Getting Started With FOSUserBundle

The Symfony2 security component provides a flexible security framework that allows you to load users from configuration, a database, or anywhere else you can imagine. The FOSUserBundle builds on top of this to make it quick and easy to store users in a database.

So, if you need to persist and fetch the users in your system to and from a database, then you're in the right place.

Installation

Installation is a quick (I promise!) 8 step process:

  1. Download FOSUserBundle
  2. Configure the Autoloader
  3. Enable the Bundle
  4. Create your User class
  5. Configure your application's security.yml
  6. Configure the FOSUserBundle
  7. Import FOSUserBundle routing
  8. Update your database schema

Step 1: Download FOSUserBundle

Ultimately, the FOSUserBundle files should be downloaded to the vendor/bundles/FOS/UserBundle directory.

This can be done in several ways, depending on your preference. The first method is the standard Symfony2 method.

Using the vendors script

Add the following lines in your deps file:

[FOSUserBundle]
    git=git://github.com/FriendsOfSymfony/FOSUserBundle.git
    target=bundles/FOS/UserBundle

Now, run the vendors script to download the bundle:

$ php bin/vendors install

Using submodules

If you prefer instead to use git submodules, the run the following:

$ git submodule add git://github.com/FriendsOfSymfony/FOSUserBundle.git vendor/bundles/FOS/UserBundle
$ git submodule update --init

Step 2: Configure the Autoloader

Add the FOS namespace to your autoloader:

<?php
// app/autoload.php

$loader->registerNamespaces(array(
    // ...
    'FOS' => __DIR__.'/../vendor/bundles',
));

Step 3: Enable the bundle

Finally, enable the bundle in the kernel:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new FOS\UserBundle\FOSUserBundle(),
    );
}

Step 4: Create your User class

The goal of this bundle is to persist some User class to a database (MySql, MongoDB, CouchDB, etc). Your first job, then, is to create the User class for your application. This class can look and act however you want: add any properties or methods you find useful. This is your User class.

This class has just two requirements, which allow it to take advantage of all of the functionality in the FOSUserBundle:

  1. It must extend one of the base User classes from the bundle
  2. It must have an id field

In the following sections, you'll see examples of how your User class should look, depending on how you're storing your users (Doctrine ORM, MongoDB ODM, or CouchDB ODM).

Your User class can live inside any bundle in your application. For example, if you work at "Acme" company, then you might create a bundle called AcmeUserBundle and place your User class in it.

Warning:

If you override the __construct() method in your User class, be sure to call parent::__construct(), as the base User class depends on this to initialize some fields.

a) Doctrine ORM User class

If you're persisting your users via the Doctrine ORM, then your User class should live in the Entity namespace of your bundle and look like this to start:

<?php
// src/Acme/UserBundle/Entity/User.php

namespace Acme\UserBundle\Entity;

use FOS\UserBundle\Entity\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;

    public function __construct()
    {
        parent::__construct();
        // your own logic
    }
}

Note:

User is a reserved keyword in SQL so you cannot use it as table name.

b) MongoDB User class

If you're persisting your users via the Doctrine MongoDB ODM, then your User class should live in the Document namespace of your bundle and look like this to start:

<?php
// src/Acme/UserBundle/Document/User.php

namespace Acme\UserBundle\Document;

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

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

    public function __construct()
    {
        parent::__construct();
        // your own logic
    }
}

c) CouchDB User class

If you're persisting your users via the Doctrine CouchDB ODM, then your User class should live in the Document namespace of your bundle and look like this to start:

<?php
// src/Acme/UserBundle/Document/User.php

namespace Acme\UserBundle\Document;

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

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

    public function __construct()
    {
        parent::__construct();
        // your own logic
    }
}

Step 5: Configure your application's security.yml

In order for Symfony's security component to use the FOSUserBundle, you must tell it to do so in the security.yml file. The security.yml file is where the basic configuration for the security for your application is contained.

Below is a minimal example of the configuration necessary to use the FOSUserBundle in your application:

# app/config/security.yml
security:
    providers:
        fos_userbundle:
            id: fos_user.user_manager

    firewalls:
        main:
            pattern: ^/
            form_login:
                provider: fos_userbundle
            logout:       true
            anonymous:    true

    access_control:
        - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/admin/, role: ROLE_ADMIN }

    role_hierarchy:
        ROLE_ADMIN:       ROLE_USER
        ROLE_SUPER_ADMIN: ROLE_ADMIN

Under the providers section, you are making the bundle's packaged user provider service available via the alias fos_userbundle. The id of the bundle's user provider service is fos_user.user_manager.

