Doctrine DBAL Configuration

DoctrineBundle supports all parameters that default Doctrine drivers accept, converted to the XML or YAML naming standards that Symfony enforces. See the Doctrine DBAL documentation for more information. The following block shows all possible configuration keys:

Note

The server_version option was added in Doctrine DBAL 2.5, which is used by DoctrineBundle 1.3. The value of this option should match your database server version (use postgres -V or psql -V command to find your PostgreSQL version and mysql -V to get your MySQL version).

If you don’t define this option and you haven’t created your database yet, you may get PDOException errors because Doctrine will try to guess the database server version automatically and none is available.

If you want to configure multiple connections in YAML, put them under the connections key and give them a unique name:

The database_connection service always refers to the default connection, which is the first one defined or the one configured via the default_connection parameter.

Each connection is also accessible via the doctrine.dbal.[name]_connection service where [name] is the name of the connection.

doctrine:

        auto_generate_proxy_classes: false
        proxy_namespace: Proxies
        proxy_dir: '%kernel.cache_dir%/doctrine/orm/Proxies'
        default_entity_manager: default
        metadata_cache_driver: array
        query_cache_driver: array
        result_cache_driver: array

There are lots of other configuration options that you can use to overwrite certain classes, but those are for very advanced use-cases only.

Shortened Configuration Syntax

When you are only using one entity manager, all config options available can be placed directly under doctrine.orm config level.

        filters:

This shortened version is commonly used in other documentation sections. Keep in mind that you can’t use both syntaxes at the same time.

Caching Drivers

The built-in types of caching drivers are: array, apc, apcu, memcache, memcached, redis, wincache, zenddata and xcache. There is a special type called service which lets you define the ID of your own caching service.

The following example shows an overview of the caching configurations:

        # each caching driver type defines its own config options
        metadata_cache_driver: apc
        result_cache_driver:
            type: memcache
            host: localhost
            port: 11211
            instance_class: Memcache
        # the 'service' type requires to define the 'id' option too
        query_cache_driver:
            type: service
            id: my_doctrine_common_cache_service

Mapping Configuration

Explicit definition of all the mapped entities is the only necessary configuration for the ORM and there are several configuration options that you can control. The following configuration options exist for a mapping:

type

One of annotation, xml, yml, php or staticphp. This specifies which type of metadata type your mapping uses.

dir

Path to the mapping or entity files (depending on the driver). If this path is relative it is assumed to be relative to the bundle root. This only works if the name of your mapping is a bundle name. If you want to use this option to specify absolute paths you should prefix the path with the kernel parameters that exist in the DIC (for example %kernel.project_dir%).

prefix

A common namespace prefix that all entities of this mapping share. This prefix should never conflict with prefixes of other defined mappings otherwise some of your entities cannot be found by Doctrine. This option defaults to the bundle namespace + Entity, for example for an application bundle called AcmeHelloBundle prefix would be Acme\HelloBundle\Entity.

alias

Doctrine offers a way to alias entity namespaces to simpler, shorter names to be used in DQL queries or for Repository access. When using a bundle the alias defaults to the bundle name.

is_bundle

This option is a derived value from dir and by default is set to true if dir is relative proved by a file_exists() check that returns false. It is false if the existence check returns true. In this case an absolute path was specified and the metadata files are most likely in a directory outside of a bundle.

Custom Mapping Entities in a Bundle

Doctrine’s auto_mapping feature loads annotation configuration from the Entity/ directory of each bundle and looks for other formats (e.g. YAML, XML) in the Resources/config/doctrine directory.

If you store metadata somewhere else in your bundle, you can define your own mappings, where you tell Doctrine exactly where to look, along with some other configurations.

If you’re using the auto_mapping configuration, you just need to overwrite the configurations you want. In this case it’s important that the key of the mapping configurations corresponds to the name of the bundle.

For example, suppose you decide to store your XML configuration for AppBundle entities in the @AppBundle/SomeResources/config/doctrine directory instead:

        ),
    ),
));

Mapping Entities Outside of a Bundle

You can also create new mappings, for example outside of the Symfony folder.

For example, the following looks for entity classes in the App\Entity namespace in the src/Entity directory and gives them an App alias (so you can say things like App:Post):

Detecting a Mapping Configuration Format

If the type on the bundle configuration isn’t set, the DoctrineBundle will try to detect the correct mapping configuration format for the bundle.

DoctrineBundle will look for files matching *.orm.[FORMAT] (e.g. Post.orm.yml) in the configured dir of your mapping (if you’re mapping a bundle, then dir is relative to the bundle’s directory).

The bundle looks for (in this order) XML, YAML and PHP files. Using the auto_mapping feature, every bundle can have only one configuration format. The bundle will stop as soon as it locates one.

If it wasn’t possible to determine a configuration format for a bundle, the DoctrineBundle will check if there is an Entity folder in the bundle’s root directory. If the folder exist, Doctrine will fall back to using an annotation driver.

Default Value of Dir

If dir is not specified, then its default value depends on which configuration driver is being used. For drivers that rely on the PHP files (annotation, staticphp) it will be [Bundle]/Entity. For drivers that are using configuration files (XML, YAML, …) it will be [Bundle]/Resources/config/doctrine.

If the dir configuration is set and the is_bundle configuration is true, the DoctrineBundle will prefix the dir configuration with the path of the bundle.
