Laravel Migration Compatibility

Laravel 5.8 And The BigInt Problem

As of Laravel 5.8, migration stubs use the bigIncrements method on ID columns by default. Previously, ID columns were created using the increments method.

Foreign key columns must be of the same type. Therefore, a column created using the increments method can not reference a column created using the bigIncrements method.

This small change is a big source of problems for packages that define references to the default Laravel user table.

This package helps to solve this problem by extending Laravel's Blueprint class by a method that can detect the actual referenced field type:

class CreateProfilesTable extends Migration
{
    public function up()
    {
        Schema::create('profiles', function (Blueprint $table) {
            $table->increments('id');

            // Make `user_id` field the same type as the `id` field of the `user` table:
            $table->intOrBigIntBasedOnRelated('user_id', Schema::connection(null), 'users.id');

            //...

            $table->foreign('user_id')
                ->references('id')
                ->on('users');
        });
    }
//...
