title: Rails session still alive after db:drop
body: <p>I'm curious  why <code>session</code> left alive after <code>rake db:drop</code>?</p>
  
  <p>I have </p>
  
  <pre><code>  def current_order
      if !session[:order_id].nil?
       @current_order =  Order.find(session[:order_id])
      else
        Order.new
      end
    end
    helper_method :current_order
  </code></pre>
  
  <p>and after rake db:drop it gives me exception </p>
  
  <pre><code>Couldn't find Order with 'id' = my session number
  &gt;&gt; session[:order_id]
  =&gt; 11
  </code></pre>
  
  <p>that means session still there. But Why?</p>
