Odoo Help


Why can't I uninstall a simple custom module adding a single field to the purchase.order Model and User Interface?

What am I doing wrong (using V10.0)?

Module adds one field to the purchase order form. When uninstalls it breaks the database.

model and view as follows:


# -*- coding: utf-8 -*-

from odoo import models

from odoo import fields

from odoo import api

class SMS(models.Model):
    _inherit = 'purchase.order'

    sms_project_code = fields.Integer('Project Code PRJ:', help="Enter SMS Project Code")


<?xml version="1.0" encoding="utf-8"?>


    <record id="smspurchase_order_form" model="ir.ui.view">

        <field name="name">purchase.order.form.inherit</field>

        <field name="model">purchase.order</field>

        <field name="inherit_id" ref="purchase.purchase_order_form"/>

        <field name="arch" type="xml">

            <!-- extended elements-->

            <field name="date_order" position="after">

                <field name="sms_project_code" />






Traceback as follows
