Topic: redis, active record

hi,
i've implemented a feed and im storing all all the data within redis

#redis key
#{"car_id":3,"user_id":6, "created_at":"2012-08-01T11:29:55+02:00"}

in the view im looping over the keys. whats best practice to get additional model data. i only have the car id but need to query
the car model for the rest. i probably shouldn't do this in the view?

CONTROLLER

@feed = $redis.zrevrangebyscore "feed:#{current_user.id}", Time.now.to_i, 0

VIEW

@feed.each do |item|
 data =ActiveSupport::JSON.decode(item) 
 car_id = data["car_id"]

 car = Car.find(car_id)
end

thanks

pete
