If each environment requires a different MongoDB connection URI, you can define it as an environment variable and reference it in the bundle's config:
|
If you wish to use memcached to cache your metadata, you need to configure the
Memcached
instance; for example, you can do the following:
1 # app/config/config.yml
doctrine_mongodb:
default_database: hello_%kernel.environment%
connections:
default:
server: mongodb://localhost:27017
options: {}
document_managers:
default:
mappings:
App: ~
metadata_cache_driver:
type: memcached
class: Symfony\Component\Cache\Adapter\MemcachedAdapter
host: localhost
port: 11211
instance_class: Memcached

Mapping Configuration
Explicit definition of all the mapped documents is the only necessary configuration for the ODM and there are several configuration options that you can control. The following configuration options exist for a mapping:
type
One ofattribute
,xml
,php
orstaticphp
. This specifies which type of metadata type your mapping uses.dir
Path to the mapping or document 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 documents of this mapping share. This prefix should never conflict with prefixes of other defined mappings otherwise some of your documents cannot be found by Doctrine. This option defaults to the application namespace +Document
, for example for an application calledApp
, the prefix would beApp\Document
.alias
Doctrine offers a way to alias document namespaces to simpler, shorter names to be used in queries or for Repository access.is_bundle
This option is a derived value fromdir
and by default is set to true if dir is relative proved by afile_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.
To avoid having to configure lots of information for your mappings you should follow these conventions:
- Put all your documents in a directory
Document/
inside your project. For examplesrc/Document/
. - If you are using xml or php mapping put all your configuration files
into either the
config/doctrine/
directory (requires Symfony 5.4 or later) or theResources/config/doctrine/
directory suffixed with mongodb.xml, mongodb.yml or mongodb.php respectively. - Attributes are assumed if a
Document/
but noconfig/doctrine/
orResources/config/doctrine/
directory is found.
The following configuration shows a bunch of mapping examples:
1 doctrine_mongodb:
document_managers:
default:
mappings:
App: ~
App2: xml
App3: { type: attribute, dir: Documents/ }
App4: { type: xml, dir: config/doctrine/mapping }
App5:
type: xml
dir: my-app-mappings-dir
alias: AppAlias
doctrine_extensions:
type: xml
dir: "%kernel.project_dir%/src/vendor/DoctrineExtensions/lib/DoctrineExtensions/Documents"
prefix: DoctrineExtensions\Documents\
alias: DExt

Custom Types
Custom types can come in handy when you're missing a specific mapping type or when you want to replace the existing implementation of a mapping type for your documents.
Filters
Filter classes may be used in order to add criteria to ODM queries, regardless of where those queries are created within your application. Typically, filters will limit themselves to operating on a particular class or interface. Filters may also take parameters, which can be used to customize the injected query criteria.
Filters may be registered with a document manager by using the following syntax:
Unlike ORM, query parameters in MongoDB ODM may be non-scalar values. Since
such values are difficult to express in XML, the bundle allows JSON strings
to be used in |
Multiple Connections
If you need multiple connections and document managers you can use the following syntax:
1 doctrine_mongodb:
default_database: hello_%kernel.environment%
default_connection: conn2
default_document_manager: dm2
connections:
conn1:
server: mongodb://localhost:27017
conn2:
server: mongodb://localhost:27017
document_managers:
dm1:
connection: conn1
database: db1
metadata_cache_driver: array
mappings:
App: ~
dm2:
connection: conn2
database: db2
mappings:
AnotherApp: ~

Now you can retrieve the configured services connection services:
And you can also retrieve the configured document manager services which utilize the above connection services:
Connecting to a pool of mongodb servers on 1 connection
It is possible to connect to several mongodb servers on one connection if
you are using a replica set by listing all of the servers within the connection
string as a comma separated list and using replicaSet
option.
Where mongodb-01, mongodb-02 and mongodb-03 are the machine hostnames. You can also use IP addresses if you prefer.
Please refer to Replica Sets manual of MongoDB PHP Driver for further details. |
Using Authentication on a Database Level
MongoDB supports authentication and authorisation on a database-level. This is mandatory if you have e.g. a publicly accessible MongoDB Server. To make use of this feature you need to configure credentials for each of your connections. Every connection needs also a database to authenticate against. The setting is represented by the authSource connection string. Otherwise you will get a auth failed exception.
Specifying a context service
The MongoDB driver supports receiving a stream context to set SSL and logging options. This can be used to authenticate using SSL certificates. To do so, create a service that creates your logging context:
Note: the class
option is not used when creating the service, but has to be
provided for the service definition to be valid.
You can then use this service in your configuration:
