title: Undefined method `roles'?
body: <p>I'm having issues seeding my database with the default roles of my users.</p>
  
  <pre><code>class User &lt; ActiveRecord::Base
    attr_accessible :email, :password, :password_confirmation, :remember_me, :username
    devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable
    validates_presence_of :username, :email, :password, :password_confirmation
    validates_uniqueness_of :username, :email
  
    before_create :setup_default_role_for_new_users
  
    ROLES = %w[admin default]
  
    private
  
    def setup_default_role_for_new_users
      self.roles = [ "default" ]
    end
  end
  </code></pre>
  
  <p><strong>Seeds.rb</strong></p>
  
  <pre><code>puts 'Loading seed data now....'
  user1 = User.create(:username =&gt; 'admin',   :email =&gt; 'testing@email.com', :password =&gt; 'qweasd',:password_confirmation =&gt; 'qweasd', :role =&gt; 'admin')
  user2 = User.create(:username =&gt; 'userone', :email =&gt; 'user1@email.com', :password =&gt; 'qweasd', :password_confirmation =&gt; 'qweasd')
  user3 = User.create(:username =&gt; 'usertwo', :email =&gt; 'user2@email.com', :password =&gt; 'qweasd',:password_confirmation =&gt; 'qweasd')
  puts 'Users added'
  </code></pre>
  
  <p>When seeding the error I get:</p>
  
  <pre><code>undefined method `roles' for #&lt;User:0x53f4c60&gt;
  </code></pre>
  
  <p>I have have the <code>role</code> column in my database so why wouldn't it work?</p>
