Upserting Documents
|
||
|
|
===================
|
||
|
|
|
||
|
|
Upserting documents in the MongoDB ODM is easy. All you really have to do
|
||
|
|
is specify an ID ahead of time and Doctrine will perform an ``update`` operation
|
||
|
|
with the ``upsert`` flag internally instead of a ``batchInsert``.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
.. code-block:: php
|
||
|
|
|
||
|
|
<?php
|
||
|
|
|
||
|
|
$article = new Article();
|
||
|
|
$article->setId($articleId);
|
||
|
|
$article->incrementNumViews();
|
||
|
|
$dm->persist($article);
|
||
|
|
$dm->flush();
|
||
|
|
|
||
|
|
The above would result in an operation like the following:
|
||
|
|
|
||
|
|
.. code-block:: php
|
||
|
|
|
||
|
|
<?php
|
||
|
|
|
||
|
|
$articleCollection->update(
|
||
|
|
array('_id' => new MongoId($articleId)),
|
||
|
|
array('$inc' => array('numViews' => 1)),
|
||
|
|
array('upsert' => true, 'safe' => true)
|
||
|
|
);
|
||
|
|
|
||
|
|
The extra benefit is the fact that you don't have to fetch the ``$article`` in order
|
||
|
|
to append some new data to the document or change something. All you need is the
|
||
|
|
identifier.
