I am trying to route my page to another page once the controller is accessed but its not working. I can route the first two pages but the third one is not working. Can someone help me on this.
This is my routing code:
$routeProvider', function ($routeProvider) {
$routeProvider.
when('/category', {
//templateUrl : 'js/partials/course-list.html',
controller : 'CategoryController'
}).
when('/category/:categoryid', {
templateUrl : 'js/partials/film-list.html',
controller : 'MovieController'
}).
when('/actor/:filmid', {
templateUrl : 'js/partials/actor-list.html',
controller : 'ActorController'
}).
otherwise({
redirectTo : '/'
});
}
Currently my ActorController is not working. Once i click on the movies it should show the actor of the films but in my case its not working
This is my partial html file for the movie-list.html
<section>
<h3>{{movieCount}}</h3>
<table>
<tr data-ng-repeat="movie in movies" data-ng-click="selectFilm($event,movie)" style="cursor: pointer;">
<td>{{movie.title}}</td>
</tr>
<strong>{{successMessage}}</strong>
</table>
And this is my controller code
).controller('ActorController',
[
'$scope',
'dataService',
'$routeParams',
function ($scope, dataService, $routeParams){
$scope.actors = [ ];
$scope.actorCount = 0;
var getActors = function (moviecode) {
dataService.getActors(moviecode).then(
function (response) {
$scope.actorCount = response.rowCount + ' actors';
$scope.actors = response.data;
$scope.showSuccessMessage = true;
$scope.successMessage = "Actor Success";
},
function (err){
$scope.status = 'Unable to load data ' + err;
}
); // end of getStudents().then
};
// only if there has been a courseid passed in do we bother trying to get the students
if ($routeParams && $routeParams.filmid) {
console.log($routeParams.filmid);
getActors($routeParams.filmid);
}
}
]
)
This is the selectFilm() code from the MovieController
$scope.selectedFilm = {};
$scope.selectFilm = function ($event,movie) {
$scope.selectedFilm = movie;
$location.path('/actor/' + movie.film_id);
}
This is the movie controller code
).controller('MovieController',
[
'$scope',
'dataService',
'$routeParams',
'$location',
function ($scope, dataService, $routeParams, $location){
$scope.movies = [ ];
$scope.movieCount = 0;
var getMovies = function (moviecode) {
dataService.getMovies(moviecode).then(
function (response) {
$scope.movieCount = response.rowCount + ' movies';
$scope.movies = response.data;
$scope.showSuccessMessage = true;
$scope.successMessage = "Movies Success";
},
function (err){
$scope.status = 'Unable to load data ' + err;
}
); // end of getStudents().then
};
$scope.selectedFilm = {};
$scope.selectFilm = function ($event,movie) {
$scope.selectedFilm = movie;
$location.path('/actor/' + movie.film_id);
// $window.location.href = '/actor/' + movie.film_id
console.log(movie.film_id);
}
// only if there has been a courseid passed in do we bother trying to get the students
if ($routeParams && $routeParams.categoryid) {
console.log($routeParams.categoryid);
getMovies($routeParams.categoryid);
}
}
]
)
I solved the problem by myself wher first of all the $location variable was not defined in the function and later on the movie object dont have the film_id so I had to readjust my SQL query to make it work. After changing the SQL query i can route my page now.

I have a page where I display all usernames. Now I want to click on one of these usernames make a call to server to retrieve more information and display it on separate User page. (First name, last name, etc)
My problem is that when I click on username page opens but fields are not populated. Could you please review my code and suggest what I am doing wrong there?
