How to use selection on many2one?

Question

As described here [1] , I have created a many2one field with custom selection function:

def _buyer_selection(self, cr, uid, context=None):
partner_obj = self.pool.get('res.partner');
res = [];
partner_ids = partner_obj.search(cr, uid, [('buyer','=',True)]);
for partner in partner_obj.browse(cr, uid, partner_ids, context=context):
res.append((partner.id, partner.buyer_code))
return res;
_columns = {
'buyer_id': fields.many2one('res.partner', 'Buyer', selection=_buyer_selection),
}

But in the vi

Solved as prakash suggested.

Overriding name_get

def name_get(self, cr, uid, ids, context=None):
    if context.get('view_buyer_code', False):            
        res = [];
        for partner in self.browse(cr, uid, ids, context=context):
            res.append((partner.id, partner.buyer_code));
    else:
        res = super(res_partner_x, self).name_get(cr, uid, ids, context=context);
    return res;

And using context to control the viewed name

<field name="buyer_id" domain="[('buyer','=',True)]" context="{'view_buyer_code': True}"></field>

Only Disadvantage: After selectiong the Buyer the normal Partner name is displayed.
But I guess I can live with that.
