Question

just starting with cakephp and almost with php after a few years without use it….

I have a table structure like this:
Parent table…… Clients:

<?php
class Cliente extends AppModel
{
    var $name = 'Cliente';
        var $validate = array(
                            'nombre' => array('rule'=>'notEmpty')
                             );
        var $hasMany = array(
            'Proyecto' => array(
                'className'  => 'Proyecto',
                'foreignKey' => 'cliente_id',
                'order'      => 'Proyecto.nombre ASC',
                'dependent'  => true                
            )
        );
}
?>

And child table: Proyects..
A client can have several projects assigned.

<?php
class Proyecto extends AppModel
{
    var $name = 'Proyecto';
        var $validate = array(
                            'nombre' => array('rule'=>'notEmpty')
                             );
        //var $belongsTo = 'Cliente';
        var $belongsTo = array(
            'Cliente' => array(
                'className' => 'Cliente',
                'foreignKey' => 'cliente_id'
            )
        );
}
?>

Proyects only can be added (INSERT) from the index client view. So, I have this add (anadir) method:

    function anadir($cliente_id, $nombre) {
        if (!empty($this->data)) {
//                        echo "El código de cliente 22222: ". $this->data['Proyecto']['id'] . "</br>";
//                        echo "El código de cliente fk: ". $this->data['Proyecto']['cliente_id'] . "</br>" ;
//                        print_r($this->data);
                        //$this->data['Proyecto']['cliente_id'] = $cliente_id;
            if ($this->Proyecto->save($this->data)) {
                $this->Session->setFlash('El proyecto ha sido grabado.');
                $this->redirect(array('controller'=>'clientes', 'action'=>'listar'));
            }
                } else {  
                        //echo "El código de cliente 11111: ". $this->data['Proyecto']['id'];                  
                    $this->data['Proyecto']['cliente_id'] = $cliente_id; 
                }
                $this->set('idcliente', $cliente_id);
                $this->set('nombrecliente', $nombre);
    }

I can show the parent client (id and number) in the ‘anadir.ctp’ view, but it always update the same proyect, changing the name and description only. No ADD/INSERT is done in the table, only UPDATE.

<!-- File: /app/views/proyectos/anadir.ctp -->  

<h1>A&ntilde;adir proyecto a cliente <?php echo "[$idcliente] - $nombrecliente"; ?></h1>
<?php
    //echo $this->Form->create('Proyecto', array('action' => 'anadir'));
    echo $this->Form->create('Proyecto', array('url' => '/proyectos/anadir/'.$idcliente.'/'.$nombrecliente)); // array('action' => 'anadir'));
    echo $this->Form->input('cliente_id', array('type' => 'hidden'));
    echo $this->Form->input('nombre');
    echo $this->Form->input('descripcion', array('rows' => '10'));
    echo $this->Form->end('Grabar proyecto');
    echo $this->Html->link('Cancelar', array('controller'=>'clientes', 'action'=>'listar'));
?>

Surely it is a newbie question but I have tried almost everything.

Any idea ?

Thanks in advance.

==== Finally ====

After a few days trying to solve this it is running now. But I cannot understand the problem and I have no explanation why I have had that weird problem…

So I am going to look forward symfony2 Perhaps more difficult to start with but I hope more flexible (with multi Primary Keys and foreign key support, mainly) and clear than cakephp.

Answer 1

So it still looks (as deizel suggested) that you’ve got id set in your $this->data somehow, probably a field with mistaken in a form, not sure (you can post your view here so we can take a look). The best way to check it is to monitor actual SQL queries; put this after $this->Model->save() (without adding $this->Model->create()yet, for debug purposes):

$log = $this->Model->getDataSource()->getLog(false, false);
debug($log);

Add output of above to your question.

Regarding $this->Model->create(): calling it prior to $this->Model->save() is perfectly ok and even recommended. It’s like variable initialization – you can skip it, but at your own risk, when you’re absolutely sure what you’re doing.

To address Missing argument 1 for ProyectosController::anadir() error you should post your URL here. It should be something like /proyectos/anadir/2/10.
