21. Batch actions

Batch actions are actions triggered on a set of selected objects. By default, Admins have a delete action which allows you to remove several entries at once.

21.1. Defining new actions

To create a new custom batch action which appears in the list view follow these steps:

Override getBatchActions() in your Admin class to define the new batch actions by adding them to the $actions array. Each entry has two settings:

  • label: The name to use when offering this option to users, should be passed through the translator
  • ask_confirmation: defaults to true and means that the user will be asked for confirmation before the batch action is processed

For example, lets define a new merge action which takes a number of source items and merges them onto a single target item. It should only be available when two conditions are met:

  • the EDIT and DELETE routes exist for this Admin (have not been disabled)
  • the logged in administrator has EDIT and DELETE permissions

// In your Admin class

public function getBatchActions()
    // retrieve the default batch actions (currently only delete)
    $actions = parent::getBatchActions();

    if (
      $this->hasRoute('edit') && $this->isGranted('EDIT') &&
      $this->hasRoute('delete') && $this->isGranted('DELETE')
    ) {
        $actions['merge'] = array(
            'label' => $this->trans('action_merge', array(), 'SonataAdminBundle'),
            'ask_confirmation' => true


    return $actions;

21.2. (Optional) Overriding the batch selection template

A merge action requires two kinds of selection: a set of source objects to merge from and a target object to merge into. By default, batch_actions only let you select one set of objects to manipulate. We can override this behavior by changing our list template (list__batch.html.twig) and adding a radio button to choose the target object.

{# in Acme/ProjectBundle/Resources/views/CRUD/list__batch.html.twig #}
{# See SonataAdminBundle:CRUD:list__batch.html.twig for the current default template #}

{% extends admin.getTemplate('base_list_field') %}

{% block field %}
    <input type="checkbox" name="idx[]" value="{{ }}" />

    {# the new radio #}
    <input type="radio" name="targetId" value="{{ }}" />
{% endblock %}

And add this:

// Acme/ProjectBundle/AcmeProjectBundle.php

public function getParent()
    return 'SonataAdminBundle';

See the Symfony bundle overriding mechanism for further explanation of overriding bundle templates.

21.3. (Optional) Overriding the default relevancy check function

By default, batch actions are not executed if no object was selected, and the user is notified of this lack of selection. If your custom batch action needs more complex logic to determine if an action can be performed or not, just define a batchAction<MyAction>IsRelevant method (e.g. batchActionMergeIsRelevant) in your CRUDController class. This check is performed before the user is asked for confirmation, to make sure there is actually something to confirm.

This method may return three different values:

  • true: The batch action is relevant and can be applied.
  • false: Same as above, with the default “action aborted, no model selected” notification message.
  • a string: The batch action is not relevant given the current request parameters (for example the target is missing for a merge action). The returned string is a message displayed to the user.

// In Acme/ProjectBundle/Controller/CRUDController.php

public function batchActionMergeIsRelevant(array $selectedIds, $allEntitiesSelected)
    // here you have access to all POST parameters, if you use some custom ones
    // POST parameters are kept even after the confirmation page.
    $parameterBag = $this->get('request')->request;

    // check that a target has been chosen
    if (!$parameterBag->has('targetId')) {
        return 'flash_batch_merge_no_target';

    $targetId = $parameterBag->get('targetId');

    // if all entities are selected, a merge can be done
    if ($allEntitiesSelected) {
        return true;

    // filter out the target from the selected models
    $selectedIds = array_filter($selectedIds,
        function($selectedId) use($targetId){
            return $selectedId !== $targetId;

    // if at least one but not the target model is selected, a merge can be done.
    return count($selectedIds) > 0;

21.4. (Optional) Executing a pre batch hook

In your admin class you can create a preBatchAction method to execute something before doing the batch action. The main purpose of this method is to alter the query or the list of selected ids.


// In your Admin class

public function preBatchAction($actionName, ProxyQueryInterface $query, array & $idx, $allElements)
    // altering the query or the idx array
    $foo = $query->getParameter('foo')->getValue();

    // Doing something with the foo object
    // ...

    $query->setParameter('foo', $bar);

21.5. Define the core action logic

The method batchAction<MyAction> will be executed to process your batch in your CRUDController class. The selected objects are passed to this method through a query argument which can be used to retrieve them. If for some reason it makes sense to perform your batch action without the default selection method (for example you defined another way, at template level, to select model at a lower granularity), the passed query is null.


You can check how to declare your own CRUDController class in the Architecture section.


// In Acme/ProjectBundle/Controller/CRUDController.php

public function batchActionMerge(ProxyQueryInterface $selectedModelQuery)
    if (!$this->admin->isGranted('EDIT') || !$this->admin->isGranted('DELETE'))
        throw new AccessDeniedException();

    $request = $this->get('request');
    $modelManager = $this->admin->getModelManager();

    $target = $modelManager->find($this->admin->getClass(), $request->get('targetId'));

    if( $target === null){
        $this->addFlash('sonata_flash_info', 'flash_batch_merge_no_target');

        return new RedirectResponse(

    $selectedModels = $selectedModelQuery->execute();

    // do the merge work here

    try {
        foreach ($selectedModels as $selectedModel) {

    } catch (\Exception $e) {
        $this->addFlash('sonata_flash_error', 'flash_batch_merge_error');

        return new RedirectResponse(

    $this->addFlash('sonata_flash_success', 'flash_batch_merge_success');

    return new RedirectResponse(
