How to call $resource custom method in controller

I have a factory:
myService:
'use strict';
app.factory('myService', ['$resource', 'ngAuthSettings', function ($resource, ngAuthSettings) {
var serviceBase = ngAuthSettings.apiServiceBaseUri;
return $resource(serviceBase + 'api/category/', {}, {
update: {
method: 'PUT'
},
getAllByCategory: {
url: serviceBase + 'api/category/GetAllByCategory',
method: 'GET', isArray: true
}
});
}]);
Then I have a controller:
searchController:
'use strict';
app.controller('searchController',
['ngAuthSettings', '$scope', 'myService', '$routeParams', '$location',
function (ngAuthSettings, $scope, myService, $routeParams, $location) {
function init() {
var search = $location.search();
var keywords = search.keywords;
var model = myService.getAllByCategory({ categoryId: 2, page: $routeParams.page });
$scope.categoryAds = model.ads;
$scope.bigTotalItems = model.totalCount;
$scope.maxSize = ngAuthSettings.maxPagingSize;
}
init();
}]);
Why my model.ads is always undefined? Isn't this the right way to call $resource custom method in controller?

As response may take some time but you are adding assignment very immediatly hence it happening put it in promise/action after resource,
'use strict';
app.controller('searchController', ['ngAuthSettings', '$scope', 'myService', '$routeParams', '$location',
function (ngAuthSettings, $scope, myService, $routeParams, $location) {
function init() {
var search = $location.search();
var keywords = search.keywords;
var model = myService.getAllByCategory({ categoryId: 2, page: $routeParams.page },
function() {
$scope.categoryAds = model.ads;
$scope.bigTotalItems = model.totalCount;
$scope.maxSize = ngAuthSettings.maxPagingSize;
}
);
}
init();
}
]);

$state.go doesn't work with ng-click

When an item is clicked, its path is sent as parameter to state function and the state function does $state.go to load a state with the passed path as parameter.
This doesn't seem to work. What am I missing here?
Template
<div ng-click="state(item.class, item.path, item.mime_type)">
Controller
controller("groupsListCtrl", ["$scope", "handler", "$state",
function($scope, handler, $state) {
handler.get("/home").then(function(response) {
$scope.data = response;
$scope.items = $scope.data.inventory;
$scope.state = function(stateType, objectPath, mimeType) {
$state.go("workarea.user", {
path: objectPath
});
}
})
}
])
Router
.state("workarea.user", {
url: "^/workarea/:path",
requireLogin: true,
views: {
"options": {
templateUrl: "/views/options.html",
controller: "optionsCtrl"
},
"workspace": {
templateUrl: "/views/workspace.html",
controller: "workspaceCtrl"
},
"comments": {
templateUrl: "/views/comments.html",
controller: "commentsCtrl"
}
}
});

handler.get("/home").then(function(response) { looks like a promise to me.
Try moving $scope.state definition outside this promise.
controller("groupsListCtrl", ["$scope", "handler", "$state",
function($scope, handler, $state) {
handler.get("/home").then(function(response) {
$scope.data = response;
$scope.items = $scope.data.inventory;
});
$scope.state = function(stateType, objectPath, mimeType) {
$state.go("workarea.user", {
path: objectPath
});
}
}
])

Advice on workflow for an 8 step application with ANGULAR.js

I'm creating an application with Angular.js and I'm getting a bit confused of how to use Angular to make it.
Below, you can see a preview of what I have for the moment, it's ugly but it works.
I just feel like there is much better ways of doing this, and would like to get other user inputs, knowing this :
The application will:
1) collect inputs over 8 steps
2) dependeing of those inputs, display specific results.
3) Being able to go to any state at any moment
// Create an application module
var app = angular.module('website', ['ngSanitize','ngAnimate','ui.router']);
app.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise("/home");
$stateProvider
.state('home', {
url: "/home",
templateUrl: "js/partials/home.html",
controller: HomeCtrl
})
.state('step1', {
url: "/step1",
templateUrl: "js/partials/step1.html",
controller: Step1Ctrl
})
.state('step2', {
url: "/step2",
templateUrl: "js/partials/step2.html",
controller: Step2Ctrl
})
.state('step3', {
url: "/step3",
templateUrl: "js/partials/step3.html",
controller: Step3Ctrl
})
.state('step4', {
url: "/step4",
templateUrl: "js/partials/step4.html",
controller: Step4Ctrl
})
.state('step5', {
url: "/step5",
templateUrl: "js/partials/step5.html",
controller: Step5Ctrl
})
.state('step6', {
url: "/step6",
templateUrl: "js/partials/step6.html",
controller: Step6Ctrl
});
});
function getNewPercentageValue(step,percent){
var NewPercentage = 0;
if(percent){
NewPercentage = percent * step;
}else{
$rootScope.values.ActualPercentage = (100/8);

