hi  thank you in advance for any help or comments 

i need to create one2one relation in openerp7 i read many articles about this idea and i could to type  the following code 

problem is : that openerp7  doesnot send value from parent view (calculation)to child (container) 

this my code 

testproject.py :

from osv import fields,osv
class container(osv.osv):
    _name='container'
    _columns={
        'calculation_id': fields.many2one('calculation','Calculation'),
        'name': fields.char('Name', size=32),
        }
container()
class calculation(osv.osv):
    _name='calculation'
    _columns={
        'container_id': fields.many2one('container','Container'),
        'namefull': fields.char('Name Full', size=32),
        }
calculation()

xml code:

<?xml version="1.0"?>
