I am trying to make a POST request via $resource object in Angular.
I have something like
(function (angular) {
angular.module('myApp')
.factory('myService', [
'$resource',
function ($resource) {
var serviceObj = $resource('http://testProject/products/', {id: '#id'},{
'createItem' : {
url: 'http://testProject/item/:id',
method: 'POST',
params: {type: ‘#type'}
}
});
return serviceObj;
}
]);
})(angular);
in my controller
//omit the controller codes…
myService.type = ‘Detail’;
myService.createItem(function(data) {
console.log(data)
});
I see stuff back from the console.log but it has the wrong data because the type is shown as ‘Name’ instead of ‘Detail’. I know api supports that and I don’t see anything wrong with my service. Can someone help me out for it? Thanks a lot!
It looks like your are getting data back,
I would try:
console.log(data.data);
Since your are returning an object from your service.

i have problem with ngResource.
here is my .factory
app.factory('sveKlupeServiceFactory', ['$resource',
function($resource){
return $resource('myURL/to/json', {},{
// { method: 'getKlupe', q: '*' },
query: { method: 'GET', params:{klupaId:'klupe'}, isArray:true}
});
and here is my controller
app.controller('klupeController', ['$scope', 'sveKlupeServiceFactory', function ($scope,sveKlupeServiceFactory){
$scope.klupe = sveKlupeServiceFactory.query();
}]);
and in html I have this
<tr ng-repeat="klupa in klupe">
<td>{{klupa.serial_number}}</td>
<td>{{klupa.location_id}}</td>
<td>{{klupa.type}}</td>
<td>{{klupa.last_report_dt}}</td></tr>
Problem:
in my browser I have table, but with empty row. There is no any error.
In my app I have
var app = angular.module('App', [
'ngRoute',
'ngResource']);
Can someone help me with any suggestion?
Thank you.
If you want entire table data, then there is no need to pass id as parameters in factory.Make the following changes in controller while calling factory method.
Check the response using console.log()
sveKlupeServiceFactory.query(function(res){
console.log(res);
$scope.klupe = res;
});
You should use promises to get the response.
$scope.klupe = sveKlupeServiceFactory.query();
$scope.klupe.$promise.then( function(result) { $scope.klupe = result });
I am learning about the MEAN stack, and have created a REST API which posts a review to a collection in MongoDB.
I have defined a service as given:
angular.module('myApp')
.constant('baseURL', 'http://localhost:8080/');
angular.module('myApp')
.service('addReviews', ['$resource', 'baseURL', function($resource, baseURL) {
this.getReviews = function() {
return $resource(baseURL+'reviews/', null, {'save': {method: 'POST'}});
};
}]);
Now, I am calling this service from my controller:
angular.module('myApp', ['ngResource'])
.controller('reviewController', ['$scope', 'addReviews', function($scope, addReviews) {
$scope.reviewSubmit = function() {
$scope.receivedReviews = false;
var review = {
// some data
};
$scope.reviews = addReviews.getReviews().query(
function(response) {
$scope.reviews = response;
$scope.receivedReviews = true;
},
function(response) {
$scope.reviews = response;
// print error message
}
);
console.log($scope.reviews); // showing empty array
};
}]);
In routes.js, I have configured my route as:
var Reviews = require('./models/reviews');
...
app.post('/reviews', function(req, res) {
Reviews.create(req.body, function(err, post) {
if (err) {
return res.send(err);
}
return res.json(post);
});
});
I am trying to post a new review to the Reviews collection. However, $scope.reviews is showing an empty array. I logged the requests, and it shows a GET request is being to /reviews instead of POST. I think I should use save() instead of query(), but I have seen some tutorials online where they used query() despite the method being PUT/POST in the service. I am really confused. Can anyone point out how I can post the data (in var review) to the Reviews collection?
There are some issues with your code on the angular side of things.
You want to use $resource as an all-purpose object to communicate with the API. It has built-in functionality to:
query: get all resources from a given API endpoint
get: a single resource, usually by specifying that resource's id
save: post, with an object sent across in the body of the request. NOTE: you don't need the {'save': {method: 'POST'}} in your $resource configuration, you get it for free.
remove and delete: self-explanatory
So you'd want to set up your reviews factory (incl. url constant) like:
angular.module('myApp', ['ngResource'])
.constant('baseURL', 'http://localhost:8080/')
.factory('Reviews', ['$resource', 'baseURL', function($resource, baseURL) {
return $resource(baseURL+'reviews/:id', {id: '#id'});
}]);
If you want to have access to all saved reviews in your controller, as $scope.reviews, you'd do something like:
angular.module('myApp')
.controller('reviewController', ['$scope', 'Reviews', function($scope, Reviews) {
// hit API endpoint to get all reviews
// will have to have app.get('/reviews', function(req, res) {...})
// configured in your node code
Reviews.query(function(data) {
$scope.reviews = data;
}, function(error) {
console.log(error);
});
// and if you want to take a user-written review, say $scope.userReview,
// from the view and save it to the database on click function submitReview()...
$scope.userReview = {
message: '',
createdTime: null
};
// ^ not sure what your ReviewSchema looks like on the backend, but for example...
$scope.submitReview = function() {
if ($scope.userReview.message.length) {
$scope.userReview.createdTime = Date.now();
Reviews.save($scope.userReview);
// ^ this will make POST request with the $scope.userReview object as the request body
}
};
}]);
The create method on your back end looks fine. The object (or maybe just string) you send across will have to match your review schema. You may want to log the request body to make sure you're getting what you expect.
