Instance Method Details

#hydra_show_active_fedora_file ⇒ Object

We want to alias the show method for a later use with #show_active_fedora; because we’re adding quite a bit of logic and need a good alias. Why the alias? Because we were using ‘super’ for the show method and that just doesn’t quite work with all of the antics we’re performing.

#show ⇒ Object

Render the 404 page if the file doesn’t exist. Otherwise renders the file.
