How to show or display related posts based on category in laravel

Suppose i have two table one is posts and another is categories. Now i want to show related posts by using category in laravel.

At first we need to make a relation both Category and Post model. 

In Category model we use: hasMany relation in Category.php

    public function posts(){
        return $this->hasMany('App\Post');
    }
In Post model we use: belongsTo in Post.php
    public function category(){
        return $this->belongsTo('App\Category');
    }


For showing data we need create route and controller: suppose i have create a 

BlogController.php and make a route as blew


#web.php


Route::get('/post/{slug}', [
    'uses' => 'BlogController@show',
    'as' => 'post.single'
]);


# BlogController.php


    public function show($slug){
        $post=Post::where('slug',$slug)->first();
        $categories=Category::all();
        $related= Post::where('category_id', '=', $post->category->id)->where('id', '!=', $post->id)->get();
        return view('post.single')->with('post',$post)
            ->withCategories($categories)
            ->withRelated($related);
    }


Now we will show or display related post in view blade 


#single.blade.php


	@if(empty($related))
<p style="color:red;"> Sorry ! No Related Post Found.</p>
@else
<div class="related-posts section-title">
<h2><span>Related Posts</span></h2>
<div class="row">
@foreach($related->take(6) as $relate)
<div class="col-md-4">
<a class="related-items" href="{{route('post.single',['slug' =>$relate->slug])}}">
<img src="/storage/{{$relate->image}}" class="img-thumbnail" alt="{{$relate->title}}"/>
</a>
</div>
@endforeach
</div>
</div> <!--related-posts-->
@endif


It will show related product on running category posts. In that way you can show related post or product by laravel
