Resque require 'csv' not working - ruby-on-rails

Question

I am using resque to process a file in the background. It's a CSV file however I get the following error: uninitialized constant ImportFileHelper::CSV
I have tried to require 'csv' and also include CSV neither will work.
require 'csv'
module ImportFileHelper
HOST = ""
USER_NAME = ""
PASSWORD = ""
def self.process_file(file_data, file_name)
init
#file_name = file_name
begin
csv = CSV.parse(file_data, :headers => true)
csv.each do |row|
#first_name = row["FirstName"]
#last_name = row["LastName"]
#email = row["Email"]
#password = "ch#ngeM3!"
#user_group_name = row["GroupName"].split(",")
#store_name = row["StoreName"]
#external_id = row["ExternalID"]
add_user unless #first_name.nil? || #last_name.nil? || #email.nil? || #password.nil? || #first_name.empty? || #last_name.empty? || #email.empty?

end
end
So as a work around for this I am doing the csv parsing in the resque job file. This is now allowing it to run. Not sure if this is the best way to do it though.
class ProcessFile
#queue = :rts_file_parser
def self.perform(file_data, file_name)
csv = CSV.parse(file_data, :headers => true)
csv.each do |row|
row_data = { first_name: row["FirstName"], last_name: row["LastName"], email: row["Email"], password: "ch#ngeM3!", user_group_name: row["GroupName"].split(","), store_name: row["StoreName"], external_id: row["ExternalID"] }
ImportFileHelper.process_file file_name, row_data
end
end
end

Answer 1

Mind if I claim the answer (via my comment)?
It looks like it might be a scope resolution issue.
Try ::CSV instead of CSV.

Answer 2

Try adding the gem to the gemfile.
