I'm very disappointed with myself having to ask this question, but after almost two wasted days....

I am creating my first module I have 

from osv import osv, fields
    class sale_pack_type(osv.Model):
    _inherit = 'sale.order'
    _columns = {
    'sale_pack_type': fields.selection((('a', 'A'), ('b', 'B'), ('c', 'C')), 'Sale Packaging Type'),
    }
    _defaults = {
        'sale_pack_type': 'a',
    }

Which works just dandy!

But when I try to retrieve the value using 

class ware_pack_type(osv.Model):
    _inherit = 'stock.picking.out'
    _columns = {
        'ware_pack_type': fields.related('sale_id', 'sale_pack_type', type='char', relation='sale.order', readonly=True, store=True, string='Packaging Type'),
    }

I get constant failure :( -

The best I can achieve is displaying 'Packaging Type' in the view and 'ware_pack_type' in the 'stock.picking.out' db, all values = NULL.

I've tried everything ...

type='selection', selection=(('a','A'),.....

with and without relation=...

type='one2many'

gone through hundreds of web pages

and many many more

Nothing works, pleeeeasssse help.

It seems to be wrong related field implementation, I am not sure but please check related field documentation. related filed can be use with self related field. please see documentation or batter example from blogs other than openerp docs.

Cheers Zahin - did you mean to say "related field CAN be used"? or did you mean "Cannot"?

The only example / commentary relating to field.related is about a bug but thats four years old, and suppose to be resolved https://bugs.launchpad.net/openobject-server/+bug/385117 - I'm off for a beer!

@Cameron: What I mean is exact given in answer 1, sale_id should require.

For correct work in related field you must define list of selection values one more. Working example will be:

from osv import osv, fields

PACKAGE_TYPE_SELECTION = [
    ('a', 'A'),
    ('b', 'B'),
    ('c', 'C')
]

class sale_pack_type(osv.Model):
    _inherit = 'sale.order'
    _columns = {
        'sale_pack_type': fields.selection(PACKAGE_TYPE_SELECTION, 'Sale Packaging Type'),
    }
    _defaults = {
        'sale_pack_type': 'a',
    }

class ware_pack_type(osv.Model):
    _inherit = 'stock.picking.out'
    _columns = {
        'sale_id': fields.many2one('sale.order', 'sale order'),
        'ware_pack_type': fields.related('sale_id', 'sale_pack_type', type='selection', selection=PACKAGE_TYPE_SELECTION, readonly=True, store=True, string='Packaging Type'),
    }

Create first py file:

class Book_return(models.Model):

_name = 'college.return'

statusbar_custom = fields.Selection([('new', 'New'), ('draft', 'Draft'), ('cancel', 'Cancel'), ('confirm', 'Confirm'), ('done', 'Done')])

Create second py file.I implement the another table selection field in my current table.In this example is helpful for u

class Book_form(models.Model):

_name = 'college.book'

stage_id=fields.Many2one('college.return',string='Stage ID')

     stage_state = fields.Selection(related='stage_id.statusbar_custom',string='Stage State')

it should be like this 

class ware_pack_type(osv.Model):
_inherit = 'stock.picking.out'
_columns = {
    'sale_id': fields.many2one('sale.order', 'sale order'),
    'ware_pack_type': fields.related('sale_id', 'sale_pack_type', type='selection', relation='sale.order', readonly=True, store=True, string='Packaging Type'),
}
ware_pack_type()

Above same for the stock.picking object

Hope It works !

Mark true on the answer if is correct

Thanks,
