Is it possible to simultaneously use two $scoped variables within an Angular controller?

Currently, I am developing an angular application that connects to a Rails backend and interacts with the database through API calls to receive JSON objects. My challenge lies in defining multiple scoped variables within a controller. At the moment, I have a variable called markets which holds all market data from the database - essentially serving as the index. However, I am facing difficulty accessing a single market for the show page. Initially, I had two separate controllers, but it didn't feel like the right approach.

Any help or guidance on this issue would be greatly appreciated!

Listed below are the routes:

angular.module('farmCart', ['ui.router', 'templates'])
.config([
  '$stateProvider',
  '$urlRouterProvider',
  function($stateProvider, $urlRouterProvider) {
    // Route configurations 
  },
]);

A snippet from the Markets Factory:

angular.module('farmCart')
.factory('markets', [
  '$http',
  function($http) {
    // Factoring logic for fetching markets
  },
]);

Snippet from the Markets Controller:

angular.module('farmCart')
.controller('marketsCtrl', [
  '$scope',
  'markets',
  function($scope, markets) {
    // Controller logic for handling markets 
  },
]);

Answer №1

Your variables are referred to as marketsPromise and market, however, you have not injected them into your controller. It might be helpful to create separate controllers for each state as they seem to serve different purposes.

angular.module('farmCart')
.controller('marketsCtrl', [
  '$scope',
  'marketsPromise',
  function($scope, marketsPromise) {
    $scope.markets = marketsPromise;
  },
]);

angular.module('farmCart')
.controller('marketCtrl', [
  '$scope',
  'market',
  function($scope, market) {
    $scope.market = market;
  },
]);

Additionally, it could be beneficial to reconsider the name of the marketsPromise resolve since ui-router injects the data itself, not the promise, which may cause confusion.
