nhibernate

问题 I'm new to Fluent NHibernate, thus far I managed to get my mapping working except for the inheritance part. Is there anybody who could help me finish the mapping? I have simplified the code as much as possible. Thank you! My database: CREATE TABLE [User] ( UserID INT NOT NULL IDENTITY(1,1), Type CHAR(1) NOT NULL, Email VARCHAR(255) NOT NULL, PRIMARY KEY(UserID) ); CREATE TABLE [Student] ( UserID INT NOT NULL, Firstname VARCHAR(255) NOT NULL, PRIMARY KEY(UserID), FOREIGN KEY(UserID) REFERENCES

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 Has anyone come across a tool to visualize an ActiveRecord / NHibernate entity model? 回答1: The best thing I can think of is generating a class diagram from VisualStudio of your classes .... 回答2: Check out ActiveWriter.

问题 I'm trying to map int IdPost on DTO to Post object on Blog object, based on a rule. I would like to achieve this: BlogDTO.IdPost => Blog.Post Post would be loaded by NHibernate: Session.Load(IdPost) How can I achieve this with AutoMapper? 回答1: You could define AfterMap action to load entities using NHibernate in your mapping definition. I'm using something like this for simmilar purpose: mapperConfiguration.CreateMap<DealerDTO, Model.Entities.Dealer.Dealer>() .AfterMap((src, dst) => { if (src

问题 My main application form (WinForms) has a DataGridView, that uses DataBinding and Fluent NHibernate to display data from a SQLite database. This form is open for the entire time the application is running. For performance reasons, I set the convention DefaultLazy.Always() for all DB access. So far, the only way I've found to make this work is to keep a Session (let's call it MainSession) open all the time for the main form, so NHibernate can lazy load new data as the user navigates with the

问题 My question is similar to this one: Repository pattern and mapping between domain models and Entity Framework. I have done a lot of reading on here about the following: 1) Mapping the ORM directly to the domain model 2) Mapping the ORM to a data model and then mapping the data model to a domain model (and vice versa) I understand the benefits and limitations of both approaches. I also understand the scenarios where one approach is favoured over the other. There are plenty of examples online,
