Answer 1

您的实体类Groupe不正确。

它不会扩展Sonata管理类。
方法configureListFields，configureFormFields，configureDatagridFilters不应该在这里。它们必须位于单独的管理类（模拟symfony控制器类）

示例：

<?php

namespace Tic\ClasseBundle\Controller\Admin;

use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Form\FormMapper;

class GroupeAdmin extends Admin
{
    protected function configureListFields(ListMapper $listMapper)
    {
        $listMapper
            ->addIdentifier('id')
            ->addIdentifier('name')
            ->add('country');
    }

    protected function configureFormFields(FormMapper $form)
    {
        $form
            ->add('id', null, [
                'attr' => [
                    'readonly' => true,
                ],
            ])
            ->add('name')
            ->add('country');
    }

    protected function configureDatagridFilters(DatagridMapper $filter)
    {
        $filter
            ->add('id')
            ->add('name')
            ->add('country');
    }
}
