I have an existing web application that I am converting to use CakePHP. The problem is that the primary keys for most of the tables are in this format "${table_name}_id" (story_id) instead of the CakePHP way of 'id'
When ever I try to update some of the fields for a row in the story table, the Save() function will return false. Is there any way of getting a more detailed error report from the Save() function. ?
When I set Configure::write('debug', 2);
in core.php
and check the SQL statements I do not see any UPDATE command, only SELECT statements.
I tried to edit the controller adding the following line to manually set the id field for the controller but it did not help.
$this->Story->id = $this->data['Story']['story_id'] ;
I'm running out of ideas. Any suggestions?
I have included the source code that I am using below
Story controller:
function admin_edit($id = null)
{
if (!$id && empty($this->data)) {
$this->Session->setFlash(__('Invalid '. Configure::read('Site.media') , true));
$this->redirect(array('action'=>'index'));
}
$this->layout = 'admin';
if (!empty($this->data)) {
if ($this->Story->save($this->data)) {
$this->Session->setFlash(__('The '. Configure::read('Site.media') .' has been saved', true));
} else {
$this->Session->setFlash(__('The '. Configure::read('Site.media') .' could not be saved. Please, try again.', true));
}
}
$this->data = $this->Story->read(null, $id );
}
Story model:
class Story extends AppModel {
var $name = 'Story';
var $primaryKey = 'story_id';
var $validate = array(
'author_id' => array('numeric'),
'title' => array('notempty'),
'story' => array('notempty'),
'genra' => array('notempty'),
'form' => array('notempty'),
'wordcount' => array('Please enter a number between 1 and 1000' => array(
'rule' => array('range', 1, 1001),
'message' => 'Please enter a number between 1 and 1000' ),
'Required' => array( 'rule' => 'numeric', 'required' => true )
)
);
//The Associations below have been created with all possible keys, those that are not needed can be removed
var $belongsTo = array(
'Author' => array(
'className' => 'Author',
'foreignKey' => 'author_id'
)
);
var $hasMany = array(
'UserNote' => array(
'className' => 'UserNote',
'foreignKey' => 'story_id',
'dependent' => false,
'conditions' => 'UserNote.notes != ""'
)
);
}
Story view:
echo $form->create('Story', array('action' => 'edit' ) );
echo $form->input('story_id',array('type'=>'hidden') );
echo $form->input('title');
echo $form->input('story');
echo $form->input('bio' );
echo $form->end('Update story details');?>
Story table

`story_id` int(11) NOT NULL AUTO_INCREMENT,

You should manually override the primary key field in the model (which is the right place to do this - the name of a primary key field is an attribute of the model, and not something that should be 'fudged' around in the controller.)
class Example extends AppModel { var $primaryKey = 'example_id'; // example_id is the field name in the database}
The above code is from http://book.cakephp.org/view/437/primaryKey
While the suggestion to turn off validation will work, it's not the right way to go about it.
Lastly, if you're setting model variables within a controller, you use $this->Model->set('attributeName',value) rather than $this->Model->attributeName
