fluent-nhibernate

I have the following tables: table A: FOO (PK) | CLIENT (PK) table B: BAR (PK) | CLIENT (PK/FK) | FOO (FK) PK -> primary key FK -> foreign key There's a one-to-many relation between A and B. I can't simply do this: class AMap { public AMap() { CompositeId().KeyReference(a => a.FOO) .KeyReference(a => a.CLIENT); HasMany(a => a.B); } } class BMap { public BMap() { CompositeId().KeyReference(a => a.BAR) .KeyReference(a => a.CLIENT); References(a => a.A); } } It will fail with the following exception: Foreign key (FKE7804EB3DA7EBD4B:B [FOO])) must have same number of columns as the referenced

do people build there own versions of all this? or is there a place to get all this prebuilt? I got the latest FluentNhibernate which has NHibernate but no Linq.... but I don't really want to setup a ruby rake build system etc etc unless I really really have to! Prefer to just get all the binaries I need. Here is a build: http://www.dennisdoomen.net/2009/07/nhibernate-210-ga-with-linq-and-fluent.html I build my own versions, because I don't want to be forced to upgrade all the dependencies of fluent when I just want to upgrade fluentnhibernate. Installing ruby is downloading and clicking one

I been reading nhibernate for beginners 3.0 and been reading about common mistakes(a few of them I been making) I am wondering what are some strategies for making one or more records readonly. Right now I get all the rows back and loop through them making them readonly through session.Readonly(). I like in the book that they do with fluent class EntityMap : ClassMap<Entity> { public EntityMap() { SchemaAction.None(); ReadOnly(); // Mappings } } What I am not sure is what happens if I need these records to not be Readonly? To me this means I have to make this exact same mapping minus those 2

I got the following classes: public class UserId { public UserId(int id){ //some validation } public override string ToString() {} } public class User { public UserId Id {get;set;} } How can I configure nhibernate/fluentnhibernate to use that class. The column is an int. as Diego mentioned it is not nessesaryly a good idea // UserMap Id(m => m.Id).CustomType<UserIdUserType>(); class UserIdUserType : IUserType { ... } 来源： https://stackoverflow.com/questions/9444056/using-custom-type-for-the-id-property

I had a mapping for a IDictionary<StocksLocation,decimal> property, this was the mapping: HasMany<StocksLocation>(mq => mq.StocksLocation) .KeyColumn("IDProduct") .AsEntityMap("IDLocation") .Element("Quantity", qt => qt.Type<decimal>()); Now i changed from decimal to a Value Object: Quantity . Quantity has two properties, decimal Value and Unit Unit (where Unit is an enum). I now have to map IDictionary<StocksLocation,Quantity> , how can i achieve this? Thanks in advance Daniel Schilling Option 1: Map it as an Entity I'm guessing that your table looks similar to this: CREATE TABLE Quantity (

I'm developing a website with ASP.NET MVC, NHibernate and Fluent Hibernate and getting the error " no session or session was closed " when I try to access a child object. These are my domain classes: public class ImageGallery { public virtual int Id { get; set; } public virtual string Title { get; set; } public virtual IList<Image> Images { get; set; } } public class Image { public virtual int Id { get; set; } public virtual ImageGallery ImageGallery { get; set; } public virtual string File { get; set; } } These are my maps: public class ImageGalleryMap:ClassMap<ImageGallery> { public
