The list of _available_ filters is just a list of types, and the only addition metadata we needed was the display name. http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment7http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment7Mon, 31 Aug 2009 15:20:22 GMTKyle, I am leaning toward must not. http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment6http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment6Wed, 26 Aug 2009 04:07:28 GMTMike, I would say that CRUD is a concept and a CRUD screen is a feature in this concept http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment5http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment5Wed, 26 Aug 2009 03:54:42 GMT@Kyle - I would assume that Should Not would quickly devolve into usually does which becomes always does. Then the lines between Concepts & Features blur and your app becomes a big ball again making it difficult to add new features to your app. @Ayende - I like this approach a lot. Would you consider this a valid approach for simple CRUD apps or is this overkill? I've done something like that before where you'd call a concept one of the standard actions (create, list, edit/update, delete, view) and each feature is essentially a new screen with UI and a presenter that dictates where the data comes from/goes. http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment4http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment4Tue, 25 Aug 2009 23:33:48 GMTJust a quick clarification: When you say, "May not involve", do you mean CANNOT, or should not? I'm assuming the former because it's you posting, but the latter seems more likely, just given systems I've seen. :) http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment3http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment3Tue, 25 Aug 2009 16:06:14 GMTNice post again. Could you explain why you have defined display name as an attribute and not as a read-only property? http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment2http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment2Tue, 25 Aug 2009 14:53:30 GMTWhen I see the code base I inherited to maintain and this blog entry, it looks like magic :( http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment1http://ayende.com/4144/concepts-features-in-nh-prof-filtering#comment1Tue, 25 Aug 2009 05:54:13 GMT
