使用唯一的列名称对 Eloquent 集合中的对象进行分组

Question

我有一个典型 users table 的 User 模型，其字段为 id、first_name、last_name、user_name、occupation、password、remember_token、created_at 和 updated_at.

User::all() returns 集合中的所有用户。现在如何列出集合中 occupation 字段下的 user 对象。即我想要这个：

[
    {
        doctor: [
            {
                id: 1,
                firstname: "John",
                lastname: "Dalisay",
                gender: "male",
                email: "john@example.com",
                username: "john123",
                created: "2012-01-15 07:26:14",
                modified: "2012-01-15 07:26:14"
            },
            {
                id: 2,
                firstname: "Jem",
                lastname: "Panlilio",
                gender: "male",
                email: "jemboy09@example.com",
                username: "jem123",
                created: "2012-01-15 07:26:46",
                modified: "2012-01-15 07:26:46"
            }
        ],

        engineer: [
            {
                id: 3,
                firstname: "Jaylord",
                lastname: "Bitamug",
                gender: "male",
                email: "jayjay@example.com",
                username: "jay123",
                created: "2012-01-15 07:27:04",
                modified: "2012-01-15 07:27:04"
            },

                {
                id: 4,
                firstname: "Darwin",
                lastname: "Dalisay",
                gender: "male",
                email: "dada08@example.com",
                username: "dada123",
                created: "2012-01-15 07:25:34",
                modified: "2012-01-15 07:25:34"
            }
        ]
    } ....
]

我试过 groupBy 但没有成功。

Answer 1

数据库聚合无法按照您预期的方式使用所提供的示例。

要获得想要的结果，试试这个：

$users = User::all();
$groupByOccupation = array();
foreach($users as $user) {
   $groupByOccupation[$user->occupation][] = $user;
}

//Now you can return your $groupByOccupation var to view or convertit to JSON

希望这对你有用。