app.config(function($routeProvider) {
$routeProvider
.when("/", {
templateUrl : "pages/login_page.html"
})
.when("/userpage", {
controller : 'UserController',
templateUrl : "pages/user_page.html"
})
.when("/allusers", {
controller : 'AllUserController',
templateUrl : "pages/all_users.html"
});
});
This is my login code. After user authenticated it can see all other users. So I am changing view to #allusers
app.directive("loginForm", function (AuthorizedHttp, ConfigurationRepository, UserObj) {
return {
restrict: 'E',
scope: {
},
templateUrl: 'templates/login-template.html',
replace: 'true',
controller: ['$scope', '$http', '$window',
function($scope, $location, $window) {
$scope.loginError = false;
$scope.login = function () {
$scope.loginError = false;
UserObj.setState(null, null, $scope.username, $scope.password, null);
AuthorizedHttp.get('http://{0}/account/user/login'.format(ConfigurationRepository.getBackendHostName()))
.success(function (response) {
UserObj.setState(response.first_name, response.last_name, response.email, $scope.password, response.role, response.timezones);
$window.location = "#allusers";
})
.error(function (err, status) {
$scope.username = '';
$scope.password = '';
$scope.loginError = true;
})
}
}
]
}
});
Code below responsible to make a call and retrieve all users. Works fine.
app.controller('AllUserController', function ($scope, AuthorizedHttp, ConfigurationRepository, UserObj, UserCurrent, TimezoneService) {
$scope.init = function () {
TimezoneService.getAllUsers()
.success(function (response) {
$scope.users_emails = response.map(function (item) {return item.email})
})
.error(function (err, status) {
alert('Error loading all users ')
});
};
});
HTML to display all usernames. Also set ng-click to pass a username as parameter to retrieve required user.
<div ng-controller="AllUserController" ng-init="init()">
<div ng-controller="UserController">
<div ng-repeat="email in users_emails" class="item-unchecked">
<a ng-click="getUser(email)">{{email}}</a>
</div>
</div>
</div>
User controller. Executed every time I click on username link.
app.controller('UserController', function ($scope, AuthorizedHttp, ConfigurationRepository, UserObj, UserCurrent, TimezoneService, $window) {
$scope.user_display_name = 'Now set yet';
$scope.getUser = function(username) {
TimezoneService.getUser(username)
.then(function (response) {
$scope.required_user = response.data;
$scope.user_display_name = '{0} ({1})'.format(response.data.first_name, response.data.email);
$scope.user_timezones = response.data.timezones.map(function (item) {
return item.timezone_name
});
$scope.user_role = response.data.role;
$window.location = '#userpage';
});
};
});
As a result user_page.html is loaded but all fields are not set. I don't understand why since I am setting a scope value before I change a $window.location.
Remove ng-controller="UserController" from your HTML
Create a function in your AllUserController like that
$scope.customNavigate = function(routeToNavigate, routeParameter){
$location.path("/" + routeToNavigate + "/" + routeParameter);
}
Change .when("/userpage", { to .when("/userpage/:email", {
Change ng-click="getUser(email)" to ng-click="customNavigate("userpage", email)"
Inject $routeParams to your UserController
Change $scope.getUser = function(username) { to function getUser (username) {
Call getUser($routeParams.email) in your UserController.
I have this in the controller
angular.module('myApp')
.controller('TaskController', function ($scope, TaskFactory) {
$scope.addTodo = function () {
$scope.todos.push({text : $scope.formTodoText});
$scope.formTodoText = '';
};
});
and this in the factory
angular.module('myApp')
.factory('TaskFactory', function ($q, $http) {
var sendTasks = function(params) {
var defer = $q.defer();
console.log(1, params);
$http.post('http://localhost:3000/task/save', params)
.success(function(data) {
console.log(2);
console.log('data', data);
})
.error(function(err) {
defer.reject(err);
});
return defer.promise;
}
return {
sendTask: function(taskData) {
console.log('taskData', taskData);
return sendTasks('/task/save', {
taskData : taskData
})
}
}
});
all I need is to know, how to send the data from the controller to the factory in order to do the POST to the specified route ?
You just need to call the function/method inside factory with the required params.
angular.module('myApp')
.controller('TaskController', function ($scope, TaskFactory) {
$scope.addTodo = function () {
$scope.todos.push({text : $scope.formTodoText});
TaskFactory.sendTask({data : $scope.formTodoText})
$scope.formTodoText = '';
};
});
You can follow Dan Wahlin blog post.
