Rails optional argument

Question

I have a class

class Person
    attr_accessor :name,:age
    def initialize(name,age)
        @name = name
        @age = age
    end
end

Answer 1

If you want both arguments to be optional but also set default values when nil then you could go with:

class Person

def initialize(name = nil, age = 0)
  @name ||= "Default name"
  @age = age
end

end

This gets over the issue of passing nil as the first option but still getting a useable default value.

@person = Person.new nil, 30
@person.name # => "Default name"
@person.age # => 30
