OpenERP 物件可以从 PostgreSQL 的窗体创建产生。方式如下:

  1. 宣告你的栏位 _columns 定义。所有字段必须有 readonly=True. 的旗标。

  2. Specify the parameter _auto=False to the OpenERP object, so no table corresponding to the _columns dictionnary is created automatically.

  3. 增加一个方法 init(self, cr) 用来创建一个符合 _columns 栏位定义的 PostgreSQL 窗体 .

范例 report_crm_case_user 这个物件是依照以下模式创建的

  1. class report_crm_case_user(osv.osv):
  2.    _name = "report.crm.case.user"
  3.    _description = "Cases by user and section"
  4.    _auto = False
  5.     _columns = {
  6.    'name': fields.date('Month', readonly=True),
  7.    'user_id':fields.many2one('res.users', 'User', readonly=True, relate=True),
  8.    'section_id':fields.many2one('crm.case.section', 'Section', readonly=True, relate=True),
  9.    'amount_revenue': fields.float('Est.Revenue', readonly=True),
  10.       'amount_costs': fields.float('Est.Cost', readonly=True),
  11.    'amount_revenue_prob': fields.float('Est. Rev*Prob.', readonly=True),
  12.    'nbr': fields.integer('# of Cases', readonly=True),
  13.       'probability': fields.float('Avg. Probability', readonly=True),
  14.    'state': fields.selection(AVAILABLE_STATES, 'State', size=16, readonly=True),
  15.    'delay_close': fields.integer('Delay to close', readonly=True),
  16.    }
  17.     _order = 'name desc, user_id, section_id'
  19.    def init(self, cr):
  20.    cr.execute("""
  21.         create or replace view report_crm_case_user as (
  22.             select

  38.    report_crm_case_user()
