I would like to create a slug with the combinations of relations of external tables. I would like to take 2 values from a table and another value from un'atra table. I tried to do this but I do not understand how to add two values and another table .. and it is required to have the fields (in my case empty)?
/**
* #ORM\OneToOne(targetEntity="Acme\UserBundle\Entity\User", inversedBy="profile")
* #ORM\JoinColumn(name="user_id", referencedColumnName="id")
* */
private $utente;
/**
* #Gedmo\Slug(handlers={
* #Gedmo\SlugHandler(class="Gedmo\Sluggable\Handler\RelativeSlugHandler", options={
* #Gedmo\SlugHandlerOption(name="relationField", value="utente"),
* #Gedmo\SlugHandlerOption(name="relationSlugField", value="nickname"),
* #Gedmo\SlugHandlerOption(name="separator", value="-")
* })
* }, separator="-", updatable=true, fields={"empty"})
* #ORM\Column(length=64, unique=true)
*/
private $slug;
I would also email as well as username field,and add another relationField

I want to make a ManyToMany relation in Doctrine with Symfony 2 between a group and an user : many users can be in many groups and many groups can have many users.
Then in my entities, i do this :
Groupe.php
/**
* Many Groups have Many clients.
* #ORM\ManyToMany(targetEntity="Utilisateurs\UtilisateursBundle\Entity\Client", mappedBy="groupe")
* #ORM\JoinTable(name="client_groupe")
*/
private $clients;
/**
* Get clients
*
* #return \Doctrine\Common\Collections\Collection
*/
public function getClients()
{
return $this->clients;
}
Client.php
/**
* #ORM\ManyToMany(targetEntity="Ecommerce\EcommerceBundle\Entity\Groupe", inversedBy="clients")
* #ORM\JoinTable(name="client_groupe",
* joinColumns={#ORM\JoinColumn(name="client_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="groupe_id", referencedColumnName="id")}
* )
*/
private $groupe;
but when I call the getClients() function on my entity $groupe, following error occured :
FROM client t0 WHERE client_groupe.groupe_id = ?' with params ["2"]:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'client_groupe.groupe_id' in 'where clause'
It doesn't add the client_groupe table in the from clause.
Someone can help me ?
No need to add client_groupe table in from clause. Try after removing * #ORM\JoinTable(name="client_groupe") from Groupe.php. Have a look at following working example of ManyToMany relationship scenario.
Groupe.php
/**
* Many Groups have Many clients
* #ORM\ManyToMany(targetEntity="Utilisateurs\UtilisateursBundle\Entity\Client", mappedBy="groupe")
*/
private $clients;
Client.php
/**
* #ORM\ManyToMany(targetEntity="Ecommerce\EcommerceBundle\Entity\Groupe", inversedBy="clients")
* #ORM\JoinTable(name="client_groupe",
* joinColumns={#ORM\JoinColumn(name="client_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="groupe_id", referencedColumnName="id")}
* )
*/
private $groupe;
client_id and groupe_id is fields of client_groupe table. Generate Getter and setter using doctrine command and update database using bin/console doctrine:schema:update --force command.
I would like to make uniqueConstraint user and lesson.
/**
* #ORM\Table(name="ReviewSchool",uniqueConstraints={
* #ORM\UniqueConstraint(name="lessonid", columns={"lesson", "user"})})
* #ORM\Entity
* #ORM\HasLifecycleCallbacks
*/
class ReviewSchool
{
* #ORM\ManyToOne(targetEntity="Lesson",inversedBy="reviewschool")
* #ORM\JoinColumn(name="review_lesson", referencedColumnName="id",onDelete="cascade")
*/
private $lesson;
/**
*
* #ORM\ManyToOne(targetEntity="User",inversedBy="reviewschool")
* #ORM\JoinColumn(name="review_user",referencedColumnName="id",onDelete="cascade")
*/
private $user;
However it shows
[Doctrine\DBAL\Schema\SchemaException]
There is no column with name 'lesson' on table 'ReviewSchool'.
