I'm facing a problem while using $em->flush ();
the object $education is persisted throw $em->persist ($education).
The location is an entity in my project and is related to the education entity throw a many-to-one relation.
The error box Contain:
A new entity was found through the relationship 'XBundle\Entity\Education#location' that was not configured to cascade persist operations for entity: NewYork. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example #ManyToOne(..,cascade={"persist"}).
How can i solve this issue?
Use cascade={"persist"} on the relation. E.g.:
/**
* #ORM\OneToOne(targetEntity="Foo\Bundle\Entity\User", mappedBy="bar", cascade={"persist"})
*/
protected $foo;
In Doctrine 2, cascade persistence doesn't happen automatically. Instead, you need to explicitly indicate that you want it. If you are using docblock annotations to specify your DB schema, that's achieved by adding the cascade attribute to your #ManyToOne association:
<?php
namespace XBundle\Entity;
/**
* #Entity
*/
class Education
{
//...
/**
* #ManyToOne(targetEntity="Location", cascade={"persist"})
*/
protected $location;
//...
}

I have 3 Entity Client, Classes, Fournitures. Client has an OnetoMany relations with Fournitures and Fourniteurs has a ManytoOne relations with Classes, to do this I make a nest fields for the Client form as here is the ClientType:
$builder->add('nom')
->add('adresse')
->add('idfournitures', FournituresType::class);
FournituresType
$builder->add('nom')
->add('value')
->add('prix')
->add('idclasses', ClassesType::class);
ClassesType
$builder->add('categories')
->add('famille');
the form is fine but the problem now is that during my newAction, it returns the error : A new entity was found through the relationship 'AppBundle\Entity\Fournitures#idclasses' that was not configured to cascade persist operations for entity. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example #ManyToOne(..,cascade={"persist"}).
and although i have already set up my entity Classes with cascade persist in Fournitures and also persisted in my newAction, the problem still persists.
/**
* #var \AppBundle\Entity\Classes
*
* #ORM\ManyToOne(targetEntity="AppBundle\Entity\Classes", cascade={"persist"})
* #ORM\JoinColumns({
* #ORM\JoinColumn(name="idclasses", referencedColumnName="idclasses", nullable=false)
* })
*/
private $idclasses;
NewAction
if ($form->isSubmitted() && $form->isValid()) {
$em->persist($client);
$em->persist($client->getIdfournitures());
$em->persist($client->getIdfournitures()->getIdclasses());
$em->flush();
}
I do not know if what I'm doing this with symfony or not, but I need help to solve the problem because I do not know what to do, thank you!
Add cascade persist to your oneToMany relation too.
I am getting two warnings about misconfigured entities in my Symfony 2 project. It runs fine in the development environment, but the production environment will not start and I suspect these misconfigured entities might be the reason.
It is the same error on both entities so I am only including one of them as an example.
BizTV\MediaManagementBundle\Entity\QrImage:
The field BizTV\MediaManagementBundle\Entity\QrImage#visits is on the inverse side of a bi-directional relationship, but the specified mappedBy association on the target-entity BizTV\MediaManagementBundle\Entity\QrVisit#QrImage does not contain the required 'inversedBy="visits"' attribute.
QrVisit entity:
class QrVisit
{
...
/**
* #var object BizTV\MediaManagementBundle\Entity\QrImage
*
* #ORM\ManyToOne(targetEntity="BizTV\MediaManagementBundle\Entity\QrImage")
* #ORM\JoinColumn(name="QrImage", referencedColumnName="id")
*/
protected $QrImage;
QrImage entity:
class QrImage
{
...
/**
* #ORM\OneToMany(targetEntity="BizTV\MediaManagementBundle\Entity\QrVisit", mappedBy="QrImage")
*/
private $visits;
I changed QrImage to include the inversedBy as below, but I probably did it wrong because I still get an error message, although a new one.
/**
* #ORM\OneToMany(targetEntity="BizTV\MediaManagementBundle\Entity\QrVisit", mappedBy="QrImage", inversedBy="visits")
*/
private $visits;
But this generates the error:
[Creation Error] The annotation #ORM\JoinColumn declared on property BizTV\UserBundle\Entity\UserGroup::$company does not have a property named "inversedBy". Available properties: name, referencedColumnName, unique, nullable, onDelete, columnDefinition, fieldName
If you want to establish a bi-directional ManyToOne / OneToMany relationship you'll have to put the mappedBy attribute on the OneToMany side like:
#ORM\OneToMany(targetEntity="BizTV\MediaManagementBundle\Entity\QrVisit", mappedBy="QrImage")
and the inversedBy on the ManyToOne side like:
#ORM\ManyToOne(targetEntity="BizTV\MediaManagementBundle\Entity\QrImage", inversedBy="visits")
that's all you need here. For your reference please check Doctrine doc
The error that you're getting refers to a different entity (UserGroup) but you can check them in the same fashion.
