title: Rails: Easy way to add more than one flash[:notice] at a time
body: <p>I thought every time you do a <code>flash[:notice]="Message"</code> it would add it to the array which would then get displayed during the view but the following just keeps the last flash:</p>
  
  <pre><code>flash[:notice] = "Message 1"
  flash[:notice] = "Message 2"
  </code></pre>
  
  <p>Now I realize it's just a simple hash with a key (I think :)) but is there a better way to do multiple flashes than the following:</p>
  
  <pre><code>flash[:notice] = "Message 1&lt;br /&gt;"
  flash[:notice] &lt;&lt; "Message 2"
  </code></pre>
