具有消息状态的App Engine消息系统-设计模式
|
我正在构建一个线程化消息系统，该系统将托管在Google AppEngine上
我已经按照Brett Slatkin在“在App Engine上构建可扩展的复杂应用程序”中描述的技术进行了建模
class Message(db.Model):
sender = db.StringProperty()
body = db.TextProperty()
class MessageIndex(db.Model):
receivers = db.StringListProperty()
class Message(model.Model):
sender = model.StringProperty()
body = model.TextProperty()
class _DisplayState(model.Model):
user_key = model.KeyProperty()
state = model.IntegerProperty(default=0) # 0-unread, 1-read, 2-archived
class MessageIndex(model.Model):
receivers = model.StructuredProperty(_DisplayState, repeated=True)
class MessageState(model.Model):
user_key = model.KeyProperty()
message_key = model.KeyPropery()
message_state = model.IntegerProperty(default=0) # 0-unread, 1-read, 2-archived
