title: Getting multiple key values from Redis
body: <p>I'm currently playing around with Redis and i've got a few questions. Is it possible to get values from an array of keys?</p>
  
  <p>Example:</p>
  
  <pre><code>users:1:name "daniel"
  users:1:age  "24"
  
  users:2:name "user2"
  users:2:age  "24"
  
  events:1:attendees "users:1", "users:2"
  </code></pre>
  
  <p>When i <code>redis.get events:1:attendees</code> it returns <code>"users:1", "users:2"</code>. I can loop through this list and get users:1, get users:2. But this feels wrong, is there a way to get all the attendees info on 1 get?!</p>
  
  <p>In rails i would do something like this:</p>
  
  <pre><code>@event.attendees.each do |att|
    att.name
  end
  </code></pre>
  
  <p>But in redis i can't because it returns the keys and not the actual object stored at that key.</p>
  
  <p>thanks :)</p>
