This is a real ultra newbie question.
I have an age stored in a database.
When I get the age from the database I want to get each individual digit.
Example:
User.age = 25
I want to get the following:
first = 5
second = 2
I can't seem to wrestle this from the data as its a fix num.
Anyone know a clean and simple solution.
You can convert to a string and then split into digits e.g.
first, second = User.age.to_s.split('')
=> ["2", "5"]
If you need the individual digits back as Fixnums you can map them back e.g.
first, second = User.age.to_s.split('').map { |digit| digit.to_i }
=> [2, 5]
Alternatively, you can use integer division e.g.
first, second = User.age.div(10), User.age % 10
=> [2, 5]
Note that the above examples are using parallel assignment that you might not have come across yet if you're new to Ruby.
