Is there a way to specify Doctrine2 Entitymanager implementation class in Symfony2?
(4 answers)
Closed 9 years ago.
I've created some additional methods to help with managing entities in a Symfony2 project. I would like these method to be available on Doctrine's EntityManager which is obtained from the container with the "doctrine.orm.entity_manager" key.
I found this post, and tried implementing it, but it is not working. I get an error that says The attribute "name" must be set for path "doctrine.orm.entity_managers".
This is an older post, so it may be some kind of "trick" that has been deprecated since then; I'm using the latest stable versions of Symfony2 and Doctrine.
Is there a way to override the class that Doctrine uses to create it's default EntityManager, or am I going to have to just create like another service and use that instead?
Way remains the same.
Override parameter doctrine.orm.entity_manager.class from orm.xml in your services.yml with your custom EntityManager class that extends Doctrine\ORM\EntityManager.
Override create method(it changed a little bit)
public static function create($conn, Configuration $config, EventManager $eventManager = null)
{
if ( ! $config->getMetadataDriverImpl()) {
throw ORMException::missingMappingDriverImpl();
}
switch (true) {
case (is_array($conn)):
$conn = \Doctrine\DBAL\DriverManager::getConnection(
$conn, $config, ($eventManager ?: new EventManager())
);
break;
case ($conn instanceof Connection):
if ($eventManager !== null && $conn->getEventManager() !== $eventManager) {
throw ORMException::mismatchedEventManager();
}
break;
default:
throw new \InvalidArgumentException("Invalid argument: " . $conn);
}
// return your instance of em
return new MyEntityManager($conn, $config, $conn->getEventManager());
}
Error that you see is the fact that you have the wrong settings in the config.yml for doctrine. See reference.

API-Platform will generate Swagger/OpenAPI route documentation and then below documentation for the Schemas (AKA Models) (the docs show them as "Models" but current versions such as 2.7 show them as "Schemas").
Where is the content generated to show these schemas/models? How can some be removed? The functionality to display them is part of Swagger-UI, but API-Platform must be responsible for providing the JSON configuration and thus which to change API-Platform and not Swagger-UI. Note that this post shows how to add a schema but not how to remove one. Is there any documentation on the subject other than this which doesn't go into detail?
As seen by the output below, I am exposing AbstractOrganization, however, this class is extended by a couple other classes and is not meant to be exposed, but only schemas for the concrete classes should be exposed. Note that my AbstractOrganization entity class is not tagged with #ApiResource and is not shown in the Swagger/OpenAPI routing documentation but only the schema/model documentation.
Thank you
I am pretty certain there are better ways to implement this, however, the following will work and might be helpful for others.
<?php
declare(strict_types=1);
namespace App\OpenApi;
use ApiPlatform\Core\OpenApi\Factory\OpenApiFactoryInterface;
use ApiPlatform\Core\OpenApi\OpenApi;
use ApiPlatform\Core\OpenApi\Model\Paths;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
class OpenApiRouteHider implements OpenApiFactoryInterface {
public function __construct(private OpenApiFactoryInterface $decorated, private TokenStorageInterface $tokenStorage)
{
}
public function __invoke(array $context = []): OpenApi
{
$openApi = $this->decorated->__invoke($context);
$removedPaths = $this->getRemovedPaths();
$paths = new Paths;
$pathArray = $openApi->getPaths()->getPaths();
foreach($openApi->getPaths()->getPaths() as $path=>$pathItem) {
if(!isset($removedPaths[$path])) {
// No restrictions
$paths->addPath($path, $pathItem);
}
elseif($removedPaths[$path]!=='*') {
// Remove one or more operation
foreach($removedPaths[$path] as $operation) {
$method = 'with'.ucFirst($operation);
$pathItem = $pathItem->$method(null);
}
$paths->addPath($path, $pathItem);
}
// else don't add this route to the documentation
}
$openApiTest = $openApi->withPaths($paths);
return $openApi->withPaths($paths);
}
private function getRemovedPaths():array
{
// Use $user to determine which ones to remove.
$user = $this->tokenStorage->getToken()->getUser();
return [
'/guids'=>'*', // Remove all operations
'/guids/{guid}'=>'*', // Remove all operations
'/tenants'=>['post', 'get'], // Remove only post and get operations
'/tenants/{uuid}'=>['delete'], // Remove only delete operation
'/chart_themes'=>'*',
'/chart_themes/{id}'=>['put', 'delete', 'patch'],
];
}
}
I am currently trying to denormalize an array, which came out of an API as a JSON response and was JSON decoded.
The problem is, that I want it to be denormalized into a class and one of the properties is another class.
It feels like it should be possible to get such an easy job done with the Symfony denormalizer, but I always get the following exception:
Failed to denormalize attribute "inner_property" value for class "App\Model\Api\Outer": Expected argument of type "App\Model\Api\Inner", "array" given at property path "inner_property".
