Hi!

I have a derived read only property in a class that I want NHibernate to insert/update to the database, but I don't want NHibernate to set the property when the object is initialized since the property is set internally by the class when another property is set.

Is there a way to do this, other than modifying the domain model?

I have looked at IInterceptor and IUserType but haven't found a way.

Help would be very much appreciated.

Maybe I get you wrong, but if the property setting your read only property is mapped, why do you need to map your read only property at all ? It should be set when the other property is set during object instantiation.


Or you could change the getter of the derived property to get the current value and use an empty setter.

Hi!

You got me right.

Some properties in the class are populated from Active Directory, some from the database. One of the properties taken from AD I also wish to save to the database in order to execute queries with that property/field as a filter.

I've done as you said, I used a (private) empty setter, but I would have preferred to avoid that. If there is no way I can put this logic in the data access layer, no harm is done. This works.

Thanks.

You said you tried the IInterceptor. What was your problem there ? You should be able to change the value there.

But in my opinion that add's unnecessary complexity to your app, anyway.

I stumbled over IPropertyAccessor while searching the documentation for something else. Seems that you can implement your own access strategy. Maybe you can suppress the "select" there.

Hi!

It would work with IInterceptor, but with my current design I would have to access the AD twice. I will have a look at IPropertyAccessor or maybe I will have to rethink my design and use IInterceptor only to get data from AD.

Thank you very much for your help and time. It's very much appreciated.
