Resource nested in multiple other resources

I was wondering how one would approach writing a controller for a resource that is nested in 2 or more other resources, where the view and behavior change (albeit slightly) depending on who the parent resource is.

For example: /authors/1/books /publishers/1/books /owners/1/books

Is there a DRY way to handle this without using a bunch of case statements?

Would it make much difference if there was a need to access the nested resource directly as well: /books

One way that I've thought about but haven't fully fleshed out is using defining a class BooksController and then define child classes like AuthorBooksContoller < BooksController and using inheritance to handle the common methods. How would this work out in the views? Am I approaching this all wrong?

Mark,

You could have a filter in the books_controller to pick out any author_id, publisher_id, etc. and scope the Book.find(...) according to these params. That should be simple and DRY.

Hope this helps.
