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'
view.xml文件：
<odoo> <data> <record model="ir.ui.view" id="workflow_demo.list"> <field name="name">workflow_demo list</field> <field name="model">workflow_demo.leave</field> <field name="arch" type="xml"> <tree> <field name="name"/> <field name="start_date"/> <field name="end_date"/> <field name="state"/> </tree> </field> </record> <record model="ir.ui.view" id="workflow_demo.form"> <field name="name">workflow_demo form</field> <field name="model">workflow_demo.leave</field> <field name="arch" type="xml"> <form string="请假单"> <header> <button name="leave_start" states="init" string="开始" groups="workflow_demo.workflow_leave_group_employee" type="workflow" class="oe_highlight"/> <button name="leave_confirm" states="start" string="确认" groups="workflow_demo.workflow_leave_group_manager" type="workflow" class="oe_highlight"/> <button name="leave_complete" states="confirm" string="完成" groups="workflow_demo.workflow_leave_group_leader" type="workflow" class="oe_highlight"/> <field name="state" widget="statusbar" statusbar_visible="start,confirm,complete"/> </header> <group> <field name="name"/> <field name="start_date"/> <field name="end_date"/> </group> </form> </field> </record> <record model="ir.actions.act_window" id="workflow_demo.action_window"> <field name="name">workflow_demo window</field> <field name="res_model">workflow_demo.leave</field> <field name="view_mode">tree,form</field> <field name="help" type="html"> <p class="oe_view_nocontent_create">创建请假单</p> </field> </record> <!-- Top menu item --> <menuitem name="workflow_demo" id="workflow_demo.menu_root"/> <!-- menu categories --> <menuitem name="Menu 1" id="workflow_demo.menu_1" parent="workflow_demo.menu_root"/> <!-- actions --> <menuitem name="List" id="workflow_demo.menu_1_list" parent="workflow_demo.menu_1" action="workflow_demo.action_window"/> </data> </odoo>
leave_security.xml文件：
<?xml version="1.0" encoding="utf-8" ?> <odoo> <!-- noupdate 0,升级模块时更新数据 1,只在安装时创建数据,开发时可设置为0，定版后改回1 --> <data noupdate="0"> <record id="model_workflow_leave_category" model="ir.module.category"> <field name="name">请假管理</field> </record> <record id="workflow_leave_group_employee" model="res.groups"> <field name="name">团队成员</field> <field name="category_id" ref="model_workflow_leave_category"/> <field name="implied_ids" eval="[(4, ref('base.group_user'))]"/> <field name="comment">团队成员</field> </record> <record id="workflow_leave_group_manager" model="res.groups"> <field name="name">项目经理</field> <field name="category_id" ref="model_workflow_leave_category"/> <field name="implied_ids" eval="[(4, ref('workflow_demo.workflow_leave_group_employee'))]"/> <field name="comment">项目经理</field> </record> <record id="workflow_leave_group_leader" model="res.groups"> <field name="name">领导</field> <field name="category_id" ref="model_workflow_leave_category"/> <field name="implied_ids" eval="[(4, ref('workflow_demo.workflow_leave_group_manager'))]"/> <field name="users" eval="[(4, ref('base.user_root'))]"/> <field name="comment"></field> </record> </data> </odoo>
ir.model.access.csv文件：
id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink

leave_workflow.xml文件：

__mainfest__.py文件：
# -*- coding: utf-8 -*- { 'name': "工作流Demo", 'summary': """ 工作流测试 """, 'description': """ Long description of module's purpose """, 'author': "ed", 'website': "http://www.yourcompany.com", 'category': 'Uncategorized', 'version': '0.1', 'application': True, # any module necessary for this one to work correctly 'depends': ['base'], 'sequence': 10, # always loaded 'data': [ 'security/leave_security.xml', 'security/ir.model.access.csv', 'views/leave_workflow.xml', 'views/views.xml', ], # only loaded in demonstration mode 'demo': [ ], }
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
大家共同学习，共同进步
