Odoo10.0中的工做流

Odoo10.0中能夠經過兩種方式來實現工做流（workflow）

　　一種的官網API中給出的方式，連接：https://www.odoo.com/documentation/10.0/reference/workflows.html

　　還有一種是經過查看Odoo10.0的源碼，發現自帶模塊中使用的方式；

先來講下第一種方式：

首先，建立文件目錄：

　　

接下來編寫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'工做流請假測試'

    name = fields.Char(u'請假說明')
    start_date = fields.Datetime(u'開始時間')
    end_date = fields.Datetime(u'結束時間')

    state = fields.Selection(
        [
            ('init', u'初始'),
            ('start', u'開始'),
            ('confirm', u'確認'),
            ('complete', u'完成'),
        ],
        default='init',
        string=u'狀態',
        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'

}

使用這種方式定義workflow，FromView中有兩處須要注意：

　　1.button中的name屬性對應workflow.transition中的signal；

　　2.button的type屬性必須設置爲workflow，不然會報錯;

 

接下來第二種方式定義workflow，這種方式相比較第一種方式，要簡單一些

原理是直接在button中調用model中定義的方法來修改state的狀態，可是此處button的type屬性須要定義爲object

具體以下：

__mainfest__.py文件中註釋掉該行

# 'views/leave_workflow.xml',

view.xml中須要將header中的button坐下調整：

<header>
　　<button name="do_start" states="init" string="開始" groups="workflow_demo.workflow_leave_group_employee" type="object" class="oe_highlight"/>
　　<button name="do_confirm" states="start" string="確認" 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屬性爲model中的方法，type屬性修改成object，其餘不用修改。

 

以上兩種方式我本身都本地驗證過，是沒有問題的，有疑問的夥伴能夠留言

 

你們共同窗習，共同進步
