How to split a string in Ruby and get all items except the first one?
ex.split(',', 2).lastThe 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"]
Since you've got an array, what you really want is Array#slice, not split.
rest = ex.slice(1 .. -1)# orrest = ex[1 .. -1]
