生成棉花糖架构

frommarshmallow_pynamodbimportModelSchemaclassUserSchema(ModelSchema):classMeta:model=Useruser_schema=UserSchema()

（反）序列化数据

user=User(last_name="Smith",first_name="John")user_schema.dump(user).data# {u'first_name': u'John', u'last_name': u'Smith', u'email': None}user_schema.load({"last_name":"Smith","first_name":"John"}).data# user<Smith>

嵌套模型？没问题
