fluent-nhibernate

OK, so here is the problem. Its not even as crazy as the guy who wants to map m:n with different column counts in his PKs. No matter what I do or where I look there seems to be no method chain that will result in a successful mapping of this. I have tried doubling up on the Parent and Child columns, eg ParentColumn("").ParentColumn("").ChildColumn("").ChildColumn("") - didnt' think it would work and I was right. Tried just using ForeignKeyConstraintNames no luck. Still FNH is mapping one side to a single key. public partial class M2M2ParentAMap : ClassMap<M2M2ParentA> { public M2M2ParentAMap()

I'm getting this exception (Full exception at the bottom): NHibernate.PropertyValueException was unhandled by user code Message="not-null property references a null or transient valueClearwave.Models.Encounters.Insurance.Patient" Source="NHibernate" EntityName="Clearwave.Models.Encounters.Insurance" PropertyName="Patient" I've done a lot of Googling and it seems the most common cause for that error is when an association is bi-directional but only one half has been set. As in: Insurance.Patient = Patient is called but Patient.Insurances.Add(Insurance) is not. I do, in fact, have a scenario

can someone tell me how to use nhibernate serach and lucene with fluent nhibernate. I have my application writen with fluent nhibernate but now i need full text serach but do not know how to implmenet nhibernate search with lucene to fluent nhibernate. i found this but it is not much and do not know how to use it: Fluent NHibernate + Lucene Search (NHibernate.Search) thx in advanced Lucene.net is a self-contained search and directory utility. As far as I know it cannot be integrated with nhibernate by mappings only. You should implement adding data to lucene index by yourself. Lucene allows to

I've been building an application with Fluent nHibernate/ASP.NET MVC - and I've dug around and figured out that it's considered most appropriate practice to keep a 'permanent' SessionFactory open, and then use sessions for each request to the database. Okay, this sounds good... I'm quite confused on how to accomplish this, though. Everything I find assumes an entire structured framework that uses some kind of IoC container system ...and that's just too advanced for what I have so far. Are there any more simple examples of how to implement this kind of design? I've taken a look at Where can I

I have an enum called Permissions. A user can be assigned permissions, or permissions can be asigned to a role and the user can be given a role. User and Role both have a property like this: public virtual IList<Permission> Permissions { get; set; } I want to use an enum for Permissions so in my code I can do things like public static bool UserHasPermission(Permission.DeleteUser) Right now I have about 50 different permissions in my enum. It would be nice if I didn't have to populate a mirror set of data in the database. My enum looks like this: public enum Permission { //site permissions 1-99

I'm looking into using NHibernate and Fluent NHibernate for my next project but one thing I'd like clearing up before hand is how do you manage changes to the database? eg, I have NH + FNH working, application has been deployed and is live but we make a change in the development environment, for example say we add a new property to a entity which is mapped using NH/FNH. How do you apply that change to the database without having to drop the table? Thank you GE I have very good experience using this framework: http://code.google.com/p/migratordotnet/ Basically you create a class for each

Please consider the following simple use case: public class Foo { public virtual int Id { get; protected set; } public virtual IBar Bar { get; set; } } public interface IBar { string Text { get; set; } } public class Bar : IBar { public virtual string Text { get; set; } } And the fluent-nhibernate map class: public class FooMap : ClassMap<Foo> { public FooMap() { Id(x => x.Id); Component(x => x.Bar, m => { m.Map(x => x.Text); }); } } While running any query with configuration, I get the following exception: NHibernate.InstantiationException : "Cannot instantiate abstract class or interface:
