编辑:这是我的整个模型。我没有为几个部署更改它:

编辑 2:通过更改变量 PAGESIZE，我可以为最新的实体加载页面。我没有找到错误开始/结束的位置:def get(self, cursor=None, limit=60, PAGESIZE = 1): 有效，我现在尝试使用更大的 PAGESIZE 即 def get(self, cursor=None, limit=60, PAGESIZE = 10):

这是 App Engine 数据存储区的一个已知问题。它与您的代码或应用无关。

App Engine 团队正在努力修复，在您等待期间，此处发布了一个解决方法:http://groups.google.com/forum/#!topic/google-appengine-python/ClkOIalYD3s
