laravel - Laravel 引用母亲查询

Question

我有这个雄辩的疑问：

$result = Model::whereBetween('created_at', [$date_from, $date_to]);

$active_records = $result->where('status_id', 1)->get();
$pending_records = $result->where('status_id', 2)->get();
$closed_records = $result->where('status_id', 3)->get();

我的问题是 上的查询$active_records影响了$closed_records和上的查询$pending_records。

如何进行最后两个查询以引用原始$result查询？

Answer 1

我建议你不要做 4 db 查询，你可以只做一个查询，之后，你可以Laravel Collection用来过滤你的列表，所以你的代码将是这样的，并且确认$active_records不会影响$closed_records：

$result = Model::whereBetween('created_at', [$date_from, $date_to])->get();

$active_records = $result->where('status_id', 1);
$pending_records = $result->where('status_id', 2);
$closed_records = $result->where('status_id', 3);

Answer 2

你可以这样做

$result = Model::whereIn('status_id', [1, 2, 3])
    ->whereBetween('created_at', [$date_from, $date_to])
    ->get();

$active_records = $result->where('status_id', 1);
$pending_records = $result->where('status_id', 2);
$closed_records = $result->where('status_id', 3);
