title: Rails 4: Creating point rules using merit gem
body: <p>I am in the process of converting my app's voting and reputation system from <a href="https://github.com/twitter/activerecord-reputation-system" rel="nofollow">activerecord-reputation-system</a> to <a href="https://github.com/tute/merit" rel="nofollow">merit</a> because the latter seems to have a much more active core team.</p>
  
  <p>I'm attempting to establish point rules for voting on questions and answers in my app. Ideally, when a user votes up a question, the rule would allocate points to the question itself, and also to the question's creator.</p>
  
  <p>From merit's readme section on <a href="https://github.com/tute/merit#defining-point-rules" rel="nofollow">point rules</a>, I see this example:</p>
  
  <pre><code>score 15, on: 'reviews#create', to: [:reviewer, :reviewed]
  </code></pre>
  
  <p>My understanding is that <code>:reviewer</code> and <code>reviewed</code> in this example are the ones that get the points allocated to them. However, when I try this in my own point_rules.rb:</p>
  
  <pre><code>score 10, :on =&gt; 'questions#vote', :to =&gt; :question 
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>[merit] NoMethodError on `Question#question` (called from Merit::TargetFinder#other_target)
  </code></pre>
  
  <p>I know that I am missing something here, but can someone please tell me what it is?</p>
