Download the PHP package pomm/pomm-service-provider without Composer

PommServiceProvider for Silex

This is the Pomm service provider for the Silex microframework.

Installation

There are numerous ways to install PommServiceProvider. The sortest one being to use this script. It will create directory tree structure and your composer.json file (See Composer section below).

Composer

Composer is the easiest way to get the Service provider installed and running. Just add your composer.json the following:

"pomm/pomm-service-provider":    "dev-master"

in the require section. Invoke « composer.phar install » and it should be installed with the Pomm library.

Git submodules

If you use git, use the submodules:

$ mkdir vendor
$ git submodule add git://github.com/chanmix51/PommServiceProvider.git vendor/ghub/PommServiceProvider
$ git submodule add git://github.com/chanmix51/Pomm.git vendor/pomm

Otherwise, you can just download the archive, expand it in a subdirectory and tell the autoloader that GHub\Silex\Pomm namespace is under the src project subdirectory.

Using Pomm Service

It is advised to split your application in 3 files:

bootstrap.php Where extensions are loaded and configured application.php Where you define your controllers. generate_model.php The CLI tool to scan the postgresql's schemas and generate the model files.

This way, the index.php file is reduced to its simplest expression:

<?php #index.php

require(__DIR__.'/../application.php');

$app->run();

The application.php itself is just composed by your controllers. It includes the configuration by requiring the bootstrap.php file:

<?php #bootstrap.php

require_once __DIR__.'/vendor/autoload.php';

$app = new Silex\Application();

// EXTENSIONS
...
# pomm
$app->register(
    new Pomm\Silex\PommServiceProvider(),
    array(
        'pomm.class_path' => __DIR__.'/vendor/pomm',
        'pomm.databases' => array(
            'default' => array(
                'dsn' => 'pgsql://user:pass@host:port/dbname',
            )))
        );

The PommServiceProvider class takes the following arguments:

• pomm.class_name: This is the service class to be used (optional) default is Pomm\Service. The given service class has to extend Pomm\Service.
• pomm.databases: an array of databases in the format 'name' => array('dsn' => $dsn, 'class' => 'My\\Database\\Class').

The extension will instanciate the Database class for each of your connection which does not mean it will open connections. Connections are opened if you perform a statement in a connection. If you want to use your own Database class, provide its full path in the class parameter. By default, this parameter is set to Pomm\Connection\Database.

In the example above, we register a Model namespace to the autoloader so generated files would be places in Model\DbName\SchemaName namespace.

Generating Map files

Create the following script:

<?php #generate_model.php

require __DIR__.'/bootstrap.php';

$scan = new Pomm\Tools\ScanSchemaTool(array(
    'schema' => 'YOUR SCHEMA',
    'database' => $app['pomm']->getDatabase(),
    'prefix_dir' => __DIR__.'/Model',
    ));
$scan->execute();
