Question

In Java I might do:

public static void doSomething();

And then I can access the method statically without making an instance:

className.doSomething(); 

How can I do that in Ruby? this is my class and from my understanding self. makes the method static:

class Ask

  def self.make_permalink(phrase)
    phrase.strip.downcase.gsub! /\ +/, '-'
  end

end

But when i try to call:

Ask.make_permalink("make a slug out of this line")

I get:

undefined method `make_permalink' for Ask:Class

Why is that if i haven’t declared the method to be private?

Answer 1

Your given example is working very well

class Ask
  def self.make_permalink(phrase)
    phrase.strip.downcase.gsub! /\ +/, '-'
  end
end

Ask.make_permalink("make a slug out of this line")

I tried in 1.8.7 and also in 1.9.3
Do you have a typo in you original script?

All the best
