Retrieve a Field using Related to select a Selection Field

Question

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.pi

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

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' )

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 !
