Raw filter on Sonata Admin Bundle configureShowFields

问题

I'm doing a project with Symfony2 and Sonata Admin Bundle. How I can apply the filter raw of twig (to display formated text) in action configureShowFields?

I would not override Sonata templates...

The code of my configureShowFields:

protected function configureShowFields(ShowMapper $showMapper)
    {
        $showMapper
            ->add('active')
            ->add('title')
            ->add('subtitle') // I need this field with twig RAW filter
            ->add('description') //I need this field with twig RAW filter
            ->add('url')
            ->add('date')
            ->add('tags')
            ->add('file');
    }

回答1:

You can use the "safe" sonata field option as follow:

protected function configureShowFields(ShowMapper $showMapper)
{
    $showMapper
        ->add('subtitle', null, array('safe' => true))
    ;
}

It will add the "raw" twig filter to your entity field.

From the base_show_field.html.twig:

{% block field %}
    {% if field_description.options.safe %}
       {{ value|raw }}
    {% else %}
       {{ value|nl2br }}
    {% endif %}
{% endblock %}

回答2:

You need to make a custom template.

Under:

sonata_doctrine_orm_admin:
  templates:
    types:
      list:
        array:      SonataAdminBundle:CRUD:list_array.html.twig
        *** other existing declarations ***
        raw:        MyBundle:CRUD:raw.html.twig

Then make the template that the declaration maps to, and give 'raw' as the second argument to add field. It'll then call your new template to render that field.
