我在書籍表和作者表之間建立了一個HABTM關係,並加入了authors_books表。 但是,我找不到在我的視圖中顯示字段firstname,lastname和fullname的解決方案。如何在視圖中顯示HABTM關係的結果?
書型號:
class Book extends AppModel {
var $name = 'Book';
var $hasAndBelongsToMany = array(
'Author' => array(
'className' => 'Author',
'joinTable' => 'authors_books',
'foreignkey' => 'book_id',
'associatioanForeignKey' => 'author_id'
)
);
筆者的模型:
class Author extends AppModel {
var $name = 'Author';
var $virtualFields = array(
'fullname' => "CONCAT(firstname,' ',lastname)"
);
var $fullname = 'fullname';
var $hasAndBelongsToMany = array(
'Book' => array(
'className' => 'Book',
'joinTable' => 'authors_books',
'foreignkey' => 'author_id',
'associatioanForeignKey' => 'book_id'
)
);
books_controller:
function view($id) {
$this->Book->id = $id;
$this->set('book', $this->Book->read());
}
調試($書)我wiev.ctp給這些結果:
Array
(
[Book] => Array
(
[id] => 8
[title] => A Forest of Kings: The Untold Story of the Ancient Maya
)
[Author] => Array
(
[0] => Array
(
[id] => 6
[firstname] => Linda
[lastname] => Schele
[fullname] => Linda Schele
)
[1] => Array
(
[id] => 7
[firstname] => David
[lastname] => Freidel
[fullname] => David Freidel
)
)
)
我相信數組中的[0] [1]索引是問題。 我搜索了這個問題,並找到了關於這個主題的一些文章,但是無法獲得任何解決方案。
任何幫助,非常感謝。我使用CakePHP 1.3.3
感謝
你究竟試過了什麼?這不應該是一個問題。也許你混淆了數組的語法? – geon 2010-09-08 13:13:52
