Let's add the following to our RedisClient:
def get_all_messages(self): return [ { 'id': message_id, 'message': self.redis.get(message_id) } for message_id in self.redis.keys() ]
We start off by using self.redis.keys() to gather all keys that are stored in Redis, which, in our case, are the message IDs. We then have a list comprehension that will iterate through all of the message IDs and create a dictionary for each one, containing the message ID itself and the message that is stored in Redis, using self.redis.get(message_id).
