Change Laravel belongsToMany() returned data format - php

Question

I'm using belongsToMany() in my Laravel model and i need to change the function return format.
public function platform_information(): BelongsToMany
{
return $this->belongsToMany(
PlatformInformation::class,
'platform_information_artist',
'artist_id',
'platform_information_id')->withPivot([
'date', 'value'
]);
}
When I call the function
$artist->platform_information()
->orderBy('platform_information_id', 'asc')
->orderBy('date', 'asc')
->get()
Returns the following data:
[
{
"id": 1,
"platform": "spotify",
"information": "monthly_listeners",
"description": null,
"created_at": null,
"updated_at": null,
"deleted_at": null,
"pivot": {
"artist_id": 1,
"platform_information_id": 1,
"date": "2022-11-09",
"value": 55400500
}
},
{
"id": 1,
"platform": "spotify",
"information": "monthly_listeners",
"description": null,
"created_at": null,
"updated_at": null,
"deleted_at": null,
"pivot": {
"artist_id": 1,
"platform_information_id": 1,
"date": "2022-11-10",
"value": 55395190
}
},
{
"id": 2,
"platform": "spotify",
"information": "followers",
"description": null,
"created_at": null,
"updated_at": null,
"deleted_at": null,
"pivot": {
"artist_id": 1,
"platform_information_id": 2,
"date": "2022-11-09",
"value": 25390584
}
},
{
"id": 2,
"platform": "spotify",
"information": "followers",
"description": null,
"created_at": null,
"updated_at": null,
"deleted_at": null,
"pivot": {
"artist_id": 1,
"platform_information_id": 2,
"date": "2022-11-10",
"value": 25410584
}
}
]
The data obtained are correct, but not in the format in which I need them.
This is the format that i need:
[
{
"id": 1,
"platform": "spotify",
"information": "monthly_listeners",
"data" : [
{
"artist_id": 1,
"platform_information_id": 1,
"date": "2022-11-09",
"value": 55400500
},
{
"artist_id": 1,
"platform_information_id": 1,
"date": "2022-11-10",
"value": 55395190
}
]
},
{
"id": 2,
"platform": "spotify",
"information": "followers",
"data" : [
{
"artist_id": 1,
"platform_information_id": 2,
"date": "2022-11-09",
"value": 25390584
},
{
"artist_id": 1,
"platform_information_id": 2,
"date": "2022-11-10",
"value": 25410584
}
]
}
]
Is there any way to do this using the belongsToMany() function directly?
Or do I have to do it manually in the controller?

Answer 1

I had not tested it but what I have get from the question, it should work.
I am assuming that you have a model Artist in your Models directory.
$artist = \App\Models\Artist::with('platform_information')->get();
Then you can dd() to verify the format
dd($artist->toArray());
