When I run a schema update it successfully updates the schemas for my entities, but if there are any 'non-doctrine' tables in the database it deletes them. Unfortunately, these other tables are required for the 3rd party CMS I'm using.
Is there a way to tell doctrine to update the schema for certain entities (or all of them) without deleting anything else?
Below is my existing update code. The $classes array contains all the meta data for entity classes found in several different plugins.
//$em is an instance of EntityManager
//Psuedo Code
$classes = array(
$em->getClassMetadata('class1'),
$em->getClassMetadata('class2'),
$em->getClassMetadata('class3'),
$em->getClassMetadata('class4'),
$em->getClassMetadata('class5'),
);
//Real Code
$st = new Doctrine\ORM\Tools\SchemaTool( $em );
if ($classes)
$st->updateSchema($classes);
This gets all of the update sql but parses out any drop statements:
$sql = $st->getUpdateSchemaSql( $classes );
$count = count($sql);
for($i=0; $i<$count; $i++)
{
if(substr($sql[$i], 0, 4) == 'DROP')
unset($sql[$i]);
}
foreach($sql as $statement)
{
$em->getConnection()->exec( $statement );
}
You could run the schema tool with --dump-sql instead of --force, copy and paste the output from --dump-sql and run it on your database manually (of course removing the DROP statements for the tables you want to preserve.)

In Symfony3 I'm running
php app/console generate:doctrine:entity --entity=AcmeBlogBundle:Post
It creates 2 files: Post (in entity folder) and PostRepository (in repository folder extending \Doctrine\ORM\EntityRepository)
Everything is fine until I try to run the following repository-custom-function in my controller
$rir = $this->getDoctrine()->getRepository("AcmeBlogBundle:Post");
$replacementInstruction = $rir->getOneBy(
array("id" => 6)
);
My custom repository function is as follow
public function getOneBy($option)
{
$alias = "p";
$fields = $this->prepareRequestSelectFields("p");
$qb = $this->createQueryBuilder('Post');
$qb->select($fields)
->from('AcmeBlogBundle:Post', $alias)
->where($alias . '.id = :id')
->setParameter('id', 6)
;
$result = $qb->getQuery()->getResult();
}
private function prepareRequestSelectFields($alias)
{
return $alias. ".id";
}
In my database there are 10 posts with id from 1 to 10, so I expect it to return 1 result, however it return correct Post (id 6) 10 times
Why is that?
p.s. if I move the query builder to a custom service wrapper e.g. PostManager it works just fine (returning 1)
This doesn't really answer my question but apparently createQueryBuilder() in EntityRepository and in EntityManager are different, thanks to https://maltronic.io/2014/12/22/doctrine-createquerybuilder-entitymanager-vs-entityrepository/
So in my EntityRepository it should be
...
$qb = $this->createQueryBuilder('p'); // this should be the alias
$qb->select($fields)
// ->from('AcmeBlogBundle:Post', $alias) // remove this
->where($alias . '.id = :id')
->setParameter('id', 6)
;
...
Personally I dislike how 2 different functions has the same name, but I guess it's fine because one is from Doctrine and one is from Symfony. They are decoupled
edit Actually I might be wrong, they are both from Doctrine ... sigh
Still tho, it doesn't answer why in my original code, it returns multiple time
What about getSingleResult() rather than getResult() ? And you should maybe use the doctrine method findOneBy()
You can use the helper methods provided by the repositories, allowing you to fetch one or multiples entities from repositories with dynamic method names, in your case you want to fetch one post by id:
//fetch one
$replacementInstruction = $this->getDoctrine()->getRepository("AcmeBlogBundle:Post")->findOneById(6);
For information, fetching all entities is done with ->findByProperty
I'm running into a problem with the Doctrine Paginator.
In my repository I have a function to retrieve a specific dataset.
