Laravel-根据何处原因进行表联接和计数

Question

我正在一个项目上，我的代码开始变得混乱。

当前我的控制器上有以下内容

$rollmonth = Rollmapping::latest()->value('roll_month');

    $officerwk1 = DB::table('roll')
            ->join('rollmapping', "roll.roll_id", "=", "rollmapping.id")
            ->join('members', 'roll.member_id', '=', 'members.id')
            ->where('rollmapping.roll_month','=', $rollmonth)
            ->where('roll.status', '!=', 'A')
            ->where('members.rank', '<', 12)
            ->where('rollmapping.roll_week', '=', 1)
            ->get();

问题是我要重复5次（每月的每个星期） 唯一的改变是

->where('rollmapping.roll_week', '=', 1)

每周1、2、3、4、5，

我还将为每个等级组（它们是4）重复一次

例如 WO / TO将具有以下内容：

->wherebetween('members.rank', [12,13])

NCO将具有以下内容：

->wherebetween('members.rank', [14,18])

学员将具有以下内容：

->where('members.rank', '>', 18)

这将导致25个不同的变量，这不合适 使用模型必须有更好的方法

转台

|id|roll_id|member_id|status|

映射表

|id|roll_date|roll_year|roll_month|roll_week|

会员表

|id|first_name|last_name|rank|.....

当然，必须有一个更好的解决方案来提供25个不同的变量，这些变量将显示为类似这样的计数

|         |Week 1|Week 2|Week 3|week 4|week 5|Totals|
|Offciers |Count  Count  Count  Count  Count |Total |
|TO/WO    |Count  Count  Count  Count  Count |Total | 
|NCO's    |Count  Count  Count  Count  Count |Total |
|Cadets   |Count  Count  Count  Count  Count |Total |
|Total    |Total  Total  Total  Total  Total |Total |

此刻我的桌子看起来像这样；

<table class="table">
                        <tr>
                            <th class="text-center">Details</th>
                            <th class="text-center">Week 1</th>
                            <th class="text-center">Week 2</th>
                            <th class="text-center">Week 3</th>

                            <th class="text-center">Week 5</th>
                            <th class="text-center">Total</th>
                        </tr>
                        <tr>
