FasterCSV - instead of getting the content file getting the path to file
===

      def csv_parsing
        require 'csv'
        csv_file_path = File.join(File.dirname(__FILE__), "csv_data.csv")
        CSV.parse(csv_file_path) do |line|
          puts line[0]
        end
      end

This is a simple example, how I try to parse CSV file. The action above is placed in controller, the file is in the project's root.

But instead of getting the data from CSV file I am getting the path to file, like:

    /Users/my_mane/ruby_folder/my_project/app/controllers/csv_data.csv

Note: the file contain a real data.

Why is printed out instead of own data just the file path?
