How to inject user data in $resource call? - angularjs

Question

I'm using $resource to fetch json data from a backend server.
First, I get a list of ids, with a first resource call. Then, for each id received, I use $resource to fetch data associated with this id.
Now, the problem is : I would like to associate the response with the id sent, so I can record data into a hashtable. (eg: $scope.table[response.id] = data; ). The only way I've found, is to have the API send back the id in the json response, but I'd like to associate the id with the query, so I know for which id is the response I got, without having the API to send it back.
Here is my current code (simplified, just to get the idea) :
// the factory. eg I send /rest/item/12345
app.factory('Item', function ($resource) {
return $resource("/rest/item/:id", { id: '#id'})
});
// the call (in a loop)
// I need to get { "id" : 12345, "text" : "blahblahblah" }
Item.get({ id : itemId },
function(data){
$scope.table[data.id] = data;
});
I would like to write something like this :
// the call (in a loop).
// I would like to only need to get { "text" : "blahblahblah" }
Item.get({ id : itemId },
function(id, data){
$scope.table[id] = data;
});
I guess I could use this form :
$scope.table[itemId] = Item.get({id : itemId});
But I need $scope.table[itemId] to be a "correct" value all the time, not a promise, and I want it to be updated just when I receive the answer.
Is it possible ?

Answer 1

something like this might work:
// get the array of ids
ItemIds.get({},
function(ids){
// for each id, make the request for the actual item
ids.forEach(function(id) {
Item.get({ id : id },
function(data){
// in this nested callback, you have access to data and id
$scope.table[id] = data;
});
});
});
