Eloquent compilation target for RulerZ
Eloquent compilation target for RulerZ.
Eloquent ORM is one of the targets supported by RulerZ.
This cookbook will show you how to retrieve objects using Eloquent and RulerZ.
Here is a summary of what you will have to do:
This subject won't be directly treated here. You can either follow the official documentation.
Once Eloquent is installed and configured we can the RulerZ engine:
$rulerz = new RulerZ( $compiler, [ new \RulerZ\Eloquent\Target\Eloquent(), // this line is Eloquent-specific // other compilation targets... ] );
The only Eloquent-related configuration is the
Eloquent target being added to the
list of the known compilation targets.
Now that both Eloquent and RulerZ are ready, you can use them to retrieve data.
Eloquent instance that we previously injected into the RulerZ engine knows
how to use both
instances, so the first step is to create a query builder:
$queryBuilder = User::query(); // where "User" is an Eloquent model
And as usual, we call RulerZ with our target 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($queryBuilder, $rule, $parameters)) );
