Thank you for the answers. Using Odoo Online I believe I cannot edit Python Code but xml? Could you please describe me how to access the code?

Hi,

Odoo's best practice for controlling field visibility/editability per group is via XML view customization — using the groups attribute (to restrict visibility to groups), and attrs for making the field read-only dynamically.

Hide/Make Read-Only for Sales users:

<field name="property_account_position_id"

       groups="account.group_account_user,account.group_account_manager"

       attrs="{'readonly': [('groups_id', 'not in', [ref('account.group_account_manager'), ref('account.group_account_user')])]}" />

The field is only shown to users in the Accounting groups via groups attribute.

It is read-only for users who are not in those groups.

Sales users won't see it (if they're not part of accounting groups).

This method keeps the logic clean and group-based, and doesn't require creating custom boolean fields or computed conditions.

i hope it is usefull

Hi,

Please refer to the code below:

Python

from odoo import models, fields, api

class ResPartner(models.Model):
    _inherit = 'res.partner'

    is_account_user = fields.Boolean(
        string="Is Accounting User",
        compute='_compute_is_account_user',
        store=False
    )

    @api.depends_context('uid')
    def _compute_is_account_user(self):
        for record in self:
            user = self.env.user
            record.is_account_user = user.has_group('account.group_account_user') or user.has_group('account.group_account_manager')

XML:

<record id="view_partner_form" model="ir.ui.view">
    <field name="name">res.partner.view.form</field>
    <field name="model">res.partner</field>
    <field name="inherit_id" ref="base.view_partner_form"/>
    <field name="arch" type="xml">
        <xpath expr="//field[@name='property_account_position_id']"
               position="before">
            <field name="is_account_user" invisible="1"/>
        </xpath>
        <xpath expr="//field[@name='property_account_position_id']"
               position="attributes">
           <attribute name="readonly">not is_account_user</attribute>
        </xpath>
    </field>
</record>

Hope it helps.
