Inheritance and private vs protected

private.rb

class Parent
  def initialize(name)
    @name = name
  end
  
  private
  
  attr_accessor :name
end

class Child < Parent
  def parents_name(parent)
    parent.name
  end
end

bob = Parent.new("Bob")
betty = Child.new
betty.parents_name(bob)
#=> NoMethodError: private method `name' called for #<Parent:0x007fbf240a2770 @name="Bob>

protected.rb

class Parent
  def initialize(name)
    @name = name
  end
  
  protected
  
  attr_accessor :name
end

class Child < Parent
  def parents_name(parent)
    parent.name
  end
end

bob = Parent.new("Bob")
betty = Child.new
betty.parents_name(bob)
#=> "Bob"

I see. This has nothing to do with inheritance, you can demonstrate the same problem without a child class.

@sgrif How would you go about doing that?
