我可以在cakephp3中保存相关记录，但是如果查看代码，则一次保存调用不会同时保存所有记录。 我试图一次性保存所有记录时遇到问题。如果你看看它是如何完成的，你会看到Guardian和Users表是分开保存的。 代码工作并保存记录，但保存所有一次保存调用一直是一个问题，因为我在监护人表上出现错误。
Guardians have a 1 to many relationship with students
Students and Users have a 1 to 1
Students to subjects and availabilityFotStudents both have a many to many
