The generateRecommendations method is not working

[Xoshbin]

Hi, I'm trying to test this package, but my issue is the generateRecommendations mehtod is not generating anything and it's not giving any errors too. Is there anyway to see the progress of the model generation. My table contains around 70,000 rows just for testing purposes. as I said I no errors no progress and nothing generated in the table too. I have tried with both "similiarity and db_relation" methods.

Hi @Xoshbin ,

I need more details to fix the issue. Is it possible to give me the Model definition and the migration for the table?

Hi @umutphp ,
The model is a little bit complex, so i tried to cleand it as much as needed:

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

    /**
     * The attributes that are mass assignable.
     *
     * @var string[]
     */
    protected $fillable = [
        'type',
        'title',
        'url',
        'status',
        'postable_type',
        'postable_id',
        'created_at',
        'updated_at',
    ];

    /**
     * Get the parent postable model (user or page).
     */
    public function postable()
    {
        return $this->morphTo();
    }

    public static function getRecommendationConfig() :array
    {
        return [
            'similar_products' => [
                'recommendation_algorithm'            => 'similarity',
                'similarity_feature_weight'           => 1,
                'similarity_numeric_value_weight'     => 1,
                'similarity_numeric_value_high_range' => 1,
                'similarity_taxonomy_weight'          => 1,
                'similarity_feature_attributes'       => [
                    'title'
                ],
//                'similarity_numeric_value_attributes' => [
//                    'price'
//                ],
                'similarity_taxonomy_attributes'      => [
                    [
                        'postable' => 'name'
                    ]
                ],
                'recommendation_count'                => 2,
                'recommendation_order'                => 'desc'
            ]
        ];
    }
}

And here's the migration:

    Schema::create('posts', function (Blueprint $table) {
            $table->uuid('id')->primary();
            $table->string('type');
            $table->string('status');
            $table->string('title');
            $table->string('url')->unique();
            $table->uuidMorphs('postable');
            $table->timestamps();
        });

I'm trying to depend mostly on the title field for now, I want to test if I can make the reommendations based on the title
And I tried with the "db_relation", Have no results too.

Let me check at my local and update you.

[Xoshbin]

Thank you

And I forgot to say, that I have forked the package and changed collections and contracts packages to version 9.0 to work on a Laravel 9 project.

"illuminate/collections": "^9.0",
"illuminate/contracts": "^9.0",

@Xoshbin A PR would be appreciated to do this upgrade :)

[Xoshbin]

Sure I will do.

@Xoshbin I have created the Post model on my local with your recommendation setups. I have created 100 posts with faker lib. I have executed Post::generateRecommendations('similar_products'); command to generate the recommendations. It did not verbose anything but generated the recommendation. Can you please check the laravel_model_recommendation_table table on your local.

[Xoshbin]

No, I check it every time after running the command, there's nothing in the table.

[umutphp]

Can you please also share the postable table?

[Xoshbin]

Page model:

class Page extends Model
{
    use HasFactory;
    use HasUuids;
    /**
     * The attributes that are mass assignable.
     *
     * @var string[]
     */
    protected $fillable = [
        'name',
        'url',
        'description',
    ];

    /**
     * Get the page's posts.
     */
    public function posts()
    {
        return $this->morphOne(Post::class, 'postable');
    }
}

User model:

class User extends Authenticatable
{
    use HasFactory;
    use Notifiable;
    use HasUuids;

    /**
     * The attributes that are mass assignable.
     *
     * @var string[]
     */
    protected $fillable = [
        'name',
        'email',
        'role',
        'password',
        'url',
        'description'
    ];

    /**
     * The attributes that should be cast.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    /**
     * Get the user's post.
     */
    public function posts()
    {
        return $this->morphOne(Post::class, 'postable');
    }
}

Hi @Xoshbin ,

Everything worked correctly at my local. So, I could not reproduce the case. I added some extra logs to the package and created a new version v0.2.5.

You can upgrade the package on your project and set the log level as debug. I hope the logs helps us to find the root cause.

Hi @umutphp ,
Sorry I was busy last two days. I will check it. Thank you.
