Pomm2 bundle for Symfony

Although this bundle usable already, it is a work in progress. New features will be added.

This bundle provides a pomm service to use the Pomm2 Model Manager with Symfony.

Note:

If you are looking for a bundle for Pomm 1.x then look up for pomm/pomm-bundle on packagist.

Installation

composer require pomm-project/pomm-bundle

Note:

Pomm bundle support symfony flex, the recipe add route for the profiler pannel and a minimal configuration with a db session loaded from DATABASE_URL environment variable.

Setup

Add the bundle in the app/AppKernel.php file:

<?php // app/AppKernel.php
// …
    public function registerBundles()
    {
        $bundles = [
        // other bundles
        new \PommProject\PommBundle\PommBundle(),
        // other bundles
        ];

Configuration

In the app/config folder, store your db connection parameters in parameters.yml:

parameters:
    db_host1: 127.0.0.1
    db_port1: 5432
    db_name1: my_db_name
    db_user1: user
    db_password1: pass

    db_host2: 127.0.0.1
#   etc.

Sensitive information such as database credentials should not be committed in Git. To help you prevent committing those files and folders by accident, the Symfony Standard Distribution comes with a file called .gitignore which list resources that Git should ignore, included this parameters.yml file. You can now refer to these parameters elsewhere by surrounding them with percent (%).

Add an entry in config.yml:

pomm:
    configuration:
        my_db1:
            dsn: "pgsql://%db_user1%:%db_password1%@%db_host1%:%db_port1%/%db_name1%"
            pomm:default: true
        my_db2:
            dsn: "pgsql://%db_user2%:%db_password2%@%db_host2%:%db_port2%/%db_name2%"
            session_builder: "pomm.session_builder"
    logger:
        service: "@logger"

And in routing_dev.yml:

_pomm:
    resource: "@PommBundle/Resources/config/routing.yml"
    prefix:   /_pomm

Command line interface

The Pomm CLI is available through the bin/console utility. It is possible to browse the database or to generate model files.

$ ./bin/console pomm:generate:relation-all -d src -a 'AppBundle\Model' my_db1 student

If you want generate schema, you need to use the model manager session builder:

pomm:
    configuration:
        my_db1:
            dsn: "pgsql://%db_user1%:%db_password1%@%db_host1%:%db_port1%/%db_name1%"
            session_builder: "pomm.model_manager.session_builder"

Using Pomm from the controller

The Pomm service is available in the DIC as any other service:

    function myAction($name)
    {
        $students = $this->get('pomm')['my_db2']
            ->getModel('\AppBundle\Model\MyDb1\PublicSchema\StudentModel')
            ->findWhere('name = $*', [$name])
            ;

        …

It is now possible to tune and create a model layer as described in the quick start guide.

Param converter

This bundle provide a param converter to convert request to a flexible entity. The converter search in the request the parameters with names matching primary key.

You can specify witch connexion use in the option:

/**
 * @ParamConverter("student", options={"session": "my_db2"})
 */
public function getAction(Student $student)

By default, the model used for find the entity is deduce by adding Model to entity class name. If you have a different class name, you can use the model option:

/**
 * @ParamConverter("student", options={"model": "StudentModel"})
 */
public function getAction(Student $student)

This feature require sensio/framework-extra-bundle.

Serializer

You can use the serializer component to serialize entities.

Property info

This bundle also provide property info support to retrieve flexible entity properties informations.

Poolers as service

If you need to add additional poolers into the session builder all you need to do is tag a service definition with pomm.pooler

Model and Model layer as a service

Model and model layer objects can be registered as a service. For this to work properly you have to tag your service correctly and remove class:session_builder from configuration.

Models must be tagged with pomm.model and layers with pomm.model_layer

Both of those tags have the following parameters:

• pooler which is the name of a default pooler service, if left blank the default is used
• session which is the name of a default session service this is used from, if left blank the default is used
