Question

I’m so surprise while I’m working in Fluent NHibernate. I got my legacy database that has primary key column name is different from my property in domain model. I’m sure that I can use this mapping file:

<class name='Person'>   <id name='Id' column='CommentId'>       <generator class='native'/>   </id>   <property name='Description' type='String' /> </class> 

But how I really get this mapping in Fluent NHibernate mapping?

Answer 1

The following Fluent-NHibernate mapping:

public class PersonMap : ClassMap<Person> {     public PersonMap()     {         Id(x => x.Id, 'CommentId')             .GeneratedBy.Native();          Map(x => x.Description);     } } 

generates this XML mapping:

  <class name='Person' table='[Person]' xmlns='urn:nhibernate-mapping-2.2'>     <id name='Id' column='CommentId' type='Int32'>       <generator class='native' />     </id>     <property name='Description' column='Description' length='100' type='String'>       <column name='Description' />     </property>   </class>
