consider these two entities:
/** #Entity */
class String {
/** #Id #Column(type="integer")
* #GeneratedValue
*/
public $id;
/** #Column(length=255) */
public $name;
/**
* #OneToMany(targetEntity="StringTranslation", mappedBy="owner") */
public $translations;
}
/** #Entity */
class StringTranslation {
/** #Id #Column(type="integer")
* #GeneratedValue
*/
public $id;
/* #ManyToOne(targetEntity="String", inversedBy="translations")
* #JoinColumn(name="foreignId", referencedColumnName="id") */
public $owner;
/** #Column(length=2) */
public $lang;
/** #Column(length=255) */
public $translation;
}
When I get the query using
$query = qb()->select(array('s', 't'))
->from('String', 's')
->leftJoin('s.translations', 't')
->getQuery()
->getSQL();
I get this result:
SELECT s0_.id AS id0, s0_.name AS name1, s1_.id AS id2, s1_.foreign_id
AS foreign_id3, s1_.lang AS lang4, s1_.translation AS translation5
FROM String s0_ LEFT JOIN
Why is the left join not being generated?
When i try to get the result of the query with
$query = qb()->select(array('s', 't'))
->from('String', 's')
->leftJoin('s.translations', 't')
->getQuery()
->getArrayResult();
this error comes up:
Fatal error: Uncaught exception 'PDOException' with message
'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an
error in your SQL syntax
How can this problem be solved?
Found it! It all boils down to a typo. Annotations must start with /** and not with /*. Changing the line
/* #ManyToOne(targetEntity="String", inversedBy="translations")
to
/** #ManyToOne(targetEntity="String", inversedBy="translations")
solved the problem!

I have a problem with saving data in Database.I have two tables which are created with Doctrine Entities. My Entities are:
<?php

My tables:
files:
cic_case_file:
I'd like to save data in table CicCaseFile by code:
$cicFile = new CicCaseFile();
cicFile->setCaseId($caseId);
$cicFile->setFileId($fileId);
$this->entityManager->persist($cicFile);
$this->entityManager->flush();
Something is wrong with my Entities, but I don't know what. Could someone help me with that? I would be very greatful. Best regards.
This is what I used to follow if I am in your position.
Your File Entity must only have id, path, extension, original_name, hash_name properties and methods, you can internally use any conversion methods
Your CicCaseFile Entity must only have id, case_id, file_id properties and methods, you can internally use any conversion methods
So what must be your approach while inserting the data is, first you need to insert the data for your parent table ie file table then its children table ie cic_case_file table
$em = $this->getDoctrine()->getManager(); /* In Symfony Framework */
$fileObj = new File();
$fileObj->setPath($path);
$fileObj->setExtension($extension);
$fileObj->setOriginalName,($originalName);
$fileObj->setHashName($hashName);
$em->persist($fileObj);
$em->flush();
/* So once you flush here it fileObj will be having the last inserted object which you can use to store in child table */
$cicCaseFileObj = new CicCaseFile();
$cicCaseFileObj->setFile($fileObj); /* $fileObj which was inserted above */
$cicCaseFileObj->setCaseId($caseObj); /* Same as $fileObj as inserted above in case if this is from different table */
$em->persist($cicCaseFileObj);
$em->flush();
if caseId is inserted in different saveMethod then first you need to fetch the object and then give it to the above object as follows
$caseId = 10; /* This you may get from else where */
$caseObj = $em->getRepository('BundleName:Case')->find($caseId);
/* Make sure your case_id is nullable or not */
$cicCaseFileObj = new CicCaseFile();
$cicCaseFileObj->setFile($fileObj);
if($caseObj){
$cicCaseFileObj->setCaseId($caseObj);
}
$em->persist($cicCaseFileObj);
$em->flush();
Happy Coding!
When using class table inheritance with multiple levels in doctrine :
Account->User->Dealer
(Dealer inherits from User, User from Account)
Account has the discriminator column and mapping. When persisting a new Dealer entity I get a foreign key error because there is no row in the User table.
So the order in which the insert statements are executed is:
1) Insert into Account
2) Insert into Dealer (which causes the error)
3) insert into User
Can someone help me thanks in advance
this is my configuration :
/**
* #Table(name="Account")
* #Entity
* #InheritanceType("JOINED")
* #DiscriminatorColumn(name="discr", type="string")
* #DiscriminatorMap({"Account" = "Default_Model_Account","User" = "Default_Model_User","Dealer" = "Default_Model_Dealer"})
*/
class Default_Model_Account {
/**
* #id #column(name="accountID",type="integer")
* #GeneratedValue(strategy="AUTO")
*/
protected $accountID;
/**
* #column(name="email",type="string")
*
*/
protected $email;
}
/**
* #Table(name="User")
* #Entity
*/
class Default_Model_User extends Default_Model_Account{
/**
* #column(name="firstName",type="string")
*/
protected $firstName;
}
/**
* #Entity
* #Table(name="Dealer")
*
*/
class Default_Model_Dealer extends Default_Model_User{
/**
* #column(name="type",type="string")
*/
protected $type;
}
I started using Doctrine and ran into trouble immediately. I have an entity defined as follows:
namespace AdminModule;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="admin_user")
*/
class User extends \Nette\Object
{
/**
* #ORM\Id
* #ORM\Column(type="string", name="guid")
* #var string
*/
protected $id;
/**
* #ORM\Column(type="string")
* #var string
*/
protected $username;
/**
* #ORM\Column(type="string")
* #var string
*/
protected $password;
/**
* #ORM\Column(type="string")
* #var string
*/
protected $email;
/**
* #ORM\Column(type="datetime")
* #var datetime
*/
protected $registered;
/**
* #ORM\Column(type="datetime")
* #var datetime
*/
protected $last_login;
}
If I call
$u = $this->em->getRepository('AdminModule\User')->createQueryBuilder()
->select('u.username, u.id')
->from('AdminModule\User', 'u');
I get the RuntimeException stating that identifier property "id" is missing. However, when I run the above code with getQuery() and execute() it, it returns the result I want.
