laravel - 有没有办法在没有数据的情况下返回 0 几个月？

Question

我正在使用 Chart.js 来显示每个月的交易总数(计数)。

$dataTotal = ModelName::select(DB::raw('count(id) as count'), DB::raw("MONTH(created_at)  as month")) 
                        ->where('org_id', auth()->user()->org_id)
                        ->where('result_code', 200)
                        ->groupBy('month')
                        ->orderBy('month')
                        ->get()
                        ->toArray();

查询本身是没问题的，除了如果一个月内没有记录则不返回 0的问题。那个月。这导致图形无法正确呈现。
有没有人对我如何实现它以便我收到完整的结果集有任何建议？
所需的格式是:

array (
0 => 
array (
  'count' => 0,
  'month' => 1,
),
1 => 
array (
  'count' => 5,
  'month' => 2,
),
2 => 
array (
  'count' => 0,
  'month' => 3,
),
3 => 
array (
  'count' => 4,
  'month' => 4,
),
4 => 
array (
  'count' => 0,
  'month' => 5,
),
5 => 
array (
  'count' => 4,
  'month' => 6,
),
6 => 
array (
  'count' => 51225,
  'month' => 7,
),
7 => 
array (
  'count' => 4,
  'month' => 8,
),
8 => 
array (
  'count' => 0,
  'month' => 9,
),
9 => 
array (
  'count' => 0,
  'month' => 10,
),
10 => 
array (
  'count' => 0,
  'month' => 11,
),
11 => 
array (
  'count' => 0,
  'month' => 12,
),

)

$monthlyArray = array();
$emptyMonth = array('count' => 0, 'month' => 0);
for($i = 1; $i <= 12; $i++){//generate an array with default values
    $emptyMonth['month'] = $i;
    $monthlyArray[$i-1] = $emptyMonth;

}

$dataTotal = ModelName::select(DB::raw('count(id) as count'), DB::raw("MONTH(created_at)  as month")) 
                        ->where('org_id', auth()->user()->org_id)
                        ->where('result_code', 200)
                        ->groupBy('month')
                        ->orderBy('month')// you don't really need this one 
                        ->get()
                        ->toArray();//fetch the results

foreach($dataTotal as $key => $array){//add the results to the default array
    $monthlyArray[$array['month']-1] = $array;
}
//monthlyArray contains the data
