How send default value for field from view to other view - openerp-7

Question

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 does not 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"?>
<openerp>
<data>
<record model="ir.ui.view" id="view_container_form">
<field name="name">container.form</field>
<field name="model">container</field>
<field name="type">form</field>
<field name="arch" type="xml">
<form string="Container">
<field name="name" select="1"/>
<field name="calculation_id" context="{'default_container_id': active_id}" />
</form>
</field>
</record>
<record model="ir.actions.act_window" id="action_container">
<field name="name">Container</field>
<field name="res_model">container</field>
<field name="view_type">form</field>
<field name="view_mode">tree,form</field>
</record>
<menuitem name="Container/Container" id="menu_container"/>-->
<menuitem name="Container" id="menu_container_item" parent="menu_container" action="action_container"/>
<record model="ir.ui.view" id="view_calculation_form">
<field name="name">calculation.form</field>
<field name="model">calculation</field>
<field name="type">form</field>
<field name="arch" type="xml">
<form string="Calculation">
<field name="namefull" />
<field name="container_id" />
</form>
</field>
</record>
<record model="ir.actions.act_window" id="action_calculation">
<field name="name">Calculation</field>
<field name="res_model">calculation</field>
<field name="view_type">form</field>
<field name="view_mode">tree,form</field>
</record>
<menuitem name="Calculation" id="menu_calculation_item" parent="menu_container" action="action_calculation"/>
</data>
</openerp>

You are correct, OpenERP will not move data around for you -- you will need to modify your Python code to do it.
Oh, and you should name your tables with your model as well -- I'll use a fake model name of my_model:
class calculation(osv.Model):
_name = 'my_model.calculation'
_columns = {
'container_id' fields.many2one('my_model.container', 'Container'),
'namefull': fields.char('Name Full', size=32),
}
def create(self, cr, uid, values, context=None):
new_id = super(calculation, self).create(cr, uid, values, context=context)
self.pool.get('my_model.container').create(cr, uid, {'calculation_id':new_id, 'name':values['namefull'])
return new_id
And something similer to write() in case namefull is updated.
