I'm trying to create the database tables using Symfony command's using the following line :
php app/console doctrine:schema:create
I obtain the following error :
[Doctrine\ORM\Mapping\MappingException]
No identifier/primary key specified for Entity "Cupon\CiudadBundle\Entity\Ciudad". Every Entity must have an identifier/primary key.
And it's the above class :
namespace Cupon\TiendaBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/** #ORM\Entity */
class Tienda
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue
*/
protected $id;
/** #ORM\ManyToOne(targetEntity="Cupon\CiudadBundle\Entity\Ciudad") */
protected $ciudad;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set ciudad
*
* #param \Cupon\CiudadBundle\Entity\Ciudad $ciudad
* #return Tienda
*/
public function setCiudad(\Cupon\CiudadBundle\Entity\Ciudad $ciudad = null)
{
$this->ciudad = $ciudad;
return $this;
}
/**
* Get ciudad
*
* #return \Cupon\CiudadBundle\Entity\Ciudad
*/
public function getCiudad()
{
return $this->ciudad;
}
public function __toString()
{
return $this->getNombre();
}
}
I don't understand whats really happen, because I put the ID for the class. Any help is appreciated.
Just check if the Ciudad Entity has an id
You should include the following annotations for example:
namespace Cupon\TiendaBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/** #ORM\Entity */
class Ciudad
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue
*/
protected $id;
//..

in my opinion you have this error because you already have datas in your database. When you try to add the foreign key on your user table, kcient_id is null. And in your definition, you specify nullable: false.
I suggest you proceed in two times.
Edit your annotation to nullable: true, update your database and link your client to klient
Re-edit your annotation to nullable: false, it should be ok
in my symfony app, i'm using embedded forms. In my case, an object "CompetenceGroupe" can have multiple objects "CompetenceItem", but an object "CompetenceItem" belongs to only one object "CompetenceGroupe", so the relation is manyToOne.
The form work perfectly, and I have two tables (one for each entity), and it's well saved in the database.
But when I select an CompetenceGroupe object with doctrine in my controller, I have all informations of the object, and he's got an empty "competenceItems" property, so I can't retrieve the childs object (CompetenceItem).
My "CompetenceGroupe" entity :

I think I have a missing annotation of the "competence_items" property in the CompetenceGroupe entity, but i'm really not sure ...
Thanks for your help !
A good practice may be to have a competence form, which would be call inside your competence group form
You may add a CollectionType as parrent and include query to search which competence already exist
There are some good example with post form type in symfony demo blog
Or you can use form events (onSubmit, preSubmit, etc...) to charge your entity with your required competence. This example show a message form which allow to choose friend from preset data, this is a good example.
You have tow choice , even to create a Many-To-One, Unidirectional , in this case , you need clean some code , take a look:
In CompetenceGroupe class :
class CompetenceGroupe
{
/**
* Many competence have One Group.
* #ManyToOne(targetEntity="CompetenceItem")
* #JoinColumn(name="id_competence_item", referencedColumnName="id_competence_item")
*/
protected $competence_items;
public function __construct()
{
// $this->competence_items = new ArrayCollection();
//delete that line
}
In CompetenceItem class :
class CompetenceItem
{
You need to delete private $competence_groupe; attribute with his annotation :
By this way, when you dump a CompetenceGroupe object you gonna find the competence items.
Also, you can do it with One-To-Many, Bidirectional ,if you want to get the data from the inverse side and from the owning side .
EDIT: If one competenceGroupe can have many competenceItems, then that is a OneToMany relationship; this is the inverse side of the relationship as defined by doctrine, but that is ok. Your question asked how to pull a competenceGroupe and retrieve all related competenceItems. You can do this by making the competenceItems an ArrayCollection in your CompetenceGroupe entity, just as you have done. You do have to define that further in the annotation, see (updated) code below.
For an ArrayCollection, you can remove your method setCompetenceItems and instead define a method addCompetenceItem in your CompetenceGroupe entity.
class CompetenceGroupe
{
/**
* #ORM\OneToMany(targetEntity="CompetenceItem", mappedBy="competence_groupe")
*/
protected $competenceItems;
public function __construct()
{
$this->competenceItems= new ArrayCollection();
}
/**
* Add competenceItem
*
* #param CompetenceItem $competenceItem
* #return CompetenceGroupe
*/
public function addCompetenceItem(CompetenceItem $competenceItem)
{
$this->competence_items->add($competenceItem);
return $this;
}
}
You'll also need to define the owning side to make all this work.
