Rails, Why does this helper not output HTML, but rather HTML in quotes?

I have the following helper in my application_helper.rb file:

  def topmenu
    pages = {
      "projects" => projects_path,
      "photos" => photos_path
    }
    pages.map do |key, value|
      classnames = %( class="current") if controller.controller_name == key
      "<li#{classnames}>#{link_to(key, value)}</li>"
    end
  end

Then in my application.html.erb file I have: 

<%= topmenu %>

For some reason, the page is generating showing the HTML from the above helper as TEXT, not HTML. Not sure why? thx

It makes the code more clean? Isn't it? And you can do more thing in the help function(because it is not only a html)

I presume you're running rails3. Add .html_safe method call before returning the string:

"<li#{classnames}>#{link_to(key, value)}</li>".html_safe
