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'

view.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
