So, I have a nice domain model built. Repositories handle the data access and what not. A new requirements has popped up that indicates that reasons need to be logged with deletes.

Hi, I was wondering if this seemed to familiar to any experience NHibernate developers or if someone could give me an idea as to where to start to try and resolve this issue: I inherited an NHibernate site written in ASP.NET 1.1 using NHibernate 0.6 and .NET remoting to the DAL layer residing on the database server.

I found an example of implementing the repository pattern in NHibernate on the web, and one of the methods uses this code to get the first result of a query: public IEnumerable<T> FindAll(DetachedCriteria criteria, int firstResult, int numberOfResults, params Order[] orders) { criteria.SetFirstResult(firstResult).SetMaxResults(numb...
I use NHibernate for my dataacess, and for awhile not I've been using SQLite for local integration tests. I've been using a file, but I thought I would out the :memory: option. When I fire up any of the integration tests, the database seems to be created (NHibernate spits out the table creation sql) but interfacting with the database c...

During my apprenticeship, I have used NHibernate for some smaller projects which I mostly coded and designed on my own. Now, before starting some bigger project, the discussion arose how to design data access and whether or not to use an ORM layer. As I am still in my apprenticeship and still consider myself a beginner in enterprise prog...
Is there any smart way to do this? If using Linq2Nhibernate, you really seem to have to rely on HQL or the likes to do multiple deletes from a database (without loading up and deleting one by one)? It doesn't seem like Linq2Sql have it either? I just want something that can do stuff like: DELETE FROM Accounts WHERE amount < 1000 Any...
I have classes BidiParent and BidiChildList which link parents and children in a bidirectional parent-child relationship. If a child's parent is updated by e.g. the service layer, the old and new parents' children lists are automatically updated to reflect the change. Likewise, if a parent's children list is updated by e.g. adding a new ...

I use MyGeneration along with nHibernate to create the basic POCO objects and XML mapping files. I have heard some people say they think code generators are not a good idea. What is the current best thinking? Is it just that code generation is bad when it generates thousands of lines of not understandable code? ...
Hi, I keep getting an NHibernate.PersistentObjectException when calling session.Save() which is due to an uninitialized proxy passed to save(). If I fiddle with my cascade settings I can make it go away, but then child objects aren't being saved. The only other fix I have found is by adding the following to my DefaultSaveEventListener...
