fluent-nhibernate

问题 I'm using Fluent NHibernate with DiscriminateSubClassesOnColumn() to support subclassing. The column used to discriminate between subclasses is not mapped to an actual property on the entity. How do I create a query which returns only entities of a given type? Here's my try, where propertyName is the name of my discriminating column and value is the type name: return _db.CreateCriteria<T>() .Add(Restrictions.Eq(propertyName, value)) .List<T>(); However this gives me the error "could not

问题 I thought of using Fluent nhibernate for data access with my asp.net mvc web application...Any good article that describes about the setup of Fluent nHibernate with asp.net MVC web application... 回答1: This series of articles is what I started with. I don't believe it's exactly what I ended up going with, but it's a good start. 来源： https://stackoverflow.com/questions/3011937/getting-started-with-fluent-nhibernate-and-asp-net-mvc

问题 I have a convention UserTypeConvention<MyUserType> where MyUserType : IUserType where MyUserType handles an enum type MyEnum . I have configured Fluent NHibernate thusly sessionFactory = Fluently .Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString( c => c.Is(connectionString)) ) .Mappings( m => m .FluentMappings .AddFromAssemblyOf<A>() .Conventions .AddFromAssemblyOf<A>() ) .BuildSessionFactory(); where A is a type in the same assembly as UserTypeConvention<MyUserType> and

问题 The references are unidirectional. The table (StoreProduct) for this entity is actually a join table that has these fields: Store_id Product_id ExtraBit So I went with an entity having a compoundID (store_id and product_id) and the ExtraBit is just a string: public class StoreProduct { protected StoreProduct():this(null,null,null){ } public StoreProduct(Store c_Store, Product c_Product, String c_ExtraBit) { Store = c_Store; Product = c_Product; ExtraBit = c_ExtraBit; } public virtual int

问题 According to the REST philosophy, a PUT request should update the resource at a URL if it exists, and create it if it doesn't exist. So in other words, if I use the following URL: PUT http://server/item/5 If an Item exists with an ID of 5, it will be updated. If an Item doesn't exist with an ID of 5, a new Item will be created with an ID of 5. However, I'm using NHibernate for persistence, and I mapped my IDs as Identity . This means that no matter what value I assign the ID, NHibernate will

问题 I recently upgraded FluentNHibernate from v1.1.0.685 to v1.2.0.712 (latest) for NHibernate 2.1 . My issue appears to be with classes that use the Component().ColumnPrefix() mapping. For example, public class Address{ public string Street {get; set;} public string Zip {get; set;} } public class AddressMap : ComponentMap<Address>{ Map( x => x.Street ); Map( x => x.Zip ); } public class PersonMap : ClassMap<Person> { public PersonMap(){ Id( x => x.Id ); Map( x=> x.Name ); Component( x => x

问题 I'm new to the whole castle Windsor, Nhibernate, Fluent and Automapping stack so excuse my ignorance here. I didn't want to post another question on this as it seems there are already a huge number of questions that try to get a solution the Windsor nhib Isession management problem, but none of them have solved my problem so far. I am still getting a ISession is closed exception when I'm trying to call to the Db from my Repositories,Here is my container setup code. container.AddFacility

问题 Using fluent NHibernate I have a property on a class mapped using Version Version(x => x.Version); When I save the object, the Version property gets incremented in the database as I would expect, but the value of the property on the object only seems to change sometimes. using (var tx = session.BeginTransaction()) { session.Merge(item); tx.Commit(); item.Version; // Sometimes this is still 1, when I expect it to be 2. } The problem is then that if it remains as 1 and I make more changes and

问题 I have a simple three table DB with many-to-many relation. A(id, Name) B(id, Name) AB(AId, BId) references A and B The corresponding classes: public class A { public virtual int Id { get; set; } public virtual string Name { get; set; } } public class B { public virtual int Id { get; set; } public virtual string Name { get; set; } } public class AB { public virtual A A { get; set; } public virtual B B { get; set; } public override bool Equals(object obj) { /* routine */ } public override int

问题 I'm looking for a FluentNH (Fluent NHibernate) convention or configuration that ignores all properties that have no setter: It would still map these: public class foo{ public virtual int bar {get; private set;} } And omit these: public class foo{ public virtual int fizz{get;private set;} public virtual int bar{get {return fizz;}} //<------- } 回答1: You should use a custom mapping configuration public class DefaultMappingConfiguration : DefaultAutomappingConfiguration { public override bool
