I have two class, User and PersonalData. We need relation OnetoOne with Doctrine in Symfony2. In my code I tried this relations, but in MySQL doesnt appear the foreign key.
My code:
namespace TFC\UserBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* User
*/
/** #ORM\Entity */
class User
{
/**
* #Id #Column(type="integer") #GeneratedValue
*/
private $id;
/**
* #var string
*/
private $email;
}
use Doctrine\ORM\Mapping as ORM;
/**
* PersonalData
*/
/** #ORM\Entity */
class PersonalData
{
/** #Id #OneToOne(targetEntity="User") */
private $userId;
/**
* #var string
*/
private $firstName;
}
You have to prefix with #ORM all your annotations like this:
#ORM\Id
#ORM\Column(type="integer")
#ORM\GeneratedValue(strategy="AUTO")
This "Unidirectional association" needs to be placed on User entity (because I think you want to load that informations from the User object...) and you don't need to care about the foreign key because doctrine create it automatically.
So place a $personalData property on User Entity and apply there the association, then delete $userId from PersonalData and add the $id property like did in User.
Even if the documentation claims that is not necessary have you tried something like:
#JoinColumn(name="userId", referencedColumnName="id")
When you generate the entity do you get any message?

I have many ads entities (MotorAds, RealestateAds, ElectronicsAds, ...) that share some attributes like title and description. In order to avoid redefining these attributes for each Ads entity, one can use the mapped superclass methods as follows:
<?php
/** #MappedSuperclass */
class MappedSuperclassAds{
/**
* #var string
*
* #ORM\Column(name="title", type="string", length=255, nullable=false)
*/
private $title;
/**
* #var string
*
* #ORM\Column(name="description", type="text", nullable=false)
*/
private $description;
}
Then, the inheritance will do the job.
Now, what is the problem? The problem is that each Ads entity is related to its entity that defines the list of users that added the ads to their favorites. To do that (the MotorsAds entity for example),
1.linking the MotorsAds entity to its MotorsFavorite entity through that code:
/**
* #ORM\OneToMany(targetEntity="Minn\AdsBundle\Entity\MotorsFavorite",
* mappedBy="motors",cascade={"persist", "remove"})
* #ORM\JoinColumn(nullable=true)
*/
private $favorites;
2.Defining the MotorsFavorite entity as fellows:
<?php
namespace Minn\AdsBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* MotorsFavorite
*
* #ORM\Table(
* uniqueConstraints={#ORM\UniqueConstraint(name="unique_fav_motors",
* columns={"user_id", "motors_id"})})
* #ORM\Entity(repositoryClass="Minn\AdsBundle\Entity\MotorsFavoriteRepository")
* #ORM\HasLifecycleCallbacks()
*/
class MotorsFavorite {
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\ManyToOne(targetEntity="Minn\UserBundle\Entity\User")
* #ORM\JoinColumn(nullable=false)
*/
private $user;
/**
* #ORM\ManyToOne(targetEntity="Minn\AdsBundle\Entity\MotorsAds", inversedBy="favorites")
* #ORM\JoinColumn(nullable=false, onDelete="CASCADE")
*/
private $motors;
//...
}
As you can see, the linkage between the MotorAds and MotorFavorite is a hard linkage, which means that I have to create a Favorite entity for each Ads entity I create (FavoriteMotors, FavoriteRealestate, FavoriteElectronics, ...). This is a long and repetitive work.
So my question is:
1.Creating a super mapped class called SuperMappedFavorite which will only include the $id and $user attributes will reduce the repetitive work. But what about the the attribute $motors? $motors is hardly linked to the entity MotorsAds as you see here:#ORM\ManyToOne(targetEntity="Minn\AdsBundle\Entity\MotorsAds", inversedBy="favorites"). All the burden of the work is in the setters and getters of $motors.
2.Is it possible to make the target entity an interface like this:
<?php
// SuperMappedFavorite.php
// ...
#ORM\ManyToOne(targetEntity="Minn\AdsBundle\Favorite\FavoriteAwareInterface", inversedBy="favorites")
private $object;
// ...
and the MotorsAds entity will be implementing in this the FavoriteAwareInterface
If anyone has a good link/article regarding this kind of issue, I will be happy to have it.
Thanks.
Yes, you can set an interface as target entity, as described in the Symfony documentation.
