Google Analytics with a fixed URL site - google-analytics

Question

I have a issue to track the user navigation in a site with FIXED URLs
No matter where the user is the URL will always be http://www.myurl.com
And so in my report the user stay always be at the on http://www.myurl.com
I would like to know if i can add something to the tracking script to improve the user tracking data
<!-- default google tacking code -->
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','https://www.google-analytics.com/analytics.js','ga');
ga('create', $cod, 'auto');
ga('send', 'pageview');
</script>
UPDATE
My solution:
Main page
<!-- default google tacking code -->
$this->response->insertScript($this->_minify("
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','https://www.google-analytics.com/analytics.js','ga');
ga('create', '" . $cod . "', 'auto');
ga('set', 'page', '" . $page . "');
ga('send', 'pageview');
"));
Forms, reports, windows
<!-- additional information -->
$this->response->insertScript($this->_minify("
ga('set', 'page', '" . $page . "');
ga('send', 'pageview');
"));

Answer 1

As I understand your site is a Single Page App so the URL does not change through the user's visit. The is a specific guide for SPA's here
All in all what you want to do is implement 'virtual' pageviews each time a user navigates to a new section of your site. You can set the 'page' attribute on the tracker and send a pageview using the command below
ga('set', 'page', '/new-page.html');
ga('send', 'pageview');

Answer 2

You can add a third parameter to the pageview call. This works as a virtual URL, i.e. the GA interface show it as a distinct URL in the reports despite the fact that it does not actually exist on the server. If you pass a distinct, meaningful value for every action of the user (or at least any action that changes the content enough to warrant a pageview) then you can tell what they've been up to.
ga('send', 'pageview', '/my/virtual/url/');
