Subject: Re: Fill gaps in Array of Hashes

Yep, i understand, but it returns wrong value (and not sorted by date 
;-():

    ("2009-11-11".to_date.."2010-01-01".to_date).each do |date|
      exists = result.find { |x| x[:date] == date.to_s }
      next if exists
      result << { :positive => "0", :neutral => "0", :total => "0", 
:date => date, :negative => "0" }
    end

    return result

=> [{:positive=>"0", :neutral=>"2", :total=>"5", :date=>"2009-12-01",