The process is basically:
defining the interface (your Minn\AdsBundle\Favorite\FavoriteAwareInterface),
setting the interface in the parent entity (as you already did),
implementing the interface in a different entity (would be class MotorsFavorite implements FavoriteAwareInterface) – and yes, it can also be derived from a mapped superclass,
and then telling Doctrine to use your implementation through the doctrine.orm.resolve_target_entities config parameter.
See the documentation for details and a code example.
I have two roles in my application, for example ROLE_USER and ROLE_SUPERUSER. Users are stored in the database using Doctrine. Users with the ROLE_USER role are based on a simple User class. (Getters and setters have been removed for readability.)
Acme\MyBundle\Entity\User.php
namespace Acme\MyBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
/**
* #ORM\Entity
* #ORM\Entity(repositoryClass="Acme\MyBundle\Entity\UserRepository")
* #ORM\Table("users")
* #UniqueEntity(
* fields={"email"},
* message="email already used"
* )
*/
class User implements UserInterface, \Serializable
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="string", length=255, unique=true)
* #Assert\NotBlank()
* #Assert\Email()
*/
protected $email;
/**
* #ORM\Column(type="string", length=32)
*/
private $salt;
/**
* #ORM\Column(type="string", length=4096)
*/
private $password;
/**
* #ORM\Column(name="is_active", type="boolean")
*/
private $isActive;
public function __construct()
{
$this->isActive = true;
$this->salt = md5(uniqid(null, true));
}
/**
* #inheritDoc
*/
public function getRoles()
{
return array('ROLE_USER','ROLE_SUPERUSER');
}
}
I have a SuperUser class that extends User to provides more fields that only users with ROLE_SUPERUSER would need.
Acme\MyBundle\Entity\SuperUser.php
namespace Acme\MyBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity
* #ORM\Table(name="super_users")
*/
class SuperUser extends User
{
/**
* #var integer
*/
protected $id;
/**
* #var string
*/
protected $email;
/**
* #ORM\Column(type="string", length=32)
*/
proteced $avatar;
/**
* #ORM\Column(type="string", length=50, unique=true)
*/
proteced $username;
}
In my controllers I'm using $user = $this -> getUser(); to get the current user, but this returns an instance of the User class and I cannot access the SuperUser properties or methods, even if the user has the role ROLE_SUPERUSER.
For example, I would like to be able to use the following code.
if ($this->get('security.context')->isGranted('ROLE_SUPERUSER')) {
$avatar = $this->getUser()-> avatar;
}
Is there anyway to be able to do that? I would say there's something to do with Doctrine relationships, but I don't really know what to change.
By the way, as you can see I don't have an username field in my standard User class, it's only present in SuperUser. Does this may cause any problems since the authentication is based on username?
I think my problem hasn't been clearly exposed, but this might be due to my current code, which is wrong.
I don't have two user tables. I want only one User class (with one users table). The authentication is operated only on this class with email and password.
I have another class SuperUser```that provides extra fields to users that have the ROLE_SUPERUSER`` role, but the superusers are users and have an entry in the users table. I just want to create a left join on the concerned rows, that's why I used inheritance. (Maybe there's a better way to do it.)
If I want to get all the emails, I can query the users table. If I want to get all the usernames, since only superusers have one, I can query the superusers table.
I would go for two entities with a OneToOne relationship (No extends)
/** #Entity **/
class SuperUser
{
// ...
/**
* #ORM\OneToOne(targetEntity="User", mappedBy="superUser")
**/
private $user;
// ...
}
/** #Entity **/
class User
{
// ...
/**
* #ORM\OneToOne(targetEntity="SuperUser", inversedBy="user")
* #ORM\JoinColumn(name="user_id", referencedColumnName="id")
**/
private $superUser;
// ...
