Retrieving data from Firebase using JavaScript to extract object details

I've been trying to understand this issue by looking at similar questions, but I'm still stuck. This is the response I get from Firebase:

'{"users":[null,{"-JFhOFSUwhk3Vt2-KmD1": {"color":"White","model":"650i","year":"2014","make":"BMW"}, "-JGW6vwYtnfoIxeQlwCq": {"color":"Red","model":"AMG","year":"2014","make":"Mercedes"}},{"-JFhNnaAq1rr_SHzJcIr":{"color":"Red","model":"F150 FX4","year":"2014","make":"Ford"}},{"-JFhYXNpUG3wSMcfB3Uz":{"color":"Blue","model":"AMG","year":"2014","make":"Mercedes"}},null,null,null,{"- JFly1lt6UWj-r2985ed":{"color":"red","model":"650i","year":"2014","make":"bmw"}}]}'

These cars belong to 2 different users and I want to display the information in a table. How can I utilize parse to achieve this? Here's what the call looks like:

$scope.read = function () {
    $http.get(BaseUrl + ".json").success(function (data) {
        $scope.AllCars = data
    });
}

Currently, I can log in with each user and display the cars they have entered on a table using Angular. Every time they add a car, it creates a new row. My goal is for any user to see their cars as well as others. I aim to fetch this data and populate a separate table. Since the data will be constantly changing, I assume I need to handle potential updates in the code.

This is my Firebase data:

 users
 1
 -JFhOFSUwhk3Vt2-KmD1
 color: "White"
 make: "BMW"
 model: "650i"
 year: "2014
 -JGW6vwYtnfoIxeQlwCq
 color: "Red"
 make: "Mercedes"
 model: "AMG"
 year: "2014"
 2
 -JFhNnaAq1rr_SHzJcIr
 color: "Red"
 make: "Ford"
 model: "F150 FX4"
 year: "2014"
 3
 -JFhYXNpUG3wSMcfB3Uz
 color: "Blue"
 make: "Mercedes"
 model: "AMG"
 year: "2014"
 7

Answer №1

To consolidate all the cars into a single object, you can use the following code:

var allCars = {};
data.users.filter(Boolean).forEach(function(user){
  Object.keys(user).map(function(key){ allCars[key] = this[key]; }, user);
});

console.log(allCars);

This code will output something similar to:

Object {-JFhOFSUwhk3Vt2-KmD1: Object, -JGW6vwYtnfoIxeQlwCq: Object, -JFhNnaAq1rr_SHzJcIr: Object, -JFhYXNpUG3wSMcfB3Uz: Object, -JFly1lt6UWj-r2985ed: Object…}
