Laravel雄辩创建空字段 [英] Laravel Eloquent create null field

问题描述

class Product extends Model
{
    use SoftDeletes;
    protected $dates = ['deleted_at'];
    public $timestamps = true;
    protected $fillable = ['name'];
    protected $connection = 'pos';

    public function __construct()
    {
        config(['database.connections.pos.database' => 'pos_1']);
        parent::__construct();
    }
}

Product::create(['name' => 'Snack']);

< 30:24'，updated_at ='2016-06-26 18:30:24'，deleted_at = null

on my db id=1, name=null, created_at='2016-06-26 18:30:24', updated_at='2016-06-26 18:30:24', deleted_at=null

为什么name = null？

Why name=null?

更新帖子

当我使用

$p = new Product();
$p->name = 'Snack';
$p->save();

但为什么 Product :: create（['name'=>小费']）; 填充为空？

我在该构造函数中缺少pass数组作为参数。

ah I missing pass array as parameter on that constructor.

        public function __construct(array $attributes)
        {
            config(['database.connections.pos.database' => 'pos_1']);
            parent::__construct($attributes);
        }

推荐答案

可能原因是你再次不要运行父构造函数。

Probably the reason is that you again don't run parent constructor.

而不是：

public function __construct()
{
    config(['database.connections.pos.database' => 'pos_1']);
}

您应该使用：

public function __construct()
{
    config(['database.connections.pos.database' => 'pos_1']);
    parent::__construct();
}

请注意，对于您的雄辩模型，您还有连接属性，所以你可以设置数据库连接的名称。

Be aware that for your Eloquent Model you have also connection property, so you could probably set also name of database connection.
