Troy,
I think it's very usefull to combine the automapping with custom
mapping to get the best of both worlds. The approach that I'm testing
out is defining your custom mapping as a specialization of an
automap:
eg.
My entity customer:
public class Customer
{
public Guid Id {get;set;}
public string PartyNumber { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
}
My customized Customer AutoMap (which I put in my repository
assembly):
public class CustomerMap : AutoMap<Customer>
{
public CustomerMap()
{
Map(c => c.PartyNumber).TheColumnNameIs("party");
}
}
(AutoMap<T> inherits from ClassMap<T>)
Load the 'customized AutoMap<T>'s first using
model.MergeWithAutoMapsFromAssemblyOf<CustomerMap>(); //model is
AutoPersistenceModel
Maybe this can be of interest to you.
Bart.
