Getting recommendation for similar posts based on user likes

[Kyzegs]

I came across this package today and I'm struggling to figure out exactly how to use it to achieve what I want. I'm aiming to develop a feature where I can recommend posts to users based on the content of the posts they've previously liked.

Hi @Kyzegs ,

Many thanks for the question. Your case is very similiar to the Usecase 1 at README. So, for your case your Post model should as follows;

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Umutphp\LaravelModelRecommendation\InteractWithRecommendation;
use Umutphp\LaravelModelRecommendation\HasRecommendation;

class Post extends Model implements InteractWithRecommendation
{
    use HasFactory, HasRecommendation;

    public static function getRecommendationConfig() :array
    {
        return [
            'like' => [
                'recommendation_algorithm'         => 'db_relation',
                'recommendation_data_table'        => 'likes',
                'recommendation_data_table_filter' => [],
                'recommendation_data_field'        => 'post_id',
                'recommendation_data_field_type'   => self::class,
                'recommendation_group_field'       => 'user_id',
                'recommendation_count'             => 5
            ]
        ];
    }
}

And the function calls should be as follows;

<?php
...

use App\Model\Post;

Post::generateRecommendations('like');

$post        = Post::find(1);
$recommendations = $post->getRecommendations('like');

I hope it helps :)

But this only creates a recommendation based on a singular post, right? I would like to generate recommendations based on a set of liked posts of a user.

This generates the recommendation based a singular posts as you said. It generates the recommendation from the list of posts that is liked with the post.

You want to get a recommendation based on the set of user's likes. This package does not gives that. But, It is a good feature to be added 👍🏻. Let me create an issue and start planning. But, I am not sure if I can do it in short time.
