How to send array of object

Hi, i have tried these two methods below but i still can’t get it done, it always send array of object as a string instead of array of object. may i know is there any possible solution for this problem?

Method#1

  var data  = $scope.dealsData;
  Upload.upload({
                  url: '/api/postDeals',
                  fields:data,
                  data:{favour:$scope.choices},
                  file: file
              }

in my nodejs console

{ deals_name: 'ad',
  deals_price: '12.12',
  deals_amount: '12',
  deals_description: 'asd',
  deals_term_condition: 'asd',
  favour_type: 'survey',
  data: '{"favour":[{"type":"mcq","$$hashKey":"object:67","mcq_question":"asd","mcq_choice1":"asd","mcq_choice2":"asd"},{"type":"open_ended","$$hashKey":"object:68","open_ended_question":"asd"}]}' }

if i do it the usual way i don’t have the $$hashkey or object:6x thingy in my json Method#2

$scope.dealsData.favour =  angular.toJson($scope.choices);
var data  = $scope.dealsData;
  Upload.upload({
                  url: '/api/postDeals',
                  fields:data,
                  file: file
              }

in my nodejs console

{ deals_name: 'asd',
  deals_price: '12.12',
  deals_amount: '12',
  deals_description: 'asd',
  deals_term_condition: 'asd',
  favour_type: 'survey',
  favour: '[{"type":"mcq","mcq_question":"asd","mcq_choice1":"asd","mcq_choice2":"asd"},{"type":"open_ended","open_ended_question":"asd"}]' }

Just had the same issue. As per the docs using arrayKey: ‘[]’ solved the issue for me e.g. Upload.upload({ data: val, arrayKey: '[]' })

Cases:

Case 1: when fields is object,

var val = { "name": 'kuldeep Aggarwal' }
Upload.upload({
  fields: val
})

then the code is send correct params: {fields: {"name": "Kuldeep Aggarwal"}}

Case 2: when fields is array:

var val = [{"name": "kuldeep Aggarwal"}]
Upload.upload({
  fields: val
})

then the code send incorrect params => {fields: {"0": { "name": "Kuldeep Aggarwal" }}}

instead it should send params => {fields: [{"name": "Kuldeep Aggarwal"}] }

So, if you think my assumption is right then I would like to contribute and create a PR for this issue.
