Text summarization in EspoCRM

[Prathyush Shetty]

I have a Python script that summarizes any chunk of text. I want to call the script in the AfterSave hook of some entity let's say "leadhook.php". Is it possible? If yes, how can I do it?

I haven't tried this code but it's cobbled together from something similar we have. This assumes your script is under espocrm/custom/scripts. Also this is sloppy because you're passing something unsafe on the command line, but you get the idea.

<?php
namespace Espo\Custom\Hooks\Lead;

use Espo\ORM\Entity;
use Espo\Core\ORM\EntityManager;

class LeadHook
{
    private EntityManager $entityManager;

    public function __construct(private EntityManager $em)
    {
        $this->entityManager = $em;
    }

    public function afterSave(Entity $entity, $options): void
    {

        // use tempnam(), fopen(), fwrite() if you need
        // to process a temporary file, otherwise pass in field
        $params = $entity->get('fieldToSummarize') ?? "";
        $output = null;
        $workdir = dirname($_SERVER['CONTEXT_DOCUMENT_ROOT']);
        $command = "$workdir/scripts/myScript.py '$params' 2>&1";
        $output = shell_exec($command);

        $entity->set('summaryField', $output);
        $this->entityManager->saveEntity($entity);
    }

}

I'd recommend utilizing Symfony\Component\Process\Process. It's included in Espo.
