  <pre><code>   public function update(
        BoxItemUpdateRequest $request,
        ModelA $modelA ,
        ModelB $modelB ,
        ModelC $modelC
     ) {
        $modelA-&gt;decrement(
           'total', 
            $request-&gt;quantity1- $request-&gt;quantity2
        );
        $modelA-&gt;timestamps = true;
        $modelA-&gt;touch();
        $modelA-&gt;save();
        $modelB-&gt;decrement(
          'total',
          $request-&gt;quantity1- $request-&gt;quantity2
        );
        $modelB-&gt;timestamps = true;
        $modelB-&gt;touch();
        $modelB-&gt;save();
        $modelC-&gt;quantity_accepted = $request-&gt;quantity2;
        $modelC-&gt;timestamps = false;
        $modelC-&gt;touch();
        $modelC-&gt;save();
  
        return Response::json([
          'status' =&gt; HttpStatusCode::HTTP_OK,
        ]);
