在抽象类的Update方法中使用foreach循环将键值填充到模型中 - Laravel mass assignment to model in Update method in abstract class using foreach loops to fill keys with values

Laravel mass assignment to model in Update method in abstract class using foreach loops to fill keys with values

如何创建属于抽象类的update()函数的泛型方法?确切地说，我希望它能够动态地生成数组$keys并与更新的$values链接，以便不同的存储库可以从这个抽象类中使用这个函数。

public function update($id, array $data)
{
    $related              = $this->modelClassInstance->find($id);
    $related->name        = $data['name'];
    $related->description = $data['description'];
    $related->started_at  = $data['started_at'];
    $related->ended_at    = $data['ended_at'];
    if($related->save()) {
      $response = MyResponse::error(201, true, 'Event sucessfully updated');
      return $response;
    } 
    else {
      $response = MyResponse::error(200, false, 'Event unsucessfully updated');
      return $response;
    }
}

我需要这样的东西

$data = array(1,2,3,4,5,6,7,8,9);
foreach($data as $key=>$value)
{
   .....
}

我的键是名称、描述、started_at和endd_at，但这意味着该函数是特定于模型的。我希望这个键是动态生成的，并从传递的数据中获得新的值。

for循环对于Laravel方法来说是不必要的，在进行了各种站点的研究之后，这些方法是相当可靠的。我想到了这个简单的解决办法

    public function update($id, array $data)
            {
                $related = $this->modelClassInstance->find($id);
                $related->fill($data);
                if($related->save()) 
                {
                    $response = MyResponse::error(201, true, 'Event sucessfully updated');
                    return $response;
                } 
                else 
                {
                    $response = MyResponse::error(200, false, 'Event unsucessfully updated');
                    return $response;
                }
            }

这是fill()方法在Laravel Eloquent Model中的实现方式，如果你想寻找类似的实现方法，请参考

public function fill(array $attributes)
    {
        $totallyGuarded = $this->totallyGuarded();
        foreach ($this->fillableFromArray($attributes) as $key => $value)
        {
            $key = $this->removeTableFromKey($key);
            // The developers may choose to place some attributes in the "fillable"
            // array, which means only those attributes may be set through mass
            // assignment to the model, and all others will just be ignored.
            if ($this->isFillable($key))
            {
                $this->setAttribute($key, $value);
            }
            elseif ($totallyGuarded)
            {
                throw new MassAssignmentException($key);
            }
        }
        return $this;
    }
