Hello,

I have to create new custom_module that add fields to the hr_employees view.

One of the fields I have to view, is the private mobile number of the employee, which is exist now in the related res_partner model.

How can I get it in the new custom module? 

I tried to write like taht, but got the error:

Field `mobile` does not exist

model.py file:  

from odoo import models, fields, api


class hr_employees_custom(models.Model):
    _inherit = ['hr.employee']

    mobile = fields.Char(related='address_home_id.phone', related_sudo=False,
                         string="Private Mobile", groups="hr.group_hr_user")

views.xml file: 

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data>
        <record id="view_employee_form_custom_inherit" model="ir.ui.view" >
            <field name="name">hr.employee.custom.form.inherit</field>
            <field name="model">hr.employee</field>
            <field name="inherit_id" ref="hr.view_employee_form"/>
            <field name="arch" type="xml">
                <xpath expr="//page[@name='personal_information']" position="inside">
                    <group string="Phone">
                        <field name="phone" class="o_force_ltr" groups="hr.group_hr_user" string="Phone"/>
                        <field name="mobile" class="o_force_ltr" groups="hr.group_hr_user" string="Mobile"/>
                    </group>
                </group>
            </xpath>
