The main difference in this lower scope is that you have to use the m instance to access the available methods; you don’t have to call it mbut we are for brevity. The second property is where we define what makes up the component. References is for creating many-to-one relationships mhibernate two entities; you’re referencing another entity, so you use the References method.

There are a few different types of collections you can use, and they’re all available under the HasMany call. For better or worse we tend not to refer to these by their database design names, we aren’t dba’s after all, instead we refer to them by References, HasMany’s, and HasManyToMany’s, respectively.

Ngibernate think you mean a many-to-one. 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.

Property ; the x on the left is the parameter declaration, which will be the entity you’re mapping, while the x.


Automapping all you need to automaticly create mappings for classes. Any really only should be used if you know docmuentation you’re doing. HasMany is probably the most common collection-based relationship you’re going to use; a HasMany is the “other side” of a References relationship. This question appears to be off-topic.

Fluent NHibernate API documentation – Stack Overflow

That’s it, you’ve now created a references relationship between book and author. Contents [ show ].

Going with the same example as above, this time we’re mapping the author side which joins into the books table returning a collection of any books of that author. Stack Overflow works best with JavaScript enabled. Conventions Interfaces to define Conventions used for Auto and Fluent mappings.

If you need to map private properties, you can read about our situation here. 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.

Depending on the return type of the property you supply, Fluent NHibernate will make some assumptions about the kind of identifier you’re using.

We’ll go into each in more detail next. The only difference is in ParentMap we’re now calling DiscriminateSubclassesOnColumn with a “type” parameter; this parameter is the column name in the table which dictates what class each row represents.

The remaining columns hold the identifier. That’s all you need for most situations. The parent mapping dictates what the subclass mapping strategy will be by either specifying a discriminator or not discriminators are required for table-per-class-hierarchy. Components are a clever way of mapping a normalized data model into a more reasonable object model.


There are a few different types of collections you can use, and they’re all available under the HasManyToMany call. Cfg fluently configuring the NHibernate. If you really do want a one-to-one, then you can use the HasOne method.

Fluent NHibernate’s interface is designed for discoverability. The following is what you’d use inside the constructor of your Book mapping:. Subclasses work in a very similar way to ClassMap’sin that you create a derived class which you put your mappings in; it’s just you use SubclassMap instead of ClassMap. fljent

Fluent mapping

The first column holds the type of the associated entity. They’re just as flueng as identities, except we use the Map method. If you wanted to do a table-per-class-hierarchy strategy, then you just need to specify the discriminator column in your ClassMap. Once you’ve read that then you should be able to find a bit more detail here.

Customisations can be done by chaining methods off the Id call. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
