I am trying to add a % field with the "sales margin" to each line in a sales order, so user can see sales margin for each item.
I already posted a similar question and I though I understood how to do it, but then I realized I didn't.
First thing I have to do is clearly to add a new field.
If I understood it right, it is needed to extend the class sales.order.line with the new field, and then define the extensions to the views.
Is 'sale_margin_percent.py' properly written? I would like to use if possible OdooV8 new API style, which is what I started to learn.
__init__.py
from . import sale_margin_percent
__openerp__.py
{
'name': 'Sales Margin Percent in Sales Orders',
'description': 'Provides sales margin percent information in Sales Orders, line by line',
'author': 'E.M.',
'depends': ['sale','sale_margin'],
'data': ['sale_margin_percent.xml'],
}
sale_margin_percent.py
# -*- coding: utf-8 -*-
from openerp import models, fields, api
class sale_order_line(models.Model):
_inherit = "sale.order.line"
_columns = {
'x_sale_margin_percent': fields.Float('Margen de Ventas', (4, 2)),
}
sale_margin_percent.xml
<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data>
<record model="ir.ui.view" id="sale_margin_percent_1">
<field name="name">sale.margin.percent.view.form</field>

<field name="arch" type="xml">
<xpath expr="//field[@name='order_line']/form//field[@name='price_unit']" position="after">
<field name="x_sale_margin_percent" groups="base.group_user"/>
</xpath>
</field>
</record>
<record model="ir.ui.view" id="sale_margin_percent_2">
<field name="name">sale.order.line.tree.margin.view.form</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']/tree//field[@name='price_unit']" position="after">
<field name="x_sale_margin_percent" groups="base.group_user"/>
</xpath>
</field>
</record>
</data>
</openerp>
