I have a string
"1,2,3,4"
and I'd like to convert it into an array:
[1,2,3,4]
How?
+4
A:
"1,2,3,4".split(",") as strings
"1,2,3,4".split(",").map { |s| s.to_i } as integers

+11
A:
>> "1,2,3,4".split(",")
=> ["1", "2", "3", "4"]
Or for integers:
>> "1,2,3,4".split(",").map { |s| s.to_i }
=> [1, 2, 3, 4]

Remember, if you're using >=1.9, you can just use "1,2,3,4".split(',').map(:to_i)
