Adding a margen field to sale order lines in sale orders

E.M.

I want to add a computed field "markup" to sale order lines in sale orders (quotes/sales orders).

I have created the model:

class SaleOrderLine(models.Model):
    _inherit = "sale.order.line"

    markup = fields.Float(compute='_compute_markup', digits=dp.get_precision('.2f%'), store=True)

    def _compute_markup(self, order_id, product_id, product_uom_id):
        frm_cur = self.env.user.company_id.currency_id
        to_cur = order_id.pricelist_id.currency_id
        purchase_price = product_id.standard_price
        if product_uom_id != product_id.uom_id:
            purchase_price = product_id.uom_id._compute_price(purchase_price, product_uom_id)
        ctx = self.env.context.copy()
        ctx['date'] = order_id.date_order
        price = frm_cur.with_context(ctx).compute(purchase_price, to_cur, round=False)
        return price

        price = frm_cur.with_context(ctx).compute(purchase_price, to_cur, round=False)
        return price

And a new view which inherits sale.view_order_form:

<?xml version="1.0"?>
<odoo>
    <record id="view_order_form_margin" model="ir.ui.view">
        <field name="name">sale.order.form.margin</field>
        <field name="model">sale.order</field>
        <field name="inherit_id" ref="sale.view_order_form"/>
        <field name="arch" type="xml">
            <xpath expr='//field[@name="order_line"]/form/group/group/field[@name="price_unit"]' position="before">
                <field name="markup"/>
            </xpath>
        </field>
    </record>
</odoo>

But the field is not shown (the view appears when you check views that inherit current view). I have reloaded everything, restarted the server and cleared the browser cache.

Any tip on why the field is not being shown is welcomed. Maybe the Xpath expression? Thanks.

Hi EM,

Just make a slight change in the given Xpath like this, make it tree instead of form

<xpath expr="//field[@name='order_line']/tree//field[@name='price_unit']" position="before">
          <field name="mark_up"/>
</xpath>

Hope this can help you,

Thanks
