does not work with rails 2.3

[xain]

I got Argument 1 for 0 (sum method) error with rails 2.3.

Have to modified / lib / indicators / calculations / helper.rb
sum method to:

  unless method_defined?(:sum)
    # Compute the sum of the values of an Array.
    def sum
      return self.inject(0){|accum, i| accum + i }
    end
  end

Is there a specific reason why you are using rails 2.3? you are looking for trouble :)

It is a legacy app. It's too old to be rewritten.

But the problem has been solved.It just need Exponental Moving Average method of this gem. I wrote a simple version for that app. So no more need this gem now. :)
