Formulir Symfony dengan Doctrine Class Table Inheritance (CTI)

Dalam pertanyaan sebelumnya saya bertanya bagaimana menangani formulir besar, hasilnya adalah Single Table Inheritance (STI) atau CTI, Pemetaan Warisan . Saya telah memilih untuk CTI.

Sekarang saya sedang membahas cara membuat formulir dengan CTI. Gambaran singkat tentang jenis atau hubungan yang ada.

Masing inspection- masing bisa memiliki satu atau lebih surfaces. Setiap permukaan terdiri dari banyak sub entitas, seperti: surface_leakage, surface_tensionatau surface_slope. Seperti yang Anda lihat surfacememiliki CTI dengan sub entitas. Beberapa bidang tumpang tindih (taruh di induk), beberapa tidak (taruh di anak). Tetapi pada akhirnya saya membutuhkan satu formulir dengan semua bidang dikelompokkan berdasarkan permukaan kemudian oleh anak (mungkin Bootrap runtuh).

Menyiapkan relasinya tidak terlalu sulit, tetapi menggunakannya ke dalam bentuk itu sulit dan saya tidak yakin bagaimana saya bisa menangani ini. Lihat kode di bawah ini dengan kode dua persetujuan

<?php
class Inspection
{
    /**
     * @OneToMany(targetEntity="App\Entity\Surface", mappedBy="inspection")
     */
    protected $surfaces; } /** * @Entity * @InheritanceType("JOINED") * @DiscriminatorColumn(name="discr", type="string") * @DiscriminatorMap({"surface" = "Surface", "surface_leagage" = "SurfaceLeakage", ...}) */ class Surface { protected $inpection;
    protected $description; } class SurfaceLeakage extends Surface { protected $leakageLevel;
}

// .. other child classes (SurfaceTension, SurfaceSlope, ...)

class InspectionType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        // ...

        $builder->add('surfaces', CollectionType::class, [ 'entry_type' => SurfaceType::class, ]); } } // Approach 1, where each child is added to the SurfaceType // with this approach data should be mapped false // This approach ensures that I only have to call SurfaceType once and all fields are loaded, but // could not make this work with data from DB through CIT. // Also this method does not allow me to add field description (from parent) to all childTypes class SurfaceType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('leakage', SurfaceLeakageType::class, array('mapped' => false));
        $builder->add('tension', SurfaceTensionType::class, array('mapped' => false)); // ... } public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([ 'data_class' => Surface::class, ]); } } class SurfaceLeakageType extends AbstractType { } // Approach 2, where each childFormType could extend SurfaceType, like below but how to call/create the // form and handling the data. // With this approuch i could parent fields to the child class SurfaceLeakageType extends SurfaceType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('description', TextareaType::class); // field from parent or ...
        parent::buildForm($builder, $options);


        $builder->add('leakageLevel', IntegerType::class); // own field
        //  ...
    }
}

Lalu ada form inherit_data

// Approach 3, inherit data, now each child should add this as a field like below,
// but how the only thing I'm doing on InspectionType build Surfaces as collection so
// i think inherit data also doesn't work
class SurfaceType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void { $builder->add('description', TextareaType::class);
    }

    public function configureOptions(OptionsResolver $resolver): void { $resolver->setDefaults([
            'inherit_data' => true,
        ]);
    }
}

class SurfaceLeakageType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        // inherit fields
        $builder->add('leakage', SurfaceType::class, [ 'data_class' => SurfaceLeakage::class, ]); $builder->add('leakageLevel', IntegerType::class); // own field
    }
}

Semoga seseorang bisa membantu saya
