当我要卸载我自己的模块时，它给出了一个错误。 (OpenErp ver 7)在我的课上我也输入了不同的不同修改。但我没有清除所有这些东西并只保留下面的代码。请帮助我找出问题所在.. 现在当我尝试安装 address_book 模块时也发生了这个错误

  File "/home/priyan/Software/openerp-7.0-20130309-002120/openerp/modules/registry.py", line 218, in new
    openerp.modules.load_modules(registry.db, force_demo, status, update_module)

AttributeError: 'NoneType' object has no attribute '_table'

这是我的 view.xml 文件

<?xml version="1.0"?>
<openerp>
    <data>
        <!-- 1st part of the sim_view start -->
        <record model="ir.ui.view" id="worker_form">

            <field name="view_mode">tree,form</field>
        </record>



    </data>
</openerp>

这是我的类(class)文件

from openerp.osv import fields, osv
import random

class checkroll(osv.osv):
    _name = "checkroll.plucker"
    _description = "This table is for keeping personal data of plucker"
    _columns = {
        'reg_no': fields.char('Registration Number', size=256, required=True),
        'worker_name': fields.char('Worker Name', size=256, required=True),
        'spouse_name': fields.char('Spouse Name', size=256),
        'gender' : fields.selection((('male', 'Male'), ('female', 'Female'), ('middle', 'Test')), 'Gender', required=True),
        'epf_no':fields.char('EPF Number', size=256)
    }

checkroll()

最佳答案

我后端的数据映射似乎有问题。所以我以管理员身份登录到 openerp 并创建新数据库并将我的模块迁移到那里。 现在它完美地工作

谢谢大家

希望得到这个错误的任何人都能从这个答案中得到帮助
