In certain PHPDoc blocks for functions, the @return type is not of the right type. This causes auto-completion issues in various IDEs (I'm using PhpStorm).

For example, in \Doctrine\ODM\MongoDB\DocumentManager on line #341 the ->createQueryBuilder($documentName = null) function.

/**

• Create a new Query instance for a class.
  *
• @param string $documentName The document class name.
• @return Document\ODM\MongoDB\Query <--------------------------- MUST BE Query\Builder !
  */
  public function createQueryBuilder($documentName = null) { return new Query\Builder($this, $this->cmd, $documentName); }

Here is my class hierarchy (classes & attributes renamed for a better understanding) :

 
/** @Document @InheritanceType("COLLECTION_PER_CLASS") **/
class Parent {
    /** @ReferenceOne(targetDocument="Child") **/
    protected $child;
}

/** @Document **/
class Child extends Parent {
}

When doing :

$parent->setXXX($value);
$parent->getChild()->setXXX($value2)

the $parent->getChild() document is saved to the Parent collection.

It looks like the problems lies in UnitOfWork::executeUpdates :

 
if (get_class($document) == $className || $document instanceof Proxy && $document instanceof $className) {

$child_document is an instance of Proxy (ChildProxy) and also an instance of Parent => saved using the Parent persister.

Shouldn't the test be : get_class($document) == $className || get_class($document) == $className_of_Proxy ?

As a side note : why "if ($class->isEmbeddedDocument)

" is within the foreach and not a "if ($class->isEmbeddedDocument)

" at the beginning of the method ?

"Near" statement does not work for me. The following code returns all cities from collection:

$cities = $this->dm->createQuery('City')
    ->field('coordinates')->near(50, 60)
    ->execute();

Could you please fix it?

I have described the issue in detail here: https://github.com/doctrine/mongodb-odm/issues/124

Annotation class HasLifecycleCallbacks is missing in Doctrine\ODM\MongoDB\Mapping\Annotations

The XSD file for XML mappings (http://www.doctrine-project.org/schemas/odm/doctrine-mongo-mapping.xsd) appears to be incomplete:

• Only document is allowed as root tag, not mapped-superclass or embedded-document
• The name attribute for the document tag is not allowed according to the XSD file
• The fieldName, index and unique attributes for the field tag is not allowed according to the XSD file

These are the problems I discovered at the moment, I haven't yet checked for more problems. The XSD file probably needs a bigger update.

Attached is a patch file that adds the missing attributes, I haven't dug into Doctrine enough to create the mapped-superclass or embedded-document tags.

When using ReferenceOne or ReferenceMany , doctrine will create fully-qualified reference to the object (with all fields: '$id', '$ref', '$db') even when reference is within same $db.

This approach causes several problems: for example we use mongo database as a template for new clients - when new client registers, template database is copied for him. But since it contains hardcoded $db - copy operation becomes resource consuming, since we have to loop through every document of every collection and fix $db reference.

Also maintenance suffers, since you can't easily rename database when required.

Is it possible to omit $db part when referencing document from same db?

Description of the problem here:

Problem with the unincisive toArray() method.

I think that is a documentation issue, in http://www.doctrine-project.org/docs/mongodb_odm/1.0/en/reference/query-builder-api.html (15.3. Modifier Operations) the queries are like:

$dm->createQueryBuilder('User')

>field('password')>set('newpassword')

>field('username')>equals('jwage')

->getQuery()
->execute();

But it is missing the update(), it should be like:

$dm->createQueryBuilder('User')

->update()
>field('password')>set('newpassword')

>field('username')>equals('jwage')

->getQuery()
->execute();

All the queries in that section have similar issue

I'm using the latest version of Doctrine ODM (fresh from Git).

I have three levels of Documents (Two embedded); Category -> EmbedsMany: Post -> EmbedsMany PostVersion.

Step-by-step:

1. Make a new Post (Post1), 2 PostVersions (PostVersion1 and 2) and a Category
2. Add Post1 to Category
3. Persist Category, Flush, Clear
4. Retrieve Category
5. Make a new Post (Post2) and 2 PostVersions(PostVersion3 and 4)
6. Add Post2 to Category
7. Flush

If you're following properly, at this stage in the database there should be:
1 Category,
2 Posts
4 PostVersions ... 2 PostVersions in each Post

However, what actually happens is:
1 Category,
2 Posts
4 PostVersions ... 4 PostVersions in Post1, 0 PostVersions in Post2

On StackOverflow: http://bit.ly/ekFbe2
Testcase Gist: https://gist.github.com/920914

A work around is to make Post2 and add it to Category, flush, then make new PostVersions and flush again.