Controller:
angular.module('customersApp')
.controller('customersController', ['$scope', 'dataFactory', function ($scope, dataFactory) {
$scope.status;
dataFactory.updateCustomer(cust)
.success(function () {
$scope.status = 'Updated Customer! Refreshing customer list.';
})
.error(function (error) {
$scope.status = 'Unable to update customer: ' + error.message;
});
}
Factory:
angular.module('customersApp')
.factory('dataFactory', ['$http', function($http) {
var urlBase = '/api/customers';
dataFactory.updateCustomer = function (cust) {
return $http.put(urlBase + '/' + cust.ID, cust)
};
}
Hope that solve your problem.
You can call the function directly on the TaskFactory that you pass into the controller as a dependency.
I've cleaned up your code a bit and created a plunk for you here:
And here's the code:
Controller
(function(angular) {
// Initialise our app
angular.module('myApp', [])
.controller('TaskController', function($scope, TaskFactory) {
// Initialise our variables
$scope.todos = [];
$scope.formTodoText = '';
$scope.addTodo = function() {
// Add an object to our array with a 'text' property
$scope.todos.push({
text: $scope.formTodoText
});
// Clear the input
$scope.formTodoText = '';
// Call function to send all tasks to our endpoint
$scope.sendTodos = function(){
TaskFactory.sendTasks($scope.todos);
}
};
});
})(angular);
Factory
(function(angular) {
angular.module('myApp')
.factory('TaskFactory', function($q, $http) {
var sendTasks = function(params) {
var defer = $q.defer();
$http.post('http://localhost:3000/task/save', params)
.success(function(data) {
console.log('data: ' + data);
})
.error(function(err) {
defer.reject(err);
});
return defer.promise;
}
return {
sendTasks: sendTasks
}
});
})(angular);
I am trying to send an ID through to a controller using $routeParams via a factory but it is not working.
My $routeProvider:
.when('/event/:eventId', {
templateUrl : 'pages/event_detail.html',
controller : 'eventPageCtrl'
});
My factory:
myApp.factory('eventRepo', ['$http', function($http) {
var urlBase = 'php/api.php';
var eventRepo = {};
eventRepo.getEvent = function (id) {
return $http.get(urlBase + '?eventID=' + id);
};
return eventRepo;
}]);
My Controller:
myApp.controller('eventPageCtrl', ['$scope', '$routeParams', 'eventRepo',
function ($scope, $routeParams, eventRepo) {
$scope.getEvent = function (id) {
eventRepo.getEvent($routeParams.eventId)
.success(function (data) {
$scope.eventsDetail = data;
})
.error(function (error) {
$scope.status = 'Error retrieving event! ' + error.message;
});
};
}]);
When handling $http.get() inside the controller and not with the factory it works fine so I think I am not passing my $routeParams correctly? Perhaps this line is causing the issue eventRepo.getEvent($routeParams.eventId)?
This works currently, but trying to use $http.get() outside the controller:
myApp.controller('eventPageCtrl', function($scope, $http, $routeParams) {
$http.get("php/api.php?eventID="+$routeParams.eventId).success(function(data){
$scope.eventsDetail = data;
});
});
how about using resolve in your routeProver and returning the eventId and then injecting it in the controller .. example :
$routeProvider:
.when('/event/:eventId', {
templateUrl : 'pages/event_detail.html',
controller : 'eventPageCtrl',
resolve : {
eventId: function($route, $location) {
var eventId = $route.current.params.eventId;
return eventId;
});
Controller:
myApp.controller('eventPageCtrl', ['$scope', 'eventId', 'eventRepo',
function ($scope, eventId, eventRepo) { //add it as a dependency
$scope.eventId = eventId; //you can check this to see if its being assigned
$scope.getEvent = function (eventId) { //Edit: eventId added here
eventRepo.getEvent(eventId) //Edit: eventId passed
.success(function (data) {
$scope.eventsDetail = data;
})
.error(function (error) {
$scope.status = 'Error retrieving event! ' + error.message;
});
};
}]);
I am trying to create an Angular Factory, this is based on a example from a plural site course http://www.pluralsight.com/training/player?author=shawn-wildermuth&name=site-building-m7&mode=live&clip=3&course=site-building-bootstrap-angularjs-ef-azure.
