如何覆盖奏鸣曲管理员中的显示字段

I want show the list of multiple attributes Name => value in a table overriding single field of only for PortsAdmin in ShowMapper

Ports Entity mapped with PortsAttributes Entity.

Relation of entity is OneToMany Ports with multiple attributes.

Admin View (Edit Action)

Show Action

I want change attribute view same as edit Action.

You can create a custom template for the PostAttributes:

Example:

/* ShowMapper in admin */
$showMapper->add('attributes', null, array(
    'template' => 'YOUR_TEMPLATE.html.twig' // <-- This is the trick
));

In your template, you can extend the base show field (SonataAdminBundle:CRUD:base_show_field.html.twig), and override the field block. The variable named value stores the data in twig.

Example:

YOUR_TEMPLATE.html.twig

{% extends 'SonataAdminBundle:CRUD:base_show_field.html.twig' %}

{% block field %}
    {% for val in value %}
        {{ val.name }} - {{ val.value }} {# I'm just guessing the object properties #}
        <br/>
    {% endfor %}
{% endblock %}
