Summary of how to display the number of likes in a list with Laravel

Laravel Framework 8.83.8
Vue 2.6

Premise

Assuming there is a posts table and a likes table, this content is specific to display.

Please refer to the following article for the "Like" feature.

How to Implement a "Like" Feature in Laravel

Writing a Relation in Laravel

From the Post model's perspective, since Like is one-to-many, write the relation with hasMany.

Models/Post.php

    public function likes()
    {
        return $this->hasMany('App\Models\Like');
    }

Setting the Number of Likes in the Controller to Retrieve the List

How to Count the Total of a Related Number and Display it in a List in Laravel【withCount】

(Routing configuration and blade file generation are omitted in the article)

    public function index()
    {
        $posts = Post::withCount('likes')->get();
        //dd($posts);
        return view('post/index',compact('posts'));
    }

With this description, the data is retrieved with the column "likes_count" added.

Displaying a List with blade×Laravel

Since the column has been added, it can be retrieved just like other columns.

@foreach($posts as $post)
<div>{{ $post->likes_count }}</div>
@endforeach

Displaying a List with Vue × Laravel

The relation and controller are the same, only the column has been added, so it can be easily retrieved as follows.

<template>
  <div v-for="post in posts">{{post.likes_count}}</div>
</template>

Conclusion

That's all.
