FLUENT NHIBERNATE DOCUMENTATION PDF
Contribute to FluentNHibernate/fluent-nhibernate development by creating an read through our API documentation, or just see what’s available for reading in. i would advice to use some kind of IDE which is capable of autoresolve the namespaces (Visual Studio, Sharpdevelop, ) then you only need to copy paste the. Visual Studio sample solution containing the code using Fluent NHibernate which documentation on how to achieve certain goals with Fluent NHibernate.

This type of mapping always requires more than one column. Going with the same example as above, nhibernxte time we’re mapping the author side which joins into the books table returning a collection of any books of that author.
There are numerous customisations available through methods chained from the Map call. Every mapping requires an Id of some kind, these are mapped using the Id method; this method takes a lambda expression of the property you want to use as your Id. Table-per-subclass is the default mapping for subclasses, so unless you say otherwise you’ll have a separate table per-subclass.
That’s all there is to it, parent and child are now mapped as subclasses. For example, if we were to need to change what column the property maps to we could use the Column method, or for explicitly specifying the identity generator you could use the GeneratedBy property. I have been using Reflector to find things and it works, but it is not ideal. The first column holds the type of the associated entity.
For example, if your Id property is an intthen we assume you’re using an identity column; similarly, if you use a Guid then we assume it’s a Guid Comb. They’re just as simple as identities, except we use the Map method. Mapping contains classes used to create Fluent Mappings. You’ll quickly get used to these lambdas, as they’re used everywhere in Fluent NHibernate.
The second property is where we define what makes up the component.

If you wanted to do a table-per-class-hierarchy strategy, then you just need to specify the discriminator column in your ClassMap. Depending on the return type of the property you supply, Fluent NHibernate will make some fluetn about the kind of identifier you’re using.
To quote the NHibernate documentation:.
You should use this only in very special cases eg. Customisations can be done by chaining methods off the Id call.

Automapping all you need to automaticly create mappings for classes. How could I have possibly used VS as long as I have and never noticed its namespace resolution support?
Documentatoon [ show ]. For example, if you’re generating your schema you may want to specify whether the column itself is nullable, you can do that by using the Nullable method and optionally the Not operator property.
Can anyone either confirm that I need to generate my own after building the source or point me to somewhere I have missed? We’ll go into each in more detail next. There are two strategies for mapping inheritance hierarchies in Fluent NHibernate, table-per-class-hierarchy and table-per-subclass; the former being a subclass, and the latter a joined-subclass.
Fluent mapping is the nhibfrnate mapping style that Fluent NHibernate uses.
Components are a clever way of mapping a normalized data model into a more reasonable object model. In this example we’re specifying that the Nyibernate property is mapped to a PersonId column in the database, and it’s using an assigned generator. The parent nhlbernate dictates what the subclass mapping strategy will be by either specifying a discriminator or not discriminators are required for table-per-class-hierarchy.
There are a few different types of collections you can use, and they’re all available under the HasMany call.
