Using Groups With FOSUserBundle

FOSUserBundle allows you to associate groups to your users. Groups are a way to group a collection of roles. The roles of a group will be granted to all users belonging to it.

Note:

Symfony2 supports role inheritance so inheriting roles from groups is not always needed. If the role inheritance is enough for your use case, it is better to use it instead of groups as it is more efficient (loading the groups triggers the database).

To use the groups, you need to explicitly enable this functionality in your configuration. The only mandatory configuration is the fully qualified class name (FQCN) of your Group class which must implement FOS\UserBundle\Model\GroupInterface.

Below is an example configuration for enabling groups support.

In YAML:

# app/config/config.yml
fos_user:
    db_driver: orm
    firewall_name: main
    user_class: Acme\UserBundle\Entity\User
    group:
        group_class: Acme\UserBundle\Entity\Group

Or if you prefer XML:

# app/config/config.xml
<fos_user:config
    db-driver="orm"
    firewall-name="main"
    user-class="Acme\UserBundle\Entity\User"
>
    <fos_user:group group-class="Acme\UserBundle\Entity\Group" />
</fos_user:config>

The Group class

The simplest way to create a Group class is to extend the mapped superclass provided by the bundle.

a) ORM Group class implementation

Annotations
// src/MyProject/MyBundle/Entity/Group.php
<?php

namespace MyProject\MyBundle\Entity;

use FOS\UserBundle\Model\Group as BaseGroup;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="fos_group")
 */
class Group extends BaseGroup
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
     protected $id;
}

Note: Group is a reserved keyword in SQL so it cannot be used as the table name.

yaml
<?php
// src/Acme/UserBundle/Entity/Group.php

namespace Acme\UserBundle\Entity;

use FOS\UserBundle\Model\Group as BaseGroup;

/**
 * Group
 */
class Group extends BaseGroup
{
}
# src/Acme/UserBundle/Resources/config/doctrine/Group.orm.yml
Acme\UserBundle\Entity\Group:
    type:  entity
    table: fos_group
    id:
        id:
            type: integer
            generator:
                strategy: AUTO

b) MongoDB Group class implementation

// src/MyProject/MyBundle/Document/Group.php
<?php

namespace MyProject\MyBundle\Document;

use FOS\UserBundle\Model\Group as BaseGroup;
use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;

/**
 * @MongoDB\Document
 */
class Group extends BaseGroup
{
    /**
     * @MongoDB\Id(strategy="auto")
     */
    protected $id;
}

c) CouchDB Group class implementation

// src/MyProject/MyBundle/Document/Group.php
<?php

namespace MyProject\MyBundle\Document;

use FOS\UserBundle\Model\Group as BaseGroup;
use Doctrine\ODM\CouchDB\Mapping as CouchDB;

/**
 * @CouchDB\Document
 */
class Group extends BaseGroup
{
    /**
     * @CouchDB\Id
     */
    protected $id;
}

Defining the User-Group relation

The next step is to map the relation in your User class.

a) ORM User-Group mapping

Annotations
// src/MyProject/MyBundle/Entity/User.php
<?php

namespace MyProject\MyBundle\Entity;

use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="fos_user")
 */
class User extends BaseUser
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\ManyToMany(targetEntity="MyProject\MyBundle\Entity\Group")
     * @ORM\JoinTable(name="fos_user_user_group",
     *      joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")},
     *      inverseJoinColumns={@ORM\JoinColumn(name="group_id", referencedColumnName="id")}
     * )
     */
    protected $groups;
}
yaml
<?php
// src/Acme/UserBundle/Entity/User.php

namespace Acme\UserBundle\Entity;

use FOS\UserBundle\Model\User as BaseUser;

/**
 * User
 */
class User extends BaseUser
{
    public function __construct()
    {
        parent::__construct();
        // your own logic
    }
}
# src/Acme/UserBundle/Resources/config/doctrine/User.orm.yml
Acme\UserBundle\Entity\User:
    type:  entity
    table: fos_user
    id:
        id:
            type: integer
            generator:
                strategy: AUTO
    manyToMany:
        groups:
            targetEntity: Group
            joinTable:
                name: fos_user_group
                joinColumns:
                    user_id:
                        referencedColumnName: id
                inverseJoinColumns:
                    group_id:
                        referencedColumnName: id
<?xml version="1.0" encoding="UTF-8"?>

            <generator strategy="AUTO" />

                    <join-column name="user_id" referenced-column-name="id"/>
                </join-columns>                  
                <inverse-join-columns>
                    <join-column name="group_id" referenced-column-name="id" />                 
                </inverse-join-columns>                               
            </join-table>
        </many-to-many>
    </entity>
</doctrine-mapping>   

b) MongoDB User-Group mapping

// src/MyProject/MyBundle/Document/User.php
<?php

namespace MyProject\MyBundle\Document;

use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;

/**
 * @MongoDB\Document
 */
class User extends BaseUser
{
    /** @MongoDB\Id(strategy="auto") */
    protected $id;

    /**
     * @MongoDB\ReferenceMany(targetDocument="MyProject\MyBundle\Document\Group")
     */
    protected $groups;
}

c) CouchDB User-Group mapping

// src/MyProject/MyBundle/Document/User.php
<?php

namespace MyProject\MyBundle\Document;

use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ODM\CouchDB\Mapping as CouchDB;

/**
 * @CouchDB\Document
 */
class User extends BaseUser
{
    /**
     * @CouchDB\Id
     */
    protected $id;

    /**
     * @CouchDB\ReferenceMany(targetDocument="MyProject\MyBundle\Document\Group")
     */
    protected $groups;
}

Enabling the routing for the GroupController

You can import the routing file group.xml to use the built-in controller to manipulate groups.

In YAML:

# app/config/routing.yml
fos_user_group:
    resource: "@FOSUserBundle/Resources/config/routing/group.xml"
    prefix: /group