I use the querybuilder for this:
{myEntityRepository}->createQueryBuilder($alias)
In order to select only specific fields I use the following:
if (count($selectFields) > 0) {
$qb->resetDQLPart('select');
foreach ($selectFields as $selectField) {
$qb->addSelect($alias . '.' . $selectField);
}
}
This works fine when I retrieve the whole set like this:
$query = $qb->getQuery();
$data = $query->getResult(AbstractQuery::HYDRATE_ARRAY);
But it fails when I use the paginator:
$paginator = new Paginator($qb, $fetchJoinCollection = false);
$total = $paginator->count(),
$data = $paginator->getQuery()->getResult(AbstractQuery::HYDRATE_ARRAY)
I get the error:
Not all identifier properties can be found in the ResultSetMapping:
relationID\vendor\doctrine\orm\lib\Doctrine\ORM\Query\Exec\SingleSelectExecutor.php(38)
Question: Why does the paginator fail when I select only specific fields?
Am I overlooking something? Or am I doing it wrong all together?
i am using this solution.
add use statements
use Zend\Paginator\Paginator;
use DoctrineORMModule\Paginator\Adapter\DoctrinePaginator as DoctrineAdapter;
use Doctrine\ORM\Tools\Pagination\Paginator as ORMPaginator;
in your action
$viewModel = new ViewModel();
$entityManager = $this->getServiceLocator()
->get('Doctrine\ORM\EntityManager');
$queryBuilder = $entityManager
->createQueryBuilder();
$queryBuilder->add('select', new Expr\Select(array('t.id', 't.name')));
$queryBuilder->add('from', 'Application\Entity\Table t');
$adapter = new DoctrineAdapter(
new ORMPaginator(
$queryBuilder
)
);
$paginator = new Paginator($adapter);
$paginator->setDefaultItemCountPerPage(20);
$page = (int)$this->params()->fromQuery('page');
if($page) $paginator->setCurrentPageNumber($page);
$viewModel->results = $paginator;
return $viewModel;
Doctrine is trying to hydrate a relationship outlined by your YAML file, using a field that doesn't exist because you've excluded it from your SELECT statement. Take a look at your mapping file to figure out what you need to add back in.
I would think that it's only complaining with the Paginator because the field is not being accessed (and therefore not being lazy-loaded) when you don't use the Paginator.
As an aside (and with zero understanding of your stack, so YMMV) I would avoid making a habit of SELECTing reduced result sets, as you'll find yourself running into odd issues like this all the time. If you do need extra performance, you'd be better off putting a good old caching layer in place...
Actually using Zend Framework 2, I am looking for a way to implement a performant ACL strategy based on a database.
The whole idea is to directly filter the DQL queries depending on the currently logged in user, and it's permissions.
I found an implementation of this mecanisme in Symfony 2 http://symfony.com/doc/current/cookbook/security/acl_advanced.html, in this case one table seems to store for each user if he has access to a single row, so we can easily dynamically load only allowed rows by joining this table.
To synthesize,I am looking for a way to define access rules to entities based on criterias, but want to be able to get results in a single query to be able to do some ordering, and pagination.
Are there any ZF2 modules to resolve this case ?
It looks like integrating the SF2 security component as standalone is not an option: Security component from Symfony 2.0 as standalone
You have to use doctrine filter for load things for current member
example of my codes adding the filter for member query :
$em = $sm->get('doctrine.entitymanager.orm_default');
$ormconfig = $sm->get('doctrine.configuration.orm_default');
$ormconfig->addFilter("member", "\PatrickCore\Script\ORM\Functional\MemberAccessFilter");
//
$currentUser = $membersService->getCurrentUser();
$uid = $currentUser->getId();
$filter = $em->getFilters()->enable("member");
$filter->setParameter('member', $uid);
and this file \PatrickCore\Script\ORM\Functional\MemberAccessFilter :
<?php
namespace PatrickCore\Script\ORM\Functional;
use Doctrine\ORM\Mapping\ClassMetaData,
Doctrine\ORM\Query\Filter\SQLFilter;
class MemberAccessFilter extends SQLFilter
{
public function addFilterConstraint(ClassMetadata $targetEntity, $targetTableAlias)
{
// Check if the entity implements the LocalAware interface
if (!$targetEntity->reflClass->implementsInterface('\PatrickCore\Entity\MemberAccessAware')) {
return "";
}
return $targetTableAlias.'.member_id = ' . $this->getParameter('member'); // getParameter applies quoting automatically
}
}
I have been wondering why my mappings and the controller actions are not working. For this I need to refer to my previous post, where I have described my entities and database schema, which can be found here. I need to start a new post since there were no further updates and I thought this the only way to get attention of the Doctrine + Zend Pros.
