workflow service action parameters, and how to find error message.

[Patrick]

according to : https://www.espocrm.com/features/add...-for-workflow/

We can add service action to a workflow.

My Question is the parameters of the function:

<?php

namespace Espo\Custom\Services;

use \Espo\ORM\Entity;

class TestService extends \Espo\Core\Services\Base
{
    public function testServiceAction($workflowId, Entity $entity, array $additionalParameters = null)
    {
        //your code here
    }
}

what is $entity?

when I try to print_r on $entity, it gives me 'server 500'


How to debug Service Action, where to find its errors?

Entity is the target object workflow is applied to. In example it's a Call. Error 500 is normal when printing such objects.

Thank you for your reply, You have done a great work for EspoCRM by the way.


I have a customer entity, derived from Base, with two fields, 'name' and 'ticket'. The ticket is obtained from a remote server base on the name value. I wish to update the ticket value whenever the name is changed.

My Problem is:

I fall into a dead-loop, as I cannot do 'save' entity, in 'after-save' trigger.
I can add if named 'changed' condition, it works for existing record, but it still dead-loop for 'newly created' record.

This might be suited to read-only field that calculated by formula, any guide on define custom function in formula?

Hi Patrick,

Could you attach a screenshot of your workflow detail view? Maybe you are changing the name field in workflow that triggers on thie name field change?

[Patrick]

Hi Yuri,

attached is screenshot..

            //Service Action function body

             $entityManager = $this->getEntityManager();

             $name = $entity->get("name");

             //...
             //get ticket by 'name' using php-curl
             .....

             $entity->set("ticket", $ticketValue);

             $entityManager->saveEntity($entity); //

[yuri]

$entityManager->saveEntity($entity, array('skipWorkflow' => true));

[Patrick]

Great, problem solved.

Any method to create attachment inside Service Action routine?


I stuck at : $this->getFileStorageManager()->putContents

( $this is \Espo\Core\Templates\Services\Base )

        

        $attachment = $this->getEntityManager()->getEntity('Attachment');
        $attachment->set("name", $filename);
        $attachment->set("type", $mime);
        $attachment->set("size", $size);
        $attachment->set("role", "Attachment");
        $this->getEntityManager()->saveEntity($attachment);

   --------------------
          |
          |

        ///this statement cause error when trying to create attachment content in Service Action routine.
        $this->getFileStorageManager()->putContents($attachment, $contents);

        return $attachment->id;
    }

I end up with a lots of empty 'attachment id' which has no content at all.

I solved it by adding the following code at the begining of Service Action Class.

    protected function init()
    {
        parent::init();
        $this->addDependencyList([
            'container',
            'preferences',
            'fileManager',
            'crypt',
            'serviceFactory',
            'fileStorageManager'
        ]);
    }

    protected function getFileStorageManager()
    {
        return $this->getInjection('fileStorageManager');
    }
