错误提示:
sqlalchemy.exc.noforeignkeyserror: could not determine join condition between parent/child tables on relationship wife.wife - there are no foreign keys linking these tables. ensure that referencing columns are associated with a foreignkey or foreignkeyconstraint, or specify a 'primaryjoin' expression.
分析过程:
我看懂了报错原因,按照网上的解决方法都试了一遍,都没有效果,人都要炸了,
最后发现:我把代码写错地方了,放错了类,本来是给一个teacher类的设置外键,但是直接加到了wife的下面,所以一遍又一遍地检查了语法,大小写,类名,始终没有发现问题所在。
之后查错,除了看看语句本身有没有错,再看看位置写没写错吧!
