If I have a pair of tables that have a one-to-one relation between them, how do I control the order in which they are saved (i.e. define which is the parent)?
Currently NHibernate keeps trying to save "Bar" before it has saved "Foo" and thus either fails due to a foreign key violation when using something like "guid.comb" or null key error if using something like "native". The mapping I have so far is listed below, the example source is at http://gist.github.com/285899 <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default- access="property" auto-import="true" default-cascade="none" default- lazy="true"> <class xmlns="urn:nhibernate-mapping-2.2" name="ValueMapping.Foo, ValueMapping, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="`Foo`"> <id name="Id" type="System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Id" /> <generator class="native" /> </id> <one-to-one cascade="all" class="ValueMapping.Bar, ValueMapping, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" constrained="true" foreign-key="none" name="Bar" /> <property name="Name" type="System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Name" /> </property> </class> <class xmlns="urn:nhibernate-mapping-2.2" name="ValueMapping.Bar, ValueMapping, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="`Bar`"> <composite-id mapped="false" unsaved-value="undefined"> <key-many-to-one name="Foo" class="ValueMapping.Foo, ValueMapping, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"> <column name="Foo" /> </key-many-to-one> </composite-id> <property name="Rate" type="System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Rate" /> </property> <property name="Value" type="System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Value" /> </property> </class> </hibernate-mapping> -- You received this message because you are subscribed to the Google Groups "nhusers" group.
