Doctrine won't add persist entity relationship - php

Question

I have two entities, View and Location
Each View can have a Location.
In my view I thus have:
class View
{
//..... Other Stuff.....
/**
* #ManyToOne(targetEntity="Location", inversedBy="views")
**/
private $location;
//...setters and getters....
public function setLocation($location){
$this->location = $location;
}
}
and then for my Location
class Location
{
//.....other stuff.....
/**
* #OneToMany(targetEntity="View", mappedBy="location")
**/
private $views;
public function __construct() {
$this->created = $this->updated = new \DateTime("now");
$this->views = new \Doctrine\Common\Collections\ArrayCollection();
}
// .... Getters and Setters ....
}
But when I try and do this:
<?php
$this->pageview = $this->em->getRepository('Entities\View')->find(1);
$this->location = $this->em->getRepository('Entities\Location')->find(1);
$this->pageview->setLocation($this->location);
$this->em->persist($this->pageview);
$this->em->flush();
?>
Or even when I create new entities:
<?php
$pv = new Entities\Pageview;
$lc = new Entities\Location;
$this->em->persist($lc);
$this->em->flush();
$pv->setLocation($lc);
$this->em->persist($pv);
$this->em->flush();
?>
Doctrine never sets the location_id in the database (it is always NULL).
I've checked the SQL queries and they're not even being attempted at being set, all I'm getting is:
INSERT INTO View (field1, field2, created, updated) VALUES ('val1', 'val2', '2013-07-17T12:10:56+01:00', '2013-07-17T12:10:56+01:00')
No reference to locations whatsoever...The weird thing is I can update field1 and field2 fine...and all other relations are working throughout my application...I just can't get views and locations to work...
EDIT
I have the exact some code working now on another computer. I don't know why it wasn't working, but I just moved the files back and restarted my computer and now it is...cacheing problem I guess?

Answer 1

Restarted my computer and the problem got solved...I don't know why it was going wrong!
Maybe something to do with caches or proxies...I dunno...

Answer 2

You could try explicitly referencing the correct columns that Doctrine needs to do a join on.
/**
* #ManyToOne(targetEntity="Location")
* #JoinColumn(name="location_id", referencedColumnName="id")
*/
private $location;
Also, in this example:
$this->pageview = $this->em->getRepository('Entities\View')->find(1);
$this->location = $this->em->getRepository('Entities\Location')->find(1);
$this->pageview->setLocation($this->location);
$this->em->persist($this->pageview);
$this->em->flush();
You do not need to persist the entity if you are just updating the existing data.

Answer 3

I think you need load the view in the location. So you must create a method in your Location entity like this:
public function getViews() {
return $this->views;
}
and then to persist into database, do this:
$location = new Entity\Location();
$view = new Entity\View();
$location->getViews()->add($view);
$this->em->persist($location)
$view->setLocation($location);
$this->em->persist($view);
$this->em->flush();

This is related to the Doctrine ORM cache drivers:
doctrine:
orm:
entity_managers:
default:
metadata_cache_driver: apcu
result_cache_driver: apcu
query_cache_driver: apcu
We used APCu to even on DEV do caching, clearing APCu (by restarting Apache) did the trick.