I'm actually learning Symfony3 and more precisely the Doctrine2 relation between objects and I was wondering if there is a default value for the cascade parameter when you don't explicite it.
I seen in tutorials when it's necessary to use the remove value that the parameter is not specified, but there is no explanation about this fact.
So I mean is this
/**
* #ORM\ManyToOne(targetEntity="UTM\ForumBundle\Entity\UtmWebsiteTopics")
* #ORM\JoinColumn(nullable=false)
*/
private $topic;
equivalent to that ?
/**
* #ORM\ManyToOne(targetEntity="UTM\ForumBundle\Entity\UtmWebsiteTopics", cascade={"remove"})
* #ORM\JoinColumn(nullable=false)
*/
private $topic;
Thank you for reading and I hope you'll be able to bring me an answer. :D
In short, those two snippets are not the same. If you were to want to delete a specific entity that has relations to others through FK, you would need to explicitly remove() the related entities to avoid Integrity Constraint Violations.
Examples of each
Not defining cascade={"remove"}
public function removeEntityAction($id)
{
// Get entity manager etc....
$myEntity = $em->getRepository("MyEntity")->findBy(["id" => $id]);
foreach($myEntity->getTopics() as $topic) {
$em->remove($topic);
}
$em->remove($myEntity);
}
Defining cascade={"remove"}
public function removeEntityAction($id)
{
// Get entity manager etc....
$myEntity = $em->getRepository("MyEntity")->findBy(["id" => $id]);
$em->remove($myEntity);
}

Doctrine - Removing Entities
I'm trying to get the following working:
I've got an entity like:
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use JMS\Serializer\Annotation as JMS;
/**
* Contact
*
* #ORM\Table()
* #ORM\Entity()
*/
class Contact
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* #ORM\ManyToOne(targetEntity="AppBundle\Entity\ServiceClient", inversedBy="contacts")
* #ORM\JoinColumn(name="service_client", referencedColumnName="service_client")
*
* #JMS\Type("AppBundle\Entity\ServiceClient")
* #JMS\SerializedName("serviceClient")
*/
private $serviceClient;
}
I'm sending the following JSON over an HTTP request (Post, it's a new Contact, no ID):
{
"name": "Lorem Ipsum",
"serviceClient": {"service_client": "ipsum"}
}
What I expect is for the JMS Serializer to parse that relationship, and leting me persist the Contact object like this:
<?php
$contact = $this->get('serializer')->deserialize(
$request->getContent(),
Contact::class, 'json'
);
$this->em->persist($contact);
$this->em->flush();
In fact I got that working (I swear it was working) but now it's giving me the follwing error:
A new entity was found through the relationship
'AppBundle\Entity\Contact#serviceClient' that was not configured to
cascade persist operations for entity:
AppBundle\Entity\ServiceClient#000000006fafb93e00007f122bd10320. To
solve this issue: Either explicitly call EntityManager#persist() on
this unknown entity or configure cascade persist this association in
the mapping for example #ManyToOne(..,cascade={\"persist\"}). If you
cannot find out which entity causes the problem implement
'AppBundle\Entity\ServiceClient#__toString()' to get a clue."
So it's tryign to persist the entity... a thing I do not want since the entity already exists. I just want Doctrine to put the reference, the foreign key.
Edit: It seems it's the constructor, if I set it to the doctrine_object_constructor it works like magic, the thing I do not understand is why it stop working in the first place.
Can anyone share any ideas or a cleaner way to do what I did?
jms_serializer.object_constructor:
alias: jms_serializer.doctrine_object_constructor
public: false
This problem happens when Doctrine cannot map your relationship to an existing record in the database, so it will try to create a new one with the data from the JSON object.
In your case, the JSON object: {"service_client": "ipsum"} cannot be mapped to an existing ServiceClient instance.
It's because the default JMS object constructor call the unserialize function (will be the one from your Entity if you defined this method) to construct the object, which mean this object will always be treated by Doctrine as new (has never been persisted).
By using doctrine_object_constructor, JMS will get the object from Doctrine. The object came from Doctrine not only have the attributes and methods you define in your entity, but also meta-data about whether it's an existing one, it's corresponding row from the database ( so Doctrine can detect update made on the record later and handle it), therefore Doctrine are able to avoid incorrect persisting.
Doctrine will try to persist the Contact with a reference of a ServiceClient entity given in the deserialization. In the entity definition at the level of the manyToOne definition you need to add :
#ORM\ManyToOne(targetEntity="AppBundle\Entity\ServiceClient", inversedBy="contacts", cascade={"persist"})
I have the following associations in my database (simplified version):
This is a Many-To-Many association but with an attribute on the joining table, so I have to use One-To-Many/Many-To-One associations.
I have a form where I can add as many relations as I want to one order item and create it at the same time (mainly inspired by the How to Embed a Collection of Forms tutorial from the documentation.
