Question

我有一个带有softdeletes的模型，如果我添加一个追加字段，我的sofdeletes实现不起作用，有人知道发生了什么吗？

use Illuminate\Database\Eloquent\Model;

use Illuminate\Database\Eloquent\SoftDeletes;

class Users extends Model
{
    use SoftDeletes;

    protected $dates = ['deleted_at'];

    protected $table = 'users';

    protected $appends = ['assigned'];

    protected $fillable = ['category_id'];

    public function __construct()
    {
        $this->assigned = false;
    }

    public function setAssignedAttribute($value)
    {
        $this->attributes['assigned'] = $value;
    }

    public function getAssignedAttribute($value)
    {
        return $value;
    }
}

Answer 1

这不是你的追加领域。你的构造函数没有调用父构造函数，这是启动你的软删除特征的东西。在构造函数中添加parent::__construct()。它应该匹配父母的签名，所以它应该是：

public function __construct(array $attributes = [])
{
    $this->assigned = false;

    parent::__construct($attributes);
}

您误读了文档，您的访问者没有正确的名称：

use Illuminate\Database\Eloquent\Model;

use Illuminate\Database\Eloquent\SoftDeletes;

class Users extends Model
{
    use SoftDeletes;

    protected $dates = ['deleted_at'];

    protected $table = 'users';

    protected $appends = ['assigned'];

    protected $fillable = ['category_id'];

    public function __construct()
    {
        $this->assigned = false;
    }

    public function setIsAssignedAttribute($value)
    {
        $this->attributes['assigned'] = $value;
    }

    public function getIsAssignedAttribute($value)
    {
        return $value;
    }
}

您需要Is，即使它不是变量名称的一部分。