}
return NewPercentage;
}
function HomeCtrl($scope, $http, $rootScope, $state) {

$rootScope.values = {
ActualPercentageSteps: (100/8),
ActualPercentage: 0
};
}
function Step1Ctrl($scope, $http, $rootScope, $state) {
$rootScope.values.ActualPercentage = getNewPercentageValue(1,$rootScope.values.ActualPercentageSteps);
$scope.services = [
{name: 'Service 1', id: 1},
{name: 'Service 2', id: 2},

}
function Step7Ctrl($scope, $http, $rootScope, $state) {
}

You can define your controllers using app.controller("MyCtrl", function($scope){}) and then don't need to have all the globally defined functions (just reference them using a quoted string like controller:"MyCtrl").
Aside from that you can move your common data into a service or factory since both end up being singletons and will persist the data throughout the lifetime of the application, here's a plunk showing an example:
http://plnkr.co/edit/4OYWi35Ke2GGDB6wY2W9
main thing to note here is use of angular.copy when attempting to replace the entire object instead of just using = since both controllers are just pointing to the same referenced object so I don't ever want to create a new object and point the service at that or things would get disconnected.
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope, Service) {
$scope.items = Service.items;
$scope.someModel = {};
$scope.addItem = function(item){
Service.addItem(item);
}
$scope.resetItems = function(){
Service.resetItems();
}
});
app.controller('AnotherCtrl', function($scope, Service) {
$scope.items = Service.items;
});
app.service('Service', function($timeout){
var someService = {
items:[],
id:0,
addItem:function(item){
someService.items.push({label:item, id:someService.id++});
},
resetItems:function(){
someService.id=0;
//simulated HTTP call
$timeout(function(){
angular.copy([], someService.items);
})
}
};
return someService;
})

Dynamic injection angularjs?

i am using one of the basic concept of angularjs that child controller inherit from parent controller. so i have writen the following code :
var editChannelCtrl = function ($scope, $route, $location, youtube) {
$scope.loading = false;
$scope.saved = false;
$scope.errors = [];
if (angular.isDefined($route.current.params.id)) {
$scope.isOldChannel = true;
$scope.isNewChannel = false;
} else {
$scope.isNewChannel = true;
$scope.isOldChannel = false;
}
};
editChannelCtrl.$inject = ['$scope', '$route', '$location', 'youtube'];
editChannelCtrl.resolve = {
channel: ['ServiceChannel' , function (ServiceChannel) {
return ServiceChannel.ChannelLoader();
}]
};
var oldChannelCtrl = function ($scope, $location, channel) {
$scope.channel = channel;
};
oldChannelCtrl.$inject = ['$scope' , '$location', 'channel'];
var newChannelCtrl = function ($scope, $location, Channel) {
$scope.channel = {
id: null,
version: 1
};
};
newChannelCtrl.$inject = ['$scope' , '$location', 'Channel'];
and for routes what i do , that i resolve the channel that load the channel for the edit form with the following code.
.when('/admin/refactor/channel/edit/:id', {
controller: editChannelCtrl,
templateUrl: '/admin/assets/views/channelForm.html',
resolve: editChannelCtrl.resolve
})
.when('/admin/refactor/channel/new', {
controller: editChannelCtrl,
templateUrl: '/admin/assets/views/channelForm.html'
})
but i don't know why angularjs don't figure how to inject channel to oldChannelCtrl ?

AngularJS ui-router $state.go('^') only changing URL in address bar, but not loading controller

