Rails vanity gem custom metric error: private method `to_time' called

Question

Hi I am trying to setup Vanity gem into a rail 3 application. I am creating a custom metric to experiment a bit.

So I created it following the suggestions on their website:

metric "Signups" do
  description "Signups completed"
  def values(from, to)
    (from..to).map { |i| 24 }
  end
end

The file is located at the right place and is loaded, vanity picks it up but somehow it looks like there is an internal error in the way vanity works.
Of course: those values are only there for a testing purpose, they will be replaced by real ones later.

I get the following error when running this experiment

Thank you!

There seems to be an error in the gem:

in this file .rvm/gems/ruby-1.9.2-p290/gems/vanity-1.7.1/lib/vanity/templates/_metric.erb

where we can read the following line

js = data.map { |date,value| "['#{**date.to_time.httpdate**}',#{value}]" }.join(",")
  vanity_html_safe(%{<div class="chart"></div>

if we change date.to_time.httpdate to date.to_s.to_time.httpdate it works.
