Sonata Admin search feature : The Request object has not been set

Question

I want to activate the sonata admin search feature after the migration to of symfony to version 3.4.2. I found a problem in sonata block service:

An exception has been thrown during the rendering of a template ("The Request object has not been set").

this is sonata block configuration :

sonata_block.yml

sonata_block:
    default_contexts: [cms]
    blocks:
        sonata.admin.block.admin_list:
            contexts:   [admin]
        sonata.admin.block.search_result:
            contexts: [admin]
        sonata.block.service.text:
        sonata.block.service.rss:

any solution please ?

Answer 1

The solution is to override the get request function because she throws an exception:

  public function getRequest()
    {
        if (!$this->request) {
            throw new \RuntimeException('The Request object has not been set');
        }

        return $this->request;
    }

so I create a class that extends the abstract admin and make every class in my admin folder extends from it:

class MYAdmin extends AbstractAdmin
{
    /**
     * {@inheritdoc}
     */
    public function getRequest()
    {
        if (!$this->request) {
            return $this->request = $this->getConfigurationPool()->getContainer()->get('request_stack')->getCurrentRequest();
        }
        return $this->request;
    }
}
