问题 Out of the blue, i am getting this error when doing a number of updates using nhibernate. Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [MyDomainObject] there is no additional information in the error. Is there some recommended way to help identify the root issue or can someone give me a better explanation on what this error indicated or is a sympton around. Some additional info I looked at the object and all of the data looks fine, it has an ID,

问题 I have a User table and an Address table. They are connected by a join table. The mapping for that is straight forward, but I have some data on the join table that I would like to show up on the Address table. There may be a better way to set this up also, which I'm open to suggestions for. Here is the table structure. CREATE TABLE [dbo].[User] ( [Id] INT NOT NULL IDENTITY PRIMARY KEY, ... ) CREATE TABLE [dbo].[Address] ( [Id] INT NOT NULL IDENTITY PRIMARY KEY, ... ) CREATE TABLE [dbo].

问题 Here is my codes; public List<SbtKlasorViewModel> GetFoldersWithIndexedDocuments() { //TODO - I can't find right query. We need folders with documents but only documents which be Indexed using (ISession session = DatabaseProvider.SessionFactory.OpenSession()) { List<DokumanlarModel> dokumanList = session.QueryOver<DokumanlarModel>() .Where(x => x.IndexlenmeTarihi != null) .List().ToList(); var list = dokumanList.GroupBy(x => x.Klasor.Aciklama); List<SbtKlasorModel> folders = list as List

问题 I'm struggling with fluent nhibernate from Fluent Nhibernate Many-to-Many mapping with extra column I've copied the mappings and written the smallest program I can... but it wont save...

问题 Look at the entity - class Person { int id { get; set; }; IList<PersonAddress> Addresses { set; get; } ... } Now while updating person from UI if I just remove some addresses from the list of address then I wand to actually delete the address record from db. currently this is updating the address table setting personId = NULL and not deleting the address record. Does anyone know how to do this. may be some mapping issue. Here I am adding whole Person class mapping file. public class

问题 i have this mapping: HasMany<ClassA>(ot => ot.AList) .Table("XPTO") .KeyColumn("IDXPTO") .Component(m => { m.Map(a=> a.X, "X"); m.Map(x=> x.Y, "Y"); }) .Cascade.AllDeleteOrphan(); i get an error saying that "refers to an unmapped class ClassA", but i shouldn't need to map it. i saw other examples in the internet with similar mappings and they don't have this problem... if i create a classMap for class A only with ID, then its works, but the data model will have 1 unecessary table for classA

问题 How to set up auto mapping to map System.Collections.Generics.ISet<T> correctly? I tried implementing IHasManyConvention , but in intellisense it seems that IOneToManyCollectionInstance does not have anything for that(?) 回答1: This is not up to Fluent NHibernate, because NHibernate just doesn't have any built-in implementation for System.Collections.Generics.ISet<T> . If you really want to use .NET's ISet instead of Iesi.Collections, for now you'll have to write it yourself. Use

问题 I'm in the process of adapting Fluent NHibernate to our existing legacy app and am trying to determine how to use ClassMap and SubclassMap for the entity hierarchy shown. // BaseObject contains database columns common to every table public class BaseObject { // does NOT contain database id column public string CommonDbCol1 { get; set; } public string CommonDbCol2 { get; set; } // ... } public class Entity1 : BaseObject { public int Entity1Id { get; set; } // other Entity1 properties } public