Surely I have 'lesson' column, how can I solve this?
I have misunderstood something??
It allows to hint the SchemaTool to generate a database unique constraint on the specified table columns. It only has meaning in the SchemaTool schema generation context.
So you have to use column names. In your case:
#ORM\UniqueConstraint(columns={"review_lesson", "review_user"})}
I'm pulling a lot of data to cache locally, the data i pull is in json format and has along with it Unique Id's for each record.
Is there a way i can tell doctrine to use this as the id for the table?
I'm only going to be populating these tables with data from my json, i wont be adding any new records from other sources only from my json pull.
is it possible to get doctrine to use a field from my json pull as the primary key?.
when i use doctrine:generate:entity
it automatically adds an id field I would ideally like to get rid of this and use the uniqueID column from my data pull. ($teamKey)
say for example this is my entity
/**
* Team
*
* #ORM\Table("fp_team)
* #ORM\Entity(repositoryClass="FantasyPro\DataBundle\Entity\TeamRepository")
*/
class Team
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="teamKey", type="string", length=50, nullable=false)
*/
private $teamKey;
/**
more properties ...........
*/
is it just a case of deleting the existing $id property and modifying my $teamKey property to:
/**
* #var string
* #ORM\Id
* #ORM\Column(name="teamKey", type="string", length=50, unique=true, nullable=false)
*/
private $teamKey;
Is it more complex than that or not possible?
does the unique id field for doctrine have to be called $id ?
Theoretically, it depends on your DB. But, generally speaking, any DB type should let you set any ID you want.
So, you can always do $entity->setId() any time you want, and persist it with that ID, with no problem.
I having a following issue, I need to make a relationship with two tables, but with no regular id, i need to use strings column. Something like this:
/**
* #ORM\Entity
* #ORM\Table(name="sigtap_tb_procedimento")
*/
class Procedimento
{
/**
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* #ORM\OneToMany(targetEntity="ExcecaoCompatibilidade", mappedBy="procedimento_restricao")
* #ORM\JoinColumn(name="co_procedimento_restricao", referencedColumnName="co_procedimento")
*/
private $restricoes;
}
And another Entity
/**
* #ORM\Entity
* #ORM\Table(name="sigtap_rl_excecao_compatibilidade")
*/
class ExcecaoCompatibilidade
{
/**
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* #ORM\ManyToOne(targetEntity="Procedimento", inversedBy="restricoes")
* #ORM\JoinColumn(name="co_procedimento_restricao", referencedColumnName="co_procedimento")
*/
private $procedimento_restricao;
}
co_procedimento_restricao and co_procedimento_restricao are string type, The relation does not working. How can i solve this issue?
Your relation needs to reference a primary key in the other table.
May be I misunderstood your question but cant you reference the id collumn the relationship like this:
/**
* #ORM\OneToMany(targetEntity="ExcecaoCompatibilidade", mappedBy="procedimento_restricao")
*/
private $restricoes;
/**
* #ORM\ManyToOne(targetEntity="Procedimento", inversedBy="restricoes")
* #ORM\JoinColumn(name="co_procedimento_restricao", referencedColumnName="id")
*/
private $procedimento_restricao;
Take a look here:
http://docs.doctrine-project.org/en/2.0.x/reference/association-mapping.html
using one-to-many relations with doctrine
The side using #OneToMany is always the inverse side of a relation from doctrine's pov ( possibly not what you consider being the inverse side ) and never has a join-column definition.
Remove the #JoinColumn annotation from class Procedimento.
#OneToMany has to use mappedBy and #ManyToOne (the owning side) uses inversedBy.
The join-column (or join-table) definition has to be on the owning side together with #ManyToOne.
When using a join-column the name of this column (which will be added to the table of the owning side entity aka the side being "many") will be specified by name="column_name" and the referenced foreign key to store in there is the referencedColumnName="id"definition of the #JoinColum annotation.
I have a problem with serializing entity with many relations using groups.
