    I've tryed Ajax on rails tutorial from http://www-128.ibm.com/developerworks/java/library/j-cb12056/?ca=dgr-lnxw02aAjaxOnRails

    so, first I've copied :
    <%= link_to_remote "time",
    :update => 'time_div',
    :url => {:action => "time"} %>

    literally, hoping that it would be picked up bu sintag, but i got "Click this link to show the current" without link "time" on the end.

    then I've chandged it into
    <?= $prototype_helper->link_to_remote('time',
    array('update' => 'time_div',
    'url' => array('action' => 'time'))) ?>

    with same result.

    the line <%= javascript_include_tag :defaults %> caused no code on output, so i've removed it.

    Hi Luka,

    Welcome to the Akelos forums,

    Seems like you have some configuration problem with your rewrite rules and Akelos

    For Ajax to work you certainly need the line

    <%= javascript_include_tag :defaults %>

    Which produces something like

    <script type="text/javascript" src="/javascripts/prototype.js">
</script>                           
<script type="text/javascript" src="/javascripts/event_selectors.js">
</script>                           
<script type="text/javascript" src="/javascripts/scriptaculous.js">
</script>
<script src="/javascripts/builder.js" type="text/javascript">
</script>    
<script src="/javascripts/effects.js" type="text/javascript">
</script>    
<script src="/javascripts/dragdrop.js" type="text/javascript">
</script>    
<script src="/javascripts/controls.js" type="text/javascript">
</script>    
<script src="/javascripts/slider.js" type="text/javascript">

    and I tried the code snippet

    <a onclick="new Ajax.Updater('time_div', '/blog/time/', {}); return false;" href="#">time</a>

    and worked as expected.

    Could you tell me which revision where you using?

    Hi!

    I've downloaded dev_preview week or so ago. version.txt says 0.7.1. I'm running it on Linux/apache2/php4.4.7. I've also tried

    <?= $asset_tag_helper->javascript_include_tag ('defaults') ?>

    with the same results. Most anoying thing is that there is no error, so i don't know where to start looking.


    If you are talking about rewrite as in mod_rewrite, 'public' is linked to ~/public_html/ajax and I've added

    RewriteBase /~uname/ajax

    into .htaccess

    P.S. I've forgot to mention, that non ajax version works fine. that is <%= link_to "time", :action => "time" %> works as expected

    Ive made same example in /var/www dir, and now it works ok. so it is something obaut rewriting I guess.
