Hi,
Thanks I noticed the typo myself. Now it seems to work for the last
object that has a reference to the city (here it is ok to delete the
‘last city’) but not for any objects ‘before’. I get an exception that
the city cannot be found although it definitely exist.
Here are some fractions of my mapping file:
...
<joined-subclass
name="Address" table="Addresses" dynamic-update="true">
<key foreign-key="ItemIdAddress" column="AddressId"></key>
...
<many-to-one name="City" class="City" column="CityId" cascade="delete-
orphan" />
...
</joined-subclass>
...
<class name="City" table="Cities">
<id name="CityId" unsaved-value="0">
<column name="CityId" sql-type="bigint"/>
<generator class="identity" />
</id>
<property name="CityName" >
<column name="CityName" not-null="true" sql-type="char(100)"/>
</property>
</class>
I am using generic DAOs for all my classes. This is the code for
deletion:
...
public void MakeTransient(T entity)
{
Session.Delete(entity);
Session.Flush();
}
...
Looking forward to hearing from you.
BTW is there a good book/paper/etc. with examples of more complicated
scenarios of modelling and implementing different relationships plus
DAO code exacmples. I have NHibernate in Action which only seems to
touch the surface.
Thanks.
Christian
