The Current Setup

I am attempting to load default data into a module I am designing.  To do so, I have my model setup in cra_model.py, and the default data setup in cra_data.xml  which is referenced in my __manifest__.py as such:

{
     ...
     'data': ['data/cra_data.xml'],
     ...
}

Here are the contents of my models and data files.

cra_model.py
# -*- encoding: utf-8 -*-
from odoo import models, fields, api
class CraCats(models.Model):
     _name = 'cra.cat'
     name = fields.Char('CRA Category')
     type = fields.Selection(
         [('in','Income'), ('out','Expense')],
         string='Income or Expense?')


cra_cat_data.xml
<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <record id="cra_cat_a" model="cra.cat">
        <field name="name">Income from sales</field>
        <field name="type">in</field>
    </record>
    <record id="cra_cat_b" model="cra.cat">
        <field name="name">Purchases for sales</field>
        <field name="type">out</field>
    </record>
</odoo>

The Problem at Hand

I am able to install the module just fine without the data file reference in the __manifest__.py.  As soon as I add the data file reference back, and attempt an install or upgrade of the module, I receive the following traceback on the server.  The webui merely gets stuck in a loading state.

What am I missing?  Where have I gone wrong?

In above given code, there is no errors i think. The error is from xml file, you can check the line number mentioned in the error. probably it may be missing of something or misplaced thing in the XML. check the line 16 and column 29

Ok. I looked into my XML deeper, and saw an & instead of an &amp; the XML was generated from an excel spreadsheet, and I forgot to check for &s.

Hi Andrew,


Here's the start of my Odoo 10 data file (which works). I think you forgot the <data> tag. Close it as well :-)

NB. noupdate ensures that the data, once changed by a user, are not overwritten when you update the module.


Bart

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data noupdate="1">
    	<record model="property_management.subdivision_type" id="type_office">
            <field name="name">Office</field>
            <field name="sequence">1</field>
        </record>

Bart, thanks for the info. However, "[t]he <odoo> top element in data files was introduced in version 9.0 and replaces the former <openerp> tag. The <data> section inside the top element is still supported, but it is now optional. In fact, now <odoo> and <data> are equivalent, so we could use either one as top elements for our XML data files." <<Odoo 10 Development Essentials, Daniel Reis, pg 84>> This is to say that <odoo> and <data> are now interchangeable top elements. There is no longer the need to place the <data> element between <odoo> and <record>. In your provided example, you could also get away with <odoo noupdate="1">. I am genuinely grateful for your desire to help me troubleshoot. My problem was, in the end, caused by a missing escape character. I had an ampersand(&) where I ought to have had the escape character equivalent (&amp;). Peace and all good! Proost!

Good that it was *only* a syntax issue. Odoo is not very good at pointing these things out, and we ourselves often look too far :-)
