Symfony2 MongoDB session storage

Important: This has been converted from a class that used Mandango, therefore the passing of Mongo to the service may not be correct. This is untested! PRs welcome :-)

These are also temporary instructions until I find the time to stick it all into a bundle and test it accordingly ;-)

1. Add this file somewhere in your project, and add the relevant namespace line, eg:

    namespace My\Bundle\Session;
   

2. Add the class as a service in config.yml or wherever your service configuration is:

    services:
        // ...
        session.storage.mongo:
            class: My\Bundle\Session\MongoDBSessionStorage
            arguments:
                con: "%however.you.get.mongo%"
                options: "%mongo.session.options%"
   

3. Add session options into your parameters (maybe in config.yml or parameters.yml):

    parameters:
        // ...
        mongo.session.options:
            db_name: myMongoDBName
            collection: session
   

4. Configure the session to use your new service, in config.yml:

    framework:
        session:
            storage_id: session.storage.mongo
