Doctrine Configuration Reference (DoctrineBundle)

The DoctrineBundle integrates both the DBAL and ORM Doctrine projects in Symfony applications. All these options are configured under the doctrine key in your application configuration.

Note

When using XML, you must use the http://symfony.com/schema/dic/doctrine namespace and the related XSD schema is available at: https://symfony.com/schema/dic/doctrine/doctrine-1.0.xsd

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:

        memory:               true

        mapping_types:
            enum: string
        types:
            custom: App\DBAL\MyCustomType
    

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 are running a MariaDB database, you must prefix the server_version value with mariadb- (e.g. server_version: mariadb-10.4.14). This will change in Doctrine DBAL 4.x, where you must define the version as output by the server (e.g. 10.4.14-MariaDB).

Always wrap the server version number with quotes to parse it as a string instead of a float number. Otherwise, the floating-point representation issues can make your version be considered a different number (e.g. 5.7 will be rounded as 5.6999999999999996447286321199499070644378662109375).

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:

        connections:
            default:
                dbname:           Symfony
                user:             root
                password:         null
                host:             localhost

            customer:
                dbname:           customer

                server_version:   '8.2.0'
    

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. In a controller you can access it using the getConnection() method and the name of the connection:

        // ...

        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
        naming_strategy: doctrine.orm.naming_strategy.default
    

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.

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

Use any of the existing Symfony Cache pools or define new pools to cache each of Doctrine ORM elements (queries, results, etc.):

            pool: doctrine.result_cache_pool

        # in addition to Symfony Cache pools, you can also use the
        # 'type: service' option to use any service as the cache
        query_cache_driver:
            type: service
            id: App\ORM\MyCacheService
    

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 attribute (for PHP attributes; it's the default value), xml, php or staticphp. This specifies which type of metadata type your mapping uses.

3.0

The yml mapping configuration is deprecated and was removed in Doctrine ORM 3.0.

See Doctrine Metadata Drivers for more information about this option.

`dir`

Absolute path to the mapping or entity files (depending on the driver).

`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.

`alias`

Doctrine offers a way to alias entity namespaces to simpler, shorter names to be used in DQL queries or for Repository access.

`is_bundle`

This option is false by default and it's considered a legacy option. It was only useful in previous Symfony versions, when it was recommended to use bundles to organize the application code.

Custom Mapping Entities in a Bundle

Doctrine's auto_mapping feature loads attribute 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

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.yaml) 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 attributes.

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 (attribute, 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.

SSL Connection with MySQL

To securely configure an SSL connection to MySQL in your Symfony application with Doctrine, you need to specify the SSL certificate options. Here's how to set up the connection using environment variables for the certificate paths:
