q.get_job_ids returns [] even if job just enqueued if using Redis database #1

[webquest-nz]

I had the following set up in my settings/base.py file.

RQ_QUEUES = {
    'default': {
        'HOST': 'localhost',
        'PORT': 6379,
        'DB': 1,
        #'USERNAME': 'some-user',
        #'PASSWORD': 'some-password',
        'DEFAULT_TIMEOUT': 360,
        #'REDIS_CLIENT_KWARGS': {    # Eventual additional Redis connection arguments
        #    'ssl_cert_reqs': None,
        #},
        'SSL_CERT_REQS':None,
    },
    'high': {
        'HOST': 'localhost',
        'PORT': 6379,
        'DB': 1,
    },
    'low': {
        'HOST': 'localhost',
        'PORT': 6379,
        'DB': 1,
    }
}

when running code similar to following I get a problem.

redis_conn = redis.StrictRedis(host='localhost', port='6379', db='1', password='')

q = django_rq.get_queue('default', connection=redis_conn)
job = q.enqueue( my_sample_function, job_id = 'my-job-id')
print (q.get_job_ids())
# returns [] instead of ['my-job-id']

The problem seems to go away if I change all references to "db='0'".

I was imagining that it shouldn't matter if db=1 or db=0. Am I missing something?
