odoo 在原有工作流中添加审批流

步骤：

1、加入所需的工作流节点以及相连的线（即所添加的审批流），代码如下：

 <?xml version="1.0" encoding="utf-8"?>
 <openerp>
     <data>
         <record id="hrp_sale_approve" model="workflow.activity">
             <field name="wkf_id" ref="sale.wkf_sale"/>
             <field name="name">HrpApproval</field>
             <field name="kind">function</field>
             <field name="action">start_base_workflow()</field>
         </record>

         <record id="trans_confirmed_hrp_approve" model="workflow.transition">
             <field name="act_from" ref="sale.act_draft"/>
             <field name="act_to" ref="hrp_sale_approve"/>
             <field name="signal">to_hrpApprove</field>
         </record>

         <record id="hrp_sale_approve_trans" model="workflow.transition">
             <field name="act_from" ref="hrp_sale_approve"/>
             <field name="act_to" ref="sale.act_router"/>
             <field name="condition">is_complete_approved</field>
             <field name="signal"/>
             <field name="group_id" ref=""/>
         </record>

         <record id="sale.trans_sent_router" model="workflow.transition">
             <field name="act_from" ref="sale.act_sent"/>
             <field name="act_to" ref="hrp_sale_approve"/>
             <field name="signal">to_hrpApprove</field>
         </record>
     </data>
 </openerp>

效果如下，

2、添加审批流的相关按钮

3、_state_selection函数的相关映射，不懂可参考前一篇博客

4、is_complete_approved 字段来自动控制工作流的走向

5、在state中添加等待审批状态

6、start_base_workflow函数启动审批流

7、重写相关审批流按钮，根据自己所需来重写

 # 取消
     @api.multi
     def action_cancel(self):
         for rec in self:
             rec.state = 'cancel'

     # 完成
     @api.multi
     def action_done(self):
         for rec in self:
             rec.state = 'done'

     # 批准逻辑
     @api.multi
     def action_approve(self):
         for rec in self:
             rec.state = 'approved'
         self.signal_workflow('to_hrpApprove')

     # 拒绝逻辑
     @api.multi
     def action_refuse(self):
         for rec in self:
             rec.state = 'draft'

     # 批准订单
     @api.model
     def complete_approve(self, requisition_id):
         requisition_order = self.browse(requisition_id)
         requisition_order.write({'is_complete_approved': True})

     # 拒绝订单
     @api.model
     def refuse_approve(self, requisition_id):
         requisition_order = self.browse(requisition_id)
         requisition_order.action_refuse()

     # 拒绝按钮逻辑
     @api.multi
     def order_refuse_task(self):
         if self.approve_task:
             wkf_task_obj = self.env['hrp.base.wkf.task']
             return wkf_task_obj.approve_note_view(self.approve_task.id, 'refuse')
         else:
             return True

     # 审批按钮逻辑
     @api.multi
     def order_approve_task(self):
         if self.approve_task:
             wkf_task_obj = self.env['hrp.base.wkf.task']
             return wkf_task_obj.approve_note_view(self.approve_task.id, 'approve')
         else:
             return True

8、action_button_confirm方法为提交订单按钮，按下后将跳到审批流执行审批

     def action_button_confirm(self, cr, uid, ids, context=None):
         self.signal_workflow(cr, uid, ids, 'to_hrpApprove')
         self.write(cr, uid, ids, {'state': 'confirmed'})
         return True

self.signal_workflow(cr, uid, ids, 'to_hrpApprove')：发送一个信号to_hrpApprove，则将自动执行到审批流。

self.write(cr, uid, ids, {'state': 'confirmed'}) ：将state状态改写为'confirmed'
