how do display html + css tags in a rails helper method

Question

I am trying to write something like this, but it display me the whole string. Not the formatted "Today!". Feel free to tune my method :) thanks

def days_left(deadline)
  (if deadline.date-Date.today == 0
    "<strong>Today!</strong>"
  elsif deadline.date-Date.today < 1
    "<div class='expired'>Overdue</div>"
  else
    (deadline.date-Date.today).to_i
  end)
end

def days_left(deadline)
  (if deadline.date-Date.today == 0
    "<strong>Today!</strong>"
  elsif deadline.date-Date.today < 1
    "<div class='expired'>Overdue</div>"
  end).html_safe
end

Or, display it in the view with

<%= raw days_left(d) %>

it gives me 'undefined method `html_safe' for (138/1):Rational'

Replace .html_safe with .class and double-check that it's a String. Rails3 monkey-patches String and adds an html_safe attribute. You could also just try .to_s.html_safe because it appears your actual code is returning a Ruby Standard Library Rational class number and not a String.

I should note that the parens around the if..end are entirely optional, it's OK to just say end.html_safe if you like that better.