My denormalizing code looks like that:
$this->denormalizer->denormalize($jsonOuter, Outer::class);
The denormalizer is injected in the constructor:
public function __construct(DenormalizerInterface $denormalizer) {
The array I try to denormalize:
array (
'inner_property' =>
array (
'property' => '12345',
),
)
Finally the both classes I try to denormalize to:
class Outer
{
/** #var InnerProperty */
private $innerProperty;
public function getInnerProperty(): InnerProperty
{
return $this->innerProperty;
}
public function setInnerProperty(InnerProperty $innerProperty): void
{
$this->innerProperty = $innerProperty;
}
}
class InnerProperty
{
private $property;
public function getProperty(): string
{
return $this->property;
}
public function setProperty(string $property): void
{
$this->property = $property;
}
}
After hours of searching I finally found the reason. The problem was the combination of the "inner_property" snake case and $innerProperty or getInnerProperty camel case. In Symfony 5 the camel case to snake case converter is not enabled by default.
So I had to do this by adding this config in the config/packages/framework.yaml:
framework:
serializer:
name_converter: 'serializer.name_converter.camel_case_to_snake_case'
Here is the reference to the Symfony documentation: https://symfony.com/doc/current/serializer.html#enabling-a-name-converter
Alternatively I could have also add a SerializedName annotation to the property in the Outer class:
https://symfony.com/doc/current/components/serializer.html#configure-name-conversion-using-metadata
PS: My question was not asked properly, because I didn't changed the property and class names properly. So I fixed that in the question for future visitors.
I have a controller:
public function getAllItemsAction()
{
$content = $this->getDoctrine()->getRepository(Item::class)->findAll();//<-(1)--THIS TO REPOSITORY
if ($content === NULL) {
return new View("Items not found", Response::HTTP_NOT_FOUND);
}
return new View($content,Response::HTTP_OK);
}
How can I move this line (1) to the repository and then use this method from the repository in the controller?
The line you highlighted is actually not related from Doctrine: you are getting a service from the Dependency Injection container, and then calling a method on it.
What may bothers you is that you are using an alias (getDoctrine()) and the registry from Doctrine, which is there for conveniency.
But actually you could also declare you repository as a service and do this: $this->get('item_repository)->findAll()`.
We're building a REST API in Symfony and in many Controllers we're repeating the same code for parsing and settings properties of objects/entities such as this:
$title = $request->request->get('title');
if (isset($title)) {
$titleObj = $solution->getTitle();
$titleObj->setTranslation($language, $title);
$solution->setTitle($titleObj);
}
I'm aware that Symfony forms provide this functionality, however, we've decided in the company that we want to move away from Symfony forms and want to use something simplier and more customisable instead.
Could anybody please provide any ideas or examples of libraries that might achieve property parsing and settings to an object/entity? Thank you!
It seems like a good use case for ParamConverter. Basically it allows you, by using #ParamConverter annotation to convert params which are coming into your controller into anything you want, so you might just create ParamConverter with code which is repeated in many controllers and have it in one place. Then, when using ParamConverter your controller will receive your entity/object as a parameter.
class ExampleParamConverter implements ParamConverterInterface
{
public function apply(Request $request, ParamConverter $configuration)
{
//put any code you want here
$title = $request->request->get('title');
if (isset($title)) {
$titleObj = $solution->getTitle();
$titleObj->setTranslation($language, $title);
$solution->setTitle($titleObj);
}
//now you are setting object which will be injected into controller action
$request->attributes->set($configuration->getName(), $solution);
return true;
}
public function supports(ParamConverter $configuration)
{
return true;
}
}
And in controller:
/**
* #ParamConverter("exampleParamConverter", converter="your_converter")
*/
public function action(Entity $entity)
{
//you have your object available
}
I'm using ACL in Symfony 2.1, and I need to create a new SecurityIdentity, so that my ACL can be set in function of some sort of groups.
Picture the following situation: there are groups with users (with different roles) that each have user information. In group 1, users with the ROLE_ADMIN can't edit other users from the same group's information, but in group 2, users with ROLE_ADMIN can edit others information.
So basically my ACL will vary in function of what group the user is in.
I thought I'd start solving this problem with the creation of a new "GroupSecurityIdentity". However the class itself doesn't suffice, as I get this exception when I use it:
$sid must either be an instance of UserSecurityIdentity, or RoleSecurityIdentity.
My question is: how do I "register" my new SecurityIdentity so I can use it as RoleSecurityIdentity and UserSecurityIdentity?
What better ways are there to implement a system similar to this I want to do?
2 years ago I went down that path, it turned out to be a bad decision. Modifying the ACL system is difficult and might cause problems when updating Symfony. There are at least 2 better solutions. I'll list them all so you can decide which best suits your needs.
