将两个查询合并在一起sortByDesc和paginate
我正在构建一个报告系统，用户可以在其中报告违反了要审核站点规则的内容。
表格
帖子
- id（int）
- user_id（int）
- 内容（文字）
- 标题（文本）
- created_at
评论
- id（int）
- 内容（int）
- user_id（int）
- post_id（int）
- created_at
报告
- id（int）
- user_id（int）
- 内容（文本）
- reportable_id（int）
- reportable_type（字符串）
用户
- id（int）
- 名称（字符串）
我要做什么
我想做的是同时查询具有报告的帖子和评论，渴望加载报告，将帖子和评论合并在一起，在帖子和评论模型上sortByDesc('created_at')，最后对合并的查询进行分页。
ReportController尝试
public function index()
{
$posts = Post::whereHas('reports')
->with('reports.user')
->get();
$comments = Comment::whereHas('reports')
->with('reports.user', 'post')
->get();
//I have no idea how to paginate this.
return $postAndCommentReports = $posts->merge($comments)->sortByDesc('created_at');
}
查询输出

正如您从输出sortByDesc('created_at);中看到的那样，它不起作用，我绝对不知道如何对它进行分页。
尝试2
我还尝试查询所有报告并将这些报告分组在一起。
$reports = Report::with('reportable','user')->latest()->paginate();
return $reports->groupBy('reportable_id');

以下是显示我要获取的输出的图像：
是否有一种相对有效的方法？ Do I have to do a raw query on the DB and use Union and join like this other thread?，以及如何对输出进行分页？有什么方法可以组织或分解报告表以更好地处理此问题？
