I want to create grid view in the form view.

I have written the xml for the grid view. But I searched and see that for gird view it must have one2many field above the tree. What is the reason to give one2many field?

My codes are given below

.py

class vansdent(osv.osv):

_name = "vans.dent"

_description = "Vans Dent"

_rec_name = 'service'

_description = "Vals Dent"

_columns = {

'year': fields.many2one('dent.year', 'Year', required=True, select=True),

'make': fields.many2one('vals.make','Make', required=True),

'model': fields.many2one('car.model','Model', required=True, select=True),

'service': fields.char('Service ID', required=True),

'vcustomer':fields.many2one('res.partner', 'Customer', domain=[('customer', '=', True)], select=True),

'vin':fields.char('VIN'),

}

class vansdent_bill(osv.osv):

_name = "vansdent.bill"

_description = "Vans Dent"

_columns = {

'name': fields.char('Year', required=True),

'make': fields.char('Make', required=True),

'model': fields.char('Model', required=True),

'customer': fields.char('Customer', required=True),

'serviceid': fields.many2one('vans.dent', 'Service ID', select=True),

'vin':fields.char('VIN'),

'description':fields.char('Description'),

'part':fields.char('Part'),

'price':fields.char('Price'),

'quantity':fields.char('Qty'),

'labour':fields.char('Labour'),

'paint':fields.char('Paint'),

'other':fields.char('Other'),

}

def vansdent_service(self, cr, uid, ids, serviceid=False, context=None):

res = {}

if serviceid:

service_obj = self.pool.get('vans.dent')

rec = service_obj.browse(cr, uid, serviceid)

res = {'value': {'name': rec.year.name, 'model': rec.model.name, 'make': rec.make.name, 'customer':rec.vcustomer.name, 'vin':rec.vin}}

else:

res = {'value': {'name': False, 'model': False, 'make': False, 'customer': False, 'vin':False}}

return res

How should I set one2many field for this condition. Help me with a code?
