ORM Methods in OpenERP

Every object in OpenERP is based on OSV i.e Object Service and this service implements full Object-Relational Mapping enabling developers not to worry for the simple SQL operations.

In OpenERP, we have such ORM methods that are very useful. Here are the few basic methods:

1. read(cr, uid, ids, fields=None, context=None): returns a list of dictionaries with field values.
1. res = self.read(cr, uid, [5,6],['name', 'partner_id'])
2. print 'Partner:', res[0]['partner_id']
2. write(cr, uid, ids, values, context=None): updates a record with provided values.
3. search(cr, uid, values, args, offset=0, limit=None, order=None, context=None, count=False): returns list of ids (tuple) on search criteria
