Addin lines to existing csv file with fastercsv

I’am trying to add new lines to a existing csv file, but i only get one
line.
It doesn’t add additional lines, i pasted te code below, has anyone a
suggestion how to write new lines?

require ‘fastercsv’

FasterCSV.open(“d:/file.csv”, “w”) do |csv|
csv << [@params[:ha_gewas2], “first name”, “last name”, “email”]
end

It doesn’t add additional lines, i pasted te code below, has anyone a
suggestion how to write new lines?
You need to insert newlines after each record string.

For example:
       hdr = [['field1a', 'field1b'], 'field2', 'field3',

‘field4’].flatten.join(’,’)
FasterCSV.open(“my_csv_file.csv”, “w”) {|file|
file << hdr + “\n” # There’s a different newline
thingamajigger for Windows: \r\n
# proceed with adding additional records here.
}

Open using “a” instead of “w” to append to the file. See “ri IO” for a
list
of file modes.
