My alternative to the DCI principle

[Guirec Corbel]

Hello,

In the DCI principle, I like the Roles. It enable to have a skinny model with a single responsability (the persistence of the data).

I don't like the context. It can be useful for some specific cases like in this article : http://mikepackdev.com/blog_posts/24-the-right-way-to-code-dci-in-ruby. But I don't want to have something like this : https://github.com/randx/rails-dci-example/blob/master/app/controllers/documents_controller.rb. It's too complicated for nothing.

I have an alternative here : https://gist.github.com/GCorbel/5699834. It use service objects with roles. I think it's the best of both worlds.

What do you think?

This sums up what I think better than I could ever explain it myself:

Count me out as a fan of service objects.
