fluent-nhibernate

问题 I found a fantastic template for NHibernate code generation using MyGeneration here, http://vucetica.blogspot.com/2009/01/nhibernate-template-for-mygeneration.html This creates XML mapping files with the extension hbm.xml. I was wonder if anybody knows of templates which support fluent NHibernate which defines the mapping using C# files. Thanks 回答1: When you are using Fluent NHiberate you needn't hbm files, you can generate them based on your domain model and conventions 来源： https:/

问题 I founded that NHibernate have several builtin Types that are not present in C# , but are present in some of SGBD. Now I have following: public class TimeSlot : EntityBase { public virtual NHibernate.Type.TimeType FromTime { get; set; } public virtual NHibernate.Type.TimeType ToTime { get; set; } } public class TimeSlotMap : ClassMap<TimeSlot> { public TimeSlotMap() { Id(c => c.Id).GeneratedBy.Identity(); Map(c => c.FromTime); Map(c => c.ToTime); } } In MSSQL this table look like in attached

问题 I have the following SessionFactory for Fluent NHibernate. I am getting an error of An invalid or incomplete configuration was used while creating a SessionFactory. with an InnerException of An item with the same key has already been added. This problem is only happening occasionally and my application works fine most of the time. Based on NHibernate: System.Argument Exception : An item with the same key has already been added I'm guessing my class is not thread-safe which would explain the

问题 I'm trying to create a discriminator column. This column would hold one of the many statuses available. Like my code will show, each status has a name as well as a background color. Each status shares the same base class.

问题 I am attempting to create a simple database application which keeps track of loans of various types of equipment using Fluent NHibernate and SQLite. However, when I try to generate the database structure with SchemaExport for use in unit testing, foreign keys for one-to-many relationships aren't created. Here is my Equipment entity: public virtual int Id { get; set; } public virtual EquipmentType Type { get; set; } public virtual int StockId { get; set; } And here are my mappings for

问题 I am brand new to NHibernate and Fluent NHibernate and I am trying to get the following confguration to work. private static ISessionFactory CreateSessionFactory() { return Fluently.Configure() .Database( OracleDataClientConfiguration.Oracle10.ConnectionString("Data Source=mysource;User ID=myid;Password=mypwd;") ) .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Program>()) .BuildSessionFactory(); } I have the Oracle.DataAccess assembly referenced. I am using VS 2010 and .Net 4 I get the

问题 I have an abstract class and subclasses of this, and I want to map this to my database using NHibernate. I'm using Fluent and how to do the mapping. But when I add the mapping of the subclass an NHibernate.DuplicateMappingException is thrown when it is mapping. Why? Here are my (simplified) classes: public abstract class FieldValue { public int Id { get; set; } public abstract object Value { get; set; } } public class StringFieldValue : FieldValue { public string ValueAsString { get; set; }

问题 How do I specify with fluent NHibernate mapping for a table that doesn't have an identity column? I want something like this: public sealed class CustomerNewMap : ClassMap<CustomerNew>, IMap { public CustomerNewMap() { WithTable("customers_NEW"); Not.LazyLoad(); Not.Id(); // this is invalid... Map(x => x.Username); Map(x => x.Company); } } I mean no primary key defined in the database (not much defined in the database). 回答1: I found the answer to be: public CustomerNewMap() { WithTable(
