The YAML mapping driver enables you to provide the ORM metadata in form of YAML documents.
|
||
|
|
|
||
|
|
The YAML mapping document of a class is loaded on-demand the first time it is requested and subsequently stored in the metadata cache. In order to work, this requires certain conventions:
|
||
|
|
|
||
|
|
* Each entity/mapped superclass must get its own dedicated YAML mapping document.
|
||
|
|
* The name of the mapping document must consist of the fully qualified name of the class, where namespace separators are replaced by dots (.).
|
||
|
|
* All mapping documents should get the extension ".dcm.yml" to identify it as a Doctrine mapping file. This is more of a convention and you are not forced to do this. You can change the file extension easily enough.

|
|
[php]
|
||
|
|
$driver->setFileExtension('.yml');
|
||
|
|
|
||
|
|
It is recommended to put all YAML mapping documents in a single folder but you can spread the documents over several folders if you want to. In order to tell the YamlDriver where to look for your mapping documents, supply an array of paths as the first argument of the constructor, like this:
|
||
|
|
|
||
|
|
[php]
|
||
|
|
// $config instanceof Doctrine\ORM\Configuration
|
||
|
|
$driver = new YamlDriver(array('/path/to/files'));
|
||
|
|
$config->setMetadataDriverImpl($driver);
|
||
|
|
|

As a quick start, here is a small example document that makes use of several common elements:
