Pymongo implementation as described here: http://cookbook.mongodb.org/patterns/random-attribute/ Note that you need to have the field 'random' indexed in mongo: http://api.mongodb.org/python/current/api/pymongo/collection.html#pymongo.collection.Collection.ensure_index Could be extended to use other formal parameters from find: http://api.mongod…

mongo_random.py

def get_random(collection, query={}):
    '''Gets a random record from a mongo collection'''
    random_num = random.random()
    query.update({'random' : {'$gte' : random_num}})
    result = collection.find_one(query)
    if not result:
        query.update({'random' : {'$lt' : random_num}})
        result = collection.find_one(query)
    return result
