Question

I’m using DoctrineMongoDBBundle and want to get some records. In my repository class I have code:

return $this->createQueryBuilder()->field('categories.data')
    ->equals($categoryId)->getQuery()->execute();

In profiler’s log it generates absolutely working query:

db.recipe.find({ "categories.data": 16 }).sort([ ]);

When I run this query via console client it returns me record. But repository class get’s nothing.

My server’s log looks like this:

query test_database.recipe query: { $query: { categories.data: "2" }, $orderby: {} } ntoreturn:0 keyUpdates:0 nreturned:0 reslen:20 0ms

But if i run plain PHP script to get same data:

<?php 
$mongo = new Mongo();
$col = $mongo->test_database->recipe;

foreach ($col->find(array("categories.data" => 2)) as $r) {
  print_r($r);
}

I got result and server’s log looks like this:

query test_database.recipe query: { categories.data: 2 } ntoreturn:0 keyUpdates:0 nreturned:1 reslen:1037 0ms

so difference is:

query test_database.recipe query: { $query: { categories.data: "2" }, $orderby: {} } ntoreturn:0 keyUpdates:0 nreturned:0 reslen:20 0ms

query test_database.recipe query: { categories.data: 2 } ntoreturn:0 keyUpdates:0 nreturned:1 reslen:1037 0ms[/quote]

Checked both MongoDB 2.1.1 and 1.8.1, deps file:

[symfony]
    git=http://github.com/symfony/symfony.git
    version=origin/2.0

[doctrine-common]
    git=http://github.com/doctrine/common.git
    version=2.2.2

[doctrine-dbal]
    git=http://github.com/doctrine/dbal.git
    version=2.1.7

[doctrine]
    git=http://github.com/doctrine/doctrine2.git
    version=2.1.7

[doctrine-mongodb-odm]
    git=http://github.com/doctrine/mongodb-odm.git

[DoctrineMongoDBBundle]
    git=http://github.com/doctrine/DoctrineMongoDBBundle.git
    target=/bundles/Symfony/Bundle/DoctrineMongoDBBundle

Based on this log you shared:

query test_database.recipe query: { $query: { categories.data: “2” },
$orderby: {} } ntoreturn:0 keyUpdates:0 nreturned:0 reslen:20 0ms

query test_database.recipe query: { categories.data: 2 } ntoreturn:0
keyUpdates:0 nreturned:1 reslen:1037 0ms

You’re matching by the string "2" in the first query, but the integer 2 in the second. These are not equivalent in MongoDB. Consider:

$ mongo
MongoDB shell version: 2.0.7
connecting to: test
> db.foo.drop()
false
> db.foo.insert({x:1})
> db.foo.find({x:"1"})
> db.foo.find({x:1})
{ "_id" : ObjectId("502fb9f5b6b1fd9f6ea794a4"), "x" : 1 }

Have you tried casting $categoryId to an integer before using it in the query builder?
