Overview

In cases where relationships exist between entities, it’s vital to define them explicitly in the model.

Following example demonstrates how to define relationships between users by incorporating an $id and $coworkers fields.

​
Example

<?php

$loader = require 'vendor/autoload.php';

$loader->add('Cognesy\\Instructor\\', __DIR__.'../../src/');



use Cognesy\Instructor\Enums\Mode;

use Cognesy\Instructor\Instructor;



class UserDetail

{

    /** Unique identifier for each user. */

    public int $id;

    public int $age;

    public string $name;

    public string $role;

    /**

     * @var int[] Correct and complete list of coworker IDs, representing

     * collaboration between users.

     */

    public array $coworkers;

}



class UserRelationships

{

    /**

     * @var UserDetail[] Collection of users, correctly capturing the

     * relationships among them.

     */

    public array $users;

}



$text = "Jason is 25 years old. He is a Python programmer of Apex website.\

 Amanda is a contractor working with Jason on Apex website. John is 40yo\

 and he's CEO - Jason reports to him.";



$relationships = (new Instructor)->respond(

    messages: [['role' => 'user', 'content' => $text]],

    responseModel: UserRelationships::class,

);



dump($relationships);



assert(!empty($relationships->users));
