Python 无法卸载模块-Openerp

当我要卸载自己的模块时，它会给出一个错误。（开场白7）在我的课堂上，我也输入了不同的修改。但我没有清除所有内容，只保留下面的代码。请帮我找出问题所在。。 现在，当我尝试安装通讯录模块时，也出现了这个错误

  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

    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

我的后端中的数据映射似乎有问题。因此我以管理员身份登录到openerp，创建新数据库并将模块迁移到那里。 现在它可以完美地工作了

谢谢大家

希望任何出现此错误的人都能从这个答案中获得帮助

检查您是否在openerp.py中提供了所有必要的依赖项。这为我解决了问题。

升级基本模块将删除数据库中的旧引用，并可能有助于卸载您的模块

如果这仍然不起作用，你可以自己冒险尝试。备份

编辑：链接已更新

EDIT2：在此处粘贴卸载\u module.py，使其不会消失

如果要使用此功能，请备份数据。通过传入数据库名称然后传入模块名称来调用脚本。下面是一个例子：

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 browse_record(ir.model.constraint, 358)
data.name newfield_company_id_fkey
data browse_record(ir.model.constraint, 359)
data.name newfield_section_id_fkey
data browse_record(ir.model.constraint, 360)
data.name newfield_state_id_fkey
chaouche@karabeela ~/CODE/OPENERP/TEST $

下面是卸载模块.py：

对于这个轶事，这就是为什么我放弃了openerp/oodoo，以及。

您创建了一个模型，但在创建过程中更改了它的名称，而openerp似乎不知道如何处理这个问题。我不知道如何解决这个问题，我也处于同样的情况。当然，你可以从一个新的数据库开始，在那里导入模块，但这是一个解决办法。链接万岁！感谢@Odedra，刚刚更新了该页面存档版本的链接。
