[LRUG] Rails - The Missing Parts

[Stephen Best]

@Mike Good one! I can totally imagine someone giving that excuse. The problem is it's missing the point of DCI. 

In that case your method privacy is at the wrong level, just have your decorator not expose that method. If you have to rely on always having the decorator that's fine, object composition is a thing that should be done.

* I know that an object must delegate all methods to be a true decorator, no trolls plz.
