How can I change symfony2 form fields default options globally? - symfony

Question

Is there a way to change default options for form fields globally in symfony2?
More specifically, I want to change the render of ALL datetime fields to use single_text instead of the default choice widget.
Can it be done? Or do I need to implement a custom type and set the default in there, like for example the birthdate type?
I prefer an option that leads to minimal changes in the codebase.

The post is old, but you can use an alternative method, overriding the DateType symfony class ...
service.yml
services:
form.type.date:
class: "YourApp\YourBundle\Form\DateType"
tags:
- { name: "form.type", alias: "date" }
DateType.php
<?php
namespace YourApp\YourBundle\Form;
use Symfony\Component\Form\Extension\Core\Type\DateType as SymfonyDateType;
use Symfony\Component\OptionsResolver\OptionsResolver;
class DateType extends SymfonyDateType
{
/**
* {#inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
parent::configureOptions( $resolver );
$resolver->setDefault( 'widget', 'single_text' );
}
}
You can check if the service is taken by container
$ ./app/console debug:container | grep form.type.date
form.type.date YourApp\YourBundle\Form\DateType
form.type.datetime Symfony\Component\Form\Extension\Core\Type\DateTimeType

You have to define a form theme.
It's very easy and requires only a little bit coding time. First of all, you have to know which block to customize; in that case, you can do something like
{% block my_data_widget %}
{% spaceless %}
{% if type is defined and type == 'date' %}
// do all your customization
{% else %}
// don't know ...
{% endif %}
{% endspaceless %}
{% endblock form_widget_simple %}
Now that you have defined this snippet of code, you can use it into your main template (or whatever you use into your form views) in that way
{% form_theme form 'YourBundle:Form:myDataWidget' %}
Last but not least important, you have to place your form theme into Resources/views folder. In my example, your path will be Resources/views/Form/myDataWidget
Update
Did you tried with
{% set type = type|default('single_text') %}
or something like that?
