first you must have to give many2one relation ship in source object (table)

'fieldname_ids': fields.one2many('ObjectName', 'fieldname_id', 'Label', help='Help note'),

syntax is as above:

Object name : give model name or table name

fieldname_id : give many2one filed name of Object Name

Lable: lable to display

Hi,

Refer the following example if it may help you:

class order(osv.osv):
_description = "Orders"
_name = "order.order"
_columns = {
'line_ids': fields.one2many('order.line','ordr_id',"Order Lines"),
}
order()

class order_line(osv.osv):
_description = "Order Line"
_name = "order.line"

_columns = {
'ordr_id': fields.many2one('order.order', 'Order ID'),
}

order_line()

If you are creating one2many field related to object2, object2 should have many2one field which is used in one2many field rel
