fluent-nhibernate

问题 This question has been asked already but there was no decent answer. Is there a property name convention for fluent nhibernate so that instead of looking for Id it looks for ProductId ? PrimaryKeyConvention applies to the column names in the database, NOT the property names. Consider this scenario: public class Product { public int ProductId { get; set; } public string Name { get; set; } } public class AutomappingConfiguration : DefaultAutomappingConfiguration { public override bool ShouldMap

问题 We're using NCommon's UnitOfWorkScope which wraps nHibernate ISession functionality. Our goal is to eager-load complex properties on demand vs. always eagerly loading them via configuration. The idea is that a given service that retrieves an entity can be customized a bit by the calling code - sometimes we want only the parent entity to be hydrated, other times we may want the complex child properties hydrated, too. To accomplish this, we're doing the following: var iSession = unitOfWorkScope

问题 I am creating data model for two objects Employee and Department. Employee has a list of departments and Department has a list of employees. class Employee{ private IList<Department> _departments; public Employee() { _departments = new List<Department>(); } public virtual ReadOnlyCollection<Department> Departments{ get {return new ReadOnlyCollection<Department>(_departments);} } } class Department{ private IList<Employee> _employees; public Department() { _departments = new List<Employee>();

问题 I have a problem mapping an Id. The structures of the entities are as follows: public abstract class Entity<TEntity, TId> where TEntity : Entity<TEntity, TId> { public virtual TId Id { get; protected set; } public override bool Equals(object obj)... ... } public class EntityA<EntityA, long> : Entity<EntityA, long> { public virtual EntityB B { get; private set; } /* ... */ } public class EntityB<EntityA, long> : Entity<EntityB, long> { /* ... */ } In my model, every EntityA must contain

问题 I have an InvoiceInputModel with a ProjectId property which is a reference to a Project entity. Ideally, I want AutoMapper to be able to map an entire Invoice entity from an InvoiceInputModel , which looks like this: public class InvoiceInputModel { public Guid Id { get; set; } public DateTime Date { get; set; } public string Reference { get; set; } public Guid ProjectId { get; set; } } Obviously the following is bad: Mapper.CreateMap<InvoiceInputModel, Invoice>() .ForMember(src => src

问题 I have the following classes that I need NHibernate to play nicely with. How do I do it? public class Customer { public int ID { get; set; } public string Name {get;set;} } public class Product { public int ID { get; set; } public string Name {get;set;} } public class CustomerPricing { public int ID { get; set; } public decimal Price {get;set;} public Customer Customer { get; set; } public Product Product {get;set;} public datetime ExpiresOn { get; set; } public string ApprovedBy {get;set;} }

问题 I would like to be able to add a collection of Notes to any of my main entities in my NHibernate application. I can see how you could do this with a seperate junction table per entity. However, I would like to be able to avoid this and only have one junction table - if this is possible. Below is the code so far, however this will result in all Notes being loaded for every Entity and I only want to load the notes for that particular entity. What are the alternative approaches I need to take?

问题 Working with legacy tables, need to create a CompositeId based on two char(3) fields. Don't see any overloads that make this possible with Fluent. The mapping I'm attempting looks like this: CompositeId() .KeyProperty(x => x.LegacyEntity1Id, "LegacyEntity1Id") .KeyProperty(x => x.LegacyEntity2Id, "LegacyEntity2Id"); Map(x => x.LegacyEntity1Id).CustomSqlType("char(3)"); Map(x => x.LegacyEntity2Id).CustomSqlType("char(3)"); I've also tried: CompositeId() .KeyReference(x => x.LegacyEntity1,

问题 Can one do this on a fluent nhibernate ? When I try to save, I am profiding the profile and the scenario objects and the id's are not null. Nhibernate complains that it can't insurt NULL for ProfileID column. Fluent Nhibernate doesn't know how to get to the Profile.ID ? CompositeId().KeyProperty(x => x.Profile.ID, "ProfileID").KeyProperty(x => x.Scenario.ID, "ScenarioID"); 回答1: You should probably use this instead: CompositeId() .KeyReference(x => x.Profile, "ProfileID") .KeyReference(x => x

问题 How do I map a composite key, if part of it is not mapped in my entity? Example: I have a table ITEMDELIVERY containing the columns: ITEMDELIVERY_ID (PK) DELIVERY_DATE (PK) I have a table ITEMDELIVERYDETAIL containing the columns: ITEMDELIVERYDETAIL_ID (PK) ITEMDELIVERY_ID (FK) PARTITIONDATE (PK, FK) As you can see, there is a composite key in both tables and ITEMDELIVERYDETAIL has a "composite" foreign key to ITEMDELIVERY . There exists no property PartitionDate in my domain model