I did some debugging but I don't know enough about the internals to fix the issue.

Documents

class Test 
{
.
.
.
/**
 * @EmbedOne(targetDocument="Location", name="l")
*/
private $location;
.
.
.
}

/** @EmbeddedDocument */
class Location
{
    /**
	 * @Field(type="float", name="y")
	 */
    public $lat;

    /**
	 * @Field(type="float", name="x")
	 */
    public $lng;

	public function __construct($latitude,$longitude) {
		$this->lat = $latitude;
		$this->lng = $longitude;
	}
}

Update query:

$dm->createQueryBuilder('Test')
->update()
->field('id')->equals(123)
->field('l')->set(new Location(39, 32);
->getQuery(array('upsert' => true))
->execute();

Result of this query is

"l": {
    "lat": 39,
    "lng": 32
},

however, it should be

"l": {
    "y": 39,
    "x": 32
},

also field function can support field name of the class on update queries, as follows

$dm->createQueryBuilder('Test')
->update()
->field('id')->equals(123)
->field('location')->set(new Location(39, 32);
->getQuery(array('upsert' => true))
->execute();

I have thoose examples :

/** @Document 
 * @InheritanceType("SINGLE_COLLECTION")
 * @DiscriminatorField(fieldName="type")
 * @DiscriminatorMap({"Test\Product"="Product", "Test\Year"="Year"})
*/
Attributes {
   /** @Id */
   protected $_id;
}

/** @Document */
class Product extends Attributes {}

/** @Document */
class Year extends Attributes {}

/**
 * Classe de base pour les différents contenus
 * @Document
 * @InheritanceType("SINGLE_COLLECTION")
 * @DiscriminatorField(fieldName="type")
 * @DiscriminatorMap({"Test\Document"="Document", "Test\Infos"="Infos"})  
 */
class Content
{
   /** protected $_id */
    /** @ReferenceMany */
    protected $_attributes;
}

And the querying stuff

//and the query : 
$queryBuilder = $dm->createQueryBuilder('Test\DOcument');
//...
$attribute1Ref = $dm->createDBRef($attribute1Object);
$attribute2Ref = $dm->createDBRef($attribute2Object);
$queryBuilder->field('_attributes')->all(array($attribute1Ref, $attribute2Ref));
$queryBuilder->getQuery()->execute();//Won't work as the generated query won't specify the "_doctrine_class_name" value.

Proposed patch in DocumentManager :

    /**
     * Returns a DBRef array for the supplied document.
     *
     * @param mixed $document A document object
     * @param array $referenceMapping Mapping for the field the references the document
     *
     * @return array A DBRef array
     */
    public function createDBRef($document, array $referenceMapping = null)
    {
        $className = get_class($document);
        $class = $this->getClassMetadata($className);
        $id = $this->unitOfWork->getDocumentIdentifier($document);

        $dbRef = array(
            $this->cmd . 'ref' => $class->getCollection(),
            $this->cmd . 'id'  => $class->getDatabaseIdentifierValue($id),
            $this->cmd . 'db'  => $this->getDocumentDatabase($className)->getName()
        );

        // add a discriminator value if the referenced document is not mapped explicitely to a targetDocument
        if ($referenceMapping && ! isset($referenceMapping['targetDocument'])) {
            $discriminatorField = isset($referenceMapping['discriminatorField']) ? $referenceMapping['discriminatorField'] : '_doctrine_class_name';
            $discriminatorValue = isset($referenceMapping['discriminatorMap']) ? array_search($class->getName(), $referenceMapping['discriminatorMap']) : $class->getName();
            $dbRef[$discriminatorField] = $discriminatorValue;
+        }  elseif ($referenceMapping === null) {
+            $dbRef['_doctrine_class_name'] = $class->getName();
+        }
        return $dbRef;
    }

It seems that if you just call upsert(true) in a update request, it won't be enough. You have to calm getQuery(array('upsert' => true)) as well in order to have the 'insert if not exist' working.

We persist a document a1 containing an embedded document a1.1 which itself contains another embedded document a1.1.1. When the embedded document a1.1 is moved to another document of another collection b1 and needs to get persisted as embedded document b1.1 the embedded document a1.1.1 (which is now part of b1.1, too) is not saved as an embedded document of b1.1.

