我能够在cakephp3中保存关联的记录，但是如果您查看代码，则记录不会一次全部保存，并带有1次保存呼叫。 我尝试一次保存所有记录时遇到了问题。如果你看看它是如何完成的，你会看到Guardian和Users表单独保存。 代码工作并保存记录，但一次保存1保存调用一直是一个问题，因为我在监护人表上发生错误。立即保存所有关联的记录
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

我仍然不能得到这个工作，所以如果有人有一个想法？ – ajt
