[MODM-159] Querying a collection by Embedded objects identifier not working.

Wed, 30 Nov 2011 03:56:14 +0000

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?

[MODM-164] DocumentPersister's prepareQuery() method is not suitable for preparing newObj for update queries

Thu, 5 Apr 2012 06:47:40 +0000

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.

[MODM-137] Undefined index 'criteria' in DocumentPersister

Mon, 4 Apr 2011 18:50:06 +0000

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.

[MODM-170] Unique index on embedded document

Wed, 15 May 2013 10:58:29 +0000

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:

{ _id: boxes:[DBref(Offer), DBref(Offer), DBref(Offer)] tag: DBref(Tag) }

unique index on boxes.tag

Any help would be appreciated.

[MODM-163] @ReferenceMany and Inheritance

Thu, 1 Mar 2012 18:07:13 +0000

@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; }

If I don't add the @InheritanceType annotation the $more_touts data never gets persisted into the DB.
Other types such as @ReferenceOne all work just fine
