[autotest] Serialize foreign key we don't want to follow
In some case, we don't want to follow a relationship when
serialize and de-serialize an object. However, we may
want to serialize the value of the foreign key value.
For example, we follow Host.hostattribute_set relationship to
serialize HostAttribute objects associated with a host. We
don't want to follow HostAttribute.host_id to go back to Host.
This CL allows a model to claim foreign keys that will be
serialized but will not be followed.
BUG=None
TEST=In python
>>> import common
>>> from autotest_lib.frontend import setup_django_environment
>>> from autotest_lib.frontend.afe import models
>>> models.HostAttribute.objects.filter(host_id=20)[0].serialize()
{'host_id': 20L, u'id': 203L, 'value': u'2271', 'attribute':
u'need_crash_log'}
>>> models.HostAttribute.deserialize({'host_id': 20L, u'id': 251L,
'value': u'2271', 'attribute': u'need_crash_log'})
<HostAttribute: HostAttribute object>
TEST=Test shard heartbeat works when host attributes present.
DEPLOY=apache, shard_client
