Sonata admin bundle, manipulate objects

Question

I have 2 entities with one to many relationship project and prototype And I\'ve been looking for a way to list the prototypes that belong to a project in the show action . here

Answer 1

One way is to define the template for your prototypes field in showMapper

protected function configureShowFields(ShowMapper $showMapper)
{
    $showMapper ->add('prototypes',null, array('template' => 'NamespaceYourBundle::Admin/prototypes.html.twig'));

}

Create Admin folder in your bundle's resources folder and create prototypes.html.twig file ,extend your twig template with sonata's base_show_field.html.twig template and in {% block field %} define your own markup looping through all related prototypes

{% extends 'SonataAdminBundle:CRUD:base_show_field.html.twig' %}
{% block field %}
    {% spaceless %}
        {% if object.getPrototypes() is not empty %}
            
                ...
                ...
                ...
            
            {% for prototype in object.getPrototypes() %}
            
                ...
                ...
                ...
            
            {% endfor %}
            

            

            

            
Nom
            
Description
            
            

                
{{ prototype.getNom() }}
                
{{ prototype.getDescription() }}
            
        {% endif %}
    {% endspaceless %}
{% endblock %}