When I post the form, I get the following error:
Entity of type TEST\MyBundle\Entity\Relation has identity through
a foreign entity TEST\MyBundle\Entity\Order, however this entity
has no identity itself. You have to call EntityManager#persist() on
the related entity and make sure that an identifier was generated
before trying to persist 'TEST\MyBundle\Entity\Relation'. In case
of Post Insert ID Generation (such as MySQL Auto-Increment or
PostgreSQL SERIAL) this means you have to call EntityManager#flush()
between both persist operations.
I understand this error because Doctrine tries to persist the Relation object(s) related to the order since I have the cascade={"persist"} option on the OneToMany relation. But how can I avoid this behavior?
I have tried to remove cascade={"persist"} and manually persist the entity, but I get the same error (because I need to flush() order to get the ID and when I do so, I have the same error message).
I also tried to detach() the Relation objects before the flush() but with no luck.
This problem seems unique if 1) you are using a join table with composite keys, 2) forms component, and 3) the join table is an entity that is being built by the form component's 'collection' field. I saw a lot of people having problems but not a lot of solutions, so I thought I'd share mine.
I wanted to keep my composite primary key, as I wanted to ensure that only one instance of the two foreign keys would persist in the database. Using
this entity setup as an example
/** #Entity */
class Order
{
/** #OneToMany(targetEntity="OrderItem", mappedBy="order") */
private $items;
public function __construct(Customer $customer)
{
$this->items = new Doctrine\Common\Collections\ArrayCollection();
}
}
/** #Entity */
class Product
{
/** #OneToMany(targetEntity="OrderItem", mappedBy="product") */
private $orders;
.....
public function __construct(Customer $customer)
{
$this->orders = new Doctrine\Common\Collections\ArrayCollection();
}
}
/** #Entity */
class OrderItem
{
/** #Id #ManyToOne(targetEntity="Order") */
private $order;
/** #Id #ManyToOne(targetEntity="Product") */
private $product;
/** #Column(type="integer") */
private $amount = 1;
}
The problem I was facing, if I were building an Order object in a form, that had a collection field of OrderItems, I wouldn't be able to save OrderItem entity without having saved the Order Entity first (as doctrine/SQL needs the order id for the composite key), but the Doctrine EntityManager wasn't allowing me to save the Order object that has OrderItem attributes (because it insists on saving them en mass together). You can't turn off cascade as it will complain that you haven't saved the associated entities first, and you cant save the associated entities before saving Order. What a conundrum. My solution was to remove the associated entities, save Order and then reintroduce the associated entities to the Order object and save it again. So first I created a mass assignment function of the ArrayCollection attribute $items
class Order
{
.....
public function setItemsArray(Doctrine\Common\Collections\ArrayCollection $itemsArray = null){
if(null){
$this->items->clear();
}else{
$this->items = $itemsArray;
}
....
}
And then in my Controller where I process the form for Order.
//get entity manager
$em = $this->getDoctrine()->getManager();
//get order information (with items)
$order = $form->getData();
//pull out items array from order
$items = $order->getItems();
//clear the items from the order
$order->setItemsArray(null);
//persist and flush the Order object
$em->persist($order);
$em->flush();
//reintroduce the order items to the order object
$order->setItemsArray($items);
//persist and flush the Order object again ):
$em->persist($order);
$em->flush();
It sucks that you have to persist and flush twice (see more here Persist object with two foreign identities in doctrine). But that is doctrine for you, with all of it's power, it sure can put you in a bind. But thankfully you will only have to do this when creating a new object, not editing, because the object is already in the database.
You need to persist and flush the original before you can persist and flush the relationship records. You are 100% correct in the reason for the error.
I assume from the diagram that you are trying to add and order and the relation to the contact at the same time? If so you need to persist and flush the order before you can persist and flush the relationship. Or you can add a primary key to the Relation table.
I ended up creating a separated primary key on my Relation table (instead of having the composite one).
It looks like it is a dirty fix, and I am sure there is a better way to handle this situation but it works for now.
Here is my Relations entity:
/**
* Relation
*
* #ORM\Entity
*/
class Relation
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\ManyToOne(targetEntity="Contact", inversedBy="relation")
*/
protected $contact;
/**
* #ORM\ManyToOne(targetEntity="Order", inversedBy="relation")
*/
protected $order;
/**
* #var integer
*
* #ORM\Column(name="invoice", type="integer", nullable=true)
*/
private $invoice;
//Rest of the entity...
I then added the cascade={"persist"} option on the OneToMany relation with Order:
/**
* Orders
*
* #ORM\Entity
*/
class Order
{
/**
* #ORM\OneToMany(targetEntity="Relation", mappedBy="order", cascade={"persist"})
*/
protected $relation;
//Rest of the entity...
Et voilà!
