问题 I'm mapping my database tables using NHibernate with NHibernate.Mapping.Attributes library and I got stuck to get the Filter attributes to work. Suppose a class A that has a set of objects of class B. So, I have, the following: [NHibernate.Mapping.Attributes.Set(0, Inverse = true, Lazy = NHibernate.Mapping.Attributes.CollectionLazy.False)] [NHibernate.Mapping.Attributes.Key(1, Column = "ClassAId")] [NHibernate.Mapping.Attributes.OneToMany(2, Class = "ClassB, Assembly")] public virtual ISet

问题 I am having this annoying error while running my Nhibernate project. It was running okey and all of a sudden it just start asking for a file in this path "d:\CSharp\NH\NH\nhibernate\src\NHibernate\Bytecode\AbstractBytecodeProvider.cs" and when cancel, it throws an exception saying it says Unable to load type 'NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle' during configuration of proxy factory class. Possible causes are: - The NHibernate.Bytecode provider assembly

问题 I have a table storing purchased items and the entity class using in NHibernate: public class PurchasedItem { public virtual int Id { get; set; } public virtual Product Product { get; set; } public virtual int SortSale { get; set; } } I would like to reduce the code duplication by getting all records from the PurchasedItems table ( IList <PurchasedItem> object). Records have been sorted in descending order by SortSale column. What's the best way of creating WrapPanel buttons based on the

问题 What I want to do is to populate SelectList with categories from a categories repository. A little mockup http://mockupbuilder.com/App/15379. What I have now is a controller: [HandleError] public class ProductController : Controller { private IRepository<Product> exhibitions; private IRepository<Category> categories; private readonly Int32 PageSize = 18; // ctor ... [HttpPost] public ActionResult Create(Product product, Guid categoryId) { // validation ... // properties setting ... product

问题 There is an extension to Entity Framework called Future Queries that allows queries to be batched up and processed at the same time. For example, from their docs: // build up queries var q1 = db.Users .Where(t => t.EmailAddress == "one@test.com") .Future(); var q2 = db.Tasks .Where(t => t.Summary == "Test") .Future(); // this triggers the loading of all the future queries var users = q1.ToList(); Is there any equivalent in NHibernate, or an extension that might give this type of functionality

问题 I get null values from inside class mapping with nHibernate, please see below: public class IndicadorRepository : Repository<IndicadorRepository> { ... public Indicador FindById(int indicadorId) { return _session.Get<Indicador>(indicadorId); } ... } Repository.cs public class Repository<T> where T : Repository<T>, new() { /* Properties */ protected static T instance; public ISession _session; public static T Instance { get { if (instance == null) instance = new T(); return instance; } } /*

问题 I have been looking into Fluent Nhibernate, and it seems really promising. But... I can't seem to get it working with a MySQL database. I have the Fluent Nhibernate example project running fine with the SQLite database (Fluent NHibernate: Getting Started), but as soon as I change the database configuration to this: return Fluently.Configure() .Database(MySQLConfiguration.Standard.ConnectionString( x => x.Database("database") .Server("server") .Username("login") .Password("password") ) )

问题 Instead of getting into code, I have a simple question. Default behavior for a simple one-to-many is that it inserts the child record then updates the foreign key column with the parent key. Has anyone ever had a one-to-many where the child object gets inserted but not updated resulting in a row in my table with a null in the foreign key column? I want the default behaviour for a standard one-to-many. I don't want to have to add the parent as a property to the child. Thanks. 回答1: This would
