Something I learned when doing presentations: when someone asks a question, repeat it before answering so everyone can hear the question. None of the questions you answered were audible :-( http://ayende.com/3968/using-active-record-to-write-less-code#comment23http://ayende.com/3968/using-active-record-to-write-less-code#comment23Sat, 25 Apr 2009 19:23:54 GMTIs this required specific NHibernate library? I try to create the example by using AR, it doesn't work http://ayende.com/3968/using-active-record-to-write-less-code#comment22http://ayende.com/3968/using-active-record-to-write-less-code#comment22Sat, 25 Apr 2009 02:08:45 GMT@Ayende Fluent NH mapping of private members. [wiki.fluentnhibernate.org/.../StandardMappingPr...](http://wiki.fluentnhibernate.org/show/StandardMappingPrivateProperties) I think I like this one best Reveal.Property("Id") At least only as bad as XML :-) http://ayende.com/3968/using-active-record-to-write-less-code#comment21http://ayende.com/3968/using-active-record-to-write-less-code#comment21Fri, 24 Apr 2009 07:57:28 GMT"I don't have to think, let's do UML" - Love that one! http://ayende.com/3968/using-active-record-to-write-less-code#comment20http://ayende.com/3968/using-active-record-to-write-less-code#comment20Fri, 24 Apr 2009 07:45:31 GMTPeter, Try the FN mailing list http://ayende.com/3968/using-active-record-to-write-less-code#comment19http://ayende.com/3968/using-active-record-to-write-less-code#comment19Thu, 23 Apr 2009 17:47:14 GMTNor do I, which is why I have stuck with XML in my experimentation :-D http://ayende.com/3968/using-active-record-to-write-less-code#comment18http://ayende.com/3968/using-active-record-to-write-less-code#comment18Thu, 23 Apr 2009 17:41:57 GMTPeter, I have absolutely no idea :-) http://ayende.com/3968/using-active-record-to-write-less-code#comment17http://ayende.com/3968/using-active-record-to-write-less-code#comment17Thu, 23 Apr 2009 17:24:22 GMTHow does Fluent NH cater for protected / private state? http://ayende.com/3968/using-active-record-to-write-less-code#comment16http://ayende.com/3968/using-active-record-to-write-less-code#comment16Thu, 23 Apr 2009 17:23:43 GMTPeter, I now tend to more and more use NHibernate only. I used to use AR for speccing and prototyping, I use Fluent NHibernate for the same purpose. In both cases, there is some cut off point where I cut out the middle man and go to the XML. Trying to setup complex stuff in either AR or FN is just ugly. http://ayende.com/3968/using-active-record-to-write-less-code#comment15http://ayende.com/3968/using-active-record-to-write-less-code#comment15Thu, 23 Apr 2009 16:27:25 GMTThe slide in the video says November 2007, I presume that's wrong? Do you only use AR for prototypes and very simple apps then? Do you ever just use NH and leave AR out of the picture? http://ayende.com/3968/using-active-record-to-write-less-code#comment14http://ayende.com/3968/using-active-record-to-write-less-code#comment14Thu, 23 Apr 2009 16:23:42 GMTAndrew, Today? I would recommend going with Fluent NHibernate until your model has settled down, at which case I would move to HBM XML files, for custom configuration http://ayende.com/3968/using-active-record-to-write-less-code#comment13http://ayende.com/3968/using-active-record-to-write-less-code#comment13Thu, 23 Apr 2009 16:18:37 GMTGood presentation, I enjoyed a few of the other ones I skimmed through as well. As someone who has always worked for companies that are down right frightened of Open Source (especially for something as important as Data Access), I've only really played around with NHibernate and Active Record on my own. So my question is, with Fluent NHibernate now on the scene, does the need for Active Record go away, or will the three of them play nicely together? As a follow up, if I was going to start a medium sized project today (let's say something similar to the Hotel Reservation system from the presentation), would the ActiveRecord/NHibernate suffice, or would you (meaning anyone) suggest trying to integrate Fluent NHibernate into the project? Thanks in advance. http://ayende.com/3968/using-active-record-to-write-less-code#comment12http://ayende.com/3968/using-active-record-to-write-less-code#comment12Thu, 23 Apr 2009 16:03:41 GMTKrzysztof, No, that was not in 2007, it was in 2008. I think they had the wrong template :-) http://ayende.com/3968/using-active-record-to-write-less-code#comment11http://ayende.com/3968/using-active-record-to-write-less-code#comment11Thu, 23 Apr 2009 11:04:49 GMTJust seen it. indeed great presentation. "Give me a model to work on" was golden. But I think that date is wrong. If it was 2 months after NHibernate v2.1 was released it certainly was not 20 nov 2007. http://ayende.com/3968/using-active-record-to-write-less-code#comment10http://ayende.com/3968/using-active-record-to-write-less-code#comment10Thu, 23 Apr 2009 11:01:49 GMTJohn, I have never been able to measure the difference. Eric, Yes http://ayende.com/3968/using-active-record-to-write-less-code#comment9http://ayende.com/3968/using-active-record-to-write-less-code#comment9Thu, 23 Apr 2009 10:23:39 GMTDo you plan on releasing a new version of ActiveRecord soon? One that binds to NH 2.1 and fixes bugs like discriminators not being filtered with a HasMany. "Release early, release often" as the Google mantra goes http://ayende.com/3968/using-active-record-to-write-less-code#comment8http://ayende.com/3968/using-active-record-to-write-less-code#comment8Thu, 23 Apr 2009 09:41:09 GMTWhat's the performance of Castle ActiveRecord like? Is there much of a difference between it and NHibernate? Obviously it will be less efficient than NHibernate alone since it's built on top of it but how big is the gap? http://ayende.com/3968/using-active-record-to-write-less-code#comment7http://ayende.com/3968/using-active-record-to-write-less-code#comment7Thu, 23 Apr 2009 08:06:40 GMTFun presentation, thanks http://ayende.com/3968/using-active-record-to-write-less-code#comment6http://ayende.com/3968/using-active-record-to-write-less-code#comment6Thu, 23 Apr 2009 00:06:46 GMTAwww, no pretty.png ;-) http://ayende.com/3968/using-active-record-to-write-less-code#comment5http://ayende.com/3968/using-active-record-to-write-less-code#comment5Thu, 23 Apr 2009 00:02:37 GMTThis video is Public Using Active Record to write less code Ayende Rahien, We!, Israel Isn't this description like... not very up to date?
