问题 According to the REST philosophy, a PUT request should update the resource at a URL if it exists, and create it if it doesn't exist. So in other words, if I use the following URL: PUT http://server/item/5 If an Item exists with an ID of 5, it will be updated. If an Item doesn't exist with an ID of 5, a new Item will be created with an ID of 5. However, I'm using NHibernate for persistence, and I mapped my IDs as Identity . This means that no matter what value I assign the ID, NHibernate will

问题 I’m trying to develop some basic web app. I will post question with only two entities Article and Image. One article has many images, and one or more images belong to only one article. Every article implements interface IArticle and abstract class ArticleBase. ArticleBase defines only common properties for each article but child articles can have more properties beside those defined in ArticleBase. So I have ( IArticle , ArticleBase , ArticleComputer , ArticleCar ) public abstract class

问题 I'm looking for a FluentNH (Fluent NHibernate) convention or configuration that ignores all properties that have no setter: It would still map these: public class foo{ public virtual int bar {get; private set;} } And omit these: public class foo{ public virtual int fizz{get;private set;} public virtual int bar{get {return fizz;}} //<------- } 回答1: You should use a custom mapping configuration public class DefaultMappingConfiguration : DefaultAutomappingConfiguration { public override bool

问题 I have a class with a field: protected DateTime insertDate; This is mapping for this fiels: <property name="InsertDate" access="field.camelcase" update="false" /> This field is set when with ctor public DocuBase(DateTime insertDate) and is persisted only when row is added to the database. I don't need property for it at all, no setter & no getter. I worked in NHibernate 3. And now, I've moved from NHiberbate 3 to NHibernate 3.3.1, and I get this exception when session factory is created:

问题 I am trying to use join to pull in a single property from another table, which doesn't have a mapping. My problem is that when I create a new instance of my mapped entity and save it I get an error about trying to insert into my unmapped table (it's trying to insert null into a not null column). I thought using .ReadOnly() would stop nhibernate from trying to insert into my unmapped table but that doesn't seem to work. My mapping looks like this: // Join _UnMapped table with Mapped table to

问题 I'm working with an Oracle DB, and I'm trying to map this class: public class Book { public virtual int Id { get; private set; } public virtual string Author { get; set; } public virtual string Title { get; set; } public virtual string Text { get; set; } } With this mapping class: public class BookMap : ClassMap<Book> { public BookMap() { Id(x => x.Id); Map(x => x.Author); Map(x => x.Title); Map(x => x.Text); } } But the column type that it generates me is NVARCHAR(255), And the Book.Text

问题 We have POCO, something like: public class Person { public Guid PersonID { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public DateTime DateOfBirth { get; set; } public string Version {get; set; } } And the corresponding hbm file as <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="NHibernate.FirstAttempt" namespace="NHibernate.FirstAttempt.Entity" > <class name="Person" lazy="false"> <id name=
