I'm trying to get NHibernate to work. I've got this class: mm.k.Domain.Kampagne (namespace/assembly is mm.k.Domain) In another Visual Studio project (Assembly mm.k.Infrastructure) I got my Mapping files (in a Mappings directory), my hibernate.cfg.xml and some repositories. Heres my mapping file: <?xml version="1.0" encoding="utf-8"...
Using NHibernate I want to filter a collection in a class to contain ONLY a subset of possible objects. Below I am including a sample table data to help explain. I can find no way to do this using NHibernate. Table:DataObject DataObjectId(PK) / Name / CurrentVersion 11 "data.txt" 2 12 "info.txt" 3 Table...
Lets assume I have two tables Table tA ID ID2 SomeColumns Table tB ID ID2 SomeOtherColumns I am looking to create a Object let's call it ObjectA (based on tA), that will have a one-to-many relationship to ObjectB (based on tB).

I have the following idea: Business object implemented as interface or abstract class with certain properties as read only to all layers except the DAL layer. I also want my business objects in another assembly than the DAL (for testing purposes), so marking the properties is not an option for me. Examples could be one to one relations...

Now, I would like to use NHibernate to hook my Domain Model to a real database. I have a class Order which contains a list of OrderLines object public IList<OrderLine> OrderLines{ ... } //line 1 ...
I try to write a (fluent) mapping against an interface public interface IOrderDiscount : IDomainObject<long> where public interface IDomainObject<IdT> : IDomainObject { IdT Id { get; } } like so (and all other thinkable varieties of access strategies) Id(d => d.Id, "DiscountId") .GeneratedBy.HiLo("9") .WithUnsavedValue...
I have two C# classes, say Container and Item, and a unidirectional association: class Container { [...] public IList<Item> Items {get;set;} } The NHibernate mapping looks like this: <class name="Container"> [...] <list name="Items" cascade="all-delete-orphan"> <key column="ContainerId"/> <index column="Position"/> ...

We are adding an attribute(tags) to a system. The attribute table is just a relation table without any foreign keys. Is there a way to add to the criteria to generate a where clause for the attribute table on a parent table. <class name="Account" table="dbo.Account" lazy="true" > <id name="Id" column="`AccountId`"> <generato...
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...
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...

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 | +--------...
I am using automap to map a domain model (simplified version): public class AppUser : Entity { [Required] public virtual string NickName { get; set; } [Required] [DataType(DataType.Password)] public virtual string PassKey { get; set; } [Required] [DataType(DataType.EmailAddress)] public virtual string E...
Say i have a cms with only one object called Article (for the sake of this example) with an ID and a title. This CMS implementation becomes part of a framework and is used as a library: e.g. CMSFactory.CMS.SaveArticle(a); The problem is that depending on the project requirements an article object may have more fields such as SomeDate. I...
Hi I'm not sure if my problem is solvable in a more or less comfortable way. There is a class Person which has mapped 'hasOne' a participant. The person has a birthday but this field is not required on the person itself. But if I would like to add a participant to the person then the birthday is required. How to get rid of this mo...
Okay, I hope this makes sense! I have an object Box which contains Items in it. The database design is such that only inserts are done on the Items table, and negative quantities are inserted to represent items being removed from the box. For example, if you put 10 items in the box, and remove 3 items, this would result in 2 rows in the...
