如何使用拉拉维尔将产品显示到相关类别

Question

我正在尝试显示与该类别相关的产品。在我的菜单中，我有一个类别列表，如果我单击此类别，我想查看与此类别相关的产品。我只是在学习拉拉维尔，有人可以帮助我吗？

数据库：

-category: id, cate_name ,p_id
-product: has Category_id

产品型号：

namespace App;
use IlluminateDatabaseEloquentModel;
class product extends Model
{
protected $fillable = [ 'id', 'product_name', 'product_price', 'product_image', 
'product_brand'];
}

品类型号：

namespace App;
use IlluminateDatabaseEloquentModel;
class category extends Model
{
public $table = "category";
public function childs()
{
return $this->hasMany('Appcategory','p_id');
}
}

类别视图：

<div class="nav-panel__nav-links nav-links">
<ul class="nav-links__list">
@foreach(Appcategory::with('childs')->where('p_id',0)->get() as $firstmenu)
<li class="nav-links__item  nav-links__item--has-submenu ">
<a id="cate" class="nav-links__item-link" href="{{$firstmenu->cate_name}}">
<div class="nav-links__item-body">
{{$firstmenu->cate_name}}
<svg class="nav-links__item-arrow" width="9px" height="6px">
<use xlink:href="public/assets/images/sprite.svg#arrow-rounded-down-9x6"></use>
</svg>
</div>
</a>
<div class="nav-links__submenu nav-links__submenu--type--megamenu nav- 
links__submenu--size--nl">
<!-- .megamenu -->
<div class="megamenu ">
<div class="megamenu__body">
<div class="row">
@foreach($firstmenu->childs as $secondmenu)
<div class="col-6">
<ul class="megamenu__links megamenu__links--level--0">
<li class="megamenu__item  megamenu__item--with-submenu ">
<a href="">{{$secondmenu->cate_name}}</a>
<ul class="megamenu__links megamenu__links--level--1">
@foreach($secondmenu->childs as $thirdmenu)
<li class="megamenu__item"><a href="">{{$thirdmenu->cate_name}}</a></li>
@endforeach
</ul>
</li>
</ul>
</div>
@endforeach
</div>
</div>
</div>
<!-- .megamenu / end -->
</div>
</li>
@endforeach
</ul>
</div>
