Database Searching Using Doctrine and Symfony2 - symfony

Question

So I'm currently trying to perform a simple search using Symfony2 and Doctrine. Something similar to this: http://docs.doctrine-project.org/projects/doctrine1/en/latest/en/manual/searching.html
I've currently got the following YAML file setup to generate my entities. It generates my class Style entity correctly as a class.
...\Style:
type: entity
table: styles
id:
id:
type: integer
generator:
strategy: IDENTITY
actAs:
Searchable:
fields: [title]
batchUpdates: true
fields:
title:
type: string
length: 150
unique: true
In my controller, I'm trying to run a search on that table based on a string.
public function searchAction($pattern)
{
$repository = $this->getDoctrine()->getRepository('..:Style');
$search = $repository->search($pattern);
return $this->outputize($search);
}
However, when I try executing the code, I get the following exception.
Undefined method 'search'. The method name must start with either findBy or findOneBy!
Am I generating my entities correctly or is there something I'm clearly missing?
On a side note, when I look at my Entity/Style.php after generating, there is no clear method ->search(), is the function supposed to be generated by Symfony here?

Answer 1

search() is not a function supported in Symfony2. You're looking at the Symfony 1.x documentation, and Symfony2 is really different from Symfony 1.x so for reference, you should always use the doc.
There are several ways to fetch entities in Symfony2. Here are a few examples:
Find
$user = $this->getDoctrine()
->getRepository('UserBundle:User')
->find($user_id)
;
DQL:
$query = $em->createQuery(
'SELECT b FROM YourBundle:Bid b WHERE b.property_id = :property_id ORDER BY b.amount DESC'
)->setParameter('property_id', $property_id);
try {
$bids = $query->getResult();
} catch (\Doctrine\Orm\NoResultException $e) {
//Handle No Result Exception here
}
Refer to the Doctrine guide for Symfony2 here: http://symfony.com/doc/current/book/doctrine.html

Hello you can do it in symfony 3
$em = $this->getDoctrine()->getManager();
$query = $em->createQuery(
'SELECT p
FROM AppBundle:Hotel p
WHERE p.address like :location
ORDER BY p.address ASC'
)->setParameter('location','%'.$request->get('location').'%' );
$hotel = $query->getResult();
