title: NameError: uninitialized constant -- activerecord
body: <p>I have two classes, Number and Freebie:</p>
  
  <pre><code>class Number &lt; ActiveRecord::Base
    belongs_to :account
    has_many :freebies
  
  end
  
  class Freebie &lt; ActiveRecord::Base
    belongs_to :number
  
    attr_accessible :name, :data
  
    has_attached_file :data, :path =&gt; "freebies/:id_partition/:filename"
  
    def to_s
      name
    end
  end
  </code></pre>
  
  <p>All of my other classes with a has_many and belongs_to relationship work fine, but when I call something like:</p>
  
  <pre><code>n = Number.last
  n.freebies.create
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>NameError: uninitialized constant Number::Freeby

  <p>I've had some other problems with the Freebie class because it ends with ie and Rails tries to make the singular version "Freeby" instead of Freebie. Still, I'm not sure why this isn't working.</p>
