What you have to do is:

class Person
  # you can define
  public
  # , but stuff is public by default when it hasn't been specified yet.

  belongs_to(bla)
  validates_presence_of(hohoho)

  protected

  attr_reader(:genre)

  # As example; validate needs to be protected.  
  def validate

  end

  private

  def private_method

  end
end
