Data Context Interaction in a minute
Raw
gistfile1.txt
Caveat: I have not read James Coplien book about DCI.
But to put simply: Data Context Interaction (Roles) is a technique to capture the run-time behavior of your system. I'll leave the benefits to your imagination, and gleaning from further reading of numerous sources about the subject.
How do we apply DCI to Rails? Here's one proposed folder structure:
app/contexts/
app/roles/
app/models/
app/contexts/ holds your contexts. app/roles/ holds your roles. app/models holds your dump data. When viewing app/contexts/ each file reflects a use case of your application, and taken as a whole screams what your application is all about.
