I'm trying to find a way to localize entity properties in NHibernate that fits an existing schema.
I've been through the forums / stackoverflow etc so not trying to start a debate on localization
I've got very close to something I'm happy with. I end up with a fluent mapping that looks like
HasMany(p => p.LocalisedValues).KeyColumn("AKeyColumn").ApplyFilter<LocaleFilter>("LocaleId = :localeId").Cache.Region("Test").ReadOnly();
where LocalisedValues is a collection of object that has a property for each property of the entity I want to localize.
I can set the filter immediately after creation of the session and it all works very nicely until I look at the caching.
Looking through the debug logs I get "Refusing to add to cache due to enabled filters" and looking at the source I can see why that is.
My questions are
1. Are filters the only way I can reduce the LocalisedValues collection to just the values for the current locale?
2. I see that the message about caching comes directly from hibernate. If I wanted to have a go at implementing caching for filters what process should I follow?
Is nHibernate just a straight port of hibernate or do its features diverge?
