Is there a way to get a reference to NHibernate Configuration at the runtime? I need it for SchemaExport(). Update: I am using StructureMap with FluentNHibernate to set it up, but I just want to know if I can get it from SessionFactory or some other object, after SessionFactory has been initialized, without having to rewrite setup in i...
How can I rewrite following so that I can do ObjectFactory.GetNamedInstance("MyNHConfiguration") at later time. "Configuration" is in the variable "cfg" under ExposeConfiguration lambda ForRequestedType<ISessionFactory>() .CacheBy(InstanceScope.Singleton) .AddInstances(x => x.ConstructedBy(() => ...
Why don't I have any class mappings after calling Configuration.Configure()? Here is my class mapping file Category.hbm.xml for BudgetModel.Category: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="BudgetModel" namespace="BudgetModel"> <class name="Category" table="Categories">...
Hopefully, this fictitious example will illustrate my problem: Suppose you are writing a system which tracks complaints for a software product, as well as many other attributes about the product. In this case the SoftwareProduct is our aggregate root and Complaints are entities that only can exist as a child of the product. In other w...
I am using the Table Per Subclass strategy to persist an inheritance heirarchy: I am running into some confusion as to how to map the Debit class, which implements 2 interfaces. I may be overthinking it; I'm still learning NH. Thanks for any input. EDIT What's confusing me is that the only properties that my concrete classes have, th...
Dear ladies and sirs. Suppose I wish to inherit PersistentGenericBag, so that the actual type of my collection property is my custom type, which derives from PersistentGenericBag. I see two possible ways to achieve this: Introduce a new XML keyword, like mybag and somehow register my collection type with NHibernate to associated it w...
I have entities Post and Tag, where there is a many-to-many relationship between the two (e.g. each post can have one or more tags, and each tag can be associated with any number of posts). What I would like to achieve is to have the Tag entity to have a field providing the number of posts which are associated with that tag. However, I ...
I've come up against a problem in converting my Fluent NH mapping to Sharp Architecture. I like the platform for it's ease, however it seems to handle entity mappings slightly differently to pure Fluent NH. I have a Entity 'Category' that is a simple tree structure. I have to override the auto-mapping as there is a M:M property that I ...

I just started thinking about using the NHibernate second level cache in one of my apps. I would probably use the NHibernate.Caches.SysCache.SysCacheProvider which relies on ASP.net cache. Enabling the cache was not a problem, but I am wondering on how to manage the cache e. g. programmatically removing certain entities from the cache e...