I have a problem with serializing related entities this way.
Let's say I have two entities: Product and related Element.
/**
*
* #Serializer\ExclusionPolicy("none")
*/
class Product {
/**
* Primary key
* #var integer $id
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*
* #Serializer\Groups({"list","details"})
* #Serializer\Type("integer")
*/
protected $id;
/**
* #Serializer\Groups({"list","details"})
* #Serializer\Type("string")
*/
protected $name;
/**
* #ORM\Column(name="description", type="string", length=4096, nullable=true)
*
* #Serializer\Groups({"details"})
* #Serializer\Type("string")
*/
protected $description;
/**
* #var ArrayCollection
*
* #ORM\OneToMany(targetEntity="Madden\ProjectBundle\Entity\ProjectResource", mappedBy="project")
* #Serializer\Groups({"details"})
* #Serializer\Type("ArrayCollection<Element>")
*/
protected $details1;
/**
* Relation to project tasks
* #ORM\OneToMany(targetEntity="Madden\ProjectBundle\Entity\ProjectTask", mappedBy="project")
* #Serializer\Exclude()
* #Serializer\Type("ArrayCollection<Element>")
*/
protected $details2;
...
}
Element entity has a similar structure:
/**
*
* #Serializer\ExclusionPolicy("none")
*/
class Element {
/**
* Primary key
* #var integer $id
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*
* #Serializer\Groups({"list","details"})
* #Serializer\Type("integer")
*/
protected $id;
/**
* #Serializer\Groups({"list","details"})
* #Serializer\Type("string")
*/
protected $name;
/**
* #ORM\Column(name="description", type="string", length=4096, nullable=true)
*
* #Serializer\Groups({"details"})
* #Serializer\Type("string")
*/
protected $description;
...
}
My problem is that when I'm serializing Product with 'details' group entity I want to serialize only id's of Elements but as you see entity has defined same groups as Product (in case that I would need details of element object) because I want have unified groups on all my entities and prevent making hundreds of groups like 'product_details','element_details', and so on.
Is there a way to eventualy change serialization group when I visit relation or something like that? Handler maybe or something like that?
Regards and thanks for any help
Unfortunately, you can't really (but keep reading ;-)), well at least not without changes to the serializer library. The culprit is that the list of groups is fixed within a GroupExclusionStrategy (which is referenced by the Context) the minute you start the serialization process. There is actually an assertion within the code that prevents modification of the exclusion strategy once the (de-)serialization is running.
But as it happens, I had the exact same problem in a project of mine as well, and I hacked the necessary changes into the serializer code. I have cleaned the code up a bit and uploaded it to Github (https://github.com/andreasferber/serializer/tree/recursion-groups).
It adds new property metadata with which you can add, remove or override the groups when descending into subobjects. With annotations it looks like this:
/**
* #Serializer\RecursionGroups(set={"foo", "bar"}, add={"baz"}, remove={"Default"})
*/
private $myProperty;
You should be able to use XML or Yaml metadata as well, however this is untested since I don't use them and I haven't added test cases yet. Have a look at the reference documentation. Since I haven't done any optimizations yet either, if your entities are really large and deeply nested, it might have a noticable performance impact.
Please let me know if you find this useful, or if you have any suggestions, because if this isn't only needed by me, I will add some tests and try to submit it upstream.
A solution for this is actually described in the official documentation.
That being said the solution proposed by #aferber seems better on many points: easier to maintain, less verbose, more flexible...
You need to use setGroups.
The _group suffix used in the official documentation is not needed.
$context->setGroups([
'Default', //if you want
// use this linked entity but show only its id
'group_of_linked_field',
'group_of_linked_field' => [
'id' // you will need to define this group first
],
// use this linked entity and show fields as described
'group_of_other_linked_field',
'group_of_other_linked_field' => [
// just as an example
'Default',
'details',
],
]);
This does not work with addGroup or addGroups! Both of them won't accept associative arrays. setGroups is your (only?) solution.
