Question

I have such mapping for ProductVariant table:

Id(x => x.Id).Nullable();
Map(x => x.IsEnabled);
Map(x => x.ProductVariantName).Length(45);
Map(x => x.Description);
HasMany(x => x.TestCaseOrdered);
Map(x => x.CreatedDate);

And TestCaseOrder class like this one:

 CompositeId().KeyReference(x => x.TestCaseData).KeyReference(x => x.ProductVariant);
 Map(x => x.TestCaseOrder);
 Map(x => x.TestCaseSetName).Length(45);

But NHibernate generates table TestCaseOrder with two ProductVariant columns:

1) ProductVariant with Primary Key and Not Null.

2) ProductVariantId like a foreign key to the ProductVariant table.
They always have the same data

But I need only one field. How can I achieve that?

Answer 1

seems like a conventionmismatch. Specifying HasMany(x => x.TestCaseOrdered).KeyColumn("ProductVariantId"); and
.KeyReference(x => x.ProductVariant, "ProductVariantId"); should solve it
