我目前在后端使用 Doctrine 1.2.2 和 MySQL。当我尝试使用记录或延迟加载水合模式检索多个项目的结果集时，只显示一个项目。但是，当我使用阵列水合模式时，我看到了所有结果。始终如一地，只检索结果集中的最后一项。

我误解了 API 吗？模型是否定义不正确（它是自动生成的）。不应该这么简单吗？

现在，我正在启动我的调试器，我将逐步浏览 Doctrine 的源代码。

// Model used:

感谢#doctrine irc 频道上的好人，我现在可以正常工作了。

问题的根源是我没有在投票表的主键上设置自动增量。因此，如果您遇到类似问题，请确保您选择作为模型中主键的任何列也具有在数据库模式中设置的自动增量位。
