        })
