PHP-一般错误：1364栏位’identifier’没有预设值

Schema::create('users', function (Blueprint $table) {
    $table->increments('id');
    $table->integer('identifier')->unique();
    $table->string('username')->unique();
    $table->string('name');
    $table->string('avatar');
    $table->string('Trade')->nullable();
    $table->decimal('funds')->default(0);
    $table->enum('visibility', [1, 2, 3]);
    $table->uuid('api_token');
    $table->timestamps();
});

和

User::updateOrCreate([
    'identifier' => 'dasdasd',
    'username' => $user->nickname,
    'name' => $user->name,
    'avatar' => $user->avatar,
    'visibility' => $user->visibility,
    'api_token' => Uuid::generate()
]);

结果：sqlSTATE [HY000]：常规错误：1364字段’identifier’没有默认值(sql：插入用户(名称,Updated_at,created_at)值(Guilhermearaújo,2017-03-26 20:39:04 ,2017-03-26 20:39:04))

怎么了？

解决方法:

您应该为标识符字段生成一个唯一的整数：

'identifier' => 12345,

由于使用的是updateOrCreate(),因此应将标识符添加到$fillable数组中：

protected $fillable = ['identifier', ....];