I am new to Doctrine2 and trying to create entities for the following DB structure:
I want to have all machine parts as an array in one attribute of the machine class. I tried this:
class Machine {
....
/**
* #var array
* #ORM\OneToMany(targetEntity="MachineHasPart", mappedBy="machine", cascade={"persist", "remove"}, orphanRemoval=TRUE)
*/
private $parts;
....
public function getParts () {
return array_map(
function ($machineHasPart) {
return $machineHasPart->getPart();
},
$this->parts->toArray()
);
}
}
Where MachineHasPart is a #MappedSuperclass for the intermediate entities/tables (like machineHasCylinder etc), but it failed with:
An exception occurred while executing 'SELECT FROM machineHasPart t0'.
Should I restructure my database to use ORM here? Or there is a solution for my case?
You cannot query a #MappedSuperClass. This is also mentioned in the Doctrine2 documentation in chapter 6.1. Mapped Superclasses:
A mapped superclass cannot be an entity, it is not query-able and persistent
This means you have to either change the target entity to something queryable or you have to make MachineHasPart to a entity and change to single table inheritance.
When I look at your database structure I would suggest changing your Machine entity to have three independent relationships for the parts. One for Belt, one for Cylinder and one for Gear.
Then instead of a generic getParts you will have three methods getBelts, getCylinders and getGears.
If that is really not what you want then you can leave a comment.
UPDATE
You can solve it also with class inheritance. First make a base class Part that is also an entity and use it in the other classes Belt, Cylinder and Gear:
Part:
<?php
namespace Machine\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Part
*
* #ORM\Entity
* #ORM\Table("part")
* #ORM\InheritanceType("SINGLE_TABLE")
* #ORM\DiscriminatorColumn(name="discriminator", type="string")
* #ORM\DiscriminatorMap({
* "part" = "Part",
* "gear" = "Gear",
* "cylinder" = "Cylinder",
* "belt" = "Belt",
* })
* #property int $id
*/
class Part
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var Machine
* #ORM\ManyToOne(targetEntity="Machine\Entity\Machine", inversedBy="parts")
* #ORM\JoinColumn(name="machine_id", referencedColumnName="id", nullable=true)
*/
protected $machine;
/**
* Get id.
*
* #return int
*/
public function getId()
{
return $this->id;
}
/**
* Set id.
*
* #param int $id
* #return self
*/
public function setId($id)
{
$this->id = $id;
return $this;
}
//... add setters and getters for machine as normal ...
}
Extend this class in your other parts:
Belt:
<?php
namespace Machine\Entity;
/**
* Belt
*
* #ORM\Entity
*/
class Belt extends Part
{
}
Cylinder:
<?php
namespace Machine\Entity;
/**
* Cylinder
*
* #ORM\Entity
*/
class Cylinder extends Part
{
}
Gear:
<?php
namespace Machine\Entity;
/**
* Gear
*
* #ORM\Entity
*/
class Gear extends Part
{
}
Now in your machine relate to the parts like as follows.
Machine:
<?php
namespace Machine\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\Collection;
use Doctrine\Common\Collections\ArrayCollection;
/**
* Machine
*
* #ORM\Entity
* #ORM\Table("machine")
* #property int $id
*/
class Machine
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* Get id.
*
* #return int
*/
public function getId()
{
return $this->id;
}
/**
* Set id.
*
* #param int $id
* #return self
*/
public function setId($id)
{
$this->id = $id;
return $this;
}
/**
* #var Collection
* #ORM\OneToMany(targetEntity="Machine\Entity\Part", mappedBy="machine")
*/
protected $parts;
public function __constuct()
{
$parts = new ArrayCollection();
}
/**
*
* #return Collection
*/
public function getParts()
{
return $this->parts;
}
//... add setters and getters for parts as normal ...
}
Extend this class in your other parts:
Reading further in the Doctrine2 documentation in chapter 6.1. Mapped Superclasses (referred to by #Wilt):
... Furthermore Many-To-Many associations are only possible if the mapped superclass is only used in exactly one entity at the moment...
This means in this case the ORM mapping doesn't help. I cannot gather the data of all three entities MachineHasCylinder, MachineHasBelt and MachineHasGear through a MappedSupperclass at the same time.
I think using DQL or Native SQL is the only solution for this problem.
