如何在 laravel 的 withCount 中添加 having 子句？

Question

我想获取包含 2022-05-12 23:59:59 之前创建的评论总数的帖子。我也有附加的时区过滤器。我尝试了以下方法：

Route::get('/', function () {
  $base = Post::withCount([
    'comment' => function ($query) {
      $query->select(
        'id',
        'post_id',
        DB::raw('convert_tz(created_at, "UTC", "US/Eastern") as created_at_tz')
      )->having('created_at_tz', '<=', '2022-05-12 23:59:59')->count();
    },
  ]);


  return $base->get();
});

我收到错误：

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'posts.id' in 'where clause'

select
  count(*) as aggregate
from
  (
    select
      convert_tz(created_at, "UTC", "US/Eastern") as created_at_tz
    from
      `comments`
    where
      `posts`.`id` = `comments`.`post_id`
    having
      `created_at_tz` <= 2022 -05 -12 23: 59: 59
  ) as `temp_table`

我做错了什么？

Answer 1

...
->withCount([
    'comment' => function ($query) {
        $query->whereRaw('convert_tz(created_at, "UTC", "US/Eastern") <= '2022-05-12 23:59:59'));
    }])
...

试试这个并用回复更新我

我认为最后没有必要计数
