【问题描述】：
我正在使用 Laravel 5.8 创建博客。我创建了一个包含导航栏、侧边栏和页脚的主布局。休息区在后续布局中产生。由于我在主布局文件中包含了侧边栏，我的查询是如何从数据库中加载侧边栏中的类别。
目前的情况是：我将类别保持不变。
主布局：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="author" content="Aarthna Maheshwari" />
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" />
<meta name="description" content="A fully functional blog made from scratch using HTML5, CSS3, Javascript, Boostrap and Laravel In India" />
<link rel="stylesheet" type="text/css" href="{{asset('/css/bootstrap.min.css')}}" />
<link rel="stylesheet" type="text/css" href="{{ asset('/css/blog.css') }}" />
<link href="https://fonts.googleapis.com/css?family=Playfair+Display:700,900" rel="stylesheet" />

预期输出： 应用应从数据库中加载类别。
