此包为使用 Tetranz Select2EntityBundle 提供辅助功能。

Searcher 类定义了在 Select2 字段中使用的实体配置。

配置

向默认控制器添加路由

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

在 config.yml 中添加您的 Searcher 类命名空间。默认为 App\Util

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

创建 Select2 字段

首先，为您的字段中要使用的实体创建一个 Searcher 类。

<?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'];
}

然后，在您的表单中添加一个 Select2 字段

<?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',
        ]);
    }
}

保护默认控制器访问

您可以创建一个 Voter 来控制对不同实体的访问。

<?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;
    }
}
