php

I have a model "news item" which contains text, image etc to display as latest news on several pages in a website. This "news item" can also be posted to Twitter or Facebook. Is it clean to implement a method post inside the news item model and inject the different post implementations as a strategy? Or is it better to have a separate application service for this?

Thanks

Domain model: should things like Logging, Audit, Persistence be in it

I'm having a hard time convincing our architect that a Domain model should only have the essential elements of the business domain on it. Things like the fact that a class is persistable, that it needs logging and auditing and that it has a RESTful URI should not drive the domain model. They can be… >>> More
