服務器操作的工作流程在Odoo 9.1上不起作用

Question

我一直在用this tutorial構建Odoo 9.1模塊。但是，我創建了由該指令的工作流程不工作（當我點擊確認按鈕，沒有任何反應，沒有錯誤日誌等）

下面是相關的代碼：

models.py（在Session類）

state = fields.Selection([ 
    ('draft', "Draft"), 
    ('confirmed', "Confirmed"), 
    ('done', "Done"), 
]) 

@api.multi 
def action_draft(self): 
    self.state = 'draft' 

@api.multi 
def action_confirm(self): 
    self.state = 'confirmed' 

@api.multi 
def action_done(self): 
    self.state = 'done' 

academy.xml（在會話形式報頭）

<header> 
    <button name="action_draft" type="workflow" 
      string="Reset to draft" 
      states="confirmed,done"/> 
    <button name="action_confirm" type="workflow" 
      string="Confirm" states="draft" 
      class="oe_highlight"/> 
    <button name="action_done" type="workflow" 
      string="Mark as done" states="confirmed" 
      class="oe_highlight"/> 
    <field name="state" widget="statusbar"/> 
</header> 

session_workflow.xml

出了什麼問題？根據信號值

Answer 1

改變按鈕名稱

代碼：

<field name="signal">draft</field> 
<button name="action_draft"... 

變「action_draft」到「草案」

單擊該按鈕時，它會發送按鈕名稱一個信號，所以它們必須是相同的。
