我有一個以下身份驗證表：<?phpuse Illuminate\Database\Migrations\Migration;use Illuminate\Database\Schema\Blueprint;use Illuminate\Support\Facades\DB;use Illuminate\Support\Facades\Schema;class CreateAuthTable extends Migration{ /** * Run the migrations. * * @return void */ public function up() { Schema::create('auth', function (Blueprint $table) { $table->uuid('id')->primary(); $table->string('email', 255)->index()->unique(); $table->string('password', 96); $table->timestamps(); }); DB::statement('ALTER TABLE auth ALTER COLUMN id SET DEFAULT uuid_generate_v4();'); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::dropIfExists('auth'); }}這是模型：<?phpnamespace App\Models;use Illuminate\Database\Eloquent\Model;use Illuminate\Foundation\Auth\User as Authenticable;use Illuminate\Support\Facades\Hash;use Laravel\Passport\HasApiTokens;class User extends Authenticable{ use HasApiTokens; protected $table = "auth"; protected $fillable = ["email", "password"]; public $incrementing = false; protected $keyType = 'string'; protected $casts = [ 'id' => 'string' ]; private $hashOptions = [ 'memory' => 1024, 'time' => 2, 'threads' => 1 ]; public function setPasswordAttribute($value) { $this->attributes['password'] = Hash::make($value, $this->hashOptions); }}

只需確保強制轉換為字符串且主鍵名稱正確
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
protected $casts = [
'id' => 'string'
];
protected $primaryKey = "id";
}
如果你將 $incrementing 設置為 false，它會破壞它并始終返回 false，因為它告訴代碼該 id 不是自動生成的，因此永遠不會被獲取。
class User extends Model
{
public $incrementing = false;
// ...
}
$user = new User;
$user->save();
dd($user->id);
// null
還要確保在遷移中啟用 uuid 擴展
<?php
class AddUuidExtensionToPostgre extends Migration
{
public function up()
{
DB::statement('CREATE EXTENSION IF NOT EXISTS "uuid-ossp";');
}
public function down()
{
DB::statement('DROP EXTENSION IF EXISTS "uuid-ossp";');
}
}
這是一個例子
Schema::create('users', function (Blueprint $table) {
$table->uuid('id');
$table->primary('id');
// ...
});
DB::statement('ALTER TABLE users ALTER COLUMN id SET DEFAULT uuid_generate_v4();');
