Question

I’m setting up a redis store where my session user_id values are stored in the cookie and the rest of the model data (first_name, last_name, username, etc…) are stored in redis. I’m very new to Redis and I’m not sure how to store the model data.

I have two questions:

1. What’s the best way to store it, should I serialize it in XML, JSON or a ruby object equivalent.

2. When the stored data is fetched, how can I transform that into a working model object? That way when I do user_fetched_from_redis.username then it would work like user_fetched_from_db.username. And if there are any fields that are not fetched from the redis store then I would want activerecord to do a SELECT * FROM statement to populate all the attributes in the object. Is this possible?
