I've got and app that takes quote input (purity, weight, total), and it pushes to $scope.quote:

// Controller action //
$scope.quote.push({ 
  total: ((($scope.karat * $scope.spot) * $scope.percentage) / 20) * $scope.estimatedWeight,
  karat: $scope.karat * 100,
  description: $scope.description,
  actualWeight: $scope.actualWeight,
  estimatedWeight: $scope.estimatedWeight,
  percent: $scope.percentage * 100,
  spot: $scope.spot
})

and

// Factory //
app.factory('quoteFactory', function() {
  var quote = [];
  var factory = {};
  factory.getQuote = function () {
return quote;
  };
return factory;
})

and the post/save upon quote completion

$scope.save = function() {
  var now = $scope.getDate();
      $scope.quote.push({
        createdOn: $scope.getDate()
      })
    Restangular.all('quote').post($scope.quote).then(function(quote){
      $location.path('#/scrap')
    }); 
  };

When trying to access the quote JSON for list or edit I can't access all the information needed because of the JSON structure.

{
"0": {
    "total": 401.79040000000003,
    "karat": 74,
    "description": "Rings",
    "actualWeight": 12,
    "estimatedWeight": 11,
    "percent": 80,
    "spot": 1234
},
"1": {
    "total": 560.7296,
    "karat": 56.8,
    "description": "Test",
    "actualWeight": 22,
    "estimatedWeight": 20,
    "percent": 80,
    "spot": 1234
},
"2": {
    "total": 48.5625,
    "karat": 92.5,
    "description": "Testing",
    "actualWeight": 80,
    "estimatedWeight": 75,
    "percent": 70,
    "spot": 20
},
"3": {
    "createdOn": "2013-11-26T21:26:42.253Z"
},
"_id": {
    "$oid": "52951213e4b05f03172f14e7"
}
}

Each index represents a line item of the quote and the createdOn info. What I'm trying to figure out is if there is a way to be able to access all the line item information without having to call each individual index?

I've looked into some lodash/underscore, thought about restructuring the backend... Not really sure where to go from here.

How did you create the JSON? the indexes seem unnatural, if I JSON.stringify an array, it normally doesn't come with indexes included – Samuel Nov 27 '13 at 16:04
    
Or more specific; where does that JSON come from? does the server read it? I would suggest fixing the JSON, not trying to read it despite its formatting being wacky – Samuel Nov 27 '13 at 16:08
    
Perhaps since the factory is pushing into var quote = [] that is causing the indexing. But if changing to an {} for quote what method would I use to replace $scope.quote.push() – Yahtaa Nov 27 '13 at 16:27
    
But at the same time, if I lose the indexing, I would lose the ability to separate line items in a single quote offer. – Yahtaa Nov 27 '13 at 16:48

Since there is not much details available as to how your backend works or is handling the data I am assuming the problem is with generating the JSON.

What I would do is change the way Angular posts the data to the server, for example:

the Save function:

$scope.save = function() {
  var url = 'http:127.0.0.1:3000/url/you/send/your/data/to',
      json = JSON.stringify($scope.quote);

  $http({
    method: 'POST',
    url: url,
    data: json,
    headers: {
      'Content-Type': 'application/json'
    }
  }).then(function(response) {
    $location.path('#/scrap');
  });
};

This will give you more control, and will make sure you control how the data gets turned into proper JSON, in this case using the .stringify() method of the JSON object.

I see from your comments that you are concerned with indexing; conventionally objects that sync with the server have a property id that represents their database id's NOT their client array index. This is a good way to keep the model data on the client a representation of the truth on your server side.

There are quite some libraries out there that help with this process client side, I would suggest - since you are using Angular already - reading into Angular Resource.

NOTE: if you want to support older browsers with the JSON.stringify() method, make sure you use Crockford's JSON2.js

The back end is being handled by Restangular. – Yahtaa Nov 29 '13 at 14:33
