The way I have done this with DM in the past is like so: new_attributes = item. Attributes new_attributes. Delete(:id) Item.
Create(new_attributes) You can also do it in one line: Item. Create(item.attributes. Merge(:id => nil)).

Both DataMapper and ActiveRecord support ‘custom attributes’ of the type described (custom getters and setters is more accurate) – it’s all Ruby, after all. But that misses the point: conceptual coherence, declarative coding, responsibility decomposition, and more. The ActiveRecord team recognizes the value of the Property API: in ActiveRecord 3.1 the AR::Base.
Serialize method is enhanced to support custom serialization, one portion of the Property API: http://edgerails.info/articles/what-s-new-in-edge-rails/2011/03/09/custom-activerecord-attribute-serialization/index.html. However, the Property API provides far more than custom serialization. To understand it (coming from an ActiveRecord background), try to imagine a unified API covering the functionality currently fragmented between ActiveRecord’s inferred attributes (ie.
, every DB column is a converted into a primitively-typed attribute), AR::Base. Composed_of and AR::Base.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
