CSV Export error

Hi guys, When I export data into a .csv file, it works perfectly. when I push the code to heroku, I get the following error: ActionView::Template::Error (can't convert Hash into String):

My helper to generate the csv is: def generate_csv    csv_str = CSV.generate(:col_sep => ",") do |csv|       Entrant.find(:all).each do |entrant|         csv << [entrant.firstname, entrant.lastname, entrant.email, entrant.entrydate]       end     end   end

Is there any reason why I would get this error?

Thanks in advance for your help.

Are you running the same ruby version locally and in production ? This looks like it might be a ruby 1.8 vs 1.9 thing (the csv library was rewritten for 1.9)
