Hi Gang:
The CSV package provides several different methods to read and parse CSV files
and I use several of the options in my application without any problems. The
CSV.open method returns an instance of CSV as the error indicates. You invoke
the shift method on a CSV instance to parse a line from the file and return the
result in an Array or invoke the left shift method "<<" to encode a line when
writing. Try the following:
CSV.open('save.csv', 'r') do | csv |
row = csv.shift
puts row.inspect
end
CSV.open('save.csv', 'wb') do | csv |
csv << [ "Append this row", "Hi" ]
end
