Rails button_to helper using a button tag rather than an input tag

gistfile1.rb

def button_to_with_button_element(name, options = {}, html_options = {})
  fragment = ::Nokogiri::HTML.fragment(button_to(name, options, html_options))
  fragment.css("input[type=submit]").each do |input|
    input.replace ::Nokogiri::HTML.fragment("<button class='#{input.attribute("class")} type='submit'>#{input.attribute("value")}</button>")
  end
  raw fragment.to_html
end

You'll need to add gem 'nokogiri' to your Gemfile.
