Laravel雄辯的多維數組質量分配

Question

我正在創建一個Restful應用程序，因此我收到了一個看起來像這樣的POST請求

$_POST = array (
'person' => array (
    'id' => '1',
    'name' => 'John Smith',
    'age' => '45',
    'city' => array (
        'id' => '45',
        'name' => 'London',
        'country' => 'England',
    ),
),

）;

我想保存我的人模型並設置其city_id 。

我知道最簡單的方法是使用$ person-> city_id = $ request ['city'] ['id];手動進行設置。 但是這種方式並沒有幫助我....這段代碼只是一個例子，在我的真實代碼中，我的模型有15個關系

有沒有什么辦法可以像$ person-> fill（$ request）這樣呢？ ？

我的模型如下：

市

class City extends Model {

    public $timestamps = false;
    public $guarded= ['id'];//Used in order to prevent filling from mass assignment

    public function people(){
        return $this->hasMany('App\Models\Person', 'city_id');
    }

}

人

class Person extends Model {

public $timestamps = false;
public $guarded= ['id'];//Used in order to prevent filling from mass assignment

public function city(){
    return $this->belongsTo('App\Models\City', 'city_id');
}
public static function savePerson($request){//Im sending a Request::all() from parameter
    $person = isset($request['id']) ? self::find($request['id']) : new self();
    $person->fill($request);//This won't work since my $request array is multi dimentional
    $person->save();
    return $person;
}

}

這有點棘手，但是您可以在模型中覆蓋fill方法，並設置deeplyNestedAttributes()來存儲將在請求中查找的屬性

class Person extends Model {

    public $timestamps = false;
    public $guarded= ['id'];//Used in order to prevent filling from mass assignment

    public function city(){
        return $this->belongsTo('App\Models\City', 'city_id');
    }

    public static function savePerson($request){//Im sending a Request::all() from parameter
        $person = isset($request['id']) ? self::find($request['id']) : new self();
        $person->fill($request);//This won't work since my $request array is multi dimentional
        $person->save();
        return $person;
    }

    public function deeplyNestedAttributes()
    {
        return [
            'city_id',
            // another attributes
        ];
    }

    public function fill(array $attributes = [])
    {
        $attrs = $attributes;
        $nestedAttrs = $this->deeplyNestedAttributes();

        foreach ($nestedAttrs as $attr) {
            list($relationName, $relationAttr) = explode('_', $attr);

            if ( array_key_exists($relationName, $attributes) ) {

                if ( array_key_exists($relationAttr, $attributes[$relationName]) ) {

                    $attrs[$attr] = $attributes[$relationName][$relationAttr];
                }
            }
        }
        return parent::fill($attrs);
    }

}
