python - Change db.ComputedProperty from StringProperty to TextProperty

Question

I am kind of new to GAE and I was trying to use @db.ComputedProperty to dynamically add field values However I am getting the error message

Property xxxx is 721 bytes long; it must be 500 or less. Consider Text instead, which can store strings of any length.

It seems that @db.ComputedProperty defaults to StringProperty Is there any way to change it to TextProperty?

让您的计算属性返回一个实例db.Text而不是字符串。但是，正如 Wooble 指出的那样，这样做绝对没有意义：计算属性的存在是为了帮助建立索引，如果您不为数据编制索引，您还不如使用常规属性而不将其存储在数据存储中.
