nhibernate映射从流畅到映射的代码

Question

One Country has many States . One State belongs to one Country. Mapping Country property in StateMap using fluent mapping was

public StateMap()
{
    ...
    References(m => m.Country).Not.Nullable();
}

what is nhibernate mapping by code alternative

should I simply map Country as property

Property(m => m.Country});

Answer 1

The alternative to References is Mapping-by-Code - ManyToOne

ManyToOne(x => x.Country, m =>
{
    m.Column("column_country");
    // or...
    m.Column(c =>
    {
        c.Name("column_country");
        // other standard column options
    });
...

The HasMany is Mapping-by-Code - Set and Bag

Set(x => x.States, c =>
{ 
    c.Lazy(CollectionLazy.Lazy); // or CollectionLazy.NoLazy, CollectionLazy.Extra

    c.Table("tableName");
    c.Schema("schemaName");
    c.BatchSize(100);
    ...
