Laravel 5.3は、私はプロパティのモデルを持っていると私は、次の範囲作った派生フィールド

Question

でモデルをページ分割することはできません。

$properties = Property::search($search) 
     ->addSelect('properties.*') 
     ->paginate($this->per_page); 

：私はそのようにのようないくつかのページ分割の結果を試してみて、取得した場合

public function scopeSearch($query, $search) 
{ 
    return $this->addSelect(DB::raw("(3959 * acos(cos(radians(".$search['latitude'].")) * cos(radians(properties.latitude)) 
         * cos(radians(properties.longitude) - radians(".$search['longitude'].")) + sin(radians(".$search['latitude'].")) 
         * sin(radians(properties.latitude)))) AS distance")) 
     ->having('distance', '<=', $search['radius']); 
} 

を

私は次のエラーを取得する：改ページは、Aを実行しませんカウントクエリをやっているよう

QueryException in Connection.php line 729: 
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'distance' in 'having clause' (SQL: select count(*) as aggregate from `properties` where `properties`.`deleted_at` is null having `distance` <= 25) 

が見えますフィールド距離が存在しないようにddSelect（）メソッドを使用します。選択肢を追加する方法はありますか？

のフルスタックトレース：あなたはhaving部分にdistance列の定義全体をコピーして何ができるか

Answer 1

。実際には、これを達成するためにhavingRaw関数を使用する必要があります。

addSelectとhavingRawは両方ともバインドを使用する必要があります。これは、コードがSQLインジェクションに対して脆弱であるためです。
