What does your full SubtitleFile class look like? It looks like there is an issue with how the #subtitles method is storing information. Since you're using ActiveRecord::BaseWithoutTable there are probably not going to be any unique primary keys amongst your SubtitleFiles to help differentiate them. So if #subtitles is a has_many, every call to SubtitleFile#subtitles may lookup Subtitles in the exact same way w/o any unique key to use to differentiate which subtitles belong to which subtitle files which would produce the results you are seeing. Is Subtitle a ActiveRecord::BaseWithoutTable or a real ActiveRecord::Base model? > > Any idea what's going on? I'd appreciate any help at all.
