please help
I need when I click Enregistrer Button to create those fields in the tree view on the bottom

for this example, I have quantity equal 12 so I need 12 lines to be created on the tree view with the values on the wizard view

the wizard code :

class LinesWizard(models.Model):

    _name = 'bons.wizard'

    w_contrat_name = fields.Many2one('contrat.contrat', string='Contrat')

    w_contrat_line = fields.Many2one('contrat.lignes', string='Ligne contrat')

    w_product_name = fields.Many2one('product.product', string='Produit')

    w_po_number = fields.Char(string='Numero PO')

    w_qtt = fields.Float('quantite', related='w_contrat_line.quantity')

    w_prix = fields.Float(string='Prix unitaire', related='w_contrat_line.unit_price')



    @api.onchange('w_contrat_name')

    def on_change_contrat_name(self):

        if self.w_contrat_name:

            self.w_contrat_line = False

            return {'domain': {'w_contrat_line' : [('ligne_ids', '=', self.w_contrat_name.id)]}}

        else:

            return {'domain': {'w_contrat_line': }}
