Rails string to DOB year

I'm currently storing strings formatted like "01/01/1989" (client side validation) for the bday field.

I want to parse out the year and store it as a variable, like this: 

@bdayyear = current_user.bday.year

I want that to bring back "1989"

How would I go about doing that?

If the format is always consistent the why not just use the string 

"01/01/1989".slice(-4..-1)
"01/01/1989"[-4..-1]

Or 

"01/01/1989".split(/\W/).pop

These will all return "1989" without converting it to a date

Convert it into a DateTime object and you can call year on it

>> DateTime.parse("01/01/1989").year
=> 1989

Just do using #strftime and ::strptime :

s = "01/01/1989"
current_user.bday.strptime(s, "%d/%m/%Y").strftime("%Y")
# => "1989"
