title: Rails 4 Active Record Joins and Includes not working
body: <p>I have two models: Place and Subfilter</p>
  
  <pre><code>class Place &lt; ActiveRecord::Base
    belongs_to :subfilter
  end
  
  class Subfilter &lt; ActiveRecord::Base
    has_many :places
  end
  </code></pre>
  
  <p>The following two queries return the same value as <code>Place.all</code></p>
  
  <ol>
  <li><code>Place.joins(:subfilter)</code></li>
  <li><code>Place.includes(:subfilter)</code></li>
  </ol>
