PropelBundle

This is the official implementation of Propel in Symfony2.

Currently supports:

  • Generation of model classes based on an XML schema (not YAML) placed under BundleName/Resources/*schema.xml.
  • Insertion of SQL statements.
  • Runtime autoloading of Propel and generated classes.
  • Propel runtime initialization through the XML configuration.
  • Migrations Propel 1.6.
  • Reverse engineering from existing database.
  • Integration to the Symfony2 Profiler.
  • Load SQL, YAML and XML fixtures.
  • Create/Drop databases.
  • Integration with the Form component.
  • Integration with the Security component.
  • Propel ParamConverter can be used with Sensio Framework Extra Bundle.

Installation

public function registerBundles()
{
    $bundles = array(
        ...

        // PropelBundle
        new Propel\PropelBundle\PropelBundle(),
        // register your bundles
        new Sensio\HelloBundle\HelloBundle(),
    );

    ...
}
  • Don't forget to register the PropelBundle namespace in app/autoload.php:
$loader->registerNamespaces(array(
    ...

    'Propel' => __DIR__.'/../vendor/bundles',
));

Sample Configuration

Project configuration

# in app/config/config.yml
propel:
    path:       "%kernel.root_dir%/../vendor/propel"
    phing_path: "%kernel.root_dir%/../vendor/phing"
#    logging:   %kernel.debug%
#    build_properties:
#        xxxxx.xxxxx: xxxxxx
#        xxxxx.xxxxx: xxxxxx

# in app/config/config*.yml
propel:
    dbal:
        driver:               mysql
        user:                 root
        password:             null
        dsn:                  mysql:host=localhost;dbname=test;charset=UTF8
        options:              {}
        attributes:           {}
#        default_connection:       default
#        connections:
#           default:
#               driver:             mysql
#               user:               root
#               password:           null
#               dsn:                mysql:host=localhost;dbname=test
#               options:
#                   ATTR_PERSISTENT: false
#               attributes:
#                   ATTR_EMULATE_PREPARES: true
#               settings:
#                   charset:        { value: UTF8 }
#                   queries:        { query: 'INSERT INTO BAR ('hey', 'there')' }

options, attributes and settings are parts of the runtime configuration. See Runtime Configuration File documentation for more explanation.

Build properties

You can define build properties by creating a propel.ini file in app/config and put build properties (see Build properties Reference).

# in app/config/propel.ini
xxxx.xxxx.xxxx = XXXX

But you can follow the Symfony2 way by adding build properties in app/config/config.yml:

# in app/config/config.yml
propel:
    build_properties:
        xxxxx.xxxx.xxxxx:   XXXX
        xxxxx.xxxx.xxxxx:   XXXX
        ...

Sample Schema

Place the following schema in src/Sensio/HelloBundle/Resources/config/schema.xml :

<?xml version="1.0" encoding="UTF-8"?>
<database name="default" namespace="Sensio\HelloBundle\Model" defaultIdMethod="native">

    <table name="book">
        <column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true" />
        <column name="title" type="varchar" primaryString="1" size="100" />
        <column name="ISBN" type="varchar" size="20" />
        <column name="author_id" type="integer" />
        <foreign-key foreignTable="author">
            <reference local="author_id" foreign="id" />
        </foreign-key>
    </table>

    <table name="author">
        <column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true" />
        <column name="first_name" type="varchar" size="100" />
        <column name="last_name" type="varchar" size="100" />
    </table>

</database>

Commands

Build Process

Call the application console with the propel:build command:

> php app/console propel:build [--classes] [--sql] [--insert-sql]

Insert SQL

Call the application console with the propel:insert-sql command:

> php app/console propel:insert-sql [--force]

Note that the --force option is needed to actually execute the SQL statements.

