Php 基于日期groupBy类型的查询计数-Laravel

我的目标是构建这些数据

753 它现在可以工作了，但是它做了很多查询来得到我需要的东西

我试过了 我现在有点困了

如何优化查询？

您可以在PHP端进行分组：

$logs = BabyLog->where('babyId',$baby->id)->get()->groupBy(function ($log) {
   return $log->updated_at->format('y-m-d');
});

foreach($logs as $date => $logsOnThatDay) {
   // here on you can probably use the code you already have but this below might be shorter
   $graphData[$date] = $logsOnThatDay->reduce(function ($acc, $log) {
      if (array_key_exists($log->type, $acc)) { $acc[$log->type]++; }
       return $acc;
   }, [
      'pee' => 0,
      'poop' => 0,
      'feed' => 0,
      'medicine' => 0,
      'sleep' => 0,

   ]);
   
}

在不需要的时候，您仍然在循环中运行查询。将所有这些添加到第一个查询中，并将其从循环中删除。但是，如果我将其拉出，我将如何访问所有日期

$logDate

如果您想建议您的查询，我将立即尝试。让我试试。。结果：我在null上得到了对成员函数format（）的

调用

我有一个输入错误，意思是说

更新了

不是我写的乱七八糟的东西也忘了添加更新到现在的提要

$logs = BabyLog::whereDate('updated_at', '=', date('Y-m-d H:i:s'))
->whereIn('type', ['feed', 'pee', 'poop','medicine','sleep'])
->selectRaw('type, count(type) as count')
->groupBy('type')
->get()
->keyBy('type');

$logs = BabyLog->where('babyId',$baby->id)->get()->groupBy(function ($log) {
   return $log->updated_at->format('y-m-d');
});

foreach($logs as $date => $logsOnThatDay) {
   // here on you can probably use the code you already have but this below might be shorter
   $graphData[$date] = $logsOnThatDay->reduce(function ($acc, $log) {
      if (array_key_exists($log->type, $acc)) { $acc[$log->type]++; }
       return $acc;
   }, [
      'pee' => 0,
      'poop' => 0,
      'feed' => 0,
      'medicine' => 0,
      'sleep' => 0,

   ]);
   
}
