Displaying nested JSON with angularjs - json

Question

I am trying to display nested JSON in a page. I'm not sure how to drill down into it.
In my app js file I have an parameter called initialData that I want to call a function getProducts() when the view is called...
'use strict';
var quoteApp = angular.module('quoteApp', ['ui.router']);
quoteApp.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/home');
$stateProvider
// HOME STATES AND NESTED VIEWS ========================================
.state('home', {
url: '/home',
templateUrl: 'ng-views/choose.html',
controller: "quoteBuilderController",
resolve: {
initialData: ['quoteApi', function (quoteApi) {
return quoteApi.getProducts();
}]
}
})
});
my quoteApi looks like this in case you want to see it...
(function () {
'use strict';
angular.module('quoteApp').factory('quoteApi', quoteApi);
quoteApi.$inject = ['$http'];
function quoteApi($http) {
var service = {
getProducts: getProducts,
getPrices: getPrices
};
var baseUrl = 'http://www.website.com/api/Pricing';
return service;
function getProducts() {
return httpGet('/GetProductCatalogue');
}
function getPrices() {
return httpGet('/GetPrices');
}
/** Private Methods **/
function httpExecute(requestUrl, method, data){
return $http({
url: baseUrl + requestUrl,
method: method,
data: data,
headers: requestConfig.headers }).then(function(response){
return response.data;
});
}
function httpGet(url){
return httpExecute(url, 'GET');
}
}
})();
So quoteApi.getProducts() returns JSON that looks like this...
{
"Cat1": [
{
"product_id": 1,
"product_name": "Prod1"
},
{
"product_id": 2,
"product_name": "Prod2"
}
],
"Cat2": [
{
...
}
]
}
My controller for the view looks like this...
(function () {
'use strict';
angular.module('quoteApp').controller('quoteController', ['$scope', '$http', '$timeout', quoteController]);
quoteController.$inject = ['initialData', 'quoteApi'];
function quoteController($scope, initialData) {
$scope.cat1Products = initialData;
};
})();
So my question is, how can I get 'initialData' to load products from Cat1 only? Should I try to do this from the html? It seems like it should be straight forward enough but I can seem to get it. Thank you.

Answer 1

You need to transform your response from your http request further so you only return the piece you require, and you may also want to consider using the .then() approach:
$http.get('/someUrl').then(function(response) {
//Do something with response.data.Cat1 here
}, function(errResponse) {
console.error('Error while fetching data');
});

Answer 2

Just take out cat1 from your initialData object
function quoteController($scope, initialData) {
$scope.cat1Products = initialData['Cat1'];
};
