Active Resource and nil

[Henry Maddocks]

I have an ActiveResource call similar to below

@user = User.find(:first, :from => :email, :params => {:email =>
'foo@bar'})

If the find returns nil what is supposed to happen? I'd really like
to get nil to the caller. What's best practice in this case?

Wow, activeresource has really changed since I last looked (before they
pulled it from the 1.2 release)

As far as I can tell from reading (don't have time to mock it up sorry), if
it can't find anything, The server is meant to return a 404 error, which
activeresource interprets as "throw a ResourceNotFound exception"

If that is the case you would have to rescue/return nil wouldn't you?

I'm trying to use dynamic finder on the server side which returns
nil. Guess I have to switch to find with conditions instead.
