    Hi. I would like to pass class name for link via ruby-like syntax link_to('Foo', :controller=>'bar', :action=>'test', :class=>'current') But this snippet don't works (pass class as part of route). So, first question is how to pass class name to link. Second is, how to pass class name, only for "current" link( curent is link to action, which is actual rendered)

    kkrzyzak, the expected behaviour of the Sintags you mention is

    http://example.com/bar/test/?class=current

    Could you clarify your question?

    well- I would like to have &lt;a href="http://example.com/bar/test" class="current">Foo&lt;/a> - that's my first question. Second is, how to add class="current" only if rendered action equals :action from link_to function

    Oops! I misread, the output I mentioned is for url_for. Sorry.

    In order to get the link with the class attribute, :class => 'current' needs to be the last parameter in the helper.

    <%= link_to( 'Foo', {:controller=>'bar', :action=>'test'}, {:class=>'current'}) %>

    or

    <%= link_to 'Foo', {:controller=>'bar', :action=>'test'}, :class=>'current' %>

    To condition the class you'll need to code a helper function like

    function link_to_action($name, $url_options, $html_options)
{
    if($this->_controller->getActionName() == AkInflector::underscore($name)){
        $html_options['class'] = empty($html_options['class']) ? 'current' : $html_options['class'].' current';
    }
    $this->_controller->url_helper->link_to($this->t($name), $url_options, $html_options);
}

    which you can insert into a layout helper and include it on you application controller.
