[Rails] Re: Get the class name of the class who called the parent instance method.

Ruby on Rails Friday, October 10, 2014

You might want something like this.



class Foo
end

Foo.instance_eval do
  def class_name
    self.name
  end
end


class Bar < Foo
end

class Tar < Foo
end

puts Foo.class_name
#=> Foo

puts Bar.class_name
#=> Bar

puts Tar.class_name
#=> Tar

Is there a way for me to do that on ruby ?

class Foo
  def self.class_name
  end
end

class Bar < Foo
end

class Tar < Foo
end

Bar.class_name 
= 'Bar'

Tar.class_name
= 'Tar'

I want to get the class name of the class who called the instance method from the parent class.

I tried the code above and it keeps getting me 'Class' as the result.

Is that possible in ruby ?