Next, take a look at examine the firewalls section. Here we have declared a firewall named main. By specifying form_login, you have told the Symfony2 framework that any time a request is made to this firewall that leads to the user needing to authenticate himself, the user will be redirected to a form where he will be able to enter his credentials. It should come as no surprise then that you have specified the user provider we declared earlier as the provider for the firewall to use as part of the authentication process.

Note:

Although we have used the form login mechanism in this example, the FOSUserBundle user provider is compatible with many other authentication methods as well. Please read the Symfony2 Security component documention for more information on the other types of authentication methods.

The access_control section is where you specify the credentials necessary for users trying to access specific parts of your application. The bundle requires that the login form and all the routes used to create a user and reset the password be available to unauthenticated users but use the same firewall as the pages you want to secure with the bundle. This is why you have specified that the any request matching the /login pattern or starting with /register or /resetting have been made available to anonymous users. You have also specified that any request beginning with /admin will require a user to have the ROLE_ADMIN role.

For more information on configuring the security.yml file please read the Symfony2 security component documentation.

Note:

Pay close attention to the name, main, that we have given to the firewall which the FOSUserBundle is configured in. You will use this in the next step when you configure the FOSUserBundle.

Step 6: Configure the FOSUserBundle

Now that you have properly configured your application's security.yml to work with the FOSUserBundle, the next step is to configure the bundle to work with the specific needs of your application.

Add the following configuration to your config.yml file according to which type of datastore you are using.

# app/config/config.yml
fos_user:
    db_driver: orm # other valid values are 'mongodb', 'couchdb'
    firewall_name: main
    user_class: Acme\UserBundle\Entity\User

Or if you prefer XML:

# app/config/config.xml
<!-- app/config/config.xml -->

<!-- other valid 'db-driver' values are 'mongodb' and 'couchdb' -->
<fos_user:config
    db-driver="orm"
    firewall-name="main"
    user-class="Acme\UserBundle\Entity\User"
/>

Only three configuration values are required to use the bundle:

  • The type of datastore you are using (orm, mongodb, or couchdb).
  • The firewall name which you configured in Step 5.
  • The fully qualified class name (FQCN) of the User class which you created in Step 2

Step 7: Import FOSUserBundle routing files

Now that you have activated and configured the bundle, all that is left to do is import the FOSUserBundle routing files.

By importing the routing files you will have ready made pages for things such as logging in, creating users, etc.

In YAML:

# app/config/routing.yml
fos_user_security:
    resource: "@FOSUserBundle/Resources/config/routing/security.xml"

fos_user_profile:
    resource: "@FOSUserBundle/Resources/config/routing/profile.xml"
    prefix: /profile

fos_user_register:
    resource: "@FOSUserBundle/Resources/config/routing/registration.xml"
    prefix: /register

fos_user_resetting:
    resource: "@FOSUserBundle/Resources/config/routing/resetting.xml"
    prefix: /resetting

fos_user_change_password:
    resource: "@FOSUserBundle/Resources/config/routing/change_password.xml"
    prefix: /change-password

Or if you prefer XML:

<!-- app/config/routing.xml -->
<import resource="@FOSUserBundle/Resources/config/routing/security.xml"/>
<import resource="@FOSUserBundle/Resources/config/routing/profile.xml" prefix="/profile" />
<import resource="@FOSUserBundle/Resources/config/routing/registration.xml" prefix="/register" />
<import resource="@FOSUserBundle/Resources/config/routing/resetting.xml" prefix="/resetting" />
<import resource="@FOSUserBundle/Resources/config/routing/change_password.xml" prefix="/change-password" />

Note:

In order to use the built-in email functionality (confirmation of the account, resetting of the password), you must activate and configure the SwiftmailerBundle.

Step 8: Update your database schema

Now that the bundle is configured, the last thing you need to do is update your database schema because you have added a new entity, the User class which you created in Step 2.

For ORM run the following command.

$ php app/console doctrine:schema:update --force

For MongoDB users you can run the following command to create the indexes.

$ php app/console doctrine:mongodb:schema:create --index

You now can login at http://app.com/app_dev.php/login!

Next Steps

Now that you have completed the basic installation and configuration of the FOSUserBundle, you are ready to learn about more advanced features and usages of the bundle.
