PDFTemplate - Grandchild relationship

[item]

So this work ... not really good coding .. but you can adapt :

service/ contact.php

<?php
namespace Espo\Custom\Services;

use Espo\ORM\{
Entity,
EntityManager,
ServiceFactory,
};

class Contact extends \Espo\Modules\Crm\Services\Contact
{
protected function contactFromParent(Entity $entity)
{
$em = $this->getEntityManager();
$contactId = $entity->id;
$parentAccountId = $entity->get('accountId');

$account = $em->getEntity('Account', $parentAccountId);
$contacts = $em->getRepository('Account')
->getRelation($account, 'contacts')
->order('name')
->find();


foreach ($contacts as $contact) {

$contactFromParentList[$contact->id]['name'] = $contact->get('name');
}


$parentContactJson = json_decode(json_encode($contactFromParentList, true));

$entity->set('parentContactJson',$parentContactJson );
}
public function loadAdditionalFields(Entity $entity)
{
parent::loadAdditionalFields($entity);
$this->contactFromParent($entity);

//$GLOBALS['log']->warning( $entity->get('calls' ) );
}

public function loadAdditionalFieldsForPdf(Entity $entity)
{
$this->loadAdditionalFields($entity);

}

}

i have forget the cruxial : need to add in metadata a custom field :

entityDefs/contact :

important is jsonArray and notStorable .. other i don't know

"parentContactJson": {
"type": "jsonArray",
"notStorable": true,
"layoutDetailDisabled": true,
"layoutFiltersDisabled": true,
"layoutListDisabled": true,
"reportDisabled": true
} 

en in pdf :

{{#each parentContactJson}}
{{name}}

{{/each}}


Please choose better "word" for field

i will try then i come..

Thank you so much item. I gave this a try but failed. I create a Contact.php file with the code.

File:

 /custom/Espo/Custom/Services/Contact.php

Getting this error on rebuild:

Server side error 500: Class Espo\Custom\Services\Contact does not exist

As for the code all I did was change the word Specifications to Account

public function getEntityAccountList(Entity $entity)
{
$pdo = $this->getEntityManager()->getPDO();
$accountList = [];

$sql = "
SELECT DISTINCT `id`, `seconds`, `type`
FROM `account`
WHERE
`entity_type` = ".$pdo->quote($entity->getEntityType())." AND
`entity_id` = ".$pdo->quote($entity->id)." AND
`deleted` = 0
ORDER BY `seconds` ASC
";

$sth = $pdo->prepare($sql);
$sth->execute();
$rows = $sth->fetchAll(\PDO::FETCH_ASSOC);

foreach ($rows as $row) {
$o = new \StdClass();
$o->id = $row['id'];
$o->seconds = intval($row['seconds']);
$o->type = $row['type'];
$accountList[] = $o;
}
return $accountList;
}

public function loadAdditionalFields(Entity $entity)
{
parent::loadAdditionalFields($entity);
$this->loadAccountsField($entity);
}

protected function loadAccountsField(Entity $entity)
{
$specifications = $this->getRepository()->getEntityAccountList($entity);
$entity->set('account', $accounts);
}

Looking at other file in the folder, it seem like I need to do something like this:

<?php

namespace Espo\Custom\Services;

class Contact extends \Espo\Core\Templates\Services\BasePlus
{
}

But this where I have no idea what to do next. Thank you very much.

Hello,
look : loadAdditionalFields

step :
in service of your entity contact :

public function getEntitySpecificationList(Entity $entity)
{
$pdo = $this->getEntityManager()->getPDO();
$specificationList = [];

$sql = "
SELECT DISTINCT `id`, `seconds`, `type`
FROM `specification`
WHERE
`entity_type` = ".$pdo->quote($entity->getEntityType())." AND
`entity_id` = ".$pdo->quote($entity->id)." AND
`deleted` = 0
ORDER BY `seconds` ASC
";

$sth = $pdo->prepare($sql);
$sth->execute();
$rows = $sth->fetchAll(\PDO::FETCH_ASSOC);

foreach ($rows as $row) {
$o = new \StdClass();
$o->id = $row['id'];
$o->seconds = intval($row['seconds']);
$o->type = $row['type'];
$specificationList[] = $o;
}
return $specificationList;
}

public function loadAdditionalFields(Entity $entity)
{
parent::loadAdditionalFields($entity);
$this->loadSpecificationsField($entity);
}

protected function loadSpecificationsField(Entity $entity)
{
$specifications = $this->getRepository()->getEntitySpecificationList($entity);
$entity->set('specification', $specifications);
} 

and in your pdf :

{{#each specification}}

for your request is no need sql.. you can use orm.
for info, specification is not a field in entity ..

Reading this thread it seem like it is possible to get the grandchild (not sure if this correct term) of an entity: https://forum.espocrm.com/forum/deve...nd-grand-child

But that is for Query not for PDF Template Printing.

Anyway here is an example data:

PDF Template on Contact
(For entity Contact)
Contact Name: Mr John Smith
Contact Account: EspoCRM
Account Title: Director

(For entity Account)
Account name: EspoCRM
Relationship: Mr John Smith - Director
Relationship: Mr Stuart Smith - Engineer
Relationship: Ms Jane Smith - Finance

And here is what I'm trying to do.

When I print John Smith PDF, I also want to know what other contact is in the Account EspoCRM. I tried variation code like so but it doesn't seem to work, only added 3 method below otherwise I tried about 10 variation.

This would get me the Contact information

{{#each accounts}}
{{name}} -  {{contactRole}}
{{/each}}

Now to try and get "grandchild"

Test 1

{{#each contacts.accounts}}
{{name}} -  {{contactRole}}
{{/each}}

Test 2

{{#each accounts.contact}}
{{name}} - {{contactRole}}
{{/each}}

Test 3

{{#each accounts}}
{{name}} - {{contactRole}}
{{#each contacts.accounts}}
{{name}} - {{contactRole}}
{{/each}}
{{/each}}

Why not just go into Account and use this code?

{{#each contacts}}
{{name}} -  {{contactRole}}
{{/each}}

Because I want to get Contact information as well. And there is more information I want from Account not just the name and Role.

If anything not clear please let me know. Appreciate if anyone know on a how-to solve this.
