How can I have two $scoped variables in an Angular controller?

Question

I'm creating an angular app with a rails backend and accessing the database through api calls and receiving a json object. I'm having trouble with defining multiple scoped variables within a controller. I'm currently returning a variable markets which contains all markets in the database - this is my index. I'm also trying to access a single market for the show page and this is where I'm having trouble. Initially I had 2 separate controllers which worked but didn't seem correct.

Thanks!

Routes:

angular.module('farmCart', ['ui.router', 'templates'])
.config([
  '$stateProvider',
  '$urlRouterProvider',
  function($stateProvider, $urlRouterProvider) {
    $stateProvider
      .state('home', {
        url: '/home',
        templateUrl: 'home/_home.html',
        controller: 'mainCtrl',
      })
      .state('markets', {
        url: '/markets',
        templateUrl: 'markets/_markets.html',
        controller: 'marketsCtrl',
        resolve: {
          marketsPromise: ['markets', function(markets) {
            return markets.getAll();
          },
          ],
        },
      })
      .state('market', {
        url: '/markets/{id}',
        templateUrl: 'markets/_market.html',
        controller: 'marketsCtrl',
        resolve: {
          market: ['$stateParams', 'markets', function($stateParams, markets) {
            return markets.get($stateParams.id);
          },
          ],
        },
      })
      .state('booths', {
        url: '/booths/{id}',
        templateUrl: 'booths/_booths.html',
        controller: 'boothsCtrl',
        resolve: {
          booth: ['$stateParams', 'booths', function($stateParams, booths) {
            return booths.get($stateParams.id);
          },
          ],
        },
      });
    $urlRouterProvider.otherwise('home');
  },
]);

Markets Factory:

angular.module('farmCart')
.factory('markets', [
  '$http',
  function($http) {
    var o = {
      markets: [],
    };

    o.getAll = function() {
      return $http.get('/markets.json').success(function(data) {
        angular.copy(data, o.markets);
      });
    };

    o.get = function(id) {
      return $http.get('/markets/' + id + '.json').then(function(res) {
        return res.data;
      });
    };

    return o;
  },
]);

Markets Controller:

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

Answer 1

Your resolves are named marketsPromise and market , none of which you're actually injecting into your controller. I'd recommend you use two controllers since it seems like the two states have separate 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;
  },
]);

Also, you may want to reconsider the name of the marketsPromise resolve, because ui-router will inject the data itself, not the promise, which may lead to confusion.
