Using polymorphic relation how to save array data? - php

Question

I want to save array of data using polymorphic relation one to many.
I have the following Models.
schedule task model
class ScheduleTask extends Model
{
protected $guarded = [];
public function taskable()
{
return $this->morph To(__FUNCTION__, 'taskable_type', 'taskable_id');
}
}
prelimstest model
class PrelimsTest extends Model
{
public function tasks()
{
return $this->morph Many(Schedule Task::class, 'taskable');
}
}
maintest model
class MainsTest extends Model
{
public function tasks()
{
return $this->morphMany(ScheduleTask::class, 'taskable');
}
}
video model
class Video extends Model
{
public function tasks()
{
return $this->morphMany(ScheduleTask::class, 'taskable');
}
}
And my controller
class ScheduleController extends Controller
{
public function store(Request $request)
{
$data = array();
foreach ($prelims_id as $key => $value) {
$data[] = [
'course_id' => $prelims_course_id[$key],
'status' => 'incomplete',
'schedule_id' => 1
];
$prelims_save = PrelimsTest::find($value);
}
$prelims_save->tasks()->createMany($data);
$data2 = array();
foreach ($mains_id as $key2 => $value2) {
$data2[] = [
'course_id' => $mains_course_id[$key2],
'status' => 'incomplete',
'schedule_id' => 1
];
$mains_save = MainsTest::find($value2);
}
$mains_save->tasks()->createMany($data2);
$data3 = array();
foreach ($videos_id as $key3 => $value3) {
$data3[] = [
'course_id' => $videos_course_id[$key3],
'status' => 'incomplete',
'schedule_id' => 1
];
$videos_save = Video::find($value3);
}
$videos_save->tasks()->createMany($data3);
}
}
My problem is while i'm saving taskable_id enters last value of array.
Does anyone know how to solve this part, that I can save the polymorphic relation?
Thanks in advance.
