General error: 1215 Cannot add foreign key constraint

[Rhys Williams]

Hi,

Thanks for the great package.

Using Laravel ^8.12, the initial migration fails with an error:
General error: 1215 Cannot add foreign key constraint (SQL: alter table `watch` add constraint `watch_user_id_foreign` foreign key (`user_id`) references `users` (`id`) on delete cascade)

Changing the user_id column in the initial migration from integer to bigInteger allows the migration to run correctly.

$table->bigInteger('user_id')->unsigned()->index();

I hope this helps someone in the future - please let me know if a PR would be useful.

Ah, has the default users.id column been updated to a bigInteger in Laravel 8 by default in the user migration?

Looks like it landed in Laravel 7.

Command	Description
$table->id();	Alias of $table->bigIncrements('id').

from https://laravel.com/docs/7.x/migrations

Default CreateUsersTable migration now looks like:

    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->id();
            // snip
            $table->timestamps();
        });
    }

So I would assume everyone who's tried to install this package with > Laravel 7 has had this issue? lol

Thanks for reporting this.

Please PR it and I will merge it in.

Thanks @rrrhys
