Hmmm, maybe I'm thinking about this all wrong. It seems like its grown
into an even bigger issue now.
If I try to access a nested route from it's parent resource, I cant.
I'll give you an example:
If I try to use <%= link_to book_pages_path %> from a page with the
URL of "books/1", I get an error saying:
book_pages_url failed to generate from
{:action=>"index", :controller=>"pages"} - you may have ambiguous
routes, or you may need to supply additional parameters for this
route. content_url has the following required parameters:
["books", :book_id, "pages"] - are they all satisfied?
I just don't get it...how am I supposed to create a link for users to
go view ALL the pages for a specific book?
