Symfony2 - 錯誤phonnumberbundle：無法轉換屬性路徑「phone_number」的值：預期\ libphonenumber \ PhoneNumber

Question

以下是我的實體，表單和DBAL配置爲misd-phonenumberbundle與Symfony2.8集成。但是我仍然得到下面的錯誤，有人可以讓我知道如何解決這個問題嗎？我寫了幾行代碼將字符串轉換爲PhoneNumber obj，然後表單加載正常，但我的問題是我們需要顯式地將其轉換嗎？這是不是自動處理？

實體條目：

/** 
* @ORM\Column(type="phone_number", nullable=true) 
* @AssertPhoneNumber(defaultRegion="US", message="Please specify a valid phone number") 
*/ 
private $phoneNumber; 

DBAL映射：

doctrine: 
dbal: 
types: 
phone_number: Misd\PhoneNumberBundle\Doctrine\DBAL\Types\PhoneNumberType 

表：

->add('phoneNumber', PhoneNumberType::class, array('default_region' => 'US', 'format' => PhoneNumberFormat::NATIONAL, 'required' => false)) 

自定義代碼來處理錯誤：

if($user->getphoneNumber()!="") 
{ 
    $util = $this->container->get('libphonenumber.phone_number_util'); 
    $phoneNUmber = $util->parse($user->getphoneNumber(), "US"); 
    $user->setphoneNumber($phoneNUmber); 
} 
else 
{ 
    $phoneNUmber = new \libphonenumber\PhoneNumber; 
    $user->setphoneNumber($phoneNUmber); 
} 

Error:  

Uncaught PHP Exception Symfony\Component\Form\Exception\TransformationFailedException: Unable to transform value for property path "phone_number": Expected a \libphonenumber\PhoneNumber at webapp/vendor/symfony/symfony/src/Symfony/Component/Form/Form.php line 1149

下面是我的解決辦法。我沒有做過任何一種學說映射在app/config.yml

此解決方案假定MisdPhonenumber束在AppKernel.php

1. 創建數據變壓器註冊：SRC /例/包/表/DataTransformer.php

Data Transformer Class

<?php 

namespace Example\Bundle\Form\DataTransformer; 

use libphonenumber\PhoneNumber; 
use libphonenumber\PhoneNumberFormat; 
use Symfony\Component\Form\DataTransformerInterface; 

class StringToPhoneNumberTransformer implements DataTransformerInterface 
{ 

    // The 'libphonenumber.phone_number_util' service 
    private $phoneNumberUtil; public function __construct($util) 
    { 
     $this->phoneNumberUtil = $util; 
    } 

    /** 
    * Transforms a string (number) to an object (PhoneNumber) 
    * 
    * @param string $phoneNumberString 
    * @return PhoneNumber 
    */ 
    public function transform($phoneNumberString) 
    { 
     if ($phoneNumberString != "") 
     { 
      return $this->phoneNumberUtil->parse($phoneNumberString, "US"); 
     } 
     return new PhoneNumber; 
    } 

    /** 
    * Transforms a string (number) to an object (issue). 
    * 
    * @param PhoneNumber $phoneNumberObject 
    * @return string 
    */ 
    public function reverseTransform($phoneNumberObject) 
    { 
     if ($phoneNumberObject != null) 
     { 
      return $this->phoneNumberUtil->format($phoneNumberObject, PhoneNumberFormat::NATIONAL); 
     } 
     return ''; 
    } 
} 

表格使用數據變壓器

Data Transformer in Form

<?php 

namespace Example\Bundle\Form\Type\User; 

use Example\Bundle\Entity\User; 
use Example\Bundle\Form\DataTransformer\StringToPhoneNumberTransformer; 
use Example\Bundle\Services\States; 
use libphonenumber\PhoneNumberFormat; 
use Misd\PhoneNumberBundle\Form\Type\PhoneNumberType; 
use Symfony\Component\Form\AbstractType; 
use Symfony\Component\Form\Extension\Core\Type\ChoiceType; 
use Symfony\Component\Form\Extension\Core\Type\EmailType; 
use Symfony\Component\Form\Extension\Core\Type\SubmitType; 
use Symfony\Component\Form\Extension\Core\Type\TextType; 
use Symfony\Component\Form\FormBuilderInterface; 
use Symfony\Component\OptionsResolver\OptionsResolver; 

class ContactInfoType extends AbstractType 
{ 
    // The 'libphonenumber.phone_number_util' service private $phoneNumberUtil; 
    public function __construct($util) 
    { 
     $this->phoneNumberUtil = $util; 
    } 

    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
     $builder->add('salutation', TextType::class, array('max_length' => 10, 'required' => false)) 
      ->add('firstName', TextType::class, array('max_length' => 30)) 
      ->add('lastName', TextType::class, array('max_length' => 30)) 
      ->add('email', EmailType::class, array('max_length' => 150)) 
      ->add('phone', PhoneNumberType::class, 
       array('default_region' => 'US', 'format' => PhoneNumberFormat::NATIONAL, 'required' => false)) 
      ->add('stAddress1', TextType::class, 
       array('label' => 'Address Line 1', 'max_length' => 60, 'required' => false)) 
      ->add('stAddress2', TextType::class, 
       array('label' => 'Address Line 2', 'max_length' => 60, 'required' => false)) 
      ->add('city', TextType::class, array('max_length' => 30, 'required' => false)) 
      ->add('state', ChoiceType::class, 
       array('choices' => States::getStates(), 'required' => false, 'choices_as_values' => true)) 
      ->add('zip', TextType::class, array('max_length' => 5, 'required' => false)) 
      ->add('submit', SubmitType::class); 

     $builder->get('phone')->addModelTransformer(new StringToPhoneNumberTransformer($this->phoneNumberUtil)); 
    } 

    public function getBlockPrefix() 
    { 
     return 'ContactInfo'; 
    } 

    public function configureOptions(OptionsResolver $resolver){ 
     // Explicitly bind data class of form. 
     $resolver->setDefaults([ 
      'data_class' => User::class 
     ]); 
    } 
} 

定義形式類型作爲服務配置文件：

Form type as a service

# src/Example/Bundle/Resources/config/services.yml 

services: 
    example.form.contactinfo: 
     class: Example\Bundle\Form\Type\User\ContactInfoType 
    arguments: ["@libphonenumber.phone_number_util"] 
    tags: 
     - { name: form.type }
