Hi James
Thanks for your suggestion. I tried this and it didn't work. Code
below shows the state of things. It is as though the call to
instance.Key.Column("ParentId"); is not having any effect.
public void Apply(IOneToManyCollectionInstance instance)
{
bool containsGroupId = instance.Key.Columns.Contains
("GroupId"); // true
instance.Key.Column("ParentId");
bool containsParentId = instance.Key.Columns.Contains
("ParentId"); // false
containsGroupId = instance.Key.Columns.Contains
("GroupId"); // true
}
I've got a work around in place, see following code (Add("ParentId")
that does work.
model.ForTypesThatDeriveFrom<Group>(map =>
{
map.Where("IsDeleted=0");
map.Table("Group_");
map.HasMany(x => x.Children)
.Cascade.Delete()
.Inverse()
.Access.CamelCaseField
(Prefix.Underscore)
.KeyColumns.Add("ParentId");
map.References(x => x.Parent);
});
