    <p>I have a 2d index on a coordinates property of my document. Using the mongo shell, I can query the collection like this;</p> <pre><code>db.adverts.find({coordinates:{$near:[20,40]}}) </code></pre> <p>And that returns the following results, as expected;</p> <pre><code>{ "_id" : ObjectId("4fddac51352de93903000000"), "title" : "dummy #3", "coordinates" : { "longitude" : 22, "latitude" : 31 } } { "_id" : ObjectId("4fddac48352de95105000000"), "title" : "dummy #3", "coordinates" : { "longitude" : 20, "latitude" : 30 } } { "_id" : ObjectId("4fddaca4352de93703000000"), "title" : "dummy #3", "coordinates" : { "longitude" : 31, "latitude" : 22 } } { "_id" : ObjectId("4fdda6a2352de90a03000000"), "title" : "dummy title", "created" : ISODate("2012-06-17T09:42:58Z"), "coordinates" : { "longitude" : 54.1234, "latitude" : -1.234 } } { "_id" : ObjectId("4fdda6d8352de9c004000000"), "title" : "dummy title #2", "created" : ISODate("2012-06-17T09:43:52Z"), "coordinates" : { "longitude" : 54.34, "latitude" : -1.124 } } </code></pre> <p>However, using Doctrine as per the documentation to query the exact same collection, I get no results e.g.</p> <pre><code>$adverts = $dm-&gt;createQueryBuilder('Advert') -&gt;field('coordinates')-&gt;near(20, 40) -&gt;getQuery() -&gt;execute(); $adverts-&gt;count(); // =&gt; 0 </code></pre> <p>My advert yaml looks like this;</p> <pre><code>Advert: type: document collection: adverts fields: id: id: true title: type: string content: type: string created: type: date updated: type: date status: type: int distance: type: int indexes: coordinates: keys: coordinates: 2d referenceOne: owner: targetDocument: User embedOne: coordinates: targetDocument: Coordinates </code></pre> <p>And the Coordinates document is like this;</p> <pre><code>Coordinates: type: embeddedDocument fields: longitude: type: float latitude: type: float </code></pre> <p>Any ideas why using Doctrine's ODM would return zero results on the same query?</p> <p>UPDATE #1 It looks that there is a problem with Doctrine\MongoDB\Query\Builder::near() L363. The method parameter ignores the second value ($y). So only the first value is being passed to be executed.</p>

    1. COThis may be a silly question, but shouldn't coordinates be defined as a field in Advert.yaml since it is after all -a field-. Or is that the purpose of EmbedOne.

    2. COWhat does getQuery() returns? Also, be aware that MongoDB wants the order in the coordinates field to be: latitude, longitude. It does *not* care about what the fields are called.

    3. CODerick - getQuery() returns an instance of Doctrine\ODM\MongoDB\Query\Query. Geoist - the embedOne specifies the coordinates property

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
