Creating our Message Service

In our service.py, we can now make use of our new Redis Dependency Provider. Let's start off by creating a new service, which will replace our Konnichiwa Service from earlier. First, we need to update our imports at the top of our file:

from .dependencies.redis import MessageStore 

Now we can create our new service:

class MessageService: 
 
    name = 'message_service' 
    message_store = MessageStore() 
 
    @rpc 
    def get_message(self, message_id): 
        return self.message_store.get_message(message_id) 

This is similar to our earlier services; however, this time we are specifying a new class attribute, message_store. Our RPC entrypoint, get_message, can now make use of this and call get_message in our RedisClient and simply return ...
