Masalah migration pada laravel
Halo! Saya ingin bertanya kenapa setiap saya mengikuti tutorial pada saat migrate selalu muncul error seperti ini? Saya menggunakan laravel 5.8 Error :
Illuminate\Database\QueryException : SQLSTATE[HY000]: General error: 1005 Can't create table `laravel_relation`.`#sql-1200_1e` (errno: 150 "Foreign key constraint is incorrectly formed") (SQL: alter table `passports` add constraint `passports_user_id_foreign` foreign key (`user_id`) references `users` (`id`) on delete cascade)
at C:\xampp\htdocs\blog\vendor\laravel\framework\src\Illuminate\Database\Connection.php:664
660| // If an exception occurs when attempting to run a query, we'll format the error
661| // message to include the bindings with SQL, which will make this exception a
662| // lot more helpful to the developer instead of just
the database's errors.
663| catch (Exception $e) {
> 664| throw new QueryException(
665| $query, $this->prepareBindings($bindings), $e
666| );

Kode:
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreatePassportsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('passports', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('no_pass', 100);
$table->integer('user_id')->unsigned();
$table->timestamps();
$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('passports');
}
}
2 Jawaban:
biasanya tabel dari primary keynya ('users') belum ke migrate,coba bikin schema::table dibawah schema::create.bentuknya kurang lebih jadi gini
public function up() { Schema::create('passports', function (Blueprint $table) { $table->bigIncrements('id'); $table->string('no_pass', 100); $table->integer('user_id')->unsigned(); $table->timestamps();
});
Schema:table('passports',function(Blueprint $table){
$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
});
}

Saya sudah ikuti cara ini, lalu saya migrate:fresh errornya masih sama
Jawaban Terpilih
Coba perhatikan pada file migrate user, cari baris berikut <pre> $table->increments('id'); //atau $table->bigIncrements('id'); </pre> kalau menggunakan increments biasa, kode di atas pada bagian <pre> $table->integer('user_id')->unsigned(); // Sudah cocok </pre> tetapi kalau menggunakan bigIncrements, coba diubah menjadi <pre> $table->bigInteger('user_id')->unsigned(); // atau bisa juga $table->unsignedBigInteger('user_id'); </pre> Semoga bisa membantu.
