Question

I’m trying to link two (and more) models in a CakePHP application.

I have two database tables: clients and notes. I have the following model classes:

<?php
class Client extends AppModel {
    var $name = 'Client';
    var $hasMany = 'Note';
}

And:

<?php
class Note extends AppModel {
    var $name = 'Note';
    var $belongsTo = 'Client';
}

However, I don’t think they’re linking. When I run print_r($this->Client->find()); in a controller I get the following output:

Array
(
    [Client] => Array
        (
            [id] => 1
            [name] => Martin Bean
        )

)

How can I also fetch the associated Note records for each Client?

EDIT: Despite having the above in my model classes, if I place the following in a controller:

$this->Client->Behaviors->attach('Containable');
print_r($this->Client->find('all', array('contain' => 'Note')));

I get the following error message:

Warning (512): Model “Client” is not associated with model “Note” [CORE/cake/libs/model/behaviors/containable.php, line 363]

Have I missed something that isn’t explained in the CakePHP cookbook?

EDIT 2: I don’t know if this is any help; it’s the debug output:

Answer 1

Fixed it! My models’ filenames were incorrect.

Instead of client.php or note.php I had saved them as client_model.php and note_model.php. All works fine now!
