您可以使用服务器操作来实现此目的。您可以通过访问设置»技术»操作»服务器操作或在模块上创建XML来在OpenERP中创建服务器操作。
我将在此处留下一个服务器操作的示例，当我正在开发的模块上的对象达到特定状态时，我将使用该服务器操作向用户发送电子邮件：
<?xml version="1.0" encoding="UTF-8"?>
<openerp>
<data>
<record id="ir_actions_server_send_email_when_closed_nconf" model="ir.actions.server">
<field name="name">Auto-email when request is closed, not confirmed</field>
<field name="model_id" ref="model_generic_request"/>
<field name="state">email</field>
<field name="type">ir.actions.server</field>
<field name="condition">True</field>
<field name="email">object.requestor.email</field>
<field name="subject">Your request object.name has been closed (not confirmed)</field>
<field name="message"><![CDATA[
THIS IS AN AUTOMATED EMAIL. DO NOT REPLY.
Hello,
We are here to inform you that the request [[object.name]] you submitted on [[object.request_date]] with the following data:
| Request - Details
|=========================
| Number: [[object.id]]
|=========================
| Responsible Person: [[object.responsible_name.name]]
| Request description: [[object.request_description]]
| Stating reasons: [[object.stating_reasons]]
|=========================
| Notes: [[object.notes]]
Has not been confirmed and is closed.
If you have any question, do not hesitate to contact your supervisor.
Thank you!]]>
</field>
</record>
</data>
</openerp>
此操作是从工作流中调用的。就您而言，您可以在保存表单时调用它（状态=草稿，也许？）。
因此，您必须在工作流活动定义中添加对服务器操作的调用：
<record model="workflow.activity" id="act_closed_nconf">
<field name="wkf_id" ref="wkf_request" />
<field name="name">request_closed_nconf</field>
<field name="action_id" ref="ir_actions_server_send_email_when_closed_nconf"/>
<field name="kind">function</field>
<field name="action">close_nconf_request()</field>
<field name="flow_stop">True</field>
</record>
希望这可以帮助！
------ 对更扩展的答案进行一点编辑-----
好的，我会尝试做一个短片几乎功能齐全例子。
在您的 python 文件中（如果尚未添加），您必须添加一些状态才能使工作流程正常运行。
class whatever(osv.osv):
_name='whatever'
_description='whatever'
_columns={
'name': fields.char('whatever', size=64, required=True),
'state': fields.selection([('draft','Draft'),
('sent','Sent'),
('closed','Closed'),
],
'Status', readonly=True, track_visibility='onchange',
),
(... some other fields in here...)
}
_defaults={
'state': 'draft',
}
#these 3 functions are called by the workflow
def draft(self, cr, uid, ids, context=None):
self.write(cr, uid, ids, {'state': 'draft'})
return True
def send(self, cr, uid, ids, context=None):
self.write(cr, uid, ids, {'state': 'sent'})
return True
def close(self, cr, uid, ids, context=None):
self.write(cr, uid, ids, {'state': 'closed'})
return True
whatever()
然后，您必须有一个适用于您的对象的工作流定义，这将是您的 xml 的内容：
<?xml version="1.0"?>
<openerp>
<data>
<record model="workflow" id="wkf_whatever">
<field name="name">whatever.wkf</field>
<field name="osv">whatever</field>
<field name="on_create">True</field>
</record>
<!-- activities -->
<record model="workflow.activity" id="act_draft">
<field name="wkf_id" ref="wkf_whatever" />
<field name="flow_start">True</field>
<field name="name">draft</field>
<field name="action_id" ref="send_automatic_email"/>
<field name="kind">function</field>
<field name="action">draft()</field>
</record>
<record model="workflow.activity" id="act_send">
<field name="wkf_id" ref="wkf_whatever" />
<field name="name">send</field>
<field name="kind">function</field>
<field name="action">send()</field>
</record>
<record model="workflow.activity" id="act_close">
<field name="wkf_id" ref="wkf_whatever" />
<field name="flow_stop">True</field>
<field name="name">close</field>
<field name="kind">function</field>
<field name="action">close()</field>
</record>
<!-- transitions -->
<record model="workflow.transition" id="whatever_t1">
<field name="act_from" ref="act_draft" />
<field name="act_to" ref="act_send" />
<field name="signal">draft</field>
</record>
<record model="workflow.transition" id="whatever_t2">
<field name="act_from" ref="act_send" />
<field name="act_to" ref="act_close" />
<field name="signal">close</field>
</record>
</data>
</openerp>
线路<field name="action_id" ref="send_automatic_email"/>在活动声明中调用 ID 为“send_automatic_email”的服务器操作
还有你的动作服务器：
<?xml version="1.0" encoding="UTF-8"?>
<openerp>
<data>
<record id="send_automatic_email" model="ir.actions.server">
<field name="name">Send automatic email</field>
<field name="model_id" ref="model_whatever"/>
<field name="state">email</field>
<field name="type">ir.actions.server</field>
<field name="condition">True</field>
<field name="email">object.requestor.email</field>
<field name="subject">Your whatever: object.name has been created</field>
<field name="message"><![CDATA[
THIS IS AN AUTOMATED EMAIL. DO NOT REPLY.
Hello,
bla bla bla bla
In here you will write whatever you want, and can access to data stored in your database with, for example [[object.name]] to access the field "name"
</field>
</record>
</data>
</openerp>
有了这 3 个文件（以及其中的一些更改！），您应该能够做您想做的事情。
不要忘记，您必须重新启动 OpenERP 服务器（以便重新编译 python 文件中的更改）并更新模块以加载 XML 文件！
祝你好运！

差点忘了！
在 xml 视图文件中，您必须在表单视图中添加这些按钮才能调用工作流程操作：
<header>
<button name="send" class="oe_highlight" string="Send" type="workflow" states="draft"/>
<button name="close" class="oe_highlight" string="Close" type="workflow" states="sent"/>
<field name="state" widget="statusbar" statusbar_visible="draft,sent,closed" />
</header>
