Question

I have the following code in a Rails 3.2.1 helper that keeps escaping HTML even if i don’t want it, and i can’t figure out how to turn off the html escaping on this method (calling raw or html_safe doesn’t work):

module OffersHelper
  def price_tag(amount)
    amount = amount.to_f
    floor = amount.floor
    cents = ((amount - amount.floor) * 100).to_i
    content_tag(:h2) do
      html = floor.to_s
      html << content_tag(:sup, cents) if cents > 0
      html
    end
  end
end

If i remove the nested content_tag (the sup tag), the html escaping is turned off…

Answer 1

Try:

module OffersHelper
  def price_tag(amount)
    amount = amount.to_f
    floor = amount.floor
    cents = ((amount - amount.floor) * 100).to_i
    out = content_tag(:h2) do
      html = floor.to_s
      html << content_tag(:sup, cents) if cents > 0
      html
    end
    out.html_safe
  end
end
