Getting a reference to an object's parent... possible?

[markrickert]

Hey there, I'm using Dish in RubyMotion and I really love it! Thanks so much for creating this library and making it compatible with RM!

Question about getting a reference to an object's parent...

I have:

{
  id: 12,
  items: [{
    name: "test1"
  },{
    name: "test2"
  }]
}

Defined by:

class Order < Dish::Plate
  coerce :items, Item
end
class Item < Dish::Plate
end

Is there a way to get an item's parent (Order) id?

# my_item is an Item
my_item.parent # Order object
my_item.parent.id # 12

Or if not, is there perhaps a way to set a weakref to the parent when initializing the objects?

class Order < Dish::Plate
  # Something like this?
  coerce :items, ->(value) { Item.new(value, self) }
end
class Item < Dish::Plate
  def initialize(hash, parent)
    super
    @parent = WeafRef.new(parent)
  end
end

Any ideas? Thanks again for the great library!

It's not possible right now, but I'll keep it in mind. Think it's a good idea. Thanks.
