无法卸载Module - Openerp

标签： python xml module openerp

当我要卸载我自己的module.its时会出错。 （OpenErp ver 7）在我班上我也进入了不同的不同修改。但是我不清楚所有的东西，只保留下面的代码。请帮我找到这个问题.. 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)
  File "/home/priyan/Software/openerp-7.0-20130309-002120/openerp/modules/loading.py", line 416, in load_modules
    pool.get('ir.module.module').module_uninstall(cr, SUPERUSER_ID, mod_ids_to_remove)

  File "/home/priyan/Software/openerp-7.0-20130309-002120/openerp/addons/base/ir/ir_model.py", line 533, in _module_data_uninstall
    WHERE cs.contype=%s and cs.conname=%s and cl.relname=%s""", ('f', name, model_obj._table))
AttributeError: 'NoneType' object has no attribute '_table'

这是我的view.xml文件

<?xml version="1.0"?>

这是我的班级文件

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()

似乎在我的后端数据映射问题。所以我以admin＆amp;登录到openerp。创建新数据库＆amp;将我的模块迁移到那里。 现在它完美无缺

感谢所有

希望任何一个人得到这个错误都会得到这个答案的帮助

检查您是否在 openerp .py中提供了所有必需的依赖项。这解决了我的问题。

答案 2 :(得分：-1)

升级基础模块将删除数据库中的旧引用，并可能有助于卸载模块。

如果仍然无效，您可以自行承担standalone script的风险。做个备份！

编辑 ：链接已更新

EDIT2 ：粘贴 uninstall_module.py ，这样就不会消失。

备份您的数据如果您要使用它。您可以通过传入数据库名称然后传入模块名称来调用脚本。这是一个例子：

chaouche@karabeela ~/CODE/OPENERP/TEST $ python uninstall_module.py test helloworld
No handlers could be found for logger "openerp.modules.graph"
data browse_record(ir.model.constraint, 352)
data.name newfield_country_id_fkey
data browse_record(ir.model.constraint, 353)
data.name newfield_res_partner_category_rel_partner_id_fkey
data browse_record(ir.model.constraint, 354)
data.name newfield_res_partner_category_rel_category_id_fkey
data browse_record(ir.model.constraint, 355)
data.name newfield_title_fkey
data browse_record(ir.model.constraint, 356)
data.name newfield_parent_id_fkey
data browse_record(ir.model.constraint, 357)
data.name newfield_user_id_fkey

data.name newfield_company_id_fkey

data.name newfield_section_id_fkey
data browse_record(ir.model.constraint, 360)
data.name newfield_state_id_fkey

这是 uninstall_module.py ：

    ModuleRemover(args.database,args.module).uninstall()

if __name__ == "__main__":
    main()

对于这个轶事，这就是让我放弃openerp / oodoo以及some other reasons的原因。
