Odoo10.0中的工作流
Odoo10.0中可以通过两种方式来实现工作流（workflow）
一种的官网API中给出的方式，链接：https://www.odoo.com/documentation/10.0/reference/workflows.html
还有一种是通过查看Odoo10.0的源码，发现自带模块中使用的方式；
先来说下第一种方式：
首先，创建文件目录：
接下来编写model及XML文件：
model文件:
# -*- coding: utf-8 -*-
from odoo import models, fields, api
class WorkflowDemo(models.Model):
_name = 'workflow_demo.leave'
_description = u'工作流请假测试'
name = fields.Char(u'请假说明')
start_date = fields.Datetime(u'开始时间')
end_date = fields.Datetime(u'结束时间')
state = fields.Selection(
[
('init', u'初始'),
('start', u'开始'),
('confirm', u'确认'),
('complete', u'完成'),
],
default='init',
string=u'状态',
copy=False,
readonly=True,
)
@api.one
def do_start(self):
print '-' * 40
print 'do_start'
self.state = 'start'
@api.one
def do_confirm(self):
print '-' * 40
print 'do_confirm'
self.state = 'confirm'
@api.one
def do_complete(self):
print '-' * 40
print 'do_complete'
self.state = 'complete'

使用这种方式定义workflow，FromView中有两处需要注意：
1.button中的name属性对应workflow.transition中的signal；
2.button的type属性必须设置为workflow，否则会报错;
接下来第二种方式定义workflow，这种方式相比较第一种方式，要简单一些
原理是直接在button中调用model中定义的方法来修改state的状态，但是此处button的type属性需要定义为object
具体如下：
__mainfest__.py文件中注释掉该行
# 'views/leave_workflow.xml',
view.xml中需要将header中的button坐下调整：
<header> <button name="do_start" states="init" string="开始" groups="workflow_demo.workflow_leave_group_employee" type="object" class="oe_highlight"/> <button name="do_confirm" states="start" string="确认" groups="workflow_demo.workflow_leave_group_manager" type="object" class="oe_highlight"/> <button name="do_complete" states="confirm" string="完成" groups="workflow_demo.workflow_leave_group_leader" type="object" class="oe_highlight"/> <field name="state" widget="statusbar" statusbar_visible="start,confirm,complete"/> </header>
其中name属性为model中的方法，type属性修改为object，其他不用修改。
以上两种方式我自己都本地验证过，是没有问题的，有疑问的伙伴可以留言
