Working With Silex

The PropelServiceProvider provides integration with Propel.

Parameters

• propel.path (optional): The path in wich Propel.php will be found. Usually, for PEAR installation, it is propel while for Git installation it is vendor/propel/runtime/lib. Default is /full/project/path/vendor/propel/runtime/lib.

• propel.config_file (optional): The name of Propel configuration file with full path. Default is /full/project/path/build/conf/projectname-conf.php

• propel.model_path (optional): Path to where model classes are located. Default is /full/project/path/build/classes

• propel.internal_autoload (optional): Setting to true, forces Propel to use its own internal autoloader, instead of Silex one, to load model classes. Default is false

Tip
It's strongly recommanded to use absolute paths for previous options.

Services

No service is provided.

Propel configures and manages itself by using static methods, so no service is registered into Application. Actually, the PropelServiceProvider class initializes Propel in a more "Silex-ian" way.

Registering

Make sure you place a copy of Propel in vendor/propel or install it through PEAR, or Composer.

For more informations consult the Propel documentation:

<?php

$app['autoloader']->registerNamespaces(array(
    'Propel\Silex'  => __DIR__ . '/../../vendor/propel/propel-service-provider/src',
));

$app->register(new Propel\Silex\PropelServiceProvider(), array(
    'propel.path'        => __DIR__.'/path/to/Propel.php',
    'propel.config_file' => __DIR__.'/path/to/myproject-conf.php',
    'propel.model_path'  => __DIR__.'/path/to/model/classes',
));

Alternatively, if you 've installed Propel by Git in vendor/propel and you built your model with default Propel generator options:

<?php

$app->register(new Propel\Silex\PropelServiceProvider());

We can consider "default" Propel generator options:

• Put build.properties and schema.xml files into the main directory project, usually where file index.php is located.

• In build.properties file, define only propel.database, propel.project and propel.namespace.autopackage properties.

Usage

You'll have to build the model by yourself. According to Propel documentation, you'll need three files:

• schema.xml which contains your database schema;

• build.properties more information below;

• runtime-conf.xml which contains the database configuration.

Use the propel-gen script to create all files (SQL, configuration, Model classes).

By default, the PropelServiceProvider relies on the Silex autoloader you have to configure to load model classes. Of course, the Silex autoloader needs the model to be built with namespaces, so be sure to set this property into the build.properties file:

propel.namespace.autopackage = true

The recommended configuration for your `build.properties` file is:

propel.project      = <project_name>

propel.namespace.autoPackage = true
propel.packageObjectModel    = true

# Enable full use of the DateTime class.
# Setting this to true means that getter methods for date/time/timestamp
# columns will return a DateTime object when the default format is empty.
propel.useDateTimeClass = true

# Specify a custom DateTime subclass that you wish to have Propel use
# for temporal values.
propel.dateTimeClass = DateTime

# These are the default formats that will be used when fetching values from
# temporal columns in Propel. You can always specify these when calling the
# methods directly, but for methods like getByName() it is nice to change
# the defaults.
# To have these methods return DateTime objects instead, you should set these
# to empty values
propel.defaultTimeStampFormat =
propel.defaultTimeFormat =
propel.defaultDateFormat =

If you plan to build your model without using namespaces, you need to force Propel to use its internal autoloader. Do this by setting the option propel.internal_autoload to true.
