Vctls Select2Entity Extension Bundle

This bundle provides helpers for working with Tetranz Select2EntityBundle.

Searcher classes define configuration for the entities used in Select2 fields.

Configuration

Add routing to the default controller:

# routes.yml
vctls_select2_entity_extension:
    resource: '@VctlsSelect2EntityExtensionBundle/Resources/config/routing.yaml'

Add the namespace of your Searcher classes in config.yml. Default is App\Util:

# config.yml
vctls_select2_entity_extension:
    searcher_namespace: 'App\Tools\Select2\'

Creating Select2 fields:

First, create a Searcher class for the entity you want to use in your field.

<?php

namespace App\Util;

use Vctls\Select2EntityExtensionBundle\Util\Searcher;

class ExampleSearcher extends Searcher
{
    public $alias = 'example';
    public $idMethod = 'getId';
    public $textMethod = '__toString';
    public $searchfileds = ['example.name'];
}

Then, add a Select2 field in your form:

<?php

namespace App\Form\Example;

use App\Entity\Example;
use Vctls\Select2EntityExtensionBundle\Util\S2;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;

class ExampleType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        // with the helper class...
        $builder->add(...S2::build('example', Example::class));
        
        // or without it
        $builder->add('example2', Select2EntityType::class, [
            'remote_route' => 'generic_autocomplete',
            'remote_params' => [
                'classname' => Example::class
            ],
            'class' => Example::class,
            'primary_key' => 'id',
            'text_property' => 'name',
            'minimum_input_length' => 2,
            'delay' => 250,
            'cache' => true,
            'placeholder' => 'Select an example',
        ]);
    }
}

Secure access to the default controller

You can create a Voter that will controll access to different entities.

<?php
// App\Security\EntityVoter.php
namespace App\Security;

use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Core\Authorization\Voter\Voter;
use App\Entity;

class EntityVoter extends Voter
{
    const ENTITIES_BY_ROLE = [
        'ROLE_USER' => [
            Entity\Example::class
        ],
        'ROLE_ADMIN' => [
            Entity\User::class
        ]
    ];
    
    protected function supports($access, $subject)
    {
        return $access === 'view' && gettype($subject) === 'string';
    }

    protected function voteOnAttribute($access, $subject, TokenInterface $token)
    {
        $roles = $token->getRoles();

        foreach ($roles as $role) {
            if (in_array($subject, self::ENTITIES_BY_ROLE[$role->getRole()])) {
                return true;
            }
        }   
        return false;
    }
}
