Attachment_fu with fixtures

Dear list,

I can’t figure out how to use fixtures with attachment_fu. I know how
to use files with RSpec in my controllers,
BackgroundPhoto.create(:uploaded_data => fixture_file_upload(“files/”, “application/x-zip”)), but this does not work with
fixtures(obviously). More importantly I have no idea where to start…
Can someone shed some light on this?

With kind regards,
