Description

This is the error I get:

get_class() expects parameter 1 to be object, array given.

Stack Trace:

Please tell me how I can be more precise or of more help. Do you need my models for debugging? (I do not want to post them here).

I got the latest version from Github and this error still occures.

I also checked with my models. Before persisting my model with Doctrine all the referenced models are Documents. Somewhere in the Persister the model has to get changed to an array.

The issue seems to be in this http://github.com/doctrine/mongodb-odm/blob/master/lib/Doctrine/ODM/MongoDB/Persisters/BasicDocumentPersister.php#L419 method.

When calculating the changeset we end up with an array. When this array is passed on to prepareValue in http://github.com/doctrine/mongodb-odm/blob/master/lib/Doctrine/ODM/MongoDB/Persisters/BasicDocumentPersister.php#L464 this method can not handle the array.

I hope this helps a bit with pinpointing the error.

I changed the prepareReferencedDocValue method in BasicDocumentPersister.php to this:

private function prepareReferencedDocValue(array $referenceMapping, $document)
	{
		$id = null;

		if (is_array($document))
		{
			$className = $referenceMapping['targetDocument'];
		}
		else
		{
			$className = get_class($document);
			$id = $this->uow->getDocumentIdentifier($document);
		}

		$class = $this->dm->getClassMetadata($className);

		if (null !== $id)
		{
			$id = $class->getDatabaseIdentifierValue($id);
		}
		$ref = array(
				$this->cmd . 'ref' => $class->getCollection(),
				$this->cmd . 'id' => $id,
				$this->cmd . 'db' => $class->getDB()
		);
		if (!isset($referenceMapping['targetDocument']))
		{
			$discriminatorField = isset($referenceMapping['discriminatorField']) ? $referenceMapping['discriminatorField'] : '_doctrine_class_name';
			$discriminatorValue = isset($referenceMapping['discriminatorMap']) ? array_search($class->getName(), $referenceMapping['discriminatorMap']) : $class->getName();
			$ref[$discriminatorField] = $discriminatorValue;
		}
		return $ref;
	}

and this seems to solve the issue.

However, I was not able to get the whole Doctrine ODM unit testing set up, so I could not check if all unit tests still pass.

I would love if somebody could help me getting the github and unit testing environment for Doctrine set up, so that I can work on some issues too!
