Doctrine won't add persist entity relationship

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?

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.

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...

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();

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.
