Working With Symfony4

If you are interested to work with Propel2 with Symfony, you should consider using the PropelBundle.

Installation

The recommended way to install this bundle is to rely on Composer:

composer require propel/propel: ~2.0@beta
composer require propel/propel-bundle: ~4.0@dev

or, if you prefer to manually edit your composer.json file:

"require": {
    "propel/propel": "~2.0@beta",
    "propel/propel-bundle": "~4.0@dev"
}

Symfony Flex automatically creates a recipe and enables the PropelBundle.

Configuration

Symfony team recommends to use the .env file to store passwords and accessing data, so let’s open this file and add some environment variables, useful for Propel:

###> Propel configuration ###
DB_USER=your_username
DB_PWD=your_password
DB_HOST=your_host_usually_localhost
DB_NAME=your_db_name
###> Propel configuration ###

Now we’re ready to configure Propel. Let’s create the config/packages/propel.yml file and add the following minimal configuration:

propel:
    database:
        connections:
            default:
                adapter:    mysql
                user:       "%env(DB_USER)%"
                password:   "%env(DB_PWD)%"
                dsn:        "mysql:host=%env(DB_HOST)%;dbname=%env(DB_NAME)%;charset=UTF8"

That’s all! Propel now works in your Symfony4 application!

Schema.xml and model directory

Propel can auto-discover your schema file: create an src/propeldirectory an put there your schema.xml file.

To autoload your model classes without any effort, thanks to the predefined Symfony autoload, generate your model into App namespace.

<database name="default" namespace="App\Model">
.............
.............
</database>
