Simple Custom App crashes Odoo (Model '' does not exist in registry)

I've created a simple module to extend stock.production.lot model, so I would be able to attach some extra information to each product via unique Serial Number. I'm only starting to work with Odoo and this is an early version of a module I would use..

Extra question: how would I make products searchable by these fields I added? I.e. if I wanted to find a product with 'Full' Toner Level.

The module:

from odoo import models, fields, api

class x_wh(models.Model):

_name = "stock.production.lot"

_inherit = 'stock.production.lot'

x_toner = fields.Char(

'Toner Level', index=True

)

x_print_count = fields.Integer(

'Print Count', index=True

)

x_description = fields.Text(

'Description'

)

x_condition = fields.Char(

'Product Condition', index=True

)

<odoo>

<data>

<field name="model">stock.production.lot</field>

</field>

</record>

<field name="model">stock.production.lot</field>

</field>

</record>

</data>

</odoo>

The module installs without any errors, but if I reload Odoo it crashes with the error I include here.



  File "C:\Projects\Odoo2\odoo\odoo\modules\loading.py", line 274, in load_marked_modules
    perform_checks=perform_checks, models_to_check=models_to_check
  File "C:\Projects\Odoo2\odoo\odoo\modules\loading.py", line 146, in load_module_graph
    model_names = registry.load(cr, package)
  File "C:\Projects\Odoo2\odoo\odoo\modules\registry.py", line 250, in load
    model = cls._build_model(self, cr)
  File "C:\Projects\Odoo2\odoo\odoo\models.py", line 428, in _build_model
    raise TypeError("Model %r does not exist in registry." % name)

Hi,

Make sure that the stock module is added in the depends on the custom module. And also do one thing,

class XWH(models.Model):
    _name = "stock.production.lot"
    _inherit = 'stock.production.lot'

remove the name from the above class and make it like this,

class XWH(models.Model):
    _inherit = 'stock.production.lot'

Thanks

If you use
_inherit : It will use the same table that you mention in the quotes.

Class SaleOrder(models.Model):
_inherit = 'sale.order'

_name : It will create a new table.

Class SaleOrder(models.Model):
_name = 'new.table.name'

If you create a class with both _name and _inherit: It will generate a new table with the name. table contains all the fields and property that we inherit.

Class SaleOrder(models.Model):
_name = 'new.table.name'
_inherit = 'sale.order'

Thanks

Thanks, that worked. I didn't realise that any time I am extending a certain class I need to make a reference in the manifest..

What does the removal of the name do in the module?
