Question

我有以下关系：

[实体] SesiuneUtilitati- | one_to_one | - ＆GT; [实体] UtilitatiElectricitateCoeficient- | one_to_many | - ＆GT; [实体] UtilitatiElectricitate

我想创建一个包含所有3个实体的表单

         $clienti = $this->getClienti($idSocietate);
         $sesiuneUtilitati = new SesiuneUtilitati();

                $usr = $this->get('security.context')->getToken()->getUser();
                $now = new \DateTime();

        }

             'form' => $form->createView(),
             'clienti' => $clienti,
         ));
     }

我在这里做错了什么？字段utilitatiElectricitate的字段在树枝中不可用。例如，如果我尝试form.utilitatiElectricitateCoeficient.utilitatiElectricitate [0] .kwh我得到一个错误，键0不存在。

创建SesiuneUtilitatiType以包含所有其他形式：

<?php


namespace Mnv\CoreBundle\Form;

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


class SesiuneUtilitatiType extends AbstractType
{


    public function buildForm(FormBuilderInterface $builder, array $options)
    {

        $builder->add('utilitatiTotal', new UtilitatiTotalType());

        $builder->add('utilitatiElectricitateCoeficient', new UtilitatiElectricitateCoeficientType());

           .
           .
           .

       $builder->add('Salveaza datele si genereaza facturi', 'submit');

    }



    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Mnv\CoreBundle\Entity\SesiuneUtilitati',
            'cascade_validation' => true,
        ));
    }

    public function getName()
    {
        return 'sesiune_utilitati';
    }
}

和UtilitatiElectricitateCoeficientType：

<?php

namespace Mnv\CoreBundle\Form;

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

class UtilitatiElectricitateCoeficientType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('lei','text', array('required' => false));
        $builder->add('coeficient','text', array('required' => false));
        $builder->add('kwh','text', array('required' => false));
        $builder->add('leikw','text', array('required' => false));  

        $builder->add('utilitatiElectricitate', 'collection', array(
                                                                    'type' => new UtilitatiElectricitateType(), 
                                                                    'allow_add' => true, 
                                                                    'prototype' => true, 
                                                                    'by_reference' => false
                                                                    ));
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Mnv\CoreBundle\Entity\UtilitatiElectricitateCoeficient',
            'cascade_validation' => true,
        ));
    }

    public function getName()
    {
        return 'utilitati_electricitate_coeficient';
    }
}

和UtilitatiElectricitateType：

<?php

namespace Mnv\CoreBundle\Form;

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

class UtilitatiElectricitateType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {

        $builder->add('kwh','text', array('required' => false));
        $builder->add('pret','text', array('required' => false));
        $builder->add('total','text', array('required' => false));

    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Mnv\CoreBundle\Entity\UtilitatiElectricitate',
            'cascade_validation' => true,
        ));
    }

    public function getName()
    {
        return 'utilitati_electricitate';
    }
}

Answer 1

您必须创建一个SesiuneUtilitatiType，您将其嵌入UtilitatiElectricitateCoeficientType，现在最后一个将嵌入UtilitatiElectricitateType。您应该阅读embedded forms的文档，以清楚地了解要遵循的规则
