It looks like the same thing as the link Fabio sent, but I don't want
to use an alpha version in my production website. I'll put a little
test case though, just to make sure we're talking about the same
thing:
<class name="Category">
<id name="ID" column="CategoryID" type="Int32" unsaved-value="0"
access="field.pascalcase-underscore">
<generator class="native" />
</id>
<many-to-one name="Template" column="TemplateID" class="Template" /
>
</class>
<class name="Template" discriminator-value="2">
<id name="ID" column="TemplateID" type="Int32" unsaved-value="0"
access="field.pascalcase-underscore">
<generator class="native" />
</id>
<discriminator column="TemplateTypeID"/>
<set name="TemplateItems" access="field.camelcase-underscore"
cascade="all-delete-orphan" inverse="true" lazy="false">
<key column="TemplateID"/>
<one-to-many class="TemplateItem"/>
</set>
</class>
And the code:
TemplateItem ti = new TemplateItem();
Template t = new Template;
t.AddItem(ti);
repo.Create(t);
Category c = new Category();
c.Template = t;
repo.Create(c);
Category c2 = repo.GetById<Category>(c.ID);
// This will cause the repo to load the Template and Template Item,
instead of just accessing the templateID...
Assert.AreEqual(c.Template.ID,c2.Template.ID);
Thanks for all the quick help!