New security identity
I'm using the GroupInterface from FOSUserBundle, but I guess you could use your own too. The following files need to be added:
AclProvider.php
The method to change is private - the whole file has to be copied, but the only change has to be made to hydrateObjectIdentities
GroupSecurityIdentity.php
MutableAclProvider.php
We have to duplicate the whole file as it must extend AclProvider, but we're using a custom one and can't therefore extend the stock MutableAclProvider. The methods changed are getInsertSecurityIdentitySql and getSelectSecurityIdentityIdSql.
SecurityIdentityRetrievalStrategy.php
Next up: rewire the dependency injection container by providing the following parameters:
<parameter key="security.acl.dbal.provider.class">
Acme\Bundle\DemoBundle\Security\Acl\Dbal\MutableAclProvider
</parameter>
<parameter key="security.acl.security_identity_retrieval_strategy.class">
Acme\Bundle\DemoBundle\Security\Acl\Domain\SecurityIdentityRetrievalStrategy
</parameter>
Time to cross fingers and see whether it works. Since this is old code I might have forgotten something.
Use roles for groups
The idea is to have group names correspond to roles.
A simple way is to have your User entity re-implement UserInterface::getRoles:
public function getRoles()
{
$roles = parent::getRoles();
// This can be cached should there be any performance issues
// which I highly doubt there would be.
foreach ($this->getGroups() as $group) {
// GroupInterface::getRole() would probably have to use its
// canonical name to get something like `ROLE_GROUP_NAME_OF_GROUP`
$roles[] = $group->getRole();
}
return $roles;
}
A possible implementation of GroupInterface::getRole():
public function getRole()
{
$name = $this->getNameCanonical();
return 'ROLE_GROUP_'.mb_convert_case($name, MB_CASE_UPPER, 'UTF-8');
}
It's now just a matter of creating the required ACE-s as written in the cookbook article.
Create a voter
Finally, you could use custom voters that check for the presence of specific groups and whether the user has access to said object. A possible implementation:
<?php
namespace Acme\Bundle\DemoBundle\Authorization\Voter;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Core\Authorization\Voter\VoterInterface;
class MySecureObjectVoter implements VoterInterface
{
/**
* {#inheritDoc}
*/
public function supportsAttribute($attribute)
{
$supported = array('VIEW');
return in_array($attribute, $supported);
}
/**
* {#inheritDoc}
*/
public function supportsClass($class)
{
return $class instanceof GroupableInterface;
}
/**
* {#inheritDoc}
*/
public function vote(TokenInterface $token, $object, array $attributes)
{
$result = VoterInterface::ACCESS_ABSTAIN;
if (!$object instanceof MySecureObject) {
return VoterInterface::ACCESS_ABSTAIN;
}
foreach ($attributes as $attribute) {
if (!$this->supportsAttribute($attribute)) {
continue;
}
// Access is granted, if the user and object have at least 1
// group in common.
if ('VIEW' === $attribute) {
$objGroups = $object->getGroups();
$userGroups = $token->getUser()->getGroups();
foreach ($userGroups as $userGroup) {
foreach ($objGroups as $objGroup) {
if ($userGroup->equals($objGroup)) {
return VoterInterface::ACCESS_GRANTED;
}
}
}
return voterInterface::ACCESS_DENIED;
}
}
}
}
For more details on voters please refer to the cookbook example.
I would avoid creating a custom security identity. Use the two other methods provided. The second solution works best, if you will be having lots of records and each of them must have different access settings. Voters could be used for setting up simple access granting logic (which most smaller systems seem to fall under) or when flexibility is necessary.
I write my answer here to keep a track of this error message.
I implemented group support with ACL and i had to hack a bit the symfony core "MutableAclProvider.php"
protected function getSelectSecurityIdentityIdSql(SecurityIdentityInterface $sid)
{
if ($sid instanceof UserSecurityIdentity) {
$identifier = $sid->getClass().'-'.$sid->getUsername();
$username = true;
} elseif ($sid instanceof RoleSecurityIdentity) {
$identifier = $sid->getRole();
$username = false;
}else {
//throw new \InvalidArgumentException('$sid must either be an instance of UserSecurityIdentity, or RoleSecurityIdentity.');
$identifier = $sid->getClass().'-'.$sid->getGroupname();
$username = true;
}
return sprintf(
'SELECT id FROM %s WHERE identifier = %s AND username = %s',
$this->options['sid_table_name'],
$this->connection->quote($identifier),
$this->connection->getDatabasePlatform()->convertBooleans($username)
);
}
Even if the provided object is not an instance of UserSecurityIdentity or RoleSecurityIdentity it return a value. So now i can use a custom "GroupSecurityIdentity"
It's not easy to put in place but was much adapted to my system.
