我正在尝试做:
MyModel({'text': db.Text('text longer than 500 byets')})
但是得到:
BadValueError: Indexed value fb_education must be at most 500 bytes
我认为这只是旧数据库api对这一问题的影响。

最佳答案
首先动态创建实体:
kindOfEntity = "MyTable"
class DynamicEntity(ndb.Expando):
@classmethod
def _get_kind(cls):
return kindOfEntity
然后在分配文本属性运行时间/动态之后,如下所示
dbObject = DynamicEntity()
key = "studentName"
value = "Vijay Kumbhani"
textProperties = ndb.TextProperty(key)
dbObject._properties[key] = {}
dbObject._values[key] = {}
dbObject._properties[key] = textProperties
dbObject._values[key] = value
dbObject.put()
然后在为关键属性分配文本属性后
