Taken from OpenERP wiki page , just in case you like me , may missed it!...
Open ERP objects can be created from `PostgreSQL views. The technique is as follows :
- Declare your _columns dictionary. All fields must have the flag readonly=True.
- Specify the parameter _auto=False to the Open ERP object, so no table corresponding to the _columns dictionnary is created automatically.
- Add a method init(self, cr) that creates a `PostgreSQL View matching the fields declared in _columns.
report_crm_case_user(osv.osv):
_name = "report.crm.case.user"
_description = "Cases by user and section"
_auto = False
_columns = {
'name': fields.date('Month', readonly=True),
'user_id':fields.many2one('res.users', 'User',
readonly=True, relate=True),
'section_id':fields.many2one('crm.case.section',
'Section', readonly=True, relate=True),
'amount_revenue': fields.float('Est.Revenue', readonly=True),
'amount_costs': fields.float('Est.Cost', readonly=True),
'amount_revenue_prob': fields.float('Est. Rev*Prob.', readonly=True),
'nbr': fields.integer('# of Cases', readonly=True),
'probability': fields.float('Avg. Probability', readonly=True),
'state': fields.selection(AVAILABLE_STATES, 'State',
size=16, readonly=True),
'delay_close': fields.integer('Delay to close', readonly=True),
}
_order = 'name desc, user_id, section_id'
def init(self, cr):
cr.execute("""
create or replace view report_crm_case_user as (

min(c.id) as id,
