Mapping data in Laravel - php

Question

I am not able to understand the response for API in Laravel, it is confusing.
I expect this output
{
"month": "January",
"year": 2020,
"history_data": [
{
"id": 27,
"jurnal_id": 12313,
"name": "Transaksi RAHN FLEKSI",
"point": 500,
"status": "SUKSES",
"created_at": "2020-03-18 17:03:26",
"updated_at": "2020-03-18 17:03:26",
},
]
},
{
"month": "February",
"year": 2020,
"history_data": [
{
"id": 27,
"jurnal_id": 1231313,
"name": "Transaksi RAHN FLEKSI",
"point": 500,
"status": "SUKSES",
"created_at": "2020-03-18 17:03:26",
"updated_at": "2020-03-18 17:03:26",
}
],
{
"month": "February",
"year": 2021,
"history_data": [
{
"id": 182,
"jurnal_id": 13213,
"name": "Transaksi RAHN FLEKSI",
"point": 500,
"status": "SUKSES",
"created_at": "2021-02-18 17:03:26",
"updated_at": "2021-02-18 17:03:26",
},
{
"id": 1812313,
"jurnal_id": 12313313,
"name": "Transaksi RAHN FLEKSI",
"point": 500,
"status": "SUKSES",
"created_at": "2021-02-18 17:03:26",
"updated_at": "2021-02-18 17:03:26",
}
]
{
"month": "March",
"year": 2021,
"history_data": [
{
"id": 183,
"jurnal_id": 132313,
"name": "Transaksi RAHN FLEKSI",
"point": 500,
"status": "SUKSES",
"created_at": "2021-03-18 17:03:26",
"updated_at": "2021-03-18 17:03:26",
}
]
}
The 'history_data' is Grouped by year and month if I'm not wrong.
But, I still get response like below
"2021": [
{
"month": "February",
"year": "2021",
"history_data": {
"id": 2,
"id_jurnal": 1846756745650,
"name": "Transaksi ARRUM SAFAR",
"point": 1200,
"status": "SUKSES",
"created_at": "2021-02-13 10:11:21",
"updated_at": "2020-02-13 10:11:21",
"cif_number": "1003002713"
}
},
{
"month": "March",
"year": "2021",
"history_data": {
"id": 29,
"id_jurnal": 1015205749121113,
"name": "Transaksi RAHN FLEKSI",
"point": 500,
"status": "SUKSES",
"created_at": "2021-03-18 17:26:57",
"updated_at": "2020-03-18 17:26:57",
"cif_number": "1015205749"
}
}
],
"2020": [
{
"month": "February",
"year": "2020",
"history_data": {
"id": 1,
"id_jurnal": 1846756745652,
"name": "Transaksi ARRUM SAFAR",
"point": 1200,
"status": "SUKSES",
"created_at": "2020-02-13 09:52:56",
"updated_at": "2020-02-13 09:52:56",
"cif_number": "1003002713"
}
},
]
Here's the PHP / Laravel code
$historyPoints = $this->historyPoint
->select(
DB::raw("REGEXP_REPLACE(to_char(created_at, 'Month'), '\s+$', '') as month"),
DB::raw("date_part('Year', created_at) as year")
)
->groupBy('year', 'month')
->orderBy('year', 'desc')
->get();
$arr = [];
foreach($historyPoints as $historyPoint) {
foreach(HistoryPointAdd::all() as $data) {
$month = date('F', strtotime($data->created_at));
$year = date('Y', strtotime($data->created_at));
if($month == $historyPoint->month && $year == $historyPoint->year) {
$arr[] = [
'month' => $historyPoint->month,
'year' => $historyPoint->year,
'history_data' => $data
];
}
}
}
$makeToCollection = collect($arr)->groupBy('year');
return $this->sendSuccess($this->successMessage, $makeToCollection);
I'm using PostgreSQL for the database.
Thank you very much

The problem is :
$makeToCollection = collect($arr)->groupBy('year');
The groupBy method groups the collection's items by a given key
Just use :
$makeToCollection = collect($arr);
Btw, collection allows you to chain its methods to perform fluent mapping and reducing :
$historyPoints = $this->historyPoint
->select(
DB::raw("REGEXP_REPLACE(to_char(created_at, 'Month'), '\s+$', '') as month"),
DB::raw("date_part('Year', created_at) as year")
)
->groupBy('year', 'month')
->orderBy('year', 'desc')
->get();
/***** Here we go *****/
$makeToCollection = $historyPoints->map(function ($item) {
$history_data = [];
foreach (HistoryPointAdd::all() as $data) {
$month = date('F', strtotime($data->created_at));
$year = date('Y', strtotime($data->created_at));
if ($month == $historyPoint->month && $year == $historyPoint->year) {
$history_data[] = $data;
}
}
$item['history_data'] = $history_data;
return $item;
});
return $this->sendSuccess($this->successMessage, $makeToCollection);
