Use the split method to do it:
使用分割方法:
"one,two,three,four".split(',')
# ["one","two","three","four"]
If you want to ignore leading / trailing whitespace use:
如果您想忽略前导/后导空白，请使用:
"one , two , three , four".split(/\s*,\s*/)
# ["one", "two", "three", "four"]
If you want to parse multiple lines (i.e. a CSV file) into separate arrays:
如果您希望将多行(即CSV文件)解析为单独的数组:
require "csv"
CSV.parse("one,two\nthree,four")
# [["one","two"],["three","four"]]

require 'csv'
CSV.parse_line('one,two,three,four') #=> ["one", "two", "three", "four"]
