php - 如何使用 laravel db 查询为 sql 中的分组项命名？

Question

使用此代码我得到以下输出:

$q = DB::table('payments')
        ->join('agency', 'agency.id', '=', 'payments.agency')
        ->join('paymenttype','paypemttype.id', '=', 'payments.paymenttype')
        ->select(DB::raw('sum(payment) as sum'), 'agency.agency', 'paymenttype.paymenttype')
        ->where('payments.school', '=', Sentry::getUser()->school)
        ->groupBy('payments.agency')
        ->groupBy('payments.paymenttype')
        ->get();

输出是:

[
{
sum: 200,
agency: "city1",
paymenttype: "credit card"
},
{
sum: 200,
agency: "city1",
paymenttype: "transfer"
},
{
sum: 200,
agency: "city2",
paymenttype: "credit card"
},
{
sum: 200,
agency: "city2",
paymenttype: "transfer"
}
  ]

但是我想要那个城市位于表格的左侧，所以我想要这种输出

-   city1  [
{
sum: 200,
paymenttype: "credit card"
},
{
sum: 200,
paymenttype: "transfer"
}],
- city2 [
{
sum: 200,
paymenttype: "credit card"
},
{
sum: 200,
paymenttype: "transfer"
}
  ]

所以我的意思是对象中的对象我想获取这样的数据。 如果您能帮助我，我将非常高兴，感谢您再次提供帮助。

Answer 1

您可以使用keyBy方法。

由于您没有使用 Eloquent，因此您可以自己创建集合。

Laravel 5:

$result = collect($q)->keyBy('agency');

Laravel 4:

use Illuminate\Support\Collection;

$result = Collection::make($q)->keyBy('agency');