Example: We use a version object which contains a pageversion as an embedded document. This page object contains multiple elements (stored as embedded documents) which themselves contain several parameter objects (stored as embedded document of elements). Now assume we have such a persisted version and want to "copy" the pageversion in another collection. So we generate a new page object, and add to this page all elements of the persisted pageversion. If we now persist this page, the representation in mongodb contains all elements but not any parameters, which should be part of the page as well (as they are part of an element).

HI all,

I am working on a project where I would like to use mongoDB ODM. But while following this tutotorial : http://docs.doctrine-project.org/projects/doctrine-mongodb-odm/en/latest/reference/introduction.html, it appears to me that the download odm library doesn't work with the code: missing code or undefined classes. Therefore I woulld like to know what's the corresponding version mongodb ODM of the tutorial.

Thank's in advance

All is there: https://gist.github.com/1682981

Reference objects identifiers are stored as '$id' in database when Embedded objects identifiers are stored as '_id'. When querying a collection by embedded objects identifier, DocumentPersister->prepareQueryValue() converts it to '$id' although it is stored in DB as '_id'. So querying for reference object ids work but embedded objects do not.

DocumentPersister->prepareQueryValue() first checks if field has TargetDocument mapping, if it is true it checks if field is target document's identifier, if this also returns true
it prepares the field as '$id' without looking at if it is Embedded or Reference object ... If TargetDocument it is a Reference object it works since Reference objects identifiers are stored as '$id' but if TargetDocument is Embedded object, query returns empty as theres no field such '$id' in EmbeddedObject, identifier is '_id' instead..

Is this a bug / issue or am i missing something?

When using the @Timestamp mapping type for a class Doctrine uses MongoTimestamp and it creates very incorrect times in the DB. According to PHP documentation, you should not use MongoTimestamp for creating timestamps, instead MongoDate should be used.

I've attached a patch that changes it to MongoDate and this works splendid when you assign a timestamp to a @Timestamp value

	/**
	 * @Field(type="timestamp")
	 */
	protected $created_on;

	/**
	 * @Field(type="timestamp")
	 */
	protected $updated_on;

	public function __construct($options = NULL)
	{
		$this->created_on = $this->updated_on = time();
		parent::__construct($options);
	}

Doctrine\ODM\MongoDB\Query\Expr::getNewObj() uses Doctrine\ODM\MongoDB\Persisters\DocumentPersister::prepareQuery() method for preparing newObj. However, prepareQuery is not suitable for that.

The first lines in prepareQuery method should apply to find queries only:

if (is_scalar($query) || $query instanceof \MongoId) {
$query = array('_id' => $query);
}
if ($this->class->hasDiscriminator() && ! isset($query[$this->class->discriminatorField['name']])) {
$discriminatorValues = $this->getClassDiscriminatorValues($this->class);
$query[$this->class->discriminatorField['name']] = array('$in' => $discriminatorValues);
}

Recommendation: DocumentPersister should introduce a new method, such as prepareNewObj($newObj) for preparing the newObj array. Expr::getNewObj() should be change to invoke the new method.

On the master branch, a notice is thrown on line 531 of the DocumentPersister for an undefined index 'criteria'. This is when using the Yaml driver.

https://github.com/doctrine/mongodb-odm/blob/master/lib/Doctrine/ODM/MongoDB/Persisters/DocumentPersister.php#L531

Mappings:

/**
 * @Field(type="date", name="scheduled_at")

private $scheduledAt;

/**
 * @Field(type="date", name="completed_at")
 */
private $completedAt;

Query:

$qb->field('scheduledAt')->lte($now)
   ->addOr($qb->expr()->field('completedAt')->lte($now))
   ->addOr($qb->expr()->field('completedAt')->equals(null))
   ->sort('scheduledAt', 'asc');

Expected result:

db.foo.find({
    "scheduled_at": { "$lte": new Date(...) }, 
    "$or": [ 
        { "completed_at": {  "$lte": new Date(...) } }, 
        { "completed_at": null } ] 
})
.sort({ "scheduled_at": 1 });

Actual result:

db.foo.find({
    "scheduled_at": { "$lte": new Date(...) }, 
    "$or": [ 
        { "completedAt": {  "$lte": new Date(...) } }, 
        { "completedAt": null } ] 
})
.sort({ "scheduledAt": 1 });

I have a listener who listens on onFlush event,
i have a document and change a property (integer) in it and call $uow->recomputeSingleDocumentChangeSet().
The result is that all references are added twice.

