automapping

问题 I have a tree structured model and designed it with composite Pattern. for iterating through the entire hierachy Im using Composite Iteration. I have used this tutorial: http://www.blackwasp.co.uk/Composite.aspx but when I want to AutoMap the model, I encounter this problem: {"The entity '<GetEnumerator>d__0' doesn't have an Id mapped. Use the Id method to map your identity property. For example: Id(x => x.Id)."} but getEnumerator is a method. I don't know why handle this like an Entity!!

问题 I'm trying to use the automap functionality in fluent to generate a DDL for the following model and program, but somehow I keep getting the error "Association references unmapped class: IRole" when I call the GenerateSchemaCreationScript method in NHibernate. When I replace the type of the ILists with the implementation of the interfaces (User and Role) everything works fine. What am I doing wrong here? How can I make fluent use the implemented versions of IUser and IRole as defined in Unity?

问题 Say I have these models: public class Person { public virtual int Id { get; private set; } public virtual ICollection<Address> Addresses { get; private set; } } public class Address { public virtual int Id { get; private set; } public virtual Person Person { get; set; } } I want FluentNHibernate to create the following tables: Person PersonId Address AddressId PersonId This can be easily achieved by using fluent mapping: public class PersonMapping : ClassMap<Person> { public PersonMapping() {

问题 I'm using Fluent NHibernate's AutoMap feature to map my entities. Most of my entities inherit from a base class Entity which has a property public IList<Tag> Tags . The tags are in a separate table in the database, so I use a many-to-many relation. But Fluent NHibernate creates mappings for a one-to-many relation. I'd like to write a convention to override these mappings to use HasManyToMany(...) if the class inherits from Entity . Is this possible and how? The convention could either rely on

问题 i have the following scenario public abstract class BaseClass { public virtual int Id {get; set}; public virtual string Name {get; set;} } public class FirstSubClass : BaseClass { //properties and behaviour here } public class SecondSubClass : BaseClass { //properties of SecondSubclass Here } public class ProcessStep { public virtual IList<BaseClass> ContentElements {get; set;} } for mapping i have used following code snippet :- this._sessionFactory = Fluently.Configure().Database

问题 Fluent NHibernate doesn't like this, throwing an error: {"Association references unmapped class: System.String"} OK fine, I can see why this would cause a problem - but what's the best solution? I don't really want it to store a delimited list of strings in a single field, this would get ugly if my list contains many strings. I also don't really want a table 'string', for obvious reasons. I guess I can solve this by wrapping my List<string> inside a class, but this feels a little heavyweight.

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 If using Fluent NHibernate, is it possible to automap most classes, but specify that a couple of particular classes should be mapped using the regular fluent API rather than being automapped? And if so, can anyone point me to some sample code that shows how to do it? Thanks! 回答1: It is possible and easy to mix-up mapping configurations: var cfg = Fluently.Configure() .Database(configurer) .Mappings(map => { // Automapping map.AutoMappings.Add(AutoMap.Assemblies(Assembly.GetExecutingAssembly()
