【Laravel】EloquentCollectionにてネスト先カラムをGroupByする

Posted at

はじめに

そもそも1カラムに複数値を持たせるのはどうかという点は置いといておいて、、、。
何らかしらのレスポンスデータをログとしてそのまま格納したい場合などあると思います。
こちら調べてもあまり記事がなく、もしかしたらやりたい人がいるかな~と思いメモとして記事に残しておきます。

要件

Jsonがそのまま入ったカラムにて、Jsonのキーでグルーピングしたい

結論

// ドット「.」でつなげる
$collection->gropuBy('xxx.xxx');

検証内容

テーブル構成

migration.php
Schema::create('conversions', function (Blueprint $table) {
    $table->id();
    $table->json('meta');
    $table->timestamps();
});

データ

id meta created_at updated_at
1 {"gender": "male", "browser": "chrome", "language": "jp"} 2022-05-14 02:56:45 2022-05-14 02:56:45
2 {"gender": "female", "browser": "edge", "language": "en"} 2022-05-14 02:56:45 2022-05-14 02:56:45
3 {"gender": "male", "browser": "safari", "language": "en"} 2022-05-14 02:56:45 2022-05-14 02:56:45

モデル

Convesion.php
<?php

declare(strict_types=1);

namespace App\Models

class Conversion extends BaseModel
{
    protected $fillable = [
        'meta'
    ];

    protected $dates = [
        'updated_at',
        'created_at',
    ];

    protected $casts = [
        'meta' => 'json',
    ];
}

コード

$_conversions = Conversion::get();
$conversions = $_conversions->groupBy('meta.gender');

// 出力結果(ログ抜粋)
Illuminate\Database\Eloquent\Collection Object
    [male] => Illuminate\Database\Eloquent\Collection Object (
        [items:protected] => Array (
            [0] => App\Models\Conversion Object (
                [attributes:protected] =>
                Array ( [id] => 1 [meta] => {"gender": "male", "browser": "chrome", "language": "jp"} [created_at] => 2022-05-14 02:56:45 [updated_at] => 2022-05-14 02:56:45 )
            )
            [1] => App\Models\Conversion Object (
                [attributes:protected] =>
                Array ( [id] => 3 [meta] => {"gender": "male", "browser": "safari", "language": "en"} [created_at] => 2022-05-14 02:58:34 [updated_at] => 2022-05-14 02:58:34 )
            )
        )
    )
    [female] => Illuminate\Database\Eloquent\Collection Object ( [
        [items:protected] => Array (
            [0] => App\Models\Conversion Object (
                [attributes:protected] =>
                Array ( [id] => 2 [meta] => {"gender": "female", "browser": "edge", "language": "en"} [created_at] => 2022-05-14 02:58:09 [updated_at] => 2022-05-14 02:58:09 )
            )
        )
    )

EloquentModelが保持された状態でグループ化される