I am trying to create a "Todo App" with angularjs ui-router. It has 2 columns:
Column 1: list of Todos
Column 2: Todo details or Todo edit form
In the Edit and Create controller after saving the Todo I would like to reload the list to show the appropriate changes. The problem: after calling $state.go('^') when the Todo is created or updated, the URL in the browser changes back to /api/todo, but the ListCtrl is not executed, i.e. $scope.search is not called, hence the Todo list (with the changed items) is not retrieved, nor are the details of the first Todo displayed in Column 2 (instead, it goes blank).
I have even tried $state.go('^', $stateParams, { reload: true, inherit: false, notify: false });, no luck.
How can I do a state transition so the controller eventually gets executed?
Source:
var TodoApp = angular.module('TodoApp', ['ngResource', 'ui.router'])
.config(function ($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/api/todo');
$stateProvider
.state('todo', {
url: '/api/todo',
controller: 'ListCtrl',
templateUrl: '/_todo_list.html'
})
.state('todo.details', {
url: '/{id:[0-9]*}',
views: {
'detailsColumn': {
controller: 'DetailsCtrl',
templateUrl: '/_todo_details.html'
}
}
})
.state('todo.edit', {
url: '/edit/:id',
views: {
'detailsColumn': {
controller: 'EditCtrl',
templateUrl: '/_todo_edit.html'
}
}
})
.state('todo.new', {
url: '/new',
views: {
'detailsColumn': {
controller: 'CreateCtrl',
templateUrl: '/_todo_edit.html'
}
}
})
;
})
;
TodoApp.factory('Todos', function ($resource) {
return $resource('/api/todo/:id', { id: '#id' }, { update: { method: 'PUT' } });
});
var ListCtrl = function ($scope, $state, Todos) {
$scope.todos = [];
$scope.search = function () {
Todos.query(function (data) {
$scope.todos = $scope.todos.concat(data);
$state.go('todo.details', { id: $scope.todos[0].Id });
});
};
$scope.search();
};
var DetailsCtrl = function ($scope, $stateParams, Todos) {
$scope.todo = Todos.get({ id: $stateParams.id });
};
var EditCtrl = function ($scope, $stateParams, $state, Todos) {
$scope.action = 'Edit';
var id = $stateParams.id;
$scope.todo = Todos.get({ id: id });
$scope.save = function () {
Todos.update({ id: id }, $scope.todo, function () {
$state.go('^', $stateParams, { reload: true, inherit: false, notify: false });
});
};
};
var CreateCtrl = function ($scope, $stateParams, $state, Todos) {
$scope.action = 'Create';
$scope.save = function () {
Todos.save($scope.todo, function () {
$state.go('^');
});
};
};

I would give an example (a draft) of HOW TO nest edit into detail. Well, firstly let's amend the templates.
The Detail template, contains full definition of the detail. Plus it now contains the attribute ui-view="editView". This will assure, that the edit, will "replace" the detail from the visibility perspective - while the edit scope will inherit all the detail settings. That's the power of ui-router
<section ui-view="editView">
<!-- ... here the full description of the detail ... -->
</section>
So, secondly let's move the edit state, into the detail
// keep detail definition as it is
.state('todo.details', {
url: '/{id:[0-9]*}',
views: {
'detailsColumn': {
controller: 'DetailsCtrl',
templateUrl: '/_todo_details.html'
}
}
})
// brand new definition of the Edit
.state('todo.details.edit', { // i.e.: url for detail like /todo/details/1/edit
url: '/edit',
views: {
'editView': { // inject into the parent/detail view
controller: 'EditCtrl',
templateUrl: '/_todo_edit.html'
}
}
})
Having this adjusted state and template mapping, we do have a lot. Now we can profit from the ui-router in a full power.
We'll define some methods on a DetailCtrl (remember, to be available on the inherit Edit state)
var DetailsCtrl = function ($scope, $stateParams, Todos) {
$scope.id = $stateParams.id // keep it here
// model will keep the item (todos) and a copy for rollback
$scope.model = {
todos : {},
original : {},
}
// declare the Load() method
$scope.load = function() {
Todos
.get({ id: $stateParams.id })
.then(function(response){
// item loaded, and its backup copy created
$scope.model.todos = response.data;
$scope.model.original = angular.copy($scope.model.todos);
});
};
// also explicitly load, but just once,
// not auto-triggered when returning back from Edit-child
$scope.load()
};
OK, it should be clear now, that we do have a model with the item model.todos and its backup model.original.
The Edit controller could have two actions: Save() and Cancel()
var EditCtrl = function ($scope, $stateParams, $state, Todos) {
$scope.action = 'Edit';
// ATTENTION, no declaration of these,
// we inherited them from parent view !
//$scope.id .. // we DO have them
//$scope.model ...
// the save, then force reload, and return to detail
$scope.save = function () {
Todos
.update({ id: id })
.then(function(response){
// Success
$scope.load();
$state.go('^');
},
function(reason){
// Error
// TODO
});
};
// a nice and quick how to rollback
$scope.cancel = function () {
$scope.model.todos = Angular.copy($scope.model.original);
$state.go('^');
};
};
That should give some idea, how to navigate between parent/child states and forcing reload.
NOTE in fact, instead of Angular.copy() I am using lo-dash _.cloneDeep() but both should work

