Select a random node on every reload

I want to select a random node on every reload. My fusion file looks like this:

randomInt = ${Math.randomInt(0, q(node).children(Neos.Neos:Document).count()}
randomNode = ${q(node).children(Neos.Neos:Document).get(this.randomInt)}

Unfortunately the result is stored in the cache. That means that only after the cache get flushed a new node will be returned. How can I prevent this? I have already experimented with the cache rules a little bit, but I didn't come up with a solution yet.

Solution

  • The element that I want to use is on every page. That's why something like the unchached mode would be a really bad idea.

    In my situation the output is only a array of strings. So I did following in my Fusion.

    1. Generate "almost" a Array in Fusion

      allMyStrings = Neos.Fusion:Loop {
    items = ${q(node).children(Neos.Neos:Document).get()}
    itemName = 'node'
    itemRenderer = ${"'" + q(node).property('testString') + "'"}
    @glue = ','
}

    2. Pick a random array in JS

      <p id='replaceMe'></p>
<script>
  var quoteArray = [{allMyStrings -> f:format.raw()}]
  var randomIndex = Math.floor(Math.random() * quoteArray.length);
  var randomElement = quoteArray[randomIndex];
  document.getElementById('replaceMe').outerHTML= '<p>' + randomElement + '</p>';
</script>

    A bit hacky but it works and it don't harm the performance of the website
