Mapping nested components in Fluent NHibernate

fluent-nhibernate, nhibernate, nhibernate-mapping, orm

Solution

Ah, Jimmy Bogard from the FNH mailing list showed me - it's quite straightforward. I don't know what I was doing before! Anyway, for anyone else who's interested:

Component(c => c.Address, m =>
{
    m.Component(cp => cp.Country, m2 =>
    {
        m2.Map(x => x.Name); //etc
    }

Problem

I have a 'User' Entity that contains an 'Address' Value Object. I have this mapping ok using FNH's Component concept. However, the Address VO also contains a Country which is another value object. I had assumed that this should be just nested as another component, but this doesn't seem to work. Can anyone tell me how I should solve this? Code for mapping is below... Thanks! ``` public UserMapping() { Table("Users"); Id(c => c.Id).GeneratedBy.HiLo("100"); Map(c => c.UserName).Not.Nullable().Length(64); Map(c => c.Email).Not.Nullable().Length(128); Map(c => c.Password).Not.Nullable().Length(256); Map(c => c.Roles).Length(64); Map(c => c.FirstName).Not.Nullable().Length(64); Map(c => c.LastName).Not.Nullable().Length(64); Map(c => c.BirthDate).Not.Nullable(); //Address Component(x => x.Address, m => { m.Map(x => x.AddressLine1).Not.Nullable(); m.Map(x => x.AddressLine2); m.Map(x => x.City).Not.Nullable(); m.Map(x => x.Region); m.Map(x => x.PostalCode).Not.Nullable(); //*****Country Here******** // country has Name and Code }); } ```
