Laravel 6.0, MySQL8.0 にて、SQLSTATE[HY000]: General error: 1822 Failed to add the foreign key constraint

Posted at 
PDOException::("SQLSTATE[HY000]: General error: 1822 Failed to add the foreign key constraint. Missing index for constraint 'advisors_user_id_foreign' in the referenced table 'users'")

Laravelでマイグレーション時に外部キーをセットしようとしたが、idがPKじゃ無くなっていたことにより上記エラーが出た

$table->primary('id')を加えてあげることで解決
