I have 2 tables books and authors, one join table authors_books.
books and author tables have a primary key called id and other info
fields.
Join table has one pk called id and two fk called book_id and
author_id.
Book model is something like that:
<?php
class Book extends AppModel{
var $name = 'Book';
var $hasAndBelongsToMany = 'Author';
?>
and Author model is pretty similar:
<?php
class Author extends AppModel{
var $name = 'Author';
var $hasAndBelongsToMany = 'Book';
?>
I have function called add() in books_controller.php:
function add() {
if (!empty($this->data)) {
if ($this->Book->save($this->data)) {
$this->Session->setFlash('Your book has been
saved.');
$this->redirect(array('action' => 'index'));
}
else
{
$this->Session->setFlash("An error has occured,
check all form
fields.");
}
}
}
and I have a form in the view:
<?php
echo $form->create('Book');
// error instruction
echo $form->input('author', array('type' => 'text', 'label' =>
'Author name:' ));
echo $form->input('title', array('type' => 'text', 'label' => 'Book
title:' ));
echo $form->end('Save Album');
?>
When I send this form, only books table is filled with data (e.g.
Title is inserted correctly in books table). authors and authors_books
tables are not filled with any data.
Why? Where I wrong, i've followed all naming convention (I suppose).
