Add fields while storing objects...

[Russ McClelland]

I'd like to be able to add a couple of fields to an object in the json that is stored by Raven, and then strip them out when reading. Are "transformations" the way to do this? Or is there a better/simpler way?

You can do that using a listener https://ravendb.net/docs/article-page/3.5/Csharp/client-api/listeners/what-are-conversion-listeners-and-how-to-work-with-them

Thanks! That looks like what I needed.

@Russ - regarding stripping them out on read - if your document class doesn't have them they are "gone" from the pov of your code. Was there some other reason to strip them?

Probably not, I just didn't know if they would cause the reader to stop if it encountered a property that wasn't part of the Type being created... What you said makes perfect sense from a backwards compatibility perspective: it would have to ignore those instead of throwing an exception.
