nhibernate

问题 I am having an issue with many-to-many mapping using NHibernate. Basically I have 2 classes in my object model (Scenario and Skill) mapping to three tables in my database (Scenario, Skill and ScenarioSkill). The ScenarioSkills table just holds the IDs of the SKill and Scenario table (SkillID, ScenarioID). In the object model a Scenario has a couple of general properties and a list of associated skills (IList) that is obtained from the ScenarioSkills table. There is no associated IList of

问题 I'd like to have a single configuration file and then when I'm creating a session change the hibernate-configuration->session-factory->connection.connection_string property to what I want it to be programmatically? Is it possible? UPDATE: I believe I may be able to do this like this Configuration cfg = new Configuration(); cfg.Configure(sessionFactoryConfigPath); cfg.Properties["connection.connection_string"] = ... What I would wonder than, if that is ok, Is this a bad way to handle

问题 i am trying to update record with nHibernate. I tried several solutions, but none of them work (shows no error, bu data is alsno not updated). First code: MyRepository rep = new MyRepository(GetCurrentSession()); UserPost post = rep.GetById(id); post.ValidTo = date; rep.Update(post); Second code: ISession session = GetCurrentSession(); MyRepository rep = new MyRepository(GetCurrentSession()); UserPost post = rep.GetById(id); post.ValidTo = date; rep.Update(post); session.Update(post); session

问题 all! I am learning NHibernate now and I would like to know is it possible to save multiple objects to database in one operation. For example, consider this test code private static void SaveTestBillNamesInSession(ISession session, params string[] names) { var bills = from name in names select new Bill { Name = name, DateRegistered = DateTime.Now, }; foreach (var bill in bills) session.SaveOrUpdate(bill); } This loop here generates many INSERT statements which may be sub-optimal in SQL Server

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . Is there a visual designer similar to Mindscape's NHibernate designer for Fluent NHibernate? I have decided to move from EF4 to NH3, but without a visual design interface it is going to be a hard sell to my team who are used to the EF4 model creation interface. 回答1: I've only heard of Mindscape's NHibernate

问题 I've always taken a data centric approach to web apps, and so the paradigm change involved when taking a pure OO approach using ORMs is still not completely natural to me, and evey now and then something ostensibly simple is not obvious. Can someone please point me into the right direction of how to correctly model this situation in an ORM (Specifically NHibernate). The situation: There are many Users, Many Items, users may rate Items. In a data centric/relational approach it would look like

问题 We are in the process of splitting our db into several smaller ones. The schemas will be exactly the same and we will control which db the system connects to when the client logs in. I receive an error if I do not set a connection string in my nhibernate configuration. I do not want to create a factory for each db. Is it possible to have a session factory provide a Session that I can set the connection string before using it? 回答1: Have not used it but there is a method ChangedDatabase on the

问题 I'd like to have NHibernate call a stored procedure when ISession.Get is called to fetch an entity by its key instead of using dynamic SQL. We have been using NHibernate and allowing it to generate our SQL for queries and inserts/updates/deletes, but now may have to deploy our application to an environment that requires us to use stored procedures for all database access. We can use sql-insert, sql-update, and sql-delete in our .hbm.xml mapping files for inserts/updates/deletes. Our hql and

问题 I'm using SharpArchitecture in an ASP.NET MVC 3 application. Everything works wonderfully. Using SharpArchitecture's NHibernateInitializer to initialize a new Session per request like so: protected void Application_BeginRequest(object sender, EventArgs e) { NHibernateInitializer.Instance().InitializeNHibernateOnce(InitializeNHibernateSession); } private void InitializeNHibernateSession(ISessionStorage sessionStorage) { NHibernateSession.ConfigurationCache = new