}
Otherwise take a look at Inheritance Mapping
You should have two user providers then, and use one master provider:
security:
providers:
master_provider:
chain:
providers: [user, super_user]
user:
entity: { class: Acme\MyBundle\Entity\User, property: username }
super_user:
entity: { class: Acme\MyBundle\Entity\SuperUser, property: username }
firewalls:
main:
provider: master_provider
http://symfony.com/doc/current/cookbook/security/multiple_user_providers.html
My problem is quite simple but i search for an hour without succeed, i would like to add some constraint to the UserEntity. For example, i would like to limit the length of a username
I think the best way is to not touche FOS in Vendor. I have create my own userBundle with my own layout.html etc ... But i cannot override attribut who is already existing in FosuserBundle (it's working for the layout overriding btw my userBundle is a child of FOS)
the funny thing is "id" has no problem for the overriding
My User entity :
<?php
namespace Diane\UserBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
/**
* User
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="Diane\UserBundle\Entity\UserRepository")
*/
class User extends BaseUser
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var string
* #ORM\Column(name="username", type="string", length=10)
*/
protected $username;
}
Fos User model :
<?php
namespace FOS\UserBundle\Model;
use Doctrine\Common\Collections\Collection;
use Doctrine\Common\Collections\ArrayCollection;
abstract class User implements UserInterface, GroupableInterface
{
protected $id;
/**
* #var string
*/
protected $username;
...
}
i have already try to remove :
/**
* #var string
*/
Error message :
Doctrine\ORM\Mapping\MappingException] Duplicate definition of column
'username' on entity 'Diane\UserBundle\Entity\User' in a field or
discriminator column mapping.
Thanks for any idea you could give me
Try AttributeOverrides Doctrine annotation:
/**
* User
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="Diane\UserBundle\Entity\UserRepository") / class User extends
*
* #ORM\AttributeOverrides({
* #ORM\AttributeOverride(name="username",
* column=#ORM\Column(
* name = "username",
* type = "string",
* length = 10
* )
* )
* })
*
*/
class User extends BaseUser
{
I have installed the FOS UserBundle.
The problem is: the "id" field of my User-Table is called userID.
I can't change it bc of other Tables and Programming that is dependent on the userID field.
If i try to login, i get an error:
Unrecognized field: id
The problem seems to lie in the call for the id field:
UserManager ->findUserBy (array('id' => 1))
Can I somehow override FOS UserBundle so that the findby() method transfers id to userID?
Or do i get it totally wrong and have to do it another way?
Field names in the entity don't have to be identical to the field names in your sql table. So you can use "id" as field in your doctrine entity and map it to a "userID" field in your sql table.
If you are using Doctrine annotations for your user entity like in the FOSUserBundle documentation, this could do the trick:
/**
* #ORM\Id
* #ORM\Column(name="userID", type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
I haven't tested it and there is a chance that it doesn't work, because the id field is always a bit "special", but it may be worth a try.
Generate your own UseBundle and add in define the entity something like this.
<?php
namespace Demo\UserBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
/**
* #ORM\Entity(repositoryClass="Sciviz\UserBundle\Entity\UserRepository")
* #ORM\Table(name="fos_user")
*/
class User extends BaseUser {
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/** #ORM\Column(name="first_name", type="string", length=255, nullable=true) */
protected $first_name;
..................
Also see this tutorial
http://knpuniversity.com/screencast/fosuserbundle-ftw
your column name "USER_ID" can be case sensitive.
/**
* #ORM\Entity
* #ORM\Table(name="user-table")
*/
class User extends BaseUser
{
/**
* #ORM\Id
* #ORM\Column(type="integer", name="USER_ID")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
}
i have an already created symfony bundle. i wanted to add another bundle for my application separately. so now im facing a problem that how to extend an entity from old bundle to newly created one. i extended it normally but it giving errors.
i have these 2 bundles,
MyFirstBundle
MySecondBundle
MyFirstBundle entity,
namespace My\FirstBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
*
* #ORM\Table(name="companies")
* #ORM\Entity
* #ORM\HasLifecycleCallbacks
*/
class Company
{
/**
* #var integer $id
*
* #ORM\Column(name="id", type="integer", nullable=false)
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*
* #Groups({"list_companies", "company_details", "ad_details"})
*/
private $id;
/**
* #ORM\Column(name="name", type="string", length=50, nullable=true)'
*
* #Groups({"ad_details"})
*/
private $name;
MySecondBundle Entity,
namespace My\SecondBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use My\FirstBundle\Entity\Company as BaseCompany;
class Companies extends BaseCompany
{
public function __construct() {
parent::__construct();
}
}
im not sure that i can extend my entity like this. im getting error when creating forms with this entity
Class "MySecondBundle:companies" seems not to be a managed Doctrine entity. Did you forget to map it?
You need to add the doctrine annotations for the second entity as well.
/**
*
* #ORM\Table(name="companies")
* #ORM\Entity
* #ORM\HasLifecycleCallbacks
*/
class Companies extends BaseCompany
{
public function __construct() {
parent::__construct();
}
}
