    for ordr_ln in self.order_line:
        if ordr_ln['qty_available'] < 0:
                warning_mess = {'title': 'Opps! No hay stock',
                                'message': 'No hay suficiente Stock '}  


@api.multi
def action_delete(self):
    for order in self:
        order.order_line.filtered(lambda l: not l.product_uom_qty).unlink()

The view in XML

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <record model="ir.ui.view" id="view_order_form">
        <field name="name">sale.order.form</field>
        <field name="model">sale.order</field>
        <field name="inherit_id" ref="sale.view_order_form"/>
        <field name="arch" type="xml">
            <xpath expr="/form/sheet/notebook/page/field[@name='order_line']" position="before">
                <button name="action_delete" type="object" string="Clean" groups="sales_team.group_sale_manager"/>
            </xpath>
        </field>
    </record>
</odoo>

And the error is AttributeError: type object 'sale.order' has no attribute 'action_delete'.

These code must be to Odoo 12

Thanks you.

Answer 1

You got the NameError: name 'models' is not defined because you did not import models.

You can use filtered to get lines with quantity equal to 0 and then call unlink method on the result (record set).

from odoo import models, api


class SaleOrder(models.Model):
    _inherit = 'sale.order'

    @api.multi
    def action_delete(self):
        for order in self:
            order.order_line.filtered(lambda l: not l.product_uom_qty).unlink()

In this case the button type should be object and its name should be the method name.

<button name="action_delete" type="object" string="Clean"  groups="sales_team.group_sale_manager"/>
