General error: 1215 Cannot add foreign key constraint laravel
Laravel 5.8 Added bigIncrements As Defaults
So there is mismatch in foreign key field types. You see bigIncrements(id) in
User table and unsigned Integer(user_id) in questions table.
How to fix:
1. Either change original migration from bigIncrements() to just
increments()
2. Or in your foreign key column do unsignedBigInteger() instead of
unsignedInteger().error code 1215 cannot add foreign key constraint
Try this if are data in one or more tables from foreign key references
set foreign_key_checks=0;
Else it is a problem in forign key parameters (references parameters)Copyright © 2021 Codeinu
