Question

In my app, I have a textfield in which the user enters something like this

"1,2,3,4"

which gets stored to the database. Now, when I want to use the inner numbers, i have two options:

"1,2,3,4".split(',')

OR

string.scan(/\d+/) do |x|
    a << x
end

Both ways i get an array like

 ["1","2","3","4"] 

and then i can use the numbers by calling to_i on each one of them.
Is there a better way of doing this, that converts

"1,2,3" to [1,2,3] and not ["1","2","3"]

Answer 1

str.split(",").map {|i| i.to_i}

but the idea is same to you….