Use The Model Classes

Use the Model classes as any other class in Symfony2. Just use the correct namespace, and Symfony2 will autoload them:

class HelloController extends Controller
{
    public function indexAction($name)
    {
        $author = new \Sensio\HelloBundle\Model\Author();
        $author->setFirstName($name);
        $author->save();

        return $this->render('HelloBundle:Hello:index.html.twig', array('name' => $name, 'author' => $author));
    }
}

Migrations

Generates SQL diff between the XML schemas and the current database structure:

> php app/console propel:migration:generate-diff

Executes the migrations:

> php app/console propel:migration:migrate

Executes the next migration up:

> php app/console propel:migration:migrate --up

Executes the previous migration down:

> php app/console propel:migration:migrate --down

Lists the migrations yet to be executed:

> php app/console propel:migration:status

Working with existing databases

Run the following command to generate an XML schema from your default database:

> php app/console propel:reverse

You can define which connection to use:

> php app/console propel:reverse --connection=default

Fixtures

You can load your own fixtures by using the following command:

> php app/console propel:fixtures:load [-d|--dir[="..."]] [--xml] [--sql] [--yml] [--connection[="..."]]

As usual, --connection allows to specify a connection.

The --dir option allows to specify a directory containing the fixtures (default is: app/propel/fixtures/). Note that the --dir expects a relative path from the root dir (which is app/).

The --xml parameter allows you to load only XML fixtures. The --sql parameter allows you to load only SQL fixtures. The --yml parameter allows you to load only YAML fixtures.

You can mix --xml, --yml and --sql parameters to load XML, YAML and SQL fixtures. If none of this parameter are set all files YAML, XML and SQL in the directory will be load.

A valid XML fixtures file is:

<Fixtures>
    <Object Namespace="Awesome">
        <o1 Title="My title" MyFoo="bar" />
    </Object>
    <Related Namespace="Awesome">
        <r1 ObjectId="o1" Description="Hello world !" />
    </Related>
</Fixtures>

A valid YAML fixtures file is:

\Awesome\Object:
     o1:
         Title: My title
         MyFoo: bar

 \Awesome\Related:
     r1:
         ObjectId: o1
         Description: Hello world !

You can dump data into YAML fixtures file by using this command:

> php app/console propel:fixtures:dump [--connection[="..."]]

Dumped files will be written in the fixtures directory: app/propel/fixtures/ with the following name: fixtures_99999.yml where 99999 is a timestamp. Once done, you will be able to load this files by using the propel:fixtures:load command.

Graphviz

You can generate Graphviz file for your project by using the following command line:

> php app/console propel:graphviz

It will write files in app/propel/graph/.

Database

You can create a database:

> php app/console propel:database:create [--connection[=""]]

As usual, --connection allows to specify a connection.

You can drop a database:

> php app/console propel:database:drop [--connection[=""]] [--force]

As usual, --connection allows to specify a connection.

Note that the --force option is needed to actually execute the SQL statements.

Table

You can drop one or several table:

> php app/console propel:table:drop [--force] [--connection[="..."]] [table1] ... [tableN]

As usual, --connection allows to specify a connection.

The table arguments define which table will be delete, by default all table.

Note that the --force option is needed to actually execute the deletion.

PropelParamConverter

You can use the Propel ParamConverter with the SensioFrameworkExtraBundle. You just need to put the right Annotation on top of your controller:

<?php

/**
 * @ParamConverter("post", class="BlogBundle\Model\Post")
 */
public function myAction(Post $post)
{
}

Your request needs to have an id parameter or any field as parameter (slug, title, ...).

The Annotation is optional if your parameter is typed you could only have this:

<?php

public function myAction(Post $post)
{
}

Exclude some parameters:

You can exclude some attributes from being used by the converter:

If you have a route like /my-route/{slug}/{name}/edit/{id} you can exclude name and slug by setting the option "exclude":

<?php

/**
 * @ParamConverter("post", class="BlogBundle\Model\Post", options={"exclude"={"name", "slug"}})
 */
public function myAction(Post $post)
{
}

UniqueObjectValidator

In a form, if you want to validate the unicity of a field in a table you have to use the UniqueObjectValidator. The only way to use it is in a validation.yml file, like this:

BundleNamespace\Model\User:
  constraints:
    - Propel\PropelBundle\Validator\Constraints\UniqueObject: username

For validate the unicity of more than just one fields:

BundleNamespace\Model\User:
  constraints:
    - Propel\PropelBundle\Validator\Constraints\UniqueObject: [username, login]

As many validator of this type as you want can be used.

Something went wrong with that request. Please try again.
