Serialized proxy classes Doctrine 2

Is there a possibility to get the "full" object with associations instead of the proxy classes in doctrine 2?

Because I'm serializing the entity (and relations) but when I deserialize I just get a proxy class back.

The query I'm doing:

public function getSnippet($id)
    {
        return $this->getEntityManager()->getRepository('GvnSnippetryBundle:Snippet')->findOneBy(array('id' => $id));
    }

J0HN's answer is good.

If you want to be more focused, you can force Doctrine to fetch-join the associated entities by creating a custom query (either directly in DQL, or using the QueryBuilder). To force the association to be loaded, you need both:

1) Join the associated entity 2) Reference that entity in the SELECT

So, in DQL:

SELECT f 
FROM Foo f
JOIN f.Bar b

This will not load the associated Bar, since it's not referenced in the SELECT -- you'll get a proxy instead, while

SELECT f, b
FROM Foo f
JOIN f.Bar b

will force doctrine to fetch-join your Bars.

Never tried that personally (and don't have Doctrine2 at fingertips), but marking association as EAGER should do the trick. Hovewer, you'll always load those associated object this way.

As a workaround, try accessing the associated entities before serializing. E.g. if you have followed the advice to encapsulate associated objects collection (and you really should follow it), you just access it with $snippet->howDidYouCallFunctionThatReturnCollection(). Doctrine intercepts the request to the Collection checks that it's filled with proxies and load it automatically. So, it should be something like:

class Snippet{
     //other declarations
    /** OneToMany(targetEntity='Blah', ...)*/
    protected $associations;

    public function getAssociations(){
        return $this->associations; //fills proxies with real data here
    }
}

public function getSnippet($id)
{
    $snippet = $this->getEntityManager()->getRepository('GvnSnippetryBundle:Snippet')->findOneBy(array('id' => $id));
    $snippet->getAssociations(); //gets only one association
    $snippet->getAssociations2(); //and so on
    return $snippet;
}

Note that it's no way a complete code sample, but I assume you know how to map associations. Anyway, review Working with Objects and Association Mapping chapters for more detailed description and code samples.
