在laravel 5.2中找不到replicate（）方法

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.

You can use replicate() on a model but not on a collection.

By fetching your records using get() you are returning a collection.

If you are just expecting one record to be returned then replace get() with first() and then replicate() should exist as it will be returning an instance of the model rather than a collection:

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]])->first();

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

You will also need to save() the $newshowtime.
