Configuration Overview

This following configuration example shows all the configuration defaults that the ORM resolves to:

doctrine:    orm:        auto_mapping: true        # the standard distribution overrides this to be true in debug, false otherwise        auto_generate_proxy_classes: false        proxy_namespace: Proxies        proxy_dir: "%kernel.cache_dir%/doctrine/orm/Proxies"        default_entity_manager: default        metadata_cache_driver: ~        query_cache_driver: ~        result_cache_driver: ~        report_fields_where_declared: false

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

Oracle DB

If the environment format configured in oracle does not meet doctrine requirements, you need to use the OracleSessionInit listener so that doctrine is aware of the format used by Oracle DB.

You can do so easily with

services:    oracle.listener:        class: Doctrine\DBAL\Event\Listeners\OracleSessionInit        tags:            - { name: doctrine.event_listener, event: postConnect }

The environment variables that doctrine is going to change in the Oracle DB session are:

NLS_TIME_FORMAT="HH24:MI:SS"NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"NLS_TIMESTAMP_FORMAT="YYYY-MM-DD HH24:MI:SS"NLS_TIMESTAMP_TZ_FORMAT="YYYY-MM-DD HH24:MI:SS TZH:TZM"

Caching Drivers

You can use a Symfony Cache pool by using the pool type and creating a cache pool through the FrameworkBundle configuration. The service type lets you define the ID of your own caching service.

The following example shows an overview of the caching configurations:

doctrine:    orm:        auto_mapping: true        # With no cache set, this defaults to a sane 'pool' configuration        metadata_cache_driver: ~        # the 'pool' type requires to define the 'pool' option and configure a cache pool using the FrameworkBundle        result_cache_driver:            type: pool            pool: doctrine.result_cache_pool        # the 'service' type requires to define the 'id' option too        query_cache_driver:            type: service            id: App\ORM\MyCacheServiceframework:    cache:        pools:            doctrine.result_cache_pool:                adapter: cache.app

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, 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.root_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.

Filters Configuration

You can easily define doctrine filters in your configuration file:

doctrine:    orm:        filters:            myFilter:                class: MyVendor\MyBundle\Filters\MyFilter                enabled: true                parameters:                    myParameter: myValue                    mySecondParameter: mySecondValue

myFilter: Filter identifier (Required)
class: Filter target class (Required)
enabled: Enable/Disable the filter by default (Optional - Default disabled)
parameters:: Set default parameters (Optional)
myParameter: myValue: Bind the value myValue to the parameter myParameter (Optional)

Autowiring multiple Entity Managers

You can autowire different entity managers by type-hinting your service arguments with the following syntax: Doctrine\ORM\EntityManagerInterface $<entity manager>EntityManager. For example, to inject a purchase_logs entity manager use this:

-     public function __construct(EntityManagerInterface $entityManager)+     public function __construct(EntityManagerInterface $purchaseLogsEntityManager)    {        $this->entityManager = $purchaseLogsEntityManager;    }

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.

When specifying a url parameter, any information extracted from that URL will override explicitly set parameters unless override_url is set to true. An example database URL would be mysql://snoopy:redbaron@localhost/baseball, and any explicitly set driver, user, password and dbname parameter would be overridden by this URL. See the Doctrine DBAL documentation for more information.

Besides default Doctrine options, there are some Symfony-related ones that you can configure. The following block shows all possible configuration keys:

doctrine:    dbal:        url:                      mysql://user:secret@localhost:1234/otherdatabase # this would override the values below        dbname:                   database        host:                     localhost        port:                     1234        user:                     user        password:                 secret        dbname_suffix:            _test        driver:                   pdo_mysql        driver_class:             MyNamespace\MyDriverImpl        options:            foo: bar        path:                     "%kernel.project_dir%/var/data.db" # SQLite specific        memory:                   true                               # SQLite specific        unix_socket:              /tmp/mysql.sock        persistent:               true        MultipleActiveResultSets: true                # pdo_sqlsrv driver specific        pooled:                   true                # Oracle specific (SERVER=POOLED)        protocol:                 TCPIP               # IBM DB2 specific (PROTOCOL)        server:                   my_database_server  # SQL Anywhere specific (ServerName)        service:                  true                # Oracle specific (SERVICE_NAME instead of SID)        servicename:              MyOracleServiceName # Oracle specific (SERVICE_NAME)        sessionMode:              2                   # oci8 driver specific (session_mode)        default_dbname:           database            # PostgreSQL specific (default_dbname)        sslmode:                  require             # PostgreSQL specific (LIBPQ-CONNECT-SSLMODE)        sslrootcert:              postgresql-ca.pem   # PostgreSQL specific (LIBPQ-CONNECT-SSLROOTCERT)        sslcert:                  postgresql-cert.pem # PostgreSQL specific (LIBPQ-CONNECT-SSLCERT)        sslkey:                   postgresql-key.pem  # PostgreSQL specific (LIBPQ-CONNECT-SSLKEY)        sslcrl:                   postgresql.crl      # PostgreSQL specific (LIBPQ-CONNECT-SSLCRL)        wrapper_class:            MyDoctrineDbalConnectionWrapper        charset:                  ~                   # RDBMS-specific.

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

doctrine:    dbal:        default_connection:       default        connections:            default:                dbname:           Symfony2                user:             root                password:         null                host:             localhost            customer:                dbname:           customer                user:             root                password:         null                host:             localhost

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.

Autowiring multiple Connections

You can autowire different connections by type-hinting your service arguments with the following syntax: Doctrine\DBAL\Connection $<connection name>Connection. For example, to inject a connection with the name purchase_logs use this:

-     public function __construct(Connection $connection)+     public function __construct(Connection $purchaseLogsConnection)    {        $this->connection = $purchaseLogsConnection;    }
