将FormType用于Symfony2中的“新”和“编辑”数据

Question

I'm trying to use one form to add and edit data in my "Customer" Entity.

Here is the FormType:

    <?php

namespace Ourentec\CustomersBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class CustomerType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name', 'text', array(
                'label' => 'Nombre *',
                'required' => true,
                'max_length' => 20,
            ))
            ->add('lastname', 'text', array(
                'label' => 'Apellido',
                'required' => false
            ))
            ->add('address', 'textarea', array(
                'label' => 'Dirección',
                'required' => false
            ))
            ->add('phone', 'text', array(
                'label' => 'Teléfono *',
                'required' => true
            ))
            ->add('pass', 'text', array(
                'label' => 'Contraseña *',
                'required' => true
            ))
            ->add('tasks', 'textarea', array(
                'label' => 'Tareas',
                'required' => false
            ))
            ->add('email', 'text', array(
                'label' => 'Email',
                'required' => false
            ))
            ->add('status', 'choice', array(
                'label' => 'Estado',
                'required' => true,
                'choices' => array(
                    '' => 'Selecciona un estado',
                    'Pendiente' => 'Pendiente',
                    'En Curso' => 'En Curso',
                    'Terminado' => 'Terminado'
                )
            ))
            ->add('location', 'choice', array(
                'label' => 'Ubicación',
                'required' => true,
                'choices' => array(
                    '' => 'Selecciona una ubicación',
                    'Taller' => 'Taller',
                    'Tienda' => 'Tienda',
                    'Servicio Técnico Oficial' => 'Servicio Técnico Oficial',
                    'Entregado' => 'Entregado'
                )
            ))
            ->add('save', 'submit', array(
                'label' => 'Añadir'
            ));
    }

    /**
     * @return string
     */
    public function getName()
    {
        return 'ourentec_customersbundle_customer';
    }
}

And here are the controllers for new and edit "customer":

public function newCustomerAction(Request $request)
    {
        $customer = new Customer();

        // invoke form and associate a customer object
        $form = $this->createForm(new CustomerType(), $customer);

        // check if form is submitted
        $form->handleRequest($request);

        if ($form->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $em->persist($customer);
            $em->flush();

            $this->get('session')->getFlashBag()->add(
                'msg',
                'Ficha creada correctamente!'
            );
            return $this->redirect($this->generateUrl('customers_index'));

        }

        return $this->render('CustomersBundle:Customers:new.html.twig', array('form' => $form->createView()));
    }

    public function editCustomerAction(Request $request)
    {
        $customerModel = $this->get('customer_model');
        $historyModel = $this->get('history_model');

        $customer = $customerModel->getCustomerForAdmin($request->get('id'));

        $histories = $historyModel->getHistory($request->get('id'));

        $form = $this->createForm(new CustomerType(), $customer);


        return $this->render('CustomersBundle:Customers:edit.html.twig', array(
            'customer' => $customer,
            'histories' => $histories,
            'form' => $form->createView()));
    }

And to end, the edit view, because the "new" one works perfectly:

{% block content %}
    {% if customer is defined %}
        {% set customer = customer[0] %}
        <h2>Datos de {{ customer.name }}</h2>
        <a href="{{ path('customers_index') }}" class="btn">Volver</a>
        <p></p>

        {{ form_start(form) }}
        <table class="table">
            <tr>
                <td>ID</td>
                <td>{{ customer.id }}</td>
            </tr>

            <tr>
                <td>Fecha de Alta</td>
                <td>{{ customer.date|date("d-m-Y @ H:m:s") }}</td>
            </tr>

            <tr>
                <td>Nombre</td>

            </tr>

            <tr>
                <td>Estado Actual</td>

                <td>Apellido</td>
                <td>{{ form_widget(form.lastname) }}</td>
            </tr>

            <tr>
                <td>Dirección</td>

                <td>

                </td>
            </tr>

            </tr>

            <tr>
                <td>Estado *</td>
                <td>
                    {{ form_widget(form.status) }}

                    {{ form_widget(form.location) }}
                </td>
            </tr>

            <tr>
                <td colspan="2">
                    <input type="submit" class="btn btn-success" name="edit" value="Guardar"/>
                    <a href="{{ path('customers_index') }}" class="btn">Volver</a>
                </td>
            </tr>
        </table>
        {{ form_end(form) }}

        {% if histories is defined %}
            {% set histories = histories[0] %}

Well, my problem is that I can't pre-fill the Entity data into text fields. As you can see, in my controller (editCustomerAction) I'm getting the customer info from my database (I checked it in my error_log and in the Symfony2 toolbar), and I pass that info to the view. But I don't know why it doesn't work. I read de official docs but there are no examples to pre-fill data...

Thanks in advance!

EDITED: Here is the model. I do a "getArrayResult()" in the DQL because if a do a

$customer = $this->getDoctrine()->getRepository('CustomersBundle:Customer')->find($request->get('id'));

I get a "PHP Fatal error: Allowed memory size..." error..

Model functions:

class CustomerModel
{
    protected $em;

    public function __construct(\Doctrine\ORM\EntityManager $em)
    {
        $this->em = $em;
    }


    public function getAllCustomersForAdmin($userId)
    {
        $customers = $this->em->createQuery(
            'select c, ctrl.seen, ctrl.date as edited from CustomersBundle:Customer c
            join CustomersBundle:Control ctrl
            where c.id = ctrl.customer and ctrl.user = :id order by ctrl.date desc, c.date desc')
            ->setParameter('id', $userId)
            ->getArrayResult();

        return $customers;
    }

    public function getCustomerForAdmin($customerId)
    {
        $customer = $this->em->createQuery(
            'select c from CustomersBundle:Customer c where c.id = :id')->setParameter('id', $customerId)
            ->getArrayResult();

        return $customer;
    }
} 

Answer 1

You're are giving an array to your form. That's why that didn't work.

In your model, you've to return a single result :

public function getCustomerForAdmin($customerId)
{
    $customer = $this->em->createQuery(
        'select c from CustomersBundle:Customer c where c.id = :id')->setParameter('id', $customerId)
        ->getSingleResult();

    return $customer;
}

You can use the function : getOneOrNullResult() to return a null if the customer doesn't exist. In this case, the getSingleResult() will throw an error.
