How to split a string in Ruby and get all items except the first one?
Try this:
first, *rest = ex.split(/, /)
Now first will be the first value, rest will be the rest of the array.
ex.split(',', 2).last
The 2 at the end says: split into 2 pieces, not more.
normally split will cut the value into as many pieces as it can, using a second value you can limit how many pieces you will get. Using ex.split(',', 2) will give you:
["test1", "test2, test3, test4, test5"]
as an array, instead of:
["test1", "test2", "test3", "test4", "test5"]
