Can you do anything useful with the Captionfile class? Creating
records for example.

I assume you have you tried restarting the server.

Are you sure you have not got Captionfile declared in another file
somewhere? Perhaps you kept a copy of captionfiles.rb with an out of
date definition in it. Do a global source search for Captionfile in
your project.

That should be has_many :runs by the way (plural) but I don't think
that is anything to do with this problem.
