Okay, so I just couldn't leave this alone :)
I implemented the following, which works and even brings in the
'contain' info. However there is still a small problem...
// books_controller.php view()
$similar = $this->Book->similar_books($genre_id, $limit);
// model book.php
$similarBooks = $this->find('all', array(
'recursive' => 1,
'joins' => array(
array(
'table' => 'books_genres',
'alias' => 'BooksGenre',
'type' => 'inner',
'conditions'=> array('BooksGenre.book_id = Book.id')
),
array(
'table' => 'genres',
'alias' => 'Genre',
'type' => 'inner',
'conditions'=> array(
'Genre.id = BooksGenre.genre_id',
'Genre.id' => $genre_id
)
)
),
'conditions'=> array('Genre.id' => $genre_id),
'contain' => array(
'Author' => array('fields' => array('Author.id',
'Author.slug')),
'Language' => array('fields' => array('Language.id',
'Language.name')),
),
'fields' => array('DISTINCT Book.id', 'Book.slug'),
'limit' => $limit,
'order' => 'RAND()',
));
return $similarBooks;
Although the above works when called from the books_controller.php, I
also wanted to call this from authors view() page.
// authors_controller.php view()
$similar = $this->Author->Book->similar_books($genre_id, $limit);
Everything works except it doesn't collect up the contain info for
'Author' or 'Language'.
Does anyone have any ideas where I might be going wrong?
