Laravel Collections除了没有按预期工作

Question

我为特定用户的所有地址列表创建了一个集合,并将其命名为:

$addresses = collect($user->GetAddress);
$addresses = $addresses->where('deleted', 0);
$addresses = $addresses->except(['deleted', 'created_at', 'updated_at']);

我得到的输出如下:

[
        {
            "id": 1,
            "user_id": 1,
            "name": "mr.test",
            "line1": "test1",
            "line2": "test2",
            "pincode": 100,
            "city": "test3",
            "state": "test4",
            "mobile": "test5",
            "default": 0,
            "deleted": 0,
            "created_at": "2017-02-23 09:20:09",
            "updated_at": "2017-02-23 09:20:09"
        }
]

它仍然返回我做的字段,除了.我究竟做错了什么？

我甚至试过这些:

$addresses = $addresses->each(function ($item, $key) {
    return $item->except(['deleted', 'created_at', 'updated_at']);
});

和

$addresses = $addresses->each->except(['deleted', 'created_at', 'updated_at']);

Answer 1

except仅在具有键的单个数组时才有效,而不适用于嵌套数组.使用每个函数的解决方案应该可行,但我认为您必须首先$item转换为集合.

像这样:

$addresses = $addresses->map(function ($item, $key) {
    return collect($item)->except(['deleted', 'created_at', 'updated_at'])->toArray();
});
