我有这个功能，可以从 excel 文件中读取和保存域、活动和播放器。当 excel 文件只包含 1 行时，它运行良好，但如果 excel 包含超过 1 个文件，则只保存最后一行，但保存所有行的所有活动，我尝试调试它，我回显每个循环和它读取所有行，我尝试在保存方法之后插入一个回显，以了解它是否成功并且它有效，但是当我在数据库中检查它时，只保存最后一行，但所有活动都保存了。请帮助我，谢谢。
【问题讨论】：
【参考方案1】：用 $this->Activity->clear() 重置模型；
作为 CakePHP 的书 states:
在循环中调用 save 时，不要忘记调用 clear()。
clear 方法在保存数据之前重置模型。如果不使用clear()，则保存行的ID仍在模型中，因此下一次调用save会覆盖之前保存的行。
见CakePHP book on the clear method：
此方法可用于重置模型状态并清除任何未保存的数据和验证错误。
