If it accesses that, it’s a Controller, no matter where you put it. Now, can you pass what you need into the class in lib? And if the class is modular (even if it has no database hooks), should it be a model? And do you have unit tests on it, so you can refactor it as you learn the best role for it? (But note that questions which are actually about Merb belong on its cheerful, friendly, and mature mailing list…) ---

For the same reason a lib item can’t see the request. Just pass the request into your top method. > not unit tests for it (for the moment) Write the tests first! Don’t write them “last” - you will have no incentive to get back to it. ---

Better than passing the whole object in? you said you need the whole object; go ahead and rely on OO and encapsulation. There’s nothing architecturally wrong with passing a whole object in. The Merb mailing list might have other ideas… news://news.gmane.org:119/gmane.comp.web.merb.devel …but be prepared to answer the same questions as I asked.
