    I'm in the process of learning how to get a list of books by an author in the booklink tutorial.

    I'm at the point where I'm adding a finder for books into the author 'show' action in the author controller.

    I have it working, courtesy of an example in another forum post. The line I added to the controller was:

    $this->authors = $this->Author->find(@$this->params['id'], array('include' => 'books'));

    But, I'm confused (and curious) about why we are assigning to $this->authors (plural) whereas in the book controller,
    when we added the finder for authors, we added the line:

    $this->book = $this->Book->find(@$this->params['id'], array('include' => array('main_author', 'co_author')));

    where $this->book is singular.

    Moreover, in the show view, both references are (as i would expect) singular...

    link_to($text_helper->translate('Edit this Book'), array('action' => 'edit', 'id'=>$book->getId()))
    link_to($text_helper->translate('Edit this Author'), array('action' => 'edit', 'id'=>$author->getId()))

    Can someone please explain this for me?

    many thanks,

    the thing is you can assign the result of a find to whatever you want, but for example in listing they assigned it to some plural variable because in the view there is this:

     {loop authors}

    and that do this:

     foreach($authors as $author)

    so when you use the sintax of "loop", the framework singularize the given word. and then is accessed (in singular of course) like {author.name} or $author->something. but in the show is only one object so there is no loop, and consenquently innecessary to use a plurar.

    so finally i would say that you only use plurals because you want it to work with "loop".

    Hi Insanet,

    Many thanks for your reply, that explains it perfectly.

    Btw, how do you get the yellow highlighted code into your comments? I can't seem to find any instructions for the forum on how to do that .

    first i press "markdown" button in the form, then whatever you type that starts with 4 spaces and is in a newline, is formatted. you also need a empty line above the line your writing but this is only need once for each block. you can practice with the preview post also.
