replicate() method not found in laravel 5.2 - php

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.

Answer 1

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.

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.

This type of function would help to clone multiple records and add those records in the same table. I tried a similar code flow and worked.
/**
* Clone multiple records in same table
*
* #params int $cinemaId
* #params string $showDate
*
* #return bool $status
*
* #access public
*/
public function copyShowTime($cinemaId, $showDate)
{
$date = new Carbon($showDate);
$currentShowDate = $date->format('Y-m-d');
// Cloned & Create new records
$moviesShowTimeCollection = Movies_showtimes::with('showdata')->where([['cinema_id','=',$cinemaId],['show_date','=',$currentShowDate]])->get();
// Please check that Model name should change according to camelCases - Movies_showtimes to MoviesShowtimes
if(!$moviesShowTimeCollection->isEmpty()) {
$moviesShowTimeData = $moviesShowTimeCollection->toArray();
foreach ($moviesShowTimeData as $key => $value) {
$primaryKey = 'show_id'; // Needs to check the table primary key name
$primaryId = $value[$primaryKey];
$moviesShowTimeObj = Movies_showtimes::find($primaryId);
// below code can modify while cloaning
//$clonedMoviesShowTimeObj = $moviesShowTimeObj->replicate()->fill([
// 'column_name' => $updatedValue
//]);
$clonedMoviesShowTimeObj = $moviesShowTimeObj->replicate(); // just to clone a single record
$status = $clonedMoviesShowTimeObj->save();
}
}
}
Cheers!

You can easily replicate rows with new changes in that rows
$apcntReplicate = TrademarkApplicantMap::where('trademark_id', $trdIdForPostAssesment)->get();
foreach($apcntReplicate as $oldapnctdata)
{
$apcntreplicated = $oldapnctdata->replicate() ;
//update row data which will newly created by replicate
$apcntreplicated->row_name = $newrowdata;
//save new replicated row
$apcntreplicated->save();
}
Don't use toArray() then each element in the foreach loop will be an Eloquent object.
