use Sonata\AdminBundle\Route\RouteCollection;

class ConfigAdmin extends Admin
{

protected function configureFormFields(FormMapper $formMapper)
{   

    $formMapper
        ->with('System Settings')
            ->add('Name','text', array('label' => "Configuration Name"))
            ->add('Language', 'choice', array(
                'label' => 'System Language',
                'choices' => array(0 => 'English', 1 => 'Swedish'),
                'preferred_choices' => array(0),
                ))
            ->add('commonmail','text', array('label' => "Common e-Mail"))

Yes, you can set a flash message in an admin class. First, you can define a custom flash message type for the SonataCoreBundle. For example, if you want a success flash message type, add this in the app/config/config.yml file:

sonata_core:
    flashmessage:
        success:
            types:
                - { type: mytodo_success, domain: MyToDoBundle }

Then, you need to know when to set the message. For example, if you want to set the message after creating a new entity, you can do so overriding the postPersist function in your admin class, and adding the message in the Symfony flash bag:

public function postPersist($object) {
    $this->getRequest()->getSession()->getFlashBag()->add("mytodo_success", "My To-Do custom success message");
}

This way, the message will be displayed whenever you create a new entity at the admin class.

You can also use the default type success:

public function postPersist($object) {
    $this->getRequest()->getSession()->getFlashBag()->add("success", "My To-Do custom success message");
}

"success", "warning" and "error" types seems to be supported in sonata — Nicolas Janel, Jul 27 '15 at 17:47
The problem is that you get at last two messages, the new added one, and the one by default. How to override or remove the default one ? — smarttech, May 14 '19 at 15:23

Because it is an Admin class I get the flashbag over the Session service:

protected function whereever()
{
    $this->getFlashBag()->add(
        'info',
        'Your message'
    );
}
...
protected function getFlashBag()
{
    return $this->getConfigurationPool()->getContainer()->get('session')->getFlashBag();
}

Cheers

You are talking about an admin class, not a controller.

And this is not possible by default. Best way to do this is to write a custom CRUDController (extend from default one) and handle it there.

incorrect answer that shouldn't be the accepted one : as described in other answers, you can inject the session service to use the flashbag in any class where you can inject services, including Sonata admin classes. – Nicolas Janel Jul 27 '15 at 17:44

You need to inject the session service into your admin class.
