Configuration Overview
----------------------

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

.. code-block:: yaml

    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: 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.

Caching Drivers
~~~~~~~~~~~~~~~

For the caching drivers you can specify the values "array", "apc", "memcache", "memcached"
or "xcache".

The following example shows an overview of the caching configurations:

.. code-block:: yaml

    doctrine:
        orm:
            auto_mapping: true
            metadata_cache_driver: apc
            query_cache_driver: xcache
            result_cache_driver:
                type: memcache
                host: localhost
                port: 11211
                instance_class: Memcache

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.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:

.. code-block:: yaml

    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)

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.

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

.. configuration-block::

    .. code-block:: yaml

        doctrine:
            dbal:
                dbname:               database
                host:                 localhost
                port:                 1234
                user:                 user
                password:             secret
                driver:               pdo_mysql
                driver_class:         MyNamespace\MyDriverImpl
                options:
                    foo: bar
                path:                 %kernel.data_dir%/data.sqlite
                memory:               true
                unix_socket:          /tmp/mysql.sock
                wrapper_class:        MyDoctrineDbalConnectionWrapper
                charset:              UTF8
                logging:              %kernel.debug%
                platform_service:     MyOwnDatabasePlatformService
                schema_filter:        ^sf2_
                mapping_types:
                    enum: string
                types:
                    custom: Acme\HelloBundle\MyCustomType

    .. code-block:: xml

        <!-- xmlns:doctrine="http://symfony.com/schema/dic/doctrine" -->
        <!-- xsi:schemaLocation="http://symfony.com/schema/dic/doctrine http://symfony.com/schema/dic/doctrine/doctrine-1.0.xsd"> -->

                name="default"
                dbname="database"
                host="localhost"
                port="1234"
                user="user"
                password="secret"
                driver="pdo_mysql"
                driver-class="MyNamespace\MyDriverImpl"

                platform-service="MyOwnDatabasePlatformService"

                <doctrine:type name="custom">Acme\HelloBundle\MyCustomType</doctrine:type>
            </doctrine:dbal>
        </doctrine:config>

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

.. code-block:: yaml

    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]`` if the name of the connection.
