OK, no matter how I define these mappings, my many-to-many mapping does not want to work with cascade insert. I have tried various combination of Cascade() with Reverse() and removing all unnecessary properties just to understand if they had anything to do with this not working, but no lock. It is really Simple stuff: I have a Message (like an email) which is sent from a user (I have called the entity BasicUser ) to a number of users (through property To ). User and Message in terms of recipients have a many-to-many relationship but FromUser has one-to-many. FromUser works fine and it is

I am using Fluent NHibernate and am trying to store an image. Small images work, but larger images do not, and I receive this error when saving to the database (SQL Server): Exception: Error dehydrating property value for CFC.Domain.Vehicle.Image Inner Exception: The length of the byte[] value exceeds the length configured in the mapping/parameter. Here is my mapping: mapping.Table("Vehicle"); mapping.Id(x => x.Id, "VehicleID"); mapping.Map(x => x.Year).Not.Nullable(); mapping.Map(x => x.Image).CustomSqlType("VARBINARY(MAX)").Length(int.MaxValue); The "Image" property is a byte[]. Note the

I have a person entity containing an Address as a value object: public Person() { WithTable("Person"); Id(x => x.Id); Component<Address>(x => x.Address, a => { a.Map(x => x.Address1); a.Map(x => x.Address2); a.Map(x => x.Address3); a.Map(x => x.Town); a.Map(x => x.Postcode); }); } It states in the NHibernate docs that if all the properties of a value object (Address1, Address2 etc) are null, the entire component will be mapped as null (i.e. Person.Address will be null). This is giving me problems in cases where all address fields are null because in my pages where I might have (I'm doing ASP

using fluent nhibernate, and automappings (nhibernate creates my db schema), how can i get nhibernate to create a nvarchar(max) column in the database based on the following class public class VirtualPage : BaseEntity { public virtual int ParentId { get; set; } public virtual string PageName { get; set; } public virtual string Title { get; set; } public virtual string Body { get; set; } public virtual string ViewName { get; set; } public virtual string ViewData { get; set; } // this must be nvarchar(max) } With automapping you can override the default length for text fields, but it will be

I have my nHibernate setup and working correctly with QueryOver for most queries, however, whenever I try to do a HQL CreateQuery I get the exception that the entity isn't mapped. I can confirm that the same entity works fine using QueryOver. Note: I am using fluent nHibernate Any ideas what would cause this? If you have disabled auto-import in your mappings ( <hibernate-mapping auto-import="false"> ), then you will have to use fully-qualified class names everywhere in your queries, unqualified class names won't work. Otherwise, enable auto-import. Conventions.Setup(x => { x.Add

I want to add an event listener ( IPreUpdateEventListener ) to add NHibernate but I can't seem to find an example when using a fluent configuration. I want to be able to add the listener when I create the session factory, e.g. when the following code is execute. _sessionFactory = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString(connectionString).ShowSql()) .Mappings(m => m.FluentMappings.AddFromAssemblyOf<IEntity>()) .BuildSessionFactory(); Anyone know how to do this? Late answer, found your question when I was trying to do the same. Found a solution that should

Is there any way to create a naming convention for my primary key constraints in Fluent NHibernate? I know you can name foreign key constraints, but it does not appear possible to name the primary key constraint. James Gregory from FNH says... No, that's not supported through NHibernate, so we can't support it either. http://groups.google.com/group/fluent-nhibernate/browse_thread/thread/9ea7155407d33772 来源： https://stackoverflow.com/questions/1358043/fluent-nhibernate-primary-key-constraint-naming-conventions
