For the life of me, i cant figure out why this problem is happening. I used the link_to helper all the time, but iv only used the link_to_if helper a few times, and this time I cant get the link to take a CSS class.

Here's my link

<%= link_to_if(step.sequence > 1, raw('<i class="icon-chevron-up"></i>'), url_for(:controller => :test_steps, :action => :update_sequence, :direction => 'up', :id => step.id, :test_script_id => @test_script), { :class => 'btn btn-mini' })%>

The image displays, with no link as expected, but the CSS class defined at the end does not, instead it just has no class. This is the same format I use in all my link_to helpers.

Can anyone explain why?

Using link_to_if, only the name --in your case the result of raw('<i class="icon-chevron-up"></i>')-- will be returned if the condition fails. All options that would otherwise apply to the link tag will be ignored.

See the source.

Try passing an empty hash as the options argument, so that { :class => '...' } is assigned to the html_options argument. Untested

<%= link_to_if(step.sequence > 1, raw('<i class="icon-chevron-up"></i>'), url_for(:controller => :test_steps, :action => :update_sequence, :direction => 'up', :id => step.id, :test_script_id => @test_script), {}, { :class => 'btn btn-mini' })%>

Wrap the link_to_if or link_to_unless in a span:

 %span.pull-right
   = link_to_unless Foo.deleted.empty?, "<i class='icon-white icon-trash'></i> Undelete Foo".html_safe, deleted_foos_path

Above code sets a css class (pull-right) on whatever is displayed - full link or just its text.
