Heroku file upload problem

Question

I\'ve been having a problem uploading a CSV file to Heroku and processing it. It works fine in my local environment. Just do be clear, I don\'t need to save the file on Hero

Answer 1

I am still suck with this problem. I tried the solution given here to be able to do a csv file upload and then parse it to fill my DB through acive record. I have the following code:

file = IO.read(params[:file].tempfile.path)
    FasterCSV.new(file, :headers => true).each do |row|
         # my parsing logic
    end

The code just works perfect in the local but does not work at all in Heruko. I get error and all that I could see in the heruko logs is this:

I am sure it has something to do with the ruby version. I am using ruby 1.8.7 locally and its a rails 3 application. I am not sure what ruby version is there on heruko. But I can tell that I am using ceder stack.
