Pomm compilation target for RulerZ

Pomm compilation target for RulerZ.

Usage

Pomm is one of the targets supported by RulerZ.

This cookbook will show you how to retrieve objects using Pomm and RulerZ.

Here is a summary of what you will have to do:

• configure Pomm;
• configure RulerZ;
• filter your target.

Configure Pomm

This subject won't be directly treated here. You can either follow the official documentation or use a bundle/module/whatever the framework you're using promotes.

Configure RulerZ

Once Pomm is installed and configured we can the RulerZ engine:

$rulerz = new RulerZ(
    $compiler, [
        new \RulerZ\Pomm\Target\Pomm(), // this line is Pomm-specific
        // other compilation targets...
    ]
);

The only Pomm-related configuration is the Pomm target being added to the list of the known compilation targets.

Filter your target

Now that both Pomm and RulerZ are ready, you can use them to retrieve data.

The Pomm instance that we previously injected into the RulerZ engine only knows how to use PommProject\ModelManager\Model\Model so the first step is to access the model to query:

$playerModel = $pomm['my_db']->getModel('\MyDb\PublicSchema\PlayerModel');

And as usual, we call RulerZ with our target (the Model object) and our rule. RulerZ will build the right executor for the given target and use it to filter the data, or in our case to retrieve data from a database.

$rule  = 'gender = :gender and points > :points';
$parameters = [
    'points' => 30,
    'gender' => 'M',
];

var_dump(
    iterator_to_array($rulerz->filter($playerModel, $rule, $parameters))
);

That's it!
