Assertion Voter Bundle

Usage

Register bundle in kernel

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...
            new Appsco\AssertionVoterBundle\AppscoAssertionVoterBundle(),
        );

        // ...
    }
}

Configure

# app/config/config.yml

appsco_assertion_voter:
    voter_record_provider: appsco.assertion.voter_record_provider.orm # Default Doctrine ORM voter record provider
    voter_factory: appsco.assertion.voter_factory.simple

Use

// Controller

public function fooAction()
{
    // Fetch assertion information from your service
    $info = $this->get('your_info_provider')->getInfo();

    // Resolve roles
    $roles = $this->get('appsco.assertion.role_resolver')->resolve($info);
}

Persistence layer integration

Bundle can be integrated with any persistence layer by implementing your own VoterRecordProviderInterface or by using one already provided in the bundle.

Doctrine Orm Voter Record Provider

1. (required) Create your VoterRecord entity

   In most cases it will look like this:

   <?php
   
   namespace Acme\YourBundle\Entity;
   
   use Appsco\AssertionVoterBundle\Entity\VoterRecord as BaseVoterRecord;
   use Doctrine\ORM\Mapping as ORM;
   
   /**
    * @ORM\Entity
    */
   class VoterRecord extends BaseVoterRecord
   {
       /**
        * @ORM\Id
        * @ORM\GeneratedValue
        * @ORM\Column(type="integer")
        * @var int
        */
       private $id;
   
       /**
        * @return int
        */
       public function getId()
       {
           return $this->id;
       }
   }

2. (required) Instruct bundle to use it

   Set voter_record_provider in app/config/config.yml to appsco.assertion.voter_record_provider.orm

   Set voter_record_class in app/config/config.yml to your voter record class name.

   Example:

   # app/config/config.yml
   appsco_assertion_voter:
       voter_record_provider: appsco.assertion.voter_record_provider.orm
       voter_record_class: Acme\YourBundle\Entity\VoterRecord

Doctrine Dbal Voter Record Provider

1. (required) Instruct bundle to use it

   Set voter_record_provider in app/config/config.yml to appsco.assertion.voter_record_provider.dbal

   Example:

   # app/config/config.yml
   appsco_assertion_voter:
       voter_record_provider: appsco.assertion.voter_record_provider.dbal

2. (optional) Customize table name and fields

   By default it will try to fetch voter records from VoterRecord table and read the following columns: issuer, attribute, value, role

   You can customize each of these settings by setting container parameters:

   Table name      : appsco.assertion.voter_record_provider.dbal.table_name
   Issuer column   : appsco.assertion.voter_record_provider.dbal.issuer_column
   Attribute column: appsco.assertion.voter_record_provider.dbal.attribute_column
   Value column    : appsco.assertion.voter_record_provider.dbal.value_column
   Role column     : appsco.assertion.voter_record_provider.dbal.role_column: role

Using custom Voter Record Provider

If you're using other persistence layer you can easily integrate bundle with it.

1. (required) Create provider service

   Create your own service which implements Appsco\AssertionVoterBundle\VoterRecordProvider\VoterRecordProviderInterface and register it within container.

2. (required) Instruct bundle to use it

   Set voter_record_provider in app/config/config.yml to your.assertion_voter.record_provider.service_key

Decision Makers

Sometimes, you might want to do more complex decision making, eg. disable editing roles if user has no ROLE_ENABLED etc. To do this you need more than just a set of simple vote records.

You need to implement your own decision maker. Make a service which implements BWC\Component\AssertionVoter\DecisionMakerInterface and tag it:

my.custom.assertion.decision_maker:
    class: My\Custom\DecisionMakerServiceClass
    tags:
        - { name: appsco.assertion.decision_maker, alias: my_decision_maker }

And now you can run assertions against it:

public function fooAction()
{
    // Fetch assertion information from your service
    $info = $this->get('your_info_provider')->getInfo();

    // Resolve roles
    $roles = $this->get('appsco.assertion.role_resolver')->resolve($info, 'my_decision_maker');
}

Note second parameter in RoleResolver::resolve method. It must match alias from appsco.assertion.decision_maker class.
