Updating multiple embedded docs in mongoDB - php

Question

I need to update multiple embedded docs in mongo using PHP. My layout looks like this:
{
_id: id,
visits : {
visitID: 12
categories: [{
catagory_id: 1,
name: somename,
count: 11,
duration: 122
},
{
catagory_id: 1,
name: some other name,
count: 11,
duration: 122
},
{
catagory_id: 2,
name: yet another name,
count: 11,
duration: 122
}]
}
}
The document can have more than one visit too.
Now i want to update 2 categories, one with id=1 and name=somename and the other with id=1 and name=some_new_name. Both of them should inc "count" by 1 and "duration" by 45.
First document exists, but second does not.
Im thinking of having a function like this:
function updateCategory($id, $visitID,$category_name,$category_id) {
$this->profiles->update(
array(
'_id' => $id,
'visits.visitID' => $visitID,
'visits.categories.name' => $category_name,
'visits.categories.id' => $category_id,
),
array(
'$inc' => array(
'visits.categories.$.count' => 1,
'visits.categories.$.duration' =>45,
),
),
array("upsert" => true)
);
}
But with this i need to call the function for each category i will update. Is there any way to do this in one call?
EDIT:
Changed the layout a bit and made "categories" an object instead of array. Then used a combination of "category_id" and "category_name" as property name. Like:
categories: {
1_somename : {
count: 11,
duration: 122
},
1_some other name : {
count: 11,
duration: 122
},
2_yet another name : {
count: 11,
duration: 122
},
}
Then with upsert and something like
$inc: {
"visits.$.categories.1_somename.d": 100,
"visits.$.categories.2_yet another name.c": 1
}
i can update several "objects" at a time..

Answer 1

Mongodb currently not supporting arrays multiple levels deep updating (jira)
So following code will not work:
'$inc' => array(
'visits.categories.$.count' => 1,
'visits.categories.$.duration' => 123,
),
So there is some solutions around this:
1.Load document => update => save (possible concurrency issues)
2.Reorganize your documents structure like this(and update using one positional operator):
{
_id: id,
visits : [{
visitID: 12
}],
categories: [{
catagory_id: 1,
name: somename,
count: 11,
duration: 122,
visitID: 12
}]
}
}
3.Wait for multiple positional operators support (planning in 2.1 version of mongodb).
4.Reorganize your documents structure somehow else, in order to avoid multiple level arrays nesting.