I have a big understanding problem with OneToMany Relationship - i searched a lot but that didnt help, maybe someone can help me with this.
I have a Event Entity with OneToMany Relation
<?php
namespace #\#\#;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Turmforum\BookingBundle\Entity\Contact;
/**
* Event
*
* #ORM\Table(name="events")
* #ORM\Entity
*/
class Event
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\OneToMany(targetEntity="Contact", mappedBy="event")
*/
protected $event_contacts;
/**
*
*/
public function __construct() {
$this->contacts = new ArrayCollection();
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
public function getContacts() {
return $this->contacts;
}
public function addContact(Contact $contact) {
$this->contacts[] = $contact;
return $this;
}
And have a Contact Entity with ManyToOne Relation
<?php
namespace #\#\#;
use Doctrine\ORM\Mapping as ORM;
use Turmforum\BookingBundle\Entity\Event;
/**
* Contact
*
* #ORM\Table(name="contacts")
* #ORM\Entity
*/
class Contact
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\ManyToOne(targetEntity="Event", inversedBy="event_contacts")
* #ORM\JoinColumn(name="event_id", referencedColumnName="id")
*/
protected $event;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* #return mixed
*/
public function getEvent() {
return $this->event;
}
When i try to save my event details over a form i get the error:
Neither the property "event_id" nor one of the methods "getEventId()",
"eventId()", "isEventId()", "hasEventId()", "__get()" exist and have
public access in class "Turmforum\BookingBundle\Entity\Event".
What am i missing?
I'm making entities with Symfony2 and Doctrine2. I made some entities that represent a many-to-many relation between two of my entities.
An example of one of these entities :
/**
* #ORM\Entity
*/
class Contact_Conference_Invitation
{
/**
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Aurae\UserBundle\Entity\Contact")
*/
private $contact;
/**
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Aurae\ConferenceBundle\Entity\Conference")
*/
private $conference;
/**
* #var datetime dateInvitation
*
* #ORM\Column(name="dateInvitation", type="datetime")
*/
private $dateInvitation;
//Getters and setters
}
I have tried updating my sql schema, but the tables corresponding to these entities do not appear. Is there somewhere I have to declare them (config or such)? If not, what's wrong?
Thanks a lot
Edit : I had forgotten the namespace for these class, and that's why they were omitted by Doctrine. Another case closed :) thanks for the answers!
Assumptions ...
No, you don't need to declare them anywhere else than in your Entity directory.
What's the error message you got?
I guess you added
use Doctrine\ORM\Mapping as ORM;
on the top of your classes to let them be mapped.
I tried ...
I tried to generate your entities by adding a simple Contact & Conference entities and it's working fine.
Here are the code snippets:
Contact_Conference_Invitation.php
namespace Ahsio\StackBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
*/
class Contact_Conference_Invitation
{
/**
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Ahsio\StackBundle\Entity\Contact")
*/
private $contact;
/**
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Ahsio\StackBundle\Entity\Conference")
*/
private $conference;
/**
* #var datetime dateInvitation
*
* #ORM\Column(name="dateInvitation", type="datetime")
*/
private $dateInvitation;
//Getters and setters
}
Contact.php
namespace Ahsio\StackBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
*/
class Contact
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #param $id
*/
public function setId($id)
{
$this->id = $id;
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
}
Conference.php
namespace Ahsio\StackBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
*/
class Conference
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #param $id
*/
public function setId($id)
{
$this->id = $id;
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
}
Here are the generated tables:
NB: I used a specific namespace for the entities generation to work fine, you need to change them.
Also don't forget to check that you have automapping enabled.
In your config.yml you should have
doctrine:
orm:
auto_mapping: true
Came across this question because my entities weren't generated as well, this was my issue, it could save some time to people struggling with the same issue.
I don't see the definition of your ManyToMany relation in the sample of code you provided.
As an example, here's a ManyToMany relationship I implemented for a project
Entity Project.php
/**
* #var Provider[]
*
* #ORM\ManyToMany(targetEntity="Provider", mappedBy="projects")
*/
protected $providers = null;
Entity Provider.php
/**
* #var Project[]
*
* #ORM\ManyToMany(targetEntity="Project", inversedBy="providers")
* #ORM\JoinTable(name="PROVIDER_PROJECT")
*/
protected $projects = null;
As you can see, here you define the join table for your ManyToMany relationship.
Of course those entities are specific for my particular project but you get the idea and you can adapt it easily for your needs.