From debugging the code in Chrome it appears to run fine. I can see when I debug it that the service gets my data and puts it in my array but when I look at the controller in either $scope.data or dataService.data the arrays are empty. I don't see any javascript errors. I'm not sure what I'm doing wrong, any suggestions. I'm using AngularJS v1.3.15.
module.factory("dataService", function($http,$routeParams,$q) {
var _data = [];
var _getData = function () {
var deferred = $q.defer();
$http.get("/api/v1/myAPI?mainType=" + $routeParams.mainType + "&subType=" + $routeParams.subType)
.then(function (result) {
angular.copy(result.data,_data);
deferred.resolve();
},
function () {
//Error
deferred.reject();
});
return deferred.promise;
};
return {
data: _data,
getData: _getData
};});
module.controller('dataController', ['$scope', '$http', '$routeParams', 'dataService',function ($scope, $http, $routeParams, dataService) {
$scope.data = dataService;
$scope.dataReturned = true;
$scope.isBusy = true;
dataService.getData().then(function () {
if (dataService.data == 0)
$scope.dataReturned = false;
},
function () {
//Error
alert("could not load data");
})
.then(function () {
$scope.isBusy = false;
})}]);
On
return {
data: _data,
getData: _getData
};});
you have "data: _data," while your array is named just "data". Change the name of the variable to match and it will work:
var _data = [];
Why would you use deferred from $q this way?
The proper way to use $q:
$http.get("/api/v1/myAPI?mainType=" + $routeParams.mainType + "&subType=" + $routeParams.subType)
.success(function (result) {
deferred.resolve(result);
}).error(
function () {
//Error
deferred.reject();
});
And then in controller
dataService
.getData()
.then(function success(result) {
$scope.data = result; //assing retrived data to scope variable
},
function error() {
//Error
alert("could not load data");
});
In fact, there are some errors in your codes :
In your Service, you define var data = [];, but you return data: _data,. So you should correct the defination to var _data = []
you don't define _bling, but you use angular.copy(result.data,_bling);
One more question, why do you assigne the service to $scope.data : $scope.data = dataService ?
EDIT :
Notice that there 3 changes in the following codes:
comment the $scope.data = dataService;, because it makes no sense, and I think that $scope.data should be the data that the service returns.
$scope.data = dataService.data;, as I described in 1st point. You can see the result from the console.
In the if condition, I think that you want to compare the length of the returned data array, but not the data.
module.controller('dataController', ['$scope', '$http', '$routeParams', 'dataService',function ($scope, $http, $routeParams, dataService) {
// $scope.data = dataService;
$scope.dataReturned = true;
$scope.isBusy = true;
dataService.getData().then(function () {
if (dataService.data.length === 0){
$scope.dataReturned = false;
}else{
$scope.data = dataService.data;
console.log($scope.data);
}
},
// other codes...
})}]);
I am starting out on the angular seed. I have a json file that displays items like the below.
{
"id":"1",
"name":"Spain",
"abbrev":"esp"
}
When I click on a country in the list I want to the display the details such as the name for this item.
I have this working as shown below.
/* app.js */
'use strict';
// Declare app level module which depends on views, and components
angular.module('myApp', ['ngRoute','myApp.controllers','myApp.services'])
.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/', {
templateUrl: 'templates/view1.html',
controller: 'CountryCtrl'
});
}])
.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/:name', {
templateUrl: 'templates/view2.html',
controller: 'CountryCtrl'
});
}])
.config(['$routeProvider', function($routeProvider) {
$routeProvider.otherwise({redirectTo: '/'});
}]);
/* services.js */
angular.module('myApp.services', [])
.factory('Countries', ['$http', function($http) {
var Countries = {};
Countries.name = '';
Countries.listCountries = function () {
return $http.get('../api/countries');
},
Countries.ChangeName = function (value) {
Countries.name = value;
}
return Countries;
}]);
/* controllers.js */
angular.module('myApp.controllers', [])
.controller('CountryCtrl', ['$scope', 'Countries', '$location', function($scope, Countries,$location) {
listCountries();
function listCountries() {Countries.listCountries()
.success(function (data, status, headers, config) {
$scope.countries = data.countries;
})
.error(function(data, status, headers, config) {
$scope.status = 'Unable to load data: ' + error.message;
});
}
$scope.name = Countries.name;
$scope.changeView = function(countryName,indx){
$location.path(countryName);
$scope.name = Countries.ChangeName(countryName);
}
}]);
/* templates/view1.html */
<ul>
<li ng-repeat="country in countries">
<div ng-click="changeView(country.name,$index)">{{country.name}}</div>
</li>
</ul>
/* templates/view2.html */
{{name}}
What I can't get to work is that if I go to http://www.example.com/app/#/ then navigate to spain in the list then I get taken to http://www.example.com/app/#/esp and {{name}} gets outputted as esp.
