Rails ApplicationHelper Escaping HTML without a return statement

Question

When I write

module ApplicationHelper def flash_helper flash.each do |key, msg| content_tag :div, msg, :class => key ## "<div class=\"key\">" + msg + "</div>" end end end 

I get nothing if not I return . When I call <%= flash_helper %> , the HTML is hiding in my view. What gives? How can I prevent HTML escaping?

Answer 1

You can use the concat method (Rails> = 2.2.1)

 module ApplicationHelper def flash_helper flash.each do |key, msg| concat(content_tag :div, msg, :class => key) end nil end end 

Answer 2

can you rewrite it like this?

 module ApplicationHelper def flash_helper s = "" flash.each do |key, msg| s += content_tag :div, msg, :class => key ## "<div class=\"key\">" + msg + "</div>" end return s end end
