Configuration Overview

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

1
2
3
4
5
6
7
8
9
10
11
12
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

1
2
3
4
5
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:

1
2
3
4
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\MyCacheService

framework:
    cache:
        pools:
            doctrine.result_cache_pool:
                adapter: cache.app

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, 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:

1
2
3
4
5
-     public function __construct(EntityManagerInterface $entityManager)
+     public function __construct(EntityManagerInterface $purchaseLogsEntityManager)
    {
        $this->entityManager = $purchaseLogsEntityManager;
    }

Doctrine DBAL Configuration

Note

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.

Note

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:

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:

1
2
3
4
5
-     public function __construct(Connection $connection)
+     public function __construct(Connection $purchaseLogsConnection)
    {
        $this->connection = $purchaseLogsConnection;
    }
