Ankit,
There is no facility in MongoDB to execute aggregate pipeline via the find query. You can find more details about the method used specifically for aggregate in MongoDB/PHP driver - http://www.php.net/manual/en/mongocollection.aggregate.php .
Frage
db.gfk_products.aggregate([
{$match : {product_id : '50910288'}},
{$project : {
features: "$features.key"
}}
])
db.gfk_products.find({
aggregate : [
{$match : {product_id : '50910288'}},
{$project : {
features: "$features.key"
}}
]
})
Don't know why! Second query is generated by mongodb adapter for cakephp.
$cond['conditions'] = array(
'aggregate' => array(
array(
'$match' => array(
'product_id' => $itemID
),
),
array(
'$project' => array(
'features' => '$features.key'
),
),
),
);
$result = $this->Product->find('all',$cond);
