laravel-medailibrary getFirstMediaUrl("images") 不适用于连接表

Question

我在从 laravel-medailibrary 中加入的 table 获取媒体时遇到问题，我使用 getFirstMediaUrl("images") 从一个 table 获取照片并且它有效，但是如果我加入两个或三个 table 就不行了，我该如何解决？

我想从用户分享的 post 中获取照片。

这个posttable：

这是share_tb table:

这是用户 table:

这是媒体 table:

我尝试了一些方法后找到了答案：

public function getPosts(Request $request)
{


    $result = [];

    $postID = DB::table("share_tb")->where("user_id", Auth::user()->id)->get();

    foreach ($postID as $id) {

        if (count(Post::where("id", $id->related_id)->get()) > 0) {
            $posts = Post::where("id", $id->related_id)->get();
            foreach ($posts as $post) {

                // $result = $post->getMedia('images');
                array_push($result, [
                    "comment_count" => getTotalComment($post->id),
                    "course_id" => $post->course_id,
                    "id" => $post->id,
                    'post_image' => count($post->getMedia('images')) > 0 ? $post->getMedia('images')[0]->getFullUrl('big') : "",
                    'logo'=>GetCourseLogo::collection(Course::where('course_id',$post->course_id)->get()),
                    "post_author" => $post->post_author,
                    "post_date" => $post->post_date,
                    "post_excerpt" => $post->post_excerpt,
                    "post_modified" => $post->post_modified,
                    "post_parent" => $post->post_parent,
                    "post_title" => $post->post_title,
                    "post_type" => $post->post_type,
                ]);
            }
        }

    }
    return Response()->json($result);

}

通过这个资源收集，我得到了标志：

class GetCourseLogo extends JsonResource
  {
     public function toArray($request)
       {
          return $this->getFirstMediaUrl('logo');
       }
  }