Can you help me out? If more information is needed, just tell me. Thank you.
So I've read the following article.
I've done something similar with my own entities and am trying to create a DQL.
DQL:
$em = $this->getDoctrine()->getManager();
$query = $em->createQuery(
'SELECT s,st,tt
FROM CrmClientBundle:Session s
INNER JOIN s.session_treatments st
INNER JOIN st.treatment_type_id tt
WHERE s.client_id = ' . $id
);
$sessions = $query->getResult();
I receive the following error though:
[Semantical Error] line 0, col 152 near 'tt
': Error: Class Crm\ClientBundle\Entity\TreatmentType has no association named
treatment_type_id
However if I remove the second join and check the symfony profiler it creates the following query which seems to me that I have created my entities properly:
SELECT
s0_.id AS id0,
s0_.client_id AS client_id1,
s0_.date AS date2,
s0_.session_id AS session_id3,
s0_.session_type AS session_type4,
s0_.session_cost AS session_cost5,
s0_.products_bought AS products_bought6,
s0_.products_cost AS products_cost7,
s0_.total_cost AS total_cost8,
s0_.total_paid AS total_paid9,
s0_.notes AS notes10,
t1_.id AS id11,
t1_.type AS type12,
t1_.cost AS cost13,
t1_.category_id AS category_id14
FROM
sessions s0_
INNER JOIN session_treatments s2_ ON s0_.id = s2_.session_id
INNER JOIN treatment_types t1_ ON t1_.id = s2_.treatment_type_id
WHERE
s0_.client_id = 1
Crm\ClientBundle\Session.php:
/**
* #ORM\Entity
* #ORM\Table(name="sessions")
*/
class Session {
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/** #ORM\Column(type="integer") */
private $client_id;
/** #ORM\Column(type="date") */
private $date;
/**
* **
* #ORM\ManyToMany(targetEntity="TreatmentType")
* #ORM\JoinTable(name="session_treatments",
* joinColumns={#ORM\JoinColumn(name="session_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="treatment_type_id", referencedColumnName="id ", unique=true)}
* )
*/
private $session_treatments;
/**
* Constructor
*/
public function __construct()
{
$this->session_treatments = new ArrayCollection();
}
}
Crm\ClientBundle\TreatmentType.php:
/**
* #ORM\Entity
* #ORM\Table(name="treatment_types")
*/
class TreatmentType {
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/** #ORM\Column(type="string", length=255) */
private $type;
/** #ORM\Column(type="decimal") */
private $cost;
}
You have 2 entities and you are trying to retrieve 3 entities. The second join is unnecessary. It's only needed if TreatmentType has yet another relationship (other then the one with Session). For clarification:
$em = $this->getDoctrine()->getManager();
$query = $em->createQuery(
'SELECT s,st,tt
FROM CrmClientBundle:Session s // <-- s is your Session
INNER JOIN s.session_treatments st // <-- st is your TreatmentType
INNER JOIN st.treatment_type_id tt <-- TreatmentType does not have a property $treatement_type_id that points to non-defined relationship. tt would be your 3rd entity.
WHERE s.client_id = ?1'
);
$query->setParameter(1, $id);
$sessions = $query->getResult();
Bonus: used bound a parameter -- helps against SQL injection and speeding up your query in the future
I have two tables/entities client and site that have a many to many relationship combined by a join table client_site. Here are how my entities are setup.
Here is the client table entity
/**
* #Entity
* #Table(name="client")
*/
class Client
{
/**
* #Id #Column(type="bigint")
* #GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ManyToMany(targetEntity="Site", inversedBy="clients")
* #JoinTable(name="client_site",
* joinColumns={#JoinColumn(name="c_id", referencedColumnName="id")},
* inverseJoinColumns={#JoinColumn(name="s_id", referencedColumnName="id")}
* )
*/
private $sites;
And the site table entity
/**
* #Entity
* #Table(name="site")
*/
class Site
{
/**
* #Id #Column(type="bigint")
* #GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ManyToMany(targetEntity="Client", mappedBy="sites")
*/
private $clients;
This is the client_site table entity
/**
* #Entity
* #Table(name="client_site",indexes={#index(name="FK_client_site",columns={"c_id"}),#index(name="FK_client_site_2",columns={"s_id"})})
*/
class ClientSite
{
/**
* #Id
* #ManyToOne(targetEntity="Client", inversedBy="ClientSite")
*/
private $client;
/**
* #Id
* #ManyToOne(targetEntity="Site", inversedBy="ClientSite")
*/
private $site;
This is the query I am trying to run
$query = Zend_Registry::get('em')
->createQuery('SELECT c, s
FROM Application\Models\Client c
JOIN c.sites s
WHERE c.is_active = 1');
$clients = $query->getResult();
And this is my error
No identifier/primary key specified for Entity 'Application\Models\ClientSite'. Every Entity must have an identifier/primary key.
I put the #Id on both fields in the ClientSite entity, as they are the composite primary keys for my joiner table. Can this not be done in Doctrine2? If it can't, what are my alternative options.
If you CAN do this, what have I done incorrectly?
This isn't currently supported by Doctrine 2.
However, they are working on adding support for this in an experimental branch. Apparently this might be included in the 2.1 release if it works without issues.
