Instantiate model with columns

How can I instantiate a model and get all columns already declared in the instance?

$modelA = User::findFirst();
echo $modelA->id; //OK
$modelB = new User();
echo $modelA->id; //Id is undeclared causing errors instead of returning blank

Currently I need to declare by hand the model columns in the event onConstruct but I want to make use of the database introspection strategy and get properties declared from the table schema schema when I use new User();.

Anyone knows something that can help me out?!

Try the Annotations Strategy mentioned on that page.

So, something like

class Test extends \Phalcon\Mvc\Model
{

    /**
     * @Primary
     * @Identity
     * @Column(type="integer", nullable=false)
     */
    public $id;
...


Get an instance of the meta-data adapter from the services container:

<?php

use Phalcon\Mvc\Model\MetaData\Apc as ApcMetaData,
Phalcon\Mvc\Model\MetaData\Strategy\Annotations as StrategyAnnotations;

$di['modelsMetadata'] = function() {

    // Instantiate a meta-data adapter
    $metaData = new ApcMetaData(array(
        "lifetime" => 86400,
        "prefix"   => "my-prefix"
    ));


Get the columns for your model like so:

<?php

$test = new Test();

// Get Phalcon\Mvc\Model\Metadata instance
$metaData = $test->getModelsMetaData();

// Get fields names
$attributes = $metaData->getAttributes($test);
print_r($attributes);

// Get fields data types
$dataTypes = $metaData->getDataTypes($test);
print_r($dataTypes);


All of the above can be found in the link.

Also check out the MetaData APIs.

Hope that helps.