Have a look at this short post on using $resource to interact with RESTful APIs, and (the slightly more confusing) angular $resource docs, for more information on the $resource service.
Hope this helps you!
I am using a MEAN stack and I am a little confused on how the $resource works. I understand that the $resource factory is a service that retrieves data for controllers. However, I have two model objects, Compositions and Critiques. What I am trying to do is get critiques based off the url, which looks something like this: /compositions/:compositionId/review.
For some reason whenever I call
Reviews.query(function(review) {
console.log(review);
$scope.reviews= review;
});
I get this error:
GET localhost:3000/compositions/review 500 (Internal Server Error)
Here are my services:
angular.module('mean').factory('Reviews', ['$resource',
function($resource) {
return $resource('compositions/:docId/review', {
docId: '#docId'
},
{
update: {
method: 'PUT'
}
});
}
]);
angular.module('mean').factory('Compositions', ['$resource',
function($resource) {
return $resource('compositions/:compositionId', {
compositionId: '#_id'
},
{
update: {
method: 'PUT'
}
});
}
]);
The second one works if I navigate to /compositions/:compId, but the first one does not. Instead I get the error above. Why isn't the docId being passed in? Any ideas?
I want the compositionId, which is the docId in the 'critique' object models terms, but I want to get back critique objects. What am I doing wrong? Any help or advice is appreciated, thanks!
You are passing callback to query() - that is wrong. You should pass there a params object with your docId. This is how you should do that (in Angular 1.2)
Reviews.query({docId: 5}).$promise.then(function(review) {
console.log(review);
});
Hi I'am trying a simple example of using a controller and a factory to get some data back to the view but for some reason I can't print it.
I managed to get the ajax call to work.
If I type the
$scope.sampleStyles = [{ sample: 'text here', text : 'dasdas'}
and don't use the ajax call it works
UPDATE: if I add an alert before assigning to my scope it works (ajax has time to do his thing)
anyone know how to overcome that?
CODE:
var packageApp = angular.module("packageApp", []);
packageApp.controller("MyController", function($scope, myFactory){
$scope.sampleStyles = [];
function init(){
$scope.sampleStyles = myFactory.getSampleStyles();
}
init();
});
packageApp.factory('myFactory', function($http, $log){
var factory = {};
var sampleStyles = [];
var tempData = {};
factory.update = function(){
$.ajax({
type: 'POST',
url: '/account/fetch-sample-styles',
data: {
source: 'ajax'
},
success: function(data, textStatus, XMLHttpRequest){
tempData = data;
}
});
alert(tempData);
sampleStyles = tempData;
}
factory.getSampleStyles = function(){
factory.update();
return sampleStyles;
};
return factory;
});
Are you using the AngularJs $http service? If so it will return a promise which you then operate on. Here is more on promises from the AngularJs docs.
My guess is, you are using an ajax.get(...) with a success callback defined inside. The problem is probably due to the success callback not belonging to the "AngularJs world."
To fix this, you need to tell AngularJs that its scope has changed. Use the $[Root]scope.$apply() function, and have the scope injected into your service as a dependency.
Something like this inside the factory:
$.ajax({
url: "/api/some/end/:point",
...
success: function(data) {
$scope.$apply(function() {
$scope.sampleStyles = data; // etc
});
}
});
I strongly recommend that you look into the $http service, it makes the above code much nicer, and is designed to play nice with the $scope.
$http.get("/api/end/point").then(function(response) {
// response.data points at the page data sent back, assuming that your
// api endpoint sends back JSON of the likes of
// { status: "SUCCESS", styles: [...] }
$scope.sampleStyles = response.data.styles;
});
EDIT:
Now that you posted some code, it seems like the root of your issue is based on the fact that the ajax get is an async call. Why are you even messing with using a temporary variable? Why not the following?
factory.update = function(){
$.ajax({
type: 'POST',
url: '/account/fetch-sample-styles',
data: {
source: 'ajax'
},
success: function(data, textStatus, XMLHttpRequest){
sampleStyles = data;
}
});
}
If you really wanted to make the $.ajax call blocking, you can set async: false in the $.ajax properties.
EDIT 2:
Fixed some broken links, sorry I am a SO newb :(
my service has to use a query string due to limitations on the server that runs classic ASP:
angular
.module('myServices', ['ng', 'ngResource'])
.factory('Item', ['$resource',
function ($resource) {
return $resource('/api/?p=item/:id');
}]);
and I want to add extra query string parameters to it:
Item.query({test: 123}, on_success, on_error);
but the resulting url is
/api/?p=item?test=123
apparently there is a bug, but how to get around it?
EDIT: filed this at https://github.com/angular/angular.js/issues/1511
You can use resource parameters. If you haven't specified placeholders in the path, they would automatically be converted into query string params. Like that:
angular
.module('myServices', ['ng', 'ngResource'])
.factory('Item', [
'$resource',
function ($resource) {
return $resource('/api');
}]);
Item.query({p: 'item/1'});
This would result in a request to /api?p=item/1.
P.S.
I suppose you already know that, but you don't like it. But I still think this is the correct way in your case. Considering the bad API design you are dealing with that back-end you could wrap the AngularJS resources with another service which does this for you.
var deferred = $q.defer();
api.api_name.query({
'param':param_value
},
function(response) {
deferred.resolve(response);
},
function(response) {
deferred.reject(response);
}
);
//
angular
.module('module_name')
.factory('api',function($resource){
var api_var={};
api_var.api_name = $resource('url?param_key=:param', {
param: '#param'
}, {
'query': {
method: 'get'
}
});
return api_var;
});
