Symfony表单（作为独立组件与Doctrine）EntityType不工作 [英] Symfony forms (as standalone component with Doctrine) EntityType not working

问题描述

我使用Symfony表单（v3.0），而没有其余的Symfony框架。使用Doctrine v2.5。

I'm using Symfony forms (v3.0) without the rest of the Symfony framework. Using Doctrine v2.5.

我创建了一个表单，这里是表单类型类：

I've created a form, here's the form type class:

class CreateMyEntityForm extends BaseFormType {

    public function buildForm(FormBuilderInterface $builder, array $options){
        $builder->add('myEntity', EntityType::class);
    }
}

加载页面时，我收到以下错误。

When loading the page, I get the following error.

参数1传递给
Symfony\Bridge\Doctrine\Form\Type\DoctrineType :: __ construct（ ）必须是
一个Doctrine\Common\Persistence\ManagerRegistry的实例，none
给定，在$ b $中的/var/www/dev3/Vendor/symfony/form/FormRegistry.php中调用b line 85

Argument 1 passed to Symfony\Bridge\Doctrine\Form\Type\DoctrineType::__construct() must be an instance of Doctrine\Common\Persistence\ManagerRegistry, none given, called in /var/www/dev3/Vendor/symfony/form/FormRegistry.php on line 85

我相信有一些配置需要放在这里，但我不知道如何创建一个类实现ManagerRegistryInterface - 如果这是正确的事情。

I believe there's some configuration that needs putting in place here, but I don't know how to create a class that implements ManagerRegistryInterface - if that is the right thing to do.

任何指针？

编辑 - 这里是我的设置Doctrine的代码

Edit - here is my code for setting up Doctrine

use Doctrine\ORM\EntityManager;
use Doctrine\ORM\Tools\Setup;

class Bootstrap {

    //...some other methods, including getCredentials() which returns DB credentials for Doctrine

    public function getEntityManager($env){

        $isDevMode = $env == 'dev';

        $paths = [ROOT_DIR . '/src'];

        $config = Setup::createAnnotationMetadataConfiguration($paths, $isDevMode, null, null, false);

        $dbParams = $this->getCredentials($env);

        $em = EntityManager::create($dbParams, $config);

        return $em;
    }
}

推荐答案

相信我，你要麻烦了！

Believe me, you're asking for trouble!

EntityType :: class 在与Symfony框架紧密结合时起作用（引擎盖下有魔术 - 通过DoctrineBundle）。否则，您需要编写大量代码才能正常工作。

不值得努力！

EntityType::class works when it is seamsly integrated to "Symfony" framework (there's magic under the hoods - via DoctrineBundle). Otherwise, you need to write a lot of code for it to work properly.
Not worth the effort!

如果您创建一个实体存储库并将其注入到表单构造函数中，然后在 ChoiceType :: class 字段中使用，这将会更容易。像这样的事情：

It's a lot easier if you to create an entity repository and inject it in form constructor, then use in a ChoiceType::class field. Somethink like this:

<?php
# you form class
namespace Application\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class InvoiceItemtType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('product', ChoiceType::class, [
            'choices' => $this->loadProducts($options['products'])
        ]);
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(['products' => [],]); # custom form option
    }

    private function loadProducts($productsCollection)
    {
        # custom logic here (if any)
    }
}

应用程序中的某个位置：

And somewhere in application:

$repo = $entityManager->getRepository(Product::class);
$formOptions = ['products' => $repo->findAll()];
$formFactory = Forms::createFormFactory();
$formFactory->create(InvoiceItemtType::class, new InvoiceItem, $formOptions);

这是要点！
