Quote all fields in CSV output

Question

@out = File.open(\"#{File.expand_path(\"CSV\")}/#{file_name}.csv\", \"w\")
CSV::Writer.generate(@out) do |csv|
  csv << [\"01\", \"02\", \"test\"]
end
@out.clo         


        

Answer 1

Change

CSV::Writer.generate(@out)do |csv|

to

CSV::Writer.generate(@out, {:force_quotes=>true}) do |csv|

Answer 2

So why not double quote them?

@out = File.open("#{File.expand_path("CSV")}/#{file_name}.csv", "w")
CSV::Writer.generate(@out) do |csv|
  csv << ['"01"', '"02"', '"test"']
end
@out.close
