創建一個新按鈕來更改新學生的狀態

Question

我在創建新按鈕以更改新學生的狀態時遇到問題。

首先我創建了一個XML文件：

... 
<record model="ir.ui.view" id="student_form"> 
<field name="name">sim.student.form</field> 
<field name="model">sim.student</field> 
<field name="type">form</field> 
<field name="arch" type="xml"> 
<form string="Student"> 
<field name="name"/> 
<field name="student_name"/> 
<field name="father_name"/> 
<field name="gender"/> 
<field name="contact_no"/> 
<button name="setuju" states="draft" string="Approve" type="object"/> 
</form> 
</field> 
</record> 
... 

接下來，我創建了一個Python文件：

from osv import fields, osv 
import time 
import netsvc 
import pooler 

class sim_student(osv.osv): 
    _name = "sim.student" 
    _description = "Data Siswa" 

    def setuju(self, cr, uid, ids, context=None): 
     workflow = netsvc.LocalService('workflow') 

     for name in ids: 
      workflow.trg_create(uid, self._name, name, cr) 

     return self.write(cr, uid, ids, {'state': 'confirmed'}, context=context) 

    _columns = { 
     'name': fields.char('Registration Number',size=256,required=True), 
     'student_name': fields.char('Student Name',size=256,required=True), 
     'father_name': fields.char('Father Name',size=256), 
     'gender':fields.selection([('male','Male'),('female','Female')],'Gender'), 
     'contact_no':fields.char('Contact Number',size=256), 
     'state': fields.selection([('new', 'New'), \ 
            ('confirmed', 'Received'), \ 
            ('cancelled', 'Cancelled')], \ 
           'Status', readonly=True, select=True) 
    } 

sim_student() 

然後我createe的初始化 .py文件：

import sim 

最後，我創建了一個openerp .py文件：

{ 
'name': 'Student Information Management', 
'version': '0.1', 
'category': 'Tools', 
'description': """Data Siswa.""", 
'author': 'Wasis Lukito', 
'summary': 'Test, Test, dan Test', 
'website': 'http://wasis.wordpress.com/', 
'depends': ['base'], 
#'init_xml': [], 
#'update_xml': ['sim_view.xml'], 
#'demo_xml': [], 
#'installable': True, 
'data': ['sim_view.xml',], 
'css':['static/src/css/lunch.css'], 
'demo': [], 
'installable': True, 
'application' : True, 
'certificate' : '001292377792581874189', 
'images': [], 
} 

當我執行的代碼，但是，它產生此錯誤消息：

No handler found. 

這是從控制檯錯誤：

的錯誤似乎來自「def setuju（...」）。我的腳本有什麼問題？

Answer 1

請從openerp文件中刪除鑰匙'證書'如果你的模塊沒有證書。另請從setuju()功能中刪除工作流程。我沒有看到爲你的班級定義的工作流程。

從日誌中發現錯誤是因爲縮進錯誤。請檢查您是否有正確的空格數量def setuju()

Answer 2

要在OpenERP上開發，即使有經驗，您也會經常發現類似情況。這是一個必須瞭解你的日誌文件檢查他們的錯誤。

這將取決於您如何安裝服務器，但根據documentation它應該在C:\Program Files\OpenERP X.X\Server\openerp-server.log.。如果沒有，請在服務器配置文件中查找它。

如果你是認真的OpenERP發展，我會建議你：

1. 停止服務器服務，並在控制檯端手動啓動它來代替。它不僅爲您提供有關警告和錯誤的即時信息，而且還會顯示python print聲明的結果，並讓您進入(Pdb)debug mode。

2. 安裝您的OpenERP server in an Ubuntu Server虛擬機。它可能有使用Linux的學習曲線，但有很多可用的幫助，從長遠來看，您會發現在該平臺上獲得幫助和解決問題要容易得多。
