How to clone data that has self relational/ self reference in laravel - laravel

Question

How to replicate/clone all data in a table that has self-relation in Laravel?
I have this table:
members table
id
member_id
company_id
name
1
null
23
John
2
1
23
James
3
1
23
Ken
4
null
23

EXISTING CODE
And I want to replicate all data that has company_id of 23 using
$members = Members::where['company_id' => 23]->get();
foreach ($members as $member) {
$duplicate = $member->replicate()->fill(['company_id' => 24);
$duplicate->save();
}
Results of the code
members table
id
member_id
company_id
name
1
null
23
John

23
James

But in that code, the replication of self-relation is wrong. How can I do it?
Expected result
members table
id
member_id
company_id
name
1
null
23
John

I'm sorry if my English is messed up, but I hope you get the idea of what I'm trying to do. Thank you!

Answer 1

Try this .You have two options to replicate
$members = Members::where(['company_id' => 23])->get();
foreach ($members as $member) {
$duplicate = $member->replicate();
$duplicate->company_id=24;
$duplicate->save();
}
});
or
$members = Members::where(['company_id' => 23])->get();
foreach ($members as $member) {
$duplicate = $member->replicate()->fill(['company_id'=>24]);
$duplicate->save();
}
});
Updated
$members = Members::where(['company_id' => 23])->get();
$tempIdMap=[];
foreach ($members as $key=>$member) {
if($key==0){
$tempIdMap[$member->id]=$member->member_id;
}
$duplicate = $member->replicate()->fill(['company_id'=>24,'member_id'=>isset( $tempIdMap[$member->member_id])? $tempIdMap[$member->member_id]:null]);
$duplicate->save();
$tempIdMap[$member->id]=$duplicate->id;
}
