如何解决模型相关字段-使用FK更新和创建
我有两个桌子。一个给用户，一个给设备。 我设法从其他表中搜索用户名，但是现在我想创建设备或将设备直接更新为用户名，而不是通过user_for_id。有这样做的可能性吗？将采取哪些步骤？非常感谢您的指导。
第一张表：user_id-主键，用户名，密码；
第二个表：user_equip_id-主键，phone_model，phone_model_series，phone_date_acq，nb_sg_model，nb_sg，_date_acq，display_model，display_series，display_date_acq，user_for_id-表1中指向user_id的外键