If i remove the call to $uow->recomputeSingleDocumentChangeSet() all is fine.

Here's my document (notice references added twice on children property):

array (
'children' =>
array (
0 =>
array (
'$ref' => 'block',
'$id' => new MongoId("4d8b663638b6180803000005"),
'$db' => 'app_jules',
'_doctrine_class_name' => 'Design\\PageBundle\\Document
StrategyBlock',
),
1 =>
array (
'$ref' => 'block',
'$id' => new MongoId("4d8b663638b6180803000005"),
'$db' => 'app_jules',
'_doctrine_class_name' => 'Design\\PageBundle\\Document
StrategyBlock',
)
),
'order' => 0,
'parent' =>

'$db' => 'app_jules',
'_doctrine_class_name' => 'Design\\PageBundle\\Document
ContainerBlock',
),
'type' => 'container',
)

EDIT: if i clear() the $children ArrayCollection before calling $uow->recomputeSingleDocumentChangeSet() all is fine

I tried to reproduce it in a test-case but the result wasn't successful

After ClassMetaData is awakened it looses the "file" property and that breaks our File model.
File::count() returns 0

I dumped ClassMetaData object with caching enabled and disabled. Here's the diff:

146c146
< [file] =>
—
> [file] => file
149a150,180
> [0] => Array
> (
> [keys] => Array
> (
> [uploaded_at] => 1
> )
>
> [options] => Array
> (
> [safe] => true
> [unique] =>
> )
>
> )
>

The first line is the missing file value. The second block appears to be missing indexes but I'm guessing this information should not be serialized.

Notice: Undefined variable: file in /projects/tbi/vendors/doctrine/odm/lib/vendor/doctrine-mongodb/lib/Doctrine/MongoDB/GridFS.php on line 112

I have a document like this:

/** @Document */
class Page
{
/** @Id */
protected $id;

/** @ReferenceMany(sort=

) */
protected $blocks;
}

If i have well understood things, i can do:

$blocks = $dm->getRepository('Page')>find($id)>getBlocks();

blocks should now be sorted by $order property.

This behaviour doesn't seems to work (or maybe i'm missing something).
In the attachment there's a test case

i made the priority major because in my case i haven't found a workaround (i'm using nested referenceMany, a child can have children, which can have children, ..).

Hi,

Bug checked on versions:
doctrine/mongodb-odm (1.0.0-BETA7)
doctrine/mongodb-odm-bundle (v3.0.0-BETA3)
and
doctrine/mongodb-odm (dev-master 6fd7a46)
doctrine/mongodb-odm-bundle (dev-master 23c08a4)

I've created unique index on embedded document and ODM seem not to be working properly. When unique index is violated MongoCursorException is thrown and this behavior is desired.
But, the document sometimes is persisted anyway. Document structure is invalid.

Thrown exception:
mymongoserver.xx:27017: E11000 duplicate key error index: prj.Grid.$boxes_offer_$id_1_boxes_tag_$id_1 dup key: { : ObjectId('51555bbe31bcb2c70e000001'), : "dom" }

Grid document sketch:

unique index on boxes.tag

Any help would be appreciated.

I noticed that the references() method does not support fields on embedded objects, as the argument to the preceding field() method will be passed into getFieldMapping() and trigger an exception. I suppose a solution would require multiple calls to getFieldMapping() in order to dive into the embedded object's class metadata.

To demonstrate, below is an example of a UserRepository class. The User document contains an embeddedObject that itself references another User:

class UserRepository extends DocumentRepository
{ 
    public function findByEmbeddedObjectReference(User $user)
    {
        return $this->createQueryBuilder()
            ->field('embeddedObject.user.$id')->equals($user->getId())
//          ->field('embeddedObject.user')->references($user)
            ->getQuery()
            ->execute();
    }
}

Using field()/equals() works fine as an alternative to references(), so there is no urgent need for this feature.

I cant´t reproduce the Bi-Directional References with my own example or the example of the documentation.
Perhaps the documentation is not up to date or their ist a bug.

