Rails console vs a rake task: returning File.size is not consistent

Question

I'm having a strange issue where when I check the File.size of a particular file in Rails console, it returns the correct size. However when I run the same code in a rake task, it returns 0. Here is the code in question (I've tidied it up a bit to help with readability):

def sum_close
  daily_closed_tickets = Fst.sum_retrieve_closed_tickets
  daily_closed_tickets.each do |ticket|
      CSV.open("FILE_NAME_HERE", "w+", {force_quotes: false}) do |csv|
          if (FileCopyReceipt.exists?(path: "#{ticket.attributes['TroubleTicketNumber']}_sum.txt")) 
              csv << ["GENERATE CSV WITH ATTRIBUTES HERE"]
              files = Dir.glob("/var/www/html/harmonize/public/close/CLOSED_#{ticket.attributes['TroubleTicketNumber']}_sum.txt")
              files.each do |f|
                  Rails.logger.info "File size (should return non-0): #{File.size(f)}" #returns 0, but not in Rails Console
                  Rails.logger.info "File size true or false, should be true: #{File.size(f) != 0}" #returns false, should return true
                  Rails.logger.info "Rails Environment: #{Rails.env}" #returns production
                  if(!FileCopyReceipt.exists?(path: f) && (File.size(f) != 0))
                      Rails.logger.info("SUM CLOSE, GOOD => FileUtils.cp_r occurred and FileCopyReceipt object created")            
                  else
                      Rails.logger.info("SUM CLOSE, WARNING: => no data transfer occurred")
                  end
              end
          else
              Rails.logger.info("SUM CLOSE => DID NOT make it into initial if ClosedDate.present? if block")
          end
      end
  end

close_tickets.rake

task :close_tickets => :environment do
    tickets = FstController.new
    tickets.sum_close
    tickets.dais_close
end

It is beyond me why this File.size comes back as 0 when this is run as a rake task. I thought it may be a environment issue, but that does not seem to be the case.

Any insight on the matter is appreciated.

Answer 1

The CSV.open block and everything being wrapped in there was causing issues. So I just made CSV generation it's own snippet instead of wrapping everything in there.

daily_closed_tickets.each do |ticket|
    CSV.open("generate csv here.txt") do |csv|
        #enter ticket.attributes here for the csv
    end
    #continue on with the rest of the code and File.size() works properly
end
