布尔值不能存储在数据库中(laravel)

php artisan make:migration add_is_active_to_users_table --table=users

public function up()
{
    Schema::table('users', function (Blueprint $table) {
        $table->integer('is_active')->default(0);
    });
}

php artisan migrate

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    // ...

    // 定义可访问的字段
    protected $fillable = ['name', 'email', 'is_active'];

    // 定义布尔值访问器
    public function getIsActiveAttribute($value)
    {
        return $value == 1;
    }
}

use App\Models\User;

public function getUser($id)
{
    $user = User::findOrFail($id);

    // 获取布尔值
    $isActive = $user->is_active;

    // 更新布尔值
    $user->is_active = true;
    $user->save();

    // ...
}
