How to pull information based on an ID? - symfony

Question

I have a entity Article20000Information, with a few fields like: id, description, manufacturer_id, supplier_id
I have another entity, Organisation. It has a list of companies (both manufacturers & suppliers) each with an id.
I also have a page which renders a list of Article20000Information data. Currently, it simply displays the data in the table so:
| id | Description | Manufacturer | Supplier | Price |
|----|-------------|--------------|----------|--------|
| 1 | thing1 | 2 | 5 | 34 |
| 2 | thing2 | 5 | 2 | 23 |
| 3 | thing3 | 3 | 4 | 25 |
What I need is for the manufacturer and supplier column to display the name value from the organisation table, based on the id shown.
What is the best way to go about this?

Answer 1

Got it!
I needed multiple aliases, which I'd guessed, but I also needed to give them AS so that they come out with different column names. This in turn lets twig render the tags.
<?php
namespace Regenerys\QMSBundle\Entity;
use Doctrine\ORM\EntityRepository;
class Article20000InformationRepository extends EntityRepository
{
public function findStuff()
{
return $this->getEntityManager()
->createQuery(
'SELECT
A.id,
A.articleNumber,
A.description,
B.name as manufacturer,
C.name as supplier
FROM
RegenerysQMSBundle:Article20000Information A
LEFT OUTER JOIN RegenerysQMSBundle:Organisation B WITH B.id = A.manufacturer
LEFT OUTER JOIN RegenerysQMSBundle:Organisation C WITH C.id = A.supplier '
)
->getResult();
}
}
Thanks to #Alexandru for his DQL help.

You need to join the two tables based on id condition.
select A.id, A.Description, B.ManufacturName, B.supplierName
from Article20000Information A
left outer join Organisation B
ON B.id = A.id

If you are using doctrine, a proper way is to create a Repository class, and there write your joined code proposed by #K139 but in DQL:
class Article20000InformationRepository extends EntityRepository
{
public function findAll()
{
return $this->getEntityManager()
->createQuery(
'SELECT A.id, A.Description, B.ManufacturName, B.supplierName FROM AppBundle:Article20000Information A
LEFT OUTER JOIN AppBundle:Organisation B ON B.id = A.id '
)
->getResult();
}
}
Then in your controller you will use it:
$articles = $em->getRepository('AppBundle:Article20000Information')->findAll();
