how to show specific field of a form for 'create' and 'edit' action - Symfony3

I have a simple FormType attached to an entity called media which I rendered in my view. I have a newAction that lets me create my object, and a editAction that lets me edit it with my same form in my controller. However I don't want some field appears in my edit view` as I already entered them when I created it.

But even though I use form_row to specifically render my form line by line, when I add the form_end at the end, it renders all my fields, even the ones I didn't call.

My FormType

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('name', FileType::class, array(
            'data_class'          => null,
            'label'               => "Add an image"
        ))
        ->add('context', ChoiceType::class, array(
            'label'               => 'image section',
            'choices' => array(
                'header' => 'header',
                'middle' => 'middle',
            )
        ))
        ->add('save', SubmitType::class, array(
            'label'               => "Add"
        ));
}

My view

{{ form_start(editForm) }}
{{ form_row(editForm.name) }}
{{ form_row(editForm.save) }}
{{ form_end(editForm) }}

But even if I use the form rows, it actually shows my context field in the view, which I didn't call. So I tried some hack to get around it.

this one worked but when I click on submit form, it shows me an error that context field cannot be null, so this doesn't do the trick

{% do editForm.context.setRendered %}

And I found a way to do it with jQuery to hide the form like this

<script>
        $(document).ready(function () {
            $("#media_context").parent().hide();
        });
    </script>

the jQuery works and hide my row in my form. But I was wondering if I could do it without using jQuery and be able to render only specific field of my form in my view?

From the symfony docs:

This helper (form_end) also outputs form_rest() unless you set render_rest to false.

form_rest(view, variables)

This renders all fields that have not yet been rendered for the given form.

{# don't render unrendered fields #}
{{ form_end(form, {'render_rest': false}) }}

Try this

{{ form_start(editForm) }}
{{ form_row(editForm.name) }}
{{ form_row(editForm.save) }}
{{ form_end(editForm, {'render_rest': false}) }}

In Symfony 2, you could remove some fields from the builder when editing your entity. Your edit form must extends your create form in Symfony 2.

I think you can do the same in Symfony 3, try something like :

class EditType extends CreateType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        parent::buildForm($builder, $options);

        $builder
            ->remove('context') //remove the fields that no longer needed
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        /...
    }
}

You don't need to change CreateType

class Createtype extends AbstractType
{
  public function buildForm(FormBuilderInterface $builder, array $options)
  {
    $builder
        ->add('name', FileType::class, array(
            'data_class'          => null,
            'label'               => "Add an image"
        ))
        ->add('context', ChoiceType::class, array(
            'label'               => 'image section',
            'choices' => array(
                'header' => 'header',
                'middle' => 'middle',
            )
        ))
        ->add('save', SubmitType::class, array(
            'label'               => "Add"
        ));
  }
}
