我正在管理一个建立在Yii框架上的网站，非常随机地开始得到下面的错误。不确定为什么会发生这种情况，因为源代码还没有被接触。
感谢你的帮助。谢谢！

这是你的线索：
您正指向要素模型中不存在的字段。
它在模型中，在特征表中，你在表单中指向正确的模型了吗？
ycl3bljg2#
我猜您正在尝试访问扩展CActiveRecord的模型的属性。
这意味着：
您已经定义了此属性（移动的_hero_img），但现在已将其删除
或
您通过从表（模型类所关联的表）中删除列（移动的_hero_img）来更改数据库模式。

这看起来像是你的数据库领域的问题。
您是否在表单中添加了新的输入字段“移动的_hero_img”，而没有将该字段添加到数据库中？请提供“feature”表的架构。

对于每个在“属性未定义”问题上挣扎的人，我有一个建议：检查你的模型的
rules()定义和框架的版本，因为Yii（1.1.16）中引入了一个bug，如果属性列表的末尾有额外的空格，就会导致这个错误：这个问题在Yii 1.1.17中得到了解决。
gjmwrych5#
如果在定义属性时设置了字段的（文本）类型，并且在模型中将其定义为布尔值或整数，则也可能会出现“属性n未定义”问题。
例如，下面的文字类型属性是错误的。
正确的定义是
有时候，一个小错误需要几个小时才能被追踪到。

我遇到了同样的问题。Model类中的一切都很完美，但问题仍然存在。重新启动服务器或SQL也无济于事。最后，我清除了protected/runtime/cachexxxx.db文件，然后一切都正常了。我用migrate文件修改了表，有时会出现错误，所以可能是混合了一些东西。
