如何从嵌套中获取对象Eager Loading Laravel？ [英] How to get object from nested Eager Loading Laravel?

问题描述

在查询中我使用Nested Eager Loading：

In query I use Nested Eager Loading:

$res = User::where("id", 1)->with("categories.categoryAnn.announcements")->get();

在此查询的结果中，我收集了嵌套集合：

In result of this query I get nested collections:

Collection->User->categories->categoryAnn->announcements

如何尽快获取最后一个嵌套对象通知？

How to shortly get last nested object announcements?

推荐答案

你可以用相反的方法来获得这样的公告：

You can do it the opposite way to get only announcements like this:

$announcements =  Announcement::whereHas('categoriesAnn', function($q) {
  $q->whereHas('categories, function($q) {
      $q->whereHas('user', function($q) {
          $q->where('id',1);
      });
  });
});

这显然是伪代码，因为我不知道你的关系的确切名称，工作，你不需要任何循环。

This is obviously pseudocode, because I don't know exact names of your relationships but something like this should work and you don't need any loops here.
