FluentNHibernate Lookup Table
This is possibly an easy one that I can't seem to get past. I've created a "Product" class which has a list of "Accessories". Each "Accessory" is just another product referenced by a lookup table.

How to create NHibernate Criteria for Map/Dictionary associations
Hi all, I have a Fluent NHibernate mapping like this. public PersonMap() { Table("PERSON"); Map(x => x.FirstName) .Not.Nullable(); Map(x => x.LastName) .Not.Nullable(); HasMany(x => x.Ids) .AsMap<string>("id_type") .Cascade.SaveUpdate(); } So I could do something like this.

NHibernate.Spatial and Sql 2008 Geography type - How to configure
I am trying to use Nhibernate with the Sql 2008 Geography type and am having difficulty. I am using Fluent Nhibernate to configure which I am fairly new to so that may be the problem as well.

Is it possible to use both automapping and schema generation with Fluent NHibernate?
I'm using the following: Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString(connectionString)) .Mappings(m => m.AutoMappings.Add(AutoMap.AssemblyOf<Incident>() .Where(t => t.Namespace.StartsWith("EDA.DomainModel.POCO")))) .ExposeConfiguration(BuildSchema) .BuildSessionFac...
Mapping nested components in Fluent NHibernate
Hi all, I have a 'User' Entity that contains an 'Address' Value Object. I have this mapping ok using FNH's Component concept. However, the Address VO also contains a Country which is another value object. I had assumed that this should be just nested as another component, but this doesn't seem to work. Can anyone tell me how I shoul...
FluentNHibernate mapping to a view
I have a many to many relationship between entities and there is a table view acting as a lookup table defining the relationship. I'm curious how to map to a view as opposed to a table within a database. ie, Table mapping: public SomeMap() { Id(...)//set Id and other mapped properties HasManyToMany(x => x.Items) .Table("S...
Parent save doesn't cascade to children of same abstract in FNH
I am using AutoMapping in FNH 1.0 (with Tom Cabanski's modified #arch from 9/2009) to persist a parent-child relationship. The parent and child, Managers and Employees, are both of type User. Managers has a collection of DirectReports of IList because a Manager can have another manager as a direct report. I have a test where I instant...
Fluent NHibernate HasManyToMany only works on first load

I set up my Fluent mappings as so public partial class Carrier { public virtual int ID { get; set; } public virtual string Name { get; set; } public virtual IList<Company> Companie...
Id property not populated
I have an identity mapping like so: Id(x => x.GuidId).Column("GuidId") .GeneratedBy.GuidComb().UnsavedValue(Guid.Empty); When I retrieve an object from the database, the GuidId property of my object is Guid.Empty, not the actual Guid (the property in the class is of type System.Guid). However, all of the other properties in the o...
Fluent NHibernate HasMany Collection Problems
Update: It appears that changing my mapping from Cascade.All() to Cascade.AllDeleteOrphan() fixes most of my issues. I still have to explicitly set the Company property on the OperatingState, which seems unnecessary as it's being added to the Company entity, but at least I can work with that during an update. I still need to test that wi...
Hibernate complex Mappings
We use a pesonal design to store modified rows. For the data we need to keep, we use 2 tables; the first with fields that don't change, the second uses soft delete. +----------+ +---------------+ | TableBase| | Table | +==========+ +===============+ | Id | | TableId | | FieldA | | Id | +--------...
Is it possible to use NHibernate without altering a DDD model that is part of a framework
I dig a lot of things about the DDD approach (Ubiquitous language, Aggregates, Repositories, etc.) and I think that, contrary to what I read a lot, entities should have behavior rather then being agnostic. All examples I see tend to present entities with virtual automatic properties and an empty constructor (protected or worst, public) a...
Fluent NHibernate Automap does not take into account IList<T> collections as indexed
