Odoo 9中的工作流

Question

我创建了一个具有fieldstate的模块，它具有以下属性“draft”、“open”、“paid”、“cancel”。在xml中，我有一个按钮confirm，当用户单击此按钮时，状态必须从“draft”更改为“open”。但是，代码不起作用，状态不变。有什么线索吗？ 谢谢

以下是我的代码：

（一）模块.py在

'state': fields.selection([('draft', "New"), ('open', "Awaiting Payments"), ('paid', "Paid"), ('cancel', "Cancelled")], 'Status', default='draft', track_visibility='onchange'),

def action_draft(self, cr, uid, ids, context=None):
        return self.write(cr, uid, ids, {'state':'draft'})

def action_open(self , cr, uid, ids, context=None):
        return self.write(cr, uid, ids, {'state':'open'})

def action_paid(self , cr, uid, ids, context=None):
        return self.write(cr, uid, ids, {'state':'paid'})

def action_cancel(self , cr, uid, ids, context=None):
        return self.write(cr, uid, ids, {'state':'cancel'})

（二）模块.xml在

（三）工作流.xml在