However if I navigate straight to http://www.example.com/app/#/esp without first clicking on spain in the list I get no value in my $scope.name
How can I achieve this?
I want the name to also be set based on the location path if it is available.
I know that $location.$$path will get me /esp however I don't really think this is the best idea to use this incase the url builds out to something bigger eg http://www.example.com/app/#/esp/events
can I some how access the index or id of the item so that I can then access the data like
{{countries[0].name}}
where 0 is id of esp - 1.
What is the best approach?
Mate, there are a couple of issues with your app.
Your service retains "state" although is only used to retrieve information
You're using the same controller to 2 different views (bad practice)
$scope.status = 'Unable to load data: ' + error.message; --> Error is not defined
There are a couple of js errors too, like strayed commas and stuff
Anyways, here's a revised version of your code. Fiddle
// Instantiate your main module
var myApp = angular.module('myApp', ['ngRoute']);
// Router config
myApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'templates/view1.html',
controller: 'CountryListCtrl'
})
.when('/:id', {
templateUrl: 'templates/view2.html',
controller: 'CountryCtrl'
})
}
]);
// Your Factory. Now returns a promise of the data.
myApp.factory('Countries', ['$q',
function($q) {
var countriesList = [];
// perform the ajax call (this is a mock)
var getCountriesList = function() {
// Mock return json
var contriesListMock = [{
"id": "0",
"name": "Portugal",
"abbrev": "pt"
}, {
"id": "1",
"name": "Spain",
"abbrev": "esp"
}, {
"id": "2",
"name": "Andora",
"abbrev": "an"
}];
var deferred = $q.defer();
if (countriesList.length == 0) {
setTimeout(function() {
deferred.resolve(contriesListMock, 200, '');
countriesList = contriesListMock;
}, 1000);
} else {
deferred.resolve(countriesList, 200, '');
}
return deferred.promise;
}
var getCountry = function(id) {
var deferred = $q.defer();
if (countriesList.length == 0) {
getCountriesList().then(
function() {
deferred.resolve(countriesList[id], 200, '');
},
function() {
deferred.reject('failed to load countries', 400, '');
}
);
} else {
deferred.resolve(countriesList[id], 200, '');
}
return deferred.promise;
}
return {
getList: getCountriesList,
getCountry: getCountry
};
}
]);
//Controller of home page (pretty straightforward)
myApp.controller('CountryListCtrl', ['$scope', 'Countries',
function($scope, Countries) {
$scope.title = 'Countries List';
$scope.countries = [];
$scope.status = '';
Countries.getList().then(
function(data, status, headers) { //success
$scope.countries = data;
},
function(data, status, headers) { //error
$scope.status = 'Unable to load data:';
}
);
}
]);
// controller of Country page
// Notice how we use $routeParams to grab the "id" of our country from the URL
// And use our service to look for the actual country by its ID.
myApp.controller('CountryCtrl', ['$scope', '$routeParams', 'Countries',
function($scope, $routeParams, Countries) {
$scope.country = {
id: '',
name: '',
abbrev: ''
};
var id = $routeParams.id;
Countries.getCountry(id).then(
function(data, status, hd) {
console.log(data);
$scope.country = data;
},
function(data, status, hd) {
console.log(data);
}
);
}
]);
In your "CountryCtrl", if you include $routeParams and use $routeParams.tlaname, you will have access to the tlaname. You can then use that to initialize your data.
