FluentNhibernate and References - fluent-nhibernate

Question

I was trying to change a convention so that my IDs follow this simple rule: ProductCode, CustomerCode, OrderCode etc etc.
I've found a simple way to do that adding a convention:
public class PrimaryKeyNameConvention : IIdConvention
{
public void Apply(FluentNHibernate.Conventions.Instances.IIdentityInstance instance)
{
instance.Column(instance.EntityType.Name + "Code");
}
}
Now I've got what I wanted but it seems that FluentNhibernate refuses to apply the same rule with column referencing my primary keys.
EX: my table Customer will have a PK called CustomerCode but my table Order will have a reference column called Customer_Id.
I've tried different ways to rename the column Customer_Id in CustomerCode (table Order) but it seems that nothing works properly.
The only solution which seems to work is adding a convention like this:
public class ReferenceConvention : IReferenceConvention
{
public void Apply(FluentNHibernate.Conventions.Instances.IManyToOneInstance instance)
{
instance.Column(instance.Property.PropertyType.Name + "Code");
}
}
but now FluentNhibernate creates two columns which reference my primary key: CostumerCode and Customer_Id.
I can't figure out what I am doing wrong.
Any help would be apreciated.

Answer 1

Take a look at the ForeignKeyConvention base-class.
The ForeignKeyConvention is an amalgamation of several other conventions to provide an easy way to specify the naming scheme for all foreign-keys in your domain. This is particularly useful because not all the foreign-keys are accessible in the same way, depending on where they are; this convention negates need to know about the underlying structure.

Answer 2

As James suggested I've now applied these two conventions:
public class PrimaryKeyNameConvention : IIdConvention
{
public void Apply(FluentNHibernate.Conventions.Instances.IIdentityInstance instance)
{
instance.Column(instance.EntityType.Name + "Code");
}
}
public class CustomForeignKeyConvention : ForeignKeyConvention
{
protected override string GetKeyName(Member property, Type type)
{
if (property == null)
return (type.Name + "Code"); // many-to-many, one-to-many, join
return (property.Name + "Code"); // many-to-one
}
}
and everything works fine.