BlogPost.php
<?php

/** @Document */
class BlogPost
{
/** @Id */

$comment1->title = 'testcommenttitle1';

$comment2 = new PostComment();
$comment2->title = 'testcommenttitle2';

$comment3 = new PostComment();
$comment3->title = 'testcommenttitle3';

$dm->persist($comment1);
$dm->persist($comment2);
$dm->persist($comment3);
$dm->flush();

echo $post->id;

/*$posts = $dm->createQueryBuilder('BlogPost')
->getQuery();*/

$post = $dm->getRepository('BlogPost')->find('4dd45739f563724c23000002');

Zend_Debug::dump($post);
$comments = $post->getComments();

------------------------
In the documentation the example is
$post1->setUser($user);
But the only working for me is:
$post->setTitle = 'testtitle';

Anyway, I can´t get the Comments from the mongodb.
I always get this error.
Fatal error: Call to undefined method BlogPost::getComments()
This is a correct error message because BlogPost really dont have a getComments()
method. How do I get my Comments then?
Any help would be great.

Greetings tronga

In the documentation exemples for update queries :
http://www.doctrine-project.org/docs/mongodb_odm/1.0/en/reference/query-builder-api.html#update-queries

it doesn't mention a update() function call any more in update queries.

Did I miss something?

When using the Yaml driver the ClassMetadata generation process won't create and use the indicated custom repository class for an embedded document. From what I can see digging into the actual code, it will work when using the Annotations or XML drivers, but in the Yaml driver the call to setCustomRepositoryClass is inside of a conditional that only gets entered if the document type is 'document'.

I'm not completely sure, but from what I can see elsewhere in the code, it looks like mapped superclasses should also be able to have a custom repository class, but can't when using the Yaml driver.

So I reckon what would work would be to change the code as indicated below:

<<EXISTING CODE>>
//Doctrine/ODM/MongoDb/Mapping/Driver/YamlDriver.php, line 66
if ($element['type'] == 'document') {
if (isset($element['repositoryClass']))

} elseif ($element['type'] === 'mappedSuperclass')

elseif ($element['type'] === 'embeddedDocument')

<<TO THIS>>
if (isset($documentAnnot->repositoryClass))

Hi,

I'm implementing some functionality around filters which will ideally work for both ORM and ODM. The API for managing filters is different on `Doctrine\ORM\EntityManager` and `Doctrine\ODM\MongoDB\DocumentManager`, while the CouchDB implementation of ODM has no filter concept.

For example, ORM EntityManager has getFilters(), hasFilters(), while ODM MongoDB DocumentManager has getFilterCollection().

I was wondering what your thoughts were on defining the filter API in an interface, to improve consistency when implementing cross-library functionality?

Thanks,
Craig

I am not sure if it's supposed to be that @MappedSuperclass document can define @ChangeTrackingPolicy for multiple documents but in fact it does not work.

In other words in the case below:
===================================================

/**

• @MappedSuperclass
• @InheritanceType("COLLECTION_PER_CLASS")
• @ChangeTrackingPolicy("DEFERRED_EXPLICIT")
  */
  abstract class MappedDocument
  {
  }

/**

• @Document(collection="chart")
  */
  class Chart extends MappedDocument
  {
  }

===================================================

class Chart

• has InheritanceType = INHERITANCE_TYPE_COLLECTION_PER_CLASS which is expected
• but ChangeTrackingPolicy = CHANGETRACKING_DEFERRED_IMPLICIT (value by default) which is NOT expected.

At the same time if to define ChangeTrackingPolicy in the Chart class instead of MappedDocument it works as expected.

@ReferenceMany doesn't seem to work when used within a child class unless I specify @InheritanceType("CLASS_PER_COLLECTION") (which is fine b/c that works for our architecture)

Here is an example from our code:

//Parent Class

use Doctrine\Common\Collections\ArrayCollection;

/**

• @Document(collection="homepages")
• @ChangeTrackingPolicy("DEFERRED_IMPLICIT")
• @Indexes({
• @Index(keys= {"vertical"="asc","ts"="desc"}

  , safe="true"),

• @Index(keys= {"ts"="desc"}

  , safe="true")

• })
  */
  class Homepage extends MappedDocument
  {

//** References
/**

• @ReferenceMany(targetDocument="Post")
• @var list<Post>
  */
  protected $touts;

}

//Child Class
/**

• @Document(collection="readmes")
• @ChangeTrackingPolicy("DEFERRED_IMPLICIT")
• @Indexes({
• @Index(keys= {"vertical"="asc"}

  , safe="true")

• })

  class Readme extends Homepage { //** References /** * @ReferenceMany(targetDocument="Post") * @var list<Post> */ protected $more_touts; }

Other types such as @ReferenceOne all work just fine
