迁移laravel 5.5：无法创建除users表和password_reset表之外的表

i have 9 tables, when i run command :

php artisan migrate

only users table, migration table and password_reset table are created in my database. this is my sample code

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateAlatsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('alats', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('merk_id')->unsigned();
            $table->integer('kategori_id')->unsigned();
            $table->integer('operator_id')->unsigned();
            $table->string('nama');
            $table->string('no_plat',15);
            $table->date('tahun');
            $table->string('volume',20);
            $table->text('keterangan');
            $table->enum('status',['ada','disewa','servis']);
            // $table->timestamp('created_at');
            // $table->timestamp('updated_at');
            $table->timestamps();
            $table->foreign('merk_id')->references('id')->on('merks')->onDelete('CASCADE');
            $table->foreign('kategori_id')->references('id')->on('kategoris')->onDelete('CASCADE');
            $table->foreign('operator_id')->references('id')->on('operators')->onDelete('CASCADE');
        });
    }

    public function down()
    {
        Schema::dropIfExists('alats');
    }
}

please help me..?

The migration files need to be migrated in right order. You can't migrate a table with a non existing foreign key.

You probably have a foreign key in some migration and the id key for that will come to existence later in the next migration file. That is why you get this error.

Check your migration files and watch out on order they get created.

For example if you have a foreign key alats_merk_id_foreign then the migration file with alats_merk_id must be migrated before. Hope that this will help you.

Schema::create('alats', function (Blueprint $table) {
    $table->increments('id');
    $table->integer('merk_id')->unsigned();
});

Schema::table('alats', function(Blueprint $table)
{
    $table->foreign('merk_id')
        ->references('merk_id')->on('merk_id_table_name')
        ->onDelete('cascade');
});

First create only table and then create foreign key. And make sure merk_id_table should migrate first.

if you did every thing in all answers

I think your problem is from the foreign/primary key type and length

so you may create the id as integer and its corresponding foreign key as an integer with different length, or even as another type as string forexample

so try to make integers with unsigned and same length

try to use ->unsigned()->length(10)...

solution:

to make the pimary key and its corresponding foreign key in the same exact type and length

Try doing it like this:

        Schema::disableForeignKeyConstraints();

        Schema::create('alats', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('merk_id')->unsigned();
            $table->integer('kategori_id')->unsigned();
            $table->integer('operator_id')->unsigned();
            $table->string('nama');
            $table->string('no_plat',15);
            $table->date('tahun');
            $table->string('volume',20);
            $table->text('keterangan');
            $table->enum('status',['ada','disewa','servis']);
            // $table->timestamp('created_at');
            // $table->timestamp('updated_at');
            $table->timestamps();
            $table->foreign('merk_id')->references('id')->on('merks')->onDelete('CASCADE');
            $table->foreign('kategori_id')->references('id')->on('kategoris')->onDelete('CASCADE');
            $table->foreign('operator_id')->references('id')->on('operators')->onDelete('CASCADE');
        });

        Schema::enableForeignKeyConstraints();

You need to replicate the above for every migration.
