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

-

i have following helper in application_helper.rb file:

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

then in application.html.erb file have: 

<%= topmenu %>

for reason, page generating showing html above helper text, not html. not sure why? thx

i presume you're running rails3. add .html_safe method call before returning string:

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