Question

I am following the http://wiki.fluentnhibernate.org/Getting_started tutorial to create my first NHibernate project with Fluent NHibernate

I have 2 tables

1) Account with fields

Id
AccountHolderName
AccountTypeId

2) AccountType with fields

Id
AccountTypeName

Right now the account types can be Savings or Current
So the table AccountTypes stores 2 rows
1 – Savings
2 – Current

For AccoutType table I have defined enum

public enum AccountType {
    Savings=1,
    Current=2
}

For Account table I define the entity class

public class Account {
    public virtual int Id {get; private set;}
    public virtual string AccountHolderName {get; set;}
    public virtual string AccountType {get; set;}
}

The fluent nhibernate mappings are:

public AgencyMap() {
    Id(o => o.Id);
    Map(o => o.AccountHolderName);
    Map(o => o.AccountType);
}

When I try to run the solution, it gives an exception – InnerException = {“(XmlDocument)(2,4): XML validation error: The element ‘class’ in namespace ‘urn:nhibernate-mapping-2.2’ has incomplete content. List of possible elements expected: ‘meta, subselect, cache, synchronize, comment, tuplizer, id, composite-id’ in namespace ‘ur…

I guess that is because I have not speciofied any mapping for AccountType.

The questions are:

1. How can I use AccountType enum
   instead of a AccountType class?
2. Maybe I am going on wrong track. Is there a better way to do this?

Thanks!

The following apparently no longer works https://stackoverflow.com/a/503327/189412

How about just doing this:

public AgencyMap() {
    Id(o => o.Id);
    Map(o => o.AccountHolderName);
    Map(o => o.AccountType).CustomType<AccountType>();
}

The custom type handles everything 🙂
