For example I have a Book model, and the first column defined in the

BUT when I display the list of books, I see the titles displayed.
This is fine, but I'm not sure how this happened.
The default card tag looks for a name attribute on the model.
Obviously, Book doesn't have one of those - but the name_attribute
function tries some other likely candidates ('title' is the only other
one presently).
You can explicitly specify an attribute to be used in this fashion by
adding :name => true to the declaration of the field in the model.
As to the card, I'd check out the cookbook which should have some info
on customizing the <card> tag. If you're just interested in having
"Author - Title" instead of just "Title" in the links, one quick way
would be (in book.rb):
def title_and_author
"#{author.name} - #{title}"
end
self.name_attribute = 'title_and_author'
