Question

I’m writing my first application in Ruby and I had a question.

Here is a sample:

 class SomeClass
    def initialize(host)
       @host = host
    end
end

How can I change the value of @host within another method? I have tried using
self.host = "somenewvalue" but that doesn’t work.

Answer 1

Use attr_accessor:

    class SomeClass
    attr_accessor :host
    def initialize(host)
       @host = host
    end
    end

or attr_reader and attr_writer to define methods host(getter) and host=(setter) separately.

UPD: got it wrong. You can access instance variables by adding @ in front of the variable name. So @host=”someothervalue” inside an instance method will work fine.