As described in my previous post, I have a Zend Form, the user can enter teamId and teamName, further he has the choice to select multiple players from the drop down list on the form and can allocate players to the team. So basically that is my goal to achieve with Doctrine and Zend. For that I wrote my entities described in the previous post and right now I want to add the code from my controller to persist the entities.
Controller:
public function addAction()
{
$form = new TeamForm($this->getEntityManager());
$form->get('submit')->setAttribute('value', 'Add');
$request = $this->getRequest();
if ($request->isPost())
{
$team = new Team();
$player = new Player();
$teamPlayers = new TeamPlayer();
$form->setInputFilter($typeset->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid())
{
$team->populate($form->getData());
$teamPlayers->setPlayer($player);
$teamPlayers->setTeam($team);
$this->getEntityManager()->persist($teamPlayers);
$this->getEntityManager()->flush();
//Reroute to the index page once the data is successfully added
}
}
//return form array
return array(
'form' => $form
);
}
So that is basically what Im doing in my controller to save the entities into two tables (team Table and teamPlayer Table), as already the player Table is populated with data. So I want to add players to the team and assign that values in these two tables.
Right now I can see my form and when I enter the data and press submit nothing is happening, i can see the form with no action. When the data is successfully saved into the database then I reroute it to the index page which is not happening.
Any help would be appreciated, to point out the error Im making either in mapping section or in the controller side.
The official documentation especially from Doctrine 2 is too global and is particulary not that clear for my requirement.
let's try to solve it by updating this answer by steps :
step 1 :
your words implied to me that , you might have some issues in from validation , so lets check if you are passing this $form->isValid()
if ($form->isValid())
{
$team->populate($form->getData());
$teamPlayers->setPlayer($player);
$teamPlayers->setTeam($team);
$this->getEntityManager()->persist($teamPlayers);
$this->getEntityManager()->flush();
//Reroute to the index page once the data is successfully added
}else{
var_dump($form->getMessages());
}
I can also suggest you to use doctrine commandline : doctrine orm:validate-schema , this command will help you to check if your entity mapping is ok plus your database mapping is also okay , i see it as handy to to debug your doctrine2 entity
ps : I havn't read your entities in depth yet
I'm looking at Caching and how to use it in Doctrine.
I've got the following in my Zend Framework Bootstrap.php:
// Build Configuration
$orm_config = new \Doctrine\ORM\Configuration();
// Caching
$cacheOptions = $options['cache']['backendOptions'];
$cache = new \Doctrine\Common\Cache\MemcacheCache();
$memcache = new Memcache;
$memcache->connect($cacheOptions['servers']['host'], $cacheOptions['servers']['port']);
$cache->setMemcache($memcache);
$orm_config->setMetadataCacheImpl($cache);
$orm_config->setQueryCacheImpl($cache);
$orm_config->setResultCacheImpl($cache);
I'm running a very simple query on my DB using:
self::_instance()->_em->getRepository('UserManagement\Users')->find('1');
And I'm not sure if I'm using caching properly, because with it on (as
per the above config) the query seems to take twice as long to execute
as with it disabled, is this right?
Thanks in advance,
Steve
I seem to have sorted this myself, sort of related to enter link description here. Basically, from what I understand a repository query like:
self::_instance()->_em->getRepository('UserManagement\Users')->find('1');
Will not cache the results. If the same query is executed again throughout the script processing, it will not perform the search and use the result it has in memory - this isn't the same as real caching, in my case using Memcache.
The only way to achieve this, is to override the Doctrine EntityRepository find() method in a custom repository with something like:
public function find($id)
{
// Retrieve an instance of the Entity Manager
$qb = $this->getEntityManager()->createQueryBuilder();
$qb->select('u')
->from('UserManagement\Users', 'u')
->where('u.id = :id')
->setParameter('id', $id);
$query = $qb->getQuery();
$query->useResultCache(TRUE);
$result = $query->getSingleResult();
return $result;
}
Notably, the most important line from the above is $query->useResultCache(TRUE); - this informs the Application to cache the results.
Hope this helps.
