Help creating model data in O12

Hello, I am trying to understand how model creation works in odoo 12. I have used the scaffold tool, which has a model called 'test_module.test_module', and in the data xml you create rows using model="test_module.test_module".

This works fine, but I cannot figure out how to add a second model. When I copy that model and change the name to test_module.test_module2, I get a key error:

odoo.tools.convert.ParseError: "test_module.test_module2" while parsing /mnt/extra-addons/test_module/data/data.xml:9, near

Could you please help me understand why?

Here is the original model:

[code]

from odoo import models, fields, api

class test_module(models.Model):

_name = 'test_module.test_module'

name = fields.Char()

[/code]

and here is the new model:

[code]

from odoo import models, fields, api

class test_module2(models.Model):

_name = 'test_module.test_module2'

name = fields.Char()

[/code]

Here is __init__.py in the models folder:
[code]

from . import models

from . import models2
[/code]

and here is the entire data xml:
[code]

<odoo>

<data>

<field name="name">Object 0</field>

</record>

<field name="name">Object 1</field>

</record>

</data>

</odoo>

[/code]

I went through the new module tutorial, but I cannot figure out the naming convention for model class names, or the _name attribute. Clearly I am missing something!

Thank you.

Are you sure it worked with only 1 module? Your models.py file don't have a field for value. In your xml file, you're calling a field variable called value, but it's not delcared in your python file

<field name="value">10</field> [you're calling value here, but your python field don't have that field called value.

Try this (hopefully it'll work for you):

class test_module(models.Model):

_name = 'test_module.test_module'

name = fields.Char()

value= fields.Char()

class test_module2(models.Model):

_name = 'test_module.test_module2'

name = fields.Char()

value= fields.Char()

So basically your xml file is calling your python class for the field names. If your xml file is calling a field that's not defined, it wont work.

Thank you, good point... I snipped the paste to only show the _name! Here is the full trace. I don't understand why the first model works, and the second one doesn't, when all I changed is the name.

Hi,

As per your code , this what i found

class test_module2(models.Model):

_name = 'test_module.test_module2'

name = fields.Char() /Exist in data file But No value field/

<field name="name">Object 1</field>

<field name="value">10</field>

</record>

<field name="value"> this does not exist in your model.

Regards,
Silvestar
