AttributeError：“ NoneType”对象在Openerp中没有属性“ fields_get”

Question

为什么会发生此错误？ 任何人都熟悉此错误。 当我单击任何选项卡时，例如：销售，购买，人力资源，会计等，我收到此错误。

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

Answer 1

看起来像是问题所在：

self.pool.get(act.res_model)

它应该是您使用_name属性的名称

试试看

self.pool.get(act.res.model)

Answer 2

self.pool.get(act.res_model)返回None （因为词典pool没有键为act.res_model的条目）。

因此，对该对象的.fields_get(...)调用失败（因为None显然没有这样的方法，这是错误消息试图告诉您的方法）。
