Odoo⼯作流介绍及代码⽰例
本⽂主要介绍了Odoo⼯作流的开发⽅法并提供代码⽰例
新版本的odoo开始减少workflow的使⽤，推荐使⽤workflow-ish的⽅式来处理⼯作流过程。从odoo11起已经完全移除了⼯作流引擎的相关代码。
春天的故事在odoo中,workflow是关联到某个model的对象,⽤来动态的管理记录的⽣命周期.
创建模拟的workflow-ish
状态的改变流程如下
Draft -> Confirmed
Confirmed -> Draft
Confirmed -> Done
Done -> Draft
添加代码的步骤
1 添加state字段
2 添加state状态转移⽅法，并绑定⽅法到form view上的按钮
3 添加相关按钮到form view
odoogoedu/models.py
state = fields.Selection([('draft', "Draft"),('confirmed', "Confirmed"),('done', "Done")], default='draft')
@api.multi
def action_draft(lf):
lf.state = 'draft'
@api.multi
def action_confirm(lf):
lf.state = 'confirmed'
@api.multi
def action_done(lf):
lf.state = 'done'

使⽤odoo workflow管理状态(废弃)
以上没有使⽤odoo workflow对象。odoo中的workflow使⽤xml定义，在workflows中有activities (nodes or actions) ,transitions (conditions)和workitems。
Activities定义了⼀些由odoo服务器所要完成的任务，如改变记录状态，发送邮件
Transitions定义了如何从⼀个Activity到另外Activity
注意
workflow是在关联的model对象创建时⼀起创建并运⾏的。
替换ssion workflow
替换刚才临时的（ad-hoc）ssion workflow到⼀个真正的workflow对象. 并且改变button的绑定⽅法到workflow的transition⽅法
去除state的default值，交由workflow管理。

杂然相许的许创建的workflow可以在Settings ‣ Technical ‣ Workflows ‣ Instances⾥查看
button name="transition signal 名称"
⾃动执⾏transition
根据条件⾃动执⾏transition，当课时的上课⼈数⼤于50%的时候⾃动从草稿到确认状态。openacademy/views/l