Huge thanks for Radim Köhler for pointing out that $scope is inherited. With 2 small changes I managed to solve this. See below code, I commented where I added the extra lines. Now it works like a charm.
var TodoApp = angular.module('TodoApp', ['ngResource', 'ui.router'])
.config(function ($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/api/todo');
$stateProvider
.state('todo', {
url: '/api/todo',
controller: 'ListCtrl',
templateUrl: '/_todo_list.html'
})
.state('todo.details', {
url: '/{id:[0-9]*}',
views: {
'detailsColumn': {
controller: 'DetailsCtrl',
templateUrl: '/_todo_details.html'
}
}
})
.state('todo.edit', {
url: '/edit/:id',
views: {
'detailsColumn': {
controller: 'EditCtrl',
templateUrl: '/_todo_edit.html'
}
}
})
.state('todo.new', {
url: '/new',
views: {
'detailsColumn': {
controller: 'CreateCtrl',
templateUrl: '/_todo_edit.html'
}
}
})
;
})
;
TodoApp.factory('Todos', function ($resource) {
return $resource('/api/todo/:id', { id: '#id' }, { update: { method: 'PUT' } });
});
var ListCtrl = function ($scope, $state, Todos) {
$scope.todos = [];
$scope.search = function () {
Todos.query(function (data) {
$scope.todos = $scope.todos(data); // No concat, just overwrite
if (0 < $scope.todos.length) { // Added this as well to avoid overindexing if no Todo is present
$state.go('todo.details', { id: $scope.todos[0].Id });
}
});
};
$scope.search();
};
var DetailsCtrl = function ($scope, $stateParams, Todos) {
$scope.todo = Todos.get({ id: $stateParams.id });
};
var EditCtrl = function ($scope, $stateParams, $state, Todos) {
$scope.action = 'Edit';
var id = $stateParams.id;
$scope.todo = Todos.get({ id: id });
$scope.save = function () {
Todos.update({ id: id }, $scope.todo, function () {
$scope.search(); // Added this line
//$state.go('^'); // As $scope.search() changes the state, this is not even needed.
});
};
};
var CreateCtrl = function ($scope, $stateParams, $state, Todos) {
$scope.action = 'Create';
$scope.save = function () {
Todos.save($scope.todo, function () {
$scope.search(); // Added this line
//$state.go('^'); // As $scope.search() changes the state, this is not even needed.
});
};
};

I might have faced a similar problem the approach i took was to use $location.path(data.path).search(data.search); to redirect the page then in the controller I caught the $locationChangeSuccess event. I other words I use the $location.path(...).search(...) as apposed to $state.go(...) then caught the $locationChangeSuccess event which will be fired when the location changes occurs before the route is matched and the controller invoked.
var TodoApp = angular.module('TodoApp', ['ngResource', 'ui.router'])
.config(function ($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/api/todo');
$stateProvider
.state('todo', {
url: '/api/todo',
controller: 'ListCtrl',
templateUrl: '/_todo_list.html'
})
.state('todo.details', {
url: '/{id:[0-9]*}',
views: {
'detailsColumn': {
controller: 'DetailsCtrl',
templateUrl: '/_todo_details.html'
}
}
})
.state('todo.edit', {
url: '/edit/:id',
views: {
'detailsColumn': {
controller: 'EditCtrl',
templateUrl: '/_todo_edit.html'
}
}
})
.state('todo.new', {
url: '/new',
views: {
'detailsColumn': {
controller: 'CreateCtrl',
templateUrl: '/_todo_edit.html'
}
}
})
;
})
;
TodoApp.factory('Todos', function ($resource) {
return $resource('/api/todo/:id', { id: '#id' }, { update: { method: 'PUT' } });
});
var ListCtrl = function ($scope, $state, Todos, todo.details) {
/*here is where i would make the change*/
$scope.$on('$locationChangeSuccess', function () {
$scope.search();
$route.reload();
});
$scope.todos = [];
$scope.search = function () {
Todos.query(function (data) {
$scope.todos = $scope.todos.concat(data);
});
};
$scope.search();
};
var DetailsCtrl = function ($scope, $stateParams, Todos) {
$scope.todo = Todos.get({ id: $stateParams.id });
};
var EditCtrl = function ($scope, $stateParams, $state, Todos, $location) {
$scope.action = 'Edit';
var id = $stateParams.id;
$scope.todo = Todos.get({ id: id });
$scope.save = function () {
Todos.update({ id: id }, $scope.todo, function () {
//here is where I would make a change
$location.path('todo.details').search($stateParams);
});
};
};
var CreateCtrl = function ($scope, $stateParams, $state, Todos, $location) {
$scope.action = 'Create';
$scope.save = function () {
Todos.save($scope.todo, function () {
//here is where I would make a change
$location.path('todo.details');
});
};
};
the $locationChangeSuccess event occurs before the route is matched and the controller invoked
