  1. POflash reappears on refresh
    text
    copied!<p>I show flash messages in my rails app using javascript (essentially every flash message is an overlay div).</p> <p>The following partial is included in my main layout file and it takes care of displaying the flash. I notice that if I refresh a page, the same flash message keeps reappearing. Anyway to get rid of this? I know I can call a flash.discard though not sure what's the best place to do that and I don't want another controller call just to discard the flash.</p> <pre><code>&lt;% if !flash.nil? %&gt; &lt;% if flash[:notice] %&gt; &lt;script type="text/javascript"&gt; //&lt;![CDATA[ showFlash("&lt;%= flash[:notice] %&gt;", "flash-notice"); //]]&gt; &lt;/script&gt; &lt;% end %&gt; &lt;% if flash[:success] %&gt; &lt;script type="text/javascript"&gt; //&lt;![CDATA[ showFlash("&lt;%= flash[:success] %&gt;", "flash-success"); //]]&gt; &lt;/script&gt; &lt;% end %&gt; &lt;% if flash[:error] %&gt; &lt;script type="text/javascript"&gt; //&lt;![CDATA[ showFlash("&lt;%= flash[:error] %&gt;", "flash-error"); //]]&gt; &lt;/script&gt; &lt;% end %&gt; &lt;% end %&gt; function showFlash(msg, tp) { if ($('#flash_messages_container').length &gt; 0) { flashAnimatedHide(); } var flashContainer = $("&lt;div id='flash_messages_container' class='flash-messages " + tp + " '&gt;&lt;/div&gt;"); flashContainer.prepend("&lt;div id='flash_messages_content'&gt;" + msg + "&lt;span class='go-right sprite close' id='close_flash'&gt;&lt;/span&gt;&lt;/div&gt;"); $('body').prepend(flashContainer); flashContainer.animate({ opacity : .1 }, '500', function(){ flashContainer.css('opacity', 1) }) $('body').css('margin-top', flashContainer.outerHeight()); $('#close_flash').click(function() { flashAnimatedHide(); $('body').css('margin-top', '0'); }); } </code></pre> <p>UPDATE</p> <p>I suspect this is happening since I starting using etags for cient side and reverse proxy caching. So I guess the refresh is simply loading the cached page, which contains the flash messages in the flash container. So how do people discard flash when caching is enabled?</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
