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

推荐答案

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

或者，使用

<%= raw days_left(d) %>
