在laravel 5.2中找不到replicate（）方法

Question

I am trying to replicate table row and its relationship.

but I am getting error message that replicate() does not exist,

I have seen on stackoverflow that many have used replicate() without any issue, but i am getting this error

my controller code

 public function copyshowtime($cinema_id,$show_date)
{
    $date=new Carbon($show_date);
    $current_show_date=$date->format('Y-m-d');
    $next_show_date=$date->addDay()->format('Y-m-d'); 

    $movieshowtime=Movies_showtimes::with('showdata')->where([['cinema_id','=',$cinema_id],['show_date','=',$current_show_date]])->get();

    $newshowtime=$movieshowtime->replicate();
    return $newshowtime;


}

Is there any namespace i have to use for using replicate() , I am unable to get solution from laravel website also.

help is appreciated.

This code worked perfectly for me

 public function copyshowtime($cinema_id,$show_date)
{
    $date=new Carbon($show_date);
    $current_show_date=$date->format('Y-m-d');
    $next_show_date=$date->addDay()->format('Y-m-d'); 

    $movieshowtime=Movies_showtimes::with('showdata')->where([['cinema_id','=',$cinema_id],['show_date','=',$current_show_date]])->get();

    foreach ($movieshowtime as $item) 
    {
        $item->show_date=$next_show_date;
        $item->show_id=NULL;
        $newshowtime=$item->replicate();
        $newshowtime->push();


        foreach ($item->showdata as $sd) 
        {


            $newshowdata = array(
                                    'showdata_id' => NULL,
                                    'show_id'=>$newshowtime->id,
                                    'category_id'=>$sd->category_id,
                                    'showdata_category'=>$sd->showdata_category,
                                    'showdata_rate'=>$sd->showdata_rate

                                );


           // print_r($newshowdata);
            Movies_showdata::create($newshowdata);



        }
    }

    return redirect()->back();


}

Any suggestions to improve this code will be appreciated.
