yaml serialization to file fails

[antony_hatchkins]

When serializing anything to yaml with stream=open('file','w') it fails with the following error:

XMLSerializer = serializers.get_serializer('yaml')
serializer = XMLSerializer()
serializer.serialize(Partner.objects.all(), stream=open('partners.yaml', 'w'))

Traceback (most recent call last):

File "./bin/serialization/serialize_partners.py", line 16, in <module>

serializer.serialize(Partner.objects.all(), stream=out)

File "/var/django/phones-lev/django/core/serializers/base.py", line 56, in serialize

return self.getvalue()

File "./django/core/serializers/pyyaml.py", line 43, in getvalue

return self.stream.getvalue()

AttributeError: 'file' object has no attribute 'getvalue'
