I've looked at similar questions but I can't seem to understand what I am missing. Basically, I have a service that gets data from the server, and I am trying to get that data into a controller through UI-Router's resolve property. However, after following numerous tutorials and documentations, I can't get the controller to find the data, so to speak. Everything comes up as undefined. I am hoping someone can help me understand what is happening. My code is below.
services.js
myServices.factory('SoundCloudService', ['$http', '$log', '$sce', function($http, $log, $sce) {
function getPlayerHtml() {
return $http.get('/get-site-data').then(function(oEmbed) {
return $sce.trustAsHtml(oEmbed.data.player);
});
};
function getSiteAbout() {
return $http.get('/get-site-data').then(function(oEmbed) {
return $sce.trustAsHtml(oEmbed.data.about);
});
}
function getAllTracks() {
return $http.get('/get-all-tracks').then(function(tracks) {
return JSON.parse(tracks.data);
});
};
function getAllPlaylists() {
return $http.get('/get-playlists').then(function(playlists) {
return JSON.parse(playlists.data);
})
};
function getPlaylist(pid) {
return $http.post('/get-playlist', pid, $http.defaults.headers.post).then(function(playlist) {
return playlist.data;
});
};
function getXMostTrendingFrom(x, playlist) {
var i, trending = [];
playlist.sort(function(a, b) { return b.playback_count - a.playback_count} );
for(i=0;i<x;i++) {
trending.push(all_tracks[i]);
}
return trending;
};
return {
getAllTracks: getAllTracks,
getAllPlaylists: getAllPlaylists,
getPlayerHtml: getPlayerHtml,
getSiteAbout: getSiteAbout,
getXMostTrendingFrom: getXMostTrendingFrom,
getPlaylist: getPlaylist,
};
}]);
app.js
myApp.config(['$stateProvider', '$urlRouterProvider', 'ngMetaProvider',
function($stateProvider, $urlRouterProvider, ngMetaProvider) {
$urlRouterProvider.otherwise('/');
$stateProvider
.state('main', {
url: '',
template: '<ui-view/>',
abstract:true,
controller: 'MainController',
resolve: {
player: function(SoundCloudService) { return SoundCloudService.getPlayerHtml(); },
about: function(SoundCloudService) { return SoundCloudService.getSiteAbout(); },
}
})
.state('main.home', {
url: '/',
templateUrl: '../static/partials/home.html',
controller: 'IndexController',
})
.state('main.team', {
url: '/team',
templateUrl: '../static/partials/team.html',
controller: 'TeamController',
})
.state('main.contact', {
url: '/contact',
templateUrl: '../static/partials/contact.html',
controller: 'ContactController',
})
.state('main.resources', {
url: '/resources',
templateUrl: '../static/partials/resources.html',
controller: 'ResourcesController',
})
.state('main.listen-to', {
url: '/listen-to',
templateUrl: '../static/partials/listen-to.html',
controller: 'ListenController',
})
.state('main.listen-to.season', {
url: '/listen-to/:season',
templateUrl: '../static/partials/listen-to.season.html',
controller: 'ListenController',
})
.state('main.listen-to.season.episode', {
url: '/listen-to/:season/:episode',
templateUrl: '../static/partials/listen-to.season.episode.html',
controller: 'ListenController',
})
.state('main.read', {
url: '/read',
templateUrl: '../static/partials/read.html',
controller: 'ReadController',
})
.state('main.read.post', {
url: '/read/:post',
templateUrl: '../static/partials/read.post.html',
controller: 'ReadController',
})
}
]);
controller.js
myControllers.controller('MainController', ['$scope', '$log', 'PageTitleService',
function($scope, $log, PageTitleService, player) {
$log.log(player); /* This is always undefined */
}
]);
[UPDATE]
As pointed out by Hadi in the answer below, I placed player
in the array, and the controller now looks like this:
skodenControllers.controller('MainController', ['$scope', '$log', '$sce', 'PageTitleService', 'player',
function($scope, $log, $sce, PageTitleService, player) {
$log.log(player);
}
]);
The console DOES show the data, but only after an error as such:
Error: [$injector:unpr] http://errors.angularjs.org/1.3.2/$injector/unpr?p0=playerProvider%20%3C-%20player at angular.js:38 at angular.js:3930 at Object.d [as get] (angular.js:4077) at angular.js:3935 at d (angular.js:4077) at Object.e [as invoke] (angular.js:4109) at F.instance (angular.js:8356) at angular.js:7608 at r (angular.js:347) at I (angular.js:7607)
Hopefully someone can lead me in the right direction.

As myServices and myControllers are both modules, ensure you add them as dependencies of myApp module.
// init myApp module
angular.module('myApp', ['myServices', 'myControllers']);
Edit
Some leads :
According to the documentation, when using ui-router nested views, child views (state name = main.xxx
) must declare the parent state, so you must add parent: "main"
or child views won't inherit resolved properties of main
state controller
As siteDate is loaded asynchronously in SoundCloudService (services.js:23), you cannot be sure it will be available in your controllers which are loaded at the same time.
Instead, add a getSiteDate()
method to SoundCloudService
which returns a promise. siteData is then cached and immediately return by the promise.
For example :
/**
* @name getSiteData
* @description Scrap site data
* @returns {promise} a promise
*/
function getSiteData() {
var deferred = $q.defer();
if(siteData) {
deferred.resolve(siteData);
}
else {
$http.get('/get-site-data').then(function(response) {
siteData = response.data;
deferred.resolve(siteData);
}, function(err) {
deferred.reject(err.message);
});
}
return deferred.promise;
}
SoundCloudService
to siteData
? You should simply inject SoundCloudService
in controllers that use it :For example :
skodenControllers.controller('MainController', ['$scope', '$log', '$sce', 'PageTitleService', 'SoundCloudService',
function($scope, $log, $sce, PageTitleService, SoundCloudService) {
// Note: getSiteData() could use a cache inside the service
SoundCloudService.getSiteData().then(function(siteData) {
...
});
}

You forgot pass player
into array. change to this
myControllers.controller('MainController', ['$scope', '$log',
'PageTitleService','player',
function($scope, $log, PageTitleService, player) {
$log.log(player); /* This is always undefined */
}
]);
