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>

<record id="view_production_lot_form" model="ir.ui.view">
<field name="model">stock.production.lot</field>
<field name="inherit_id" ref="stock.view_production_lot_form" />
<field name="arch" type="xml">
<field name="ref" position="after" >
<field name="x_toner" />
<field name="x_print_count" />
<field name="x_description" />
<field name="x_condition" />
</field>
</field>
</record>
<record id="view_production_lot_form_simple" model="ir.ui.view">
<field name="model">stock.production.lot</field>
<field name="inherit_id" ref="stock.view_production_lot_form_simple" />
<field name="arch" type="xml">
<field name="ref" position="after" >
<field name="x_toner" />
<field name="x_print_count" />
<field name="x_description" />
<field name="x_condition" />
</field>
</field>
</record>

</data>
</odoo>

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

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

Hi

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?
