Require csv in rails app?

Question

I have the following in my controller:

  private
  def csv_to_array(file)
    csv = CSV::parse(File.open(file, 'r') {|f| f.read })
    fields = csv.shift
    csv.collect { |record| Hash[*fields.zip(record).flatten ] }
  end

And it throws this issue:

NameError (uninitialized constant FController::CSV):
  app/controllers/f_controller.rb:27:in `csv_to_array'
  app/controllers/f_controller.rb:9:in `import'

It's my understanding that csv is included by default in the ruby toolkit, thus not needing to be required. What's causing this issue?

Answer 1

It is in the standard library, but you still have to require it:

require 'csv'

This is one of the differences betweeen core and std-lib.
