Subject: Re: Calling class method from instance method

Ryan Davis ,
"When you want to have a class call an "instance method", which instance
would call it?"

Good point! Makes sense.

Anurag Priyam, this is pretty wierd... but works.

You see, there's stuff that need to be donne in both cases, in instances
and in classes. For example:

class SomeClass
  def self.method
    if file_exists?
      #do stuff
    end
    #something need to be donne here, and I need to check if the file
exists
    #I dont want to define a nother class method exactly the same as the
already declared instance method.
  end

  def file_exists?
    #there are instance methods depending on this one
    File.exists?("some_file_name.txt")
  end
end

How do you deal with this kind of thing?
