Openerp 7.0消息推送
在一个文档的state变化时,需要将变化情况告知关注用户,通过研究account.invoice的代码,发现是经过如下过程实现此功能的:
1、添加一个消息阶段:
<record id="mt_invoice_paid" model="mail.message.subtype"> <field name="name">paid</field> <field name="res_model">account.invoice</field> </record>
2、定义state变更时的触发函数:
def confirm_paid(self, cr, uid, ids, context=None): if context is None: context = {} self.write(cr, uid, ids, {'state':'paid'}, context=context) self.confirm_paid_send_note(cr, uid, ids, context=context) return True
3、send_note函数,注意subtype的定义,与第一步的定义相关联。
def confirm_paid_send_note(self, cr, uid, ids, context=None): for obj in self.browse(cr, uid, ids, context=context): self.message_post(cr, uid, [obj.id], body=_("%s <b>paid</b>.") % (self._get_document_type(obj.type)), subtype="account.mt_invoice_paid", context=context)
这样在state变化的时候,消息会通知给关注此文档的用户,同时不同的用户可以设置关注不同的消息变更。
