我在AppEngine中有下一个模型:
class Category(db.Model):
name = db.StringProperty()
description = db.StringProperty()
class Blog(db.Model, Handler) :
subject = db.StringProperty(required = True)
content = db.TextProperty(required = True)
date = db.DateProperty(auto_now_add = True)
last_modified = db.DateProperty(auto_now = True)
category = db.ReferenceProperty(Category, required=True)
这是一种正确的方法是否规范化我的数据?
