Out of interest, who decides this sort of stuff?

I've just been introduced to it a few weeks ago through a work colleague who was discussing domain driven design, and I'm very impressed with what I've already seen. One thing I wanted to do was add validation to my business logic. I found that Hibernate has a Validator class which is just what I'm looking for: http://www.hibernate.org/hib_docs/validator/reference/en/html_single/ To me it looks like you can just annotate the domain model within the class (or even the interface!) with the constraints, e.g. min & max text length, min & max numeric value, not null, regular expression patterns, and others. It then allows validation by listening on Hibernate's PreInsertEvent and PreUpdateEvent, and also provides ability for application level validation, and presentation layer validation. I was very excited when I found that NHibernate includes a "Child project"called NHibernate.Validator however I can't figure out how to annotate my domain model. I've looked through the NHibernate download (I'm running a C# project with .NET 2.0). I even tried looking through the "2.0.0.Alpha1-src" but couldn't figure it out. How do I annotate my properties with the Hibernate equivalent of @Length, @Max, @Min, etc? If it's available, that would be great because it would provide a single point to annotate data constraints, then allow the web interface to display and trap data validation errors, and do a final check with NHibernate before the insert or update. Thanks for your time and thanks again for all your great work!

I mean will Linq 2 NH 'cover all bases' allow a dev to query without using Criteria (and HQL for that matter). - Andy http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment26http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment26Sat, 19 Apr 2008 07:28:42 GMTOren, Great news. Team has just upgraded so looking forward to good things ... 3 questions, 1 relevant but all related: 1) Does the NHibernate Query Generator work with NHibernate 2? 2) Can you use NHG interchangably with DetachedCriteria (and Criteria)? 3) Will Linq to NHibernate supercede both NHG and DetachedCriteria/Criteria?

The WCF interface contract could be considered in fact a public application-level protocol, that shouldn't be affected by your internal domain. Trying to pretend that the network does not exist and that you can treat the data coming from the network as if it was coming from another layer in your application is a common error that makes people expose horrible application-level network protocols (WCF contracts, WSDLs and that) that change often and show too much internal details to the world. http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment21http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment21Fri, 04 Apr 2008 00:07:11 GMTYou better ask in the mailing list. http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment20http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment20Wed, 02 Apr 2008 20:29:06 GMTHello Ayende, How can I with NHibernate POCOs with WCF? I have not found a comprehensive solution for this matters.

I'm guessing no, as I don't really see how to make that happen in my repositories without a direct dependency on NHIbernate, but I figured I'd ask anyway. thanks, James http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment17http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment17Wed, 02 Apr 2008 18:40:24 GMTPaul, It is compatible on the trunk http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment16http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment16Wed, 02 Apr 2008 13:36:11 GMT1/ Fairly well, I would say. We have some features they don't have, and vice versa. You would have to be more specific about things. 2/ Wasn't done for this release, and yes, this is a problem in some scenarios http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment15http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment15Wed, 02 Apr 2008 12:01:23 GMTGreat stuff! I do have two questions: 1) Given all of these updates, how does NHibernate compare feature-wise to the latest version of Hibernate? 2) I seem to recall there was talk of a rewrite of the HQL parser. Did this happen? If I am not mistaken, there are some limitations of the current parser that were fixed in Hibernate. http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment14http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment14Wed, 02 Apr 2008 11:58:24 GMTI was wondering where Castle.ActiveRecord is in terms of support for this release.

Where are you getting these fancy logo's from? :) http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment10http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment10Mon, 31 Mar 2008 19:09:11 GMT@Julian I'm helping out on the "NHibernate in Action" book, and I believe it would be great to see it revised to include some NHibernate 2.0 specific stuff. I'll have a chat with Kuate and Manning and post up what the plan is. http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment9http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment9Mon, 31 Mar 2008 19:00:08 GMTConsider this as an open invitation, then :-) http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment8http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment8Mon, 31 Mar 2008 10:51:35 GMTI would really, really love to get involved - but there are a few things stopping me at the moment in terms of time and some professional contract concerns. However, those *may* resolve themselves in the next month or so - I'll keep bearing it in mind :) http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment7http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment7Mon, 31 Mar 2008 10:49:21 GMTLinq for NHibernate is handled as a separate project at the moment, until we get enough critical mass behind it to roll it into NHibernate. Help is always appreciated. http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment6http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment6Mon, 31 Mar 2008 10:37:24 GMTWhere does LINQ to NHibernate fit into NHibernate 2.0, out of interest? I haven't kept track of whether it's now part of the NHibernate release, or whether it's separate. Any comments on the current state of play and the potential future position? http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment5http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment5Mon, 31 Mar 2008 10:26:07 GMTRestrictions is the Hibernate term. Expression is there and still works, but the documentation will refer to Restrictions. http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment4http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment4Mon, 31 Mar 2008 10:14:39 GMTJulian, To the best of my knowledge, no. But I am not sure about that http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment3http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment3Mon, 31 Mar 2008 10:13:37 GMTCan you explain a little more on this: Guidance: Prefer to use the Restrictions instead of the Expression class for defining Criteria queries. Why is Restrictions preferred and why we should switch to it ? Is Expression only included for backward compatibility ? Will it be depreciated at some point in the future ? Thanks http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment2http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment2Mon, 31 Mar 2008 08:21:08 GMTThis is great news. As a slight aside, do you happen to know how much of this new functionality is included in the NHibernate In Action book? Just wandering whether it is still a good book to buy or whether it would be better to hang out for something that covers the version 2 functionality. http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment1http://ayende.com/3239/nhibernate-2-0-alpha-is-out#comment1Mon, 31 Mar 2008 08:10:20 GMT
