Openerp odoo的外形视图工作不正常

我创建了一个名为student的模块。我有两个表单视图。第一个表单只包含一个重定向到第二个表单的按钮。第二个表单由几个字段组成，如名字、姓氏、出生日期、地址、电话和电子邮件。当我在第一个表单中并且想要重定向到第二个表单时，它会给我一个称为“完整性错误”的错误，这意味着它正在检查非空约束，因为我已经在第二个表单中将first_name和last_name字段设为必填字段。为什么当我在第一个表单中时它会检查第二个表单字段。但如果我将这两个字段设置为非强制性，那么一切都会正常工作。所以我的重定向代码没有问题。我不想删除这两个字段上的必需属性。我已经附上了图片和我的代码也

即使从.py文件中删除了

required=True

，如果您检查表属性，我也不会更改

解决方案：删除

required=True

后，只需从设置中已安装的模块升级该特定模块。然后，只有您所做的更改才会反映在db中，并且它可以正常工作。

在本模块中，如果我删除必需的属性，一切都可以正常工作，但在更大的模块中，如销售管理，帐户和财务管理如果我在python代码中删除所有这些字段的必需属性，我会得到一个名为AttributeError的错误：“NoneType”对象没有属性“fields\u view\u get”，是的，但您必须通过继承操作该属性，不是吗？否则，这是一个糟糕的做法，因为一旦您更新了Odoo，您将丢失更改。
