SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint Laravel

Question

Im trying to create a foreign keys using artisan, but this error show up.

[Illuminate\\Database\\QueryException]                                         


        

Answer 1

Quoting this answer:

To find the specific error run this:

SHOW ENGINE INNODB STATUS;

And look in the LATEST FOREIGN KEY ERROR section.

It may be a problem of type. comment_lot_id must be the exact same type as lot_id. Maybe one is signed and the other unsigned.
