Protect Entities Using ACLs
Using ACLs you can granularly grant access to your entities. Doing so requires three steps:
Add access checks to where your entities are displayed or manipulated.
Activating ACL Checks on your Entities
To have your entity available in the admin UI to be able to assign permissions to your users, you have to enable ACLs for these entities using the @Config
annotation:
namespace Acme\Bundle\DemoBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Oro\Bundle\EntityConfigBundle\Metadata\Annotation\Config;
/**
* ORM Entity Favorite.
*
* @ORM\Table(
* name="acme_demo_favorite"
* )
* @Config(
* defaultValues={
* "security"={
* "type"="ACL",
* "permissions"="All",
* "group_name"="",
* "category"="",
* },
* }
* )
*/
After you have done this and have cleared the cache, you can toggle all kinds of permission checks (CREATE
, EDIT
, DELETE
, VIEW
, and ASSIGN
) in the user role management interface.
Tip
You can use the optional group_name
attribute to group entities by application. The value of this attribute is used to split the configured access control list into application scopes.
Creating Access Control Lists
You have two options to define your custom access control lists:
In your controller class, you can use the
@Acl
annotation:
namespace Acme\Bundle\DemoBundle\Controller;
use Acme\Bundle\DemoBundle\Entity\Favorite;
use Oro\Bundle\SecurityBundle\Annotation\Acl;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
/**
* Contains CRUD actions for Favorite
*
* @Route("/favorite", name="acme_demo_favorite_")
*/
class FavoriteController extends AbstractController
{
/**
* @Route("/custom", name="custom")
* @Template("@AcmeDemo/Favorite/index.html.twig")
* @Acl(
* id="acme_demo_favorite_custom",
* type="entity",
* class="AcmeDemoBundle:Favorite",
* permission="VIEW"
* )
* @CsrfProtection()
*/
public function customAction(): array
{
return ['entity_class' => Favorite::class];
}
}
Using the @Acl
annotation does not only create new access control lists to which you can refer in other parts of your code, it also triggers the access decision manager when your actions are accessed by users and thus protect them from being accessed without the needed permissions.
If you do not want to protect any controller methods or if you prefer to keep the definition of your ACLs separated from the application code, you can define them using some YAML config in a file named
acls.yml
:
acls:
favorites_edit:
type: entity
class: AcmeDemoBundle:Favorite
permission: EDIT
Performing Access Checks
Once you have configured the ACLs, you can protect all application parts. You can use the isGranted()
method of the security.authorization_checker
service (which is an instance of the Symfony\Component\Security\Core\Authorization\AuthorizationCheckerInterface) anywhere in your PHP code:
$authorizationChecker = $this->get('security.authorization_checker');
if ($authorizationChecker->isGranted('acme_static_pages')) {
// do something when the user is granted permissions for the acme_static_pages ACL
}
You can set the second parameter to check access on Object level (with Access Level check):
$taskEntity = $this->getTask();
$authorizationChecker = $this->get('security.authorization_checker');
if ($authorizationChecker->isGranted('acme_task_edit', $taskEntity)) {
// do something when the user is granted permissions for the acme_task_edit ACL of the entity in $taskEntity
}
When you do not have proper ACL annotation, you can set the first parameter as the permission name you want to check:
$taskEntity = $this->getTask();
$authorizationChecker = $this->get('security.authorization_checker');
if ($authorizationChecker->isGranted('EDIT', $taskEntity)) {
// do something when the user is granted EDIT permission for the $taskEntity
}
This example will work the same as before. It will check EDIT permission for the Task instance object.
However, there are ways to perform these checks in different parts of your application:
Protecting Controllers Referring to Existing ACLs
You can define new ACLs as shown above and protect your controllers with them in a single step using the @Acl
annotation. However, you can also refer to an existing access control list using the @AclAncestor
annotation:
namespace Acme\Bundle\DemoBundle\Controller;
use Acme\Bundle\DemoBundle\Entity\Task;
use Oro\Bundle\SecurityBundle\Annotation\AclAncestor;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
class TaskController extends AbstractController
{
/**
* @AclAncestor("acme_task_view")
*/
public function viewAction(Task $task)
{
// ...
}
}
Show Parts of Templates Based on Permissions
Inside your templates, you can use the is_granted()
Twig function to check for certain permissions to hide parts of your views for users who do not have the required permissions:
{% block someBlock %}
{% if is_granted('acme_task_edit') %}
Some info if access is granted
{% endif %}
{% endblock %}
In this example, we check access by ACL annotation info without an Object to test. So, is_granted
will return true if the user has any access level to EDIT permission to the Task entity.
If you want to perform a deeper access check, you can set the entity instance as the second parameter of the is_granted()
function:
{% block someBlock %}
{# an `entity` variable contains a Test entity instance #}
{% if is_granted('acme_task_edit', entity) %}
Some info if access is granted
{% endif %}
{% endblock %}
This example illustrates the check of the access level for the given object instance.
If you have no ACL annotation, you can set the permission name directly as the first parameter:
{% block someBlock %}
{# an `entity` variable contains a Test entity instance #}
{% if is_granted('EDIT', entity) %}
Some info if access is granted
{% endif %}
{% endblock %}
Restrict Access to Data Grid Results
In a data grid, you can protect the entire result set (not to show results if the user is not granted access and the action embedding the grid was not protected by accident):
datagrids:
acme-tasks-grid:
source:
acl_resource: acme_task_view
# ...
Hide Unaccessible Grid Actions
You can also use the acl_resource
option to hide actions in a data grid the user does not have access to:
datagrids:
acme-tasks-grid:
# ...
actions:
# ...
edit:
type: navigate
label: Edit
link: update_link
icon: edit
acl_resource: acme_task_edit
delete:
type: delete
label: Delete
link: delete_link
icon: trash
acl_resource: acme_task_delete
Check Access on ORM Queries
You can protect your Doctrine ORM query with the apply
method of the oro_security.acl_helper
service.
namespace Acme\Bundle\DemoBundle\Controller;
use Acme\Bundle\DemoBundle\Entity\Task;
use Doctrine\ORM\Query;
use Doctrine\ORM\QueryBuilder;
use Oro\Bundle\SecurityBundle\ORM\Walker\AclHelper;
class TaskController extends Controller
{
/**
* @param Task $task
* @return array
*/
public function viewAction(Task $task)
{
/** @var QueryBuilder $qb */
$qb = $this->getSomeQuery();
/** @var Query $query */
$query = $this->getContainer()->get('oro_security.acl_helper')->apply($qb);
$result = $query->getResult();
// ...
}
}
As a result, the query will be modified, and the result data set will contain only the records the user can see.
By default, VIEW permission is used as the second parameter. If you want to check another permission, you can set it as the second parameter of the apply
method.
