创建一个新按钮以更改新学生的状态

Question

我有一个问题，创建一个新的按钮，以改变一个新学生的状态。

首先我创建了一个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>
...

接下来，我创建了一个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()

然后创建一个init.py文件：

import sim

最后，我创建了一个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': [],
}

但是，当我执行代码时，它会产生以下错误消息：

No handler found.

这是来自控制台的错误：

错误似乎来自"def setuju(.“)。我的剧本怎么了？

Answer 1

如果您的模块没有证书，请从openerp文件中删除密钥“证书”。另外，请从setuju()函数中删除工作流。我没有看到为您的类定义的工作流。

从日志中，错误是因为缩进错误。请检查def setuju()前有正确的空格数

Answer 2

要在OpenERP上进行开发，即使您有使用它的经验，您也会经常发现这样的情况。必须了解日志文件的位置，检查它们是否有错误。

这将取决于您如何安装服务器，但根据文档，它应该在C:\Program Files\OpenERP X.X\Server\openerp-server.log.上。如果没有，请在服务器配置文件中查找。

如果您对OpenERP开发很认真，我建议您：

1. 停止服务器服务并在控制台终端中手动启动它。它不仅为您提供有关警告和错误的即时信息，而且还将显示python print语句的结果，并让您进入(Pdb) 调试模式。
2. 安装您的Ubuntu中的OpenERP服务器 VM。它可能有一个学习曲线使用Linux，但有很多帮助，从长远来看，你会发现更容易获得帮助和解决问题的平台。
