I am using Restangular. In my application, I have two REST resources,
To get the User based on the ID
/users/123
To get the buddy details of the user
users/123/buddies/456
Below is the code I am using,
//get the user
Restangular.one("users", 123).get().then(function(user){
$scope.user = user;
});
Restangular makes a call to /users/123. So far so good.
//get the buddy
var getBuddy = function(){
$scope.user.one("buddies", "456").get();
}
But here, Restangular makes the call to /users/buddies/456 instead of /users/123/buddies/456.
I have gone through the samples provided and I can't spot a mistake. Looks like I am overseeing the obvious but this issue has been frustrating me for more than a day now. Does anyone have a hint?
Thanks,
try forming url like this.
Restangular.one("users", 123).one("buddies", 456).get().then(function(buddy){
$scope.buddy = buddy; });
or remove double quotes of "456" e.g one("buddies", 456), it should work.
The answer lies in the Restangular documentation
If you are using MongoDB, remember to configure the id field.

I have an ng-repeat which is connected to a firebaseArray which is an index of a user's doc Ids.
I want to display a list of their docs with additional info for each one, e.g. it's title and description.
My firebase structure is:
+users
- userId1
-theirDocs
-docId1: true
-docId2: true
+docs
-docId1
- tile
- description
- url
-docId2
- etc etc
I've tried everything and still can't get this to work, it seems a pretty common use case. I've tried using a function that calls a firebaseObject each time. I've tried using a separate controller. I've tried a directive, I've even tried using firebase.utils library (I think out of date now).
Can anyone recommend the best way to do this using AngularFire? Thanks in advance!
It would be better to see a code snippet as to fully understand what you've tried first of all, as it's difficult to determine where the issues lie. That being said, as long as your rules are not preventing this, you may need to wait for the data to download using $loaded function beforehand.
EXAMPLE
This example is clearly available by following this link, yet here is an example for further clarity:
var yourFirebaseReference = firebase.database().ref("REPLACE WITH YOUR FIREBASE BRANCH HERE");
var data = $firebaseArray(yourFirebaseReference);
data.$loaded().then(function(x) {
console.log(data) // Example, you can do what you want with your 'data' now as the data has loaded
x === data; // true
}).catch(function(error) {
console.log("Error:", error);
});
meteor, meteor & angular gurus.
I am really new to angular-meteor and facing the following problem. I perform a search using
$scope.Contacts = $meteor.collection(Contacts,false).subscribe('searchString', $scope.searchString);
or
$scope.Contacts = $scope.$meteorCollection(Contacts,false).subscribe('searchString', $scope.searchString);
and the $scope.Contacts does not refresh. It seems like its holds the old collection (speculation). I can see the data being returned by the mongo server and they look fine.If I iterate through the collection using $meteor.foreach you can see that the data are there.
But once the first search result is assigned to $scope.Contacts it wont refresh any more. I am having the feeling that $scope.Contacts keeps its own "collection" and only append new rows/docs coming from $meteor.collection.
Any help would be greatly appreciated.
Thanks All,
Sotiris
It's kind of weird. From my understanding, subscribe is linking the data pipline, collections is the representative of the data.
$scope.meteorSubscribe('contacts');
$scope.contacts = $scope.$meteorCollection(function (){
Contacts.find({someField: $scope.searchString})
}
You might want something like this?
I want to modify one object via a REST API using Restangular on the client side. I do the following:
Restangular.setBaseUrl('/api/v1');
return Restangular.one('lists', item.listId).one('items',item.order).get().then(function(elem) {
elem.text = item.text;
elem.put();
});
But the put method gets the wrong URL missing the ID for the last member (item.order).
The expected url is /lists/2/items/22 but i get /lists/2/items and the PUT fails.
What could I be doing wrong?
Ok, let me try a theory :)
My comment above was a bit lame because I was focusing on the first part of the code and not the put().
The first part is perfect, you tell Restangular to build the URL with one() methods and the GET request must be very fine.
Then, base on a new Restangular-aware object, you try to persist the change in your API.
However, I believe that Restangular does not actually know what field to use as id in order to build the right query for your elem object.
Did you try to configure, in your Restangular Entity Provider the fields property?
RestangularProvider.setRestangularFields({
id: "orderId",
});
I believe that specifying the right field as id would suffice.
As a bonus, it seems that .save() will use PUT or POST accordingly if it's a new object or not.
Hope this helps
I am trying to make a PUT request using RESTAngular. I am fairly new to Angular as well as RESTAngular.
Following is code snippet which works.
$scope.itemToUpdate = Restangular.all($scope.slug);
$scope.itemToUpdate.getList().then(function(items){
var item = items.one($routeParams.id);
item.name = $scope.singular.name;
item.description = $scope.singular.description;
item.put();
});
This doesn't work.
$scope.itemToUpdate = Restangular.all($scope.slug);
$scope.itemToUpdate.getList().then(function(items){
var item = items.one($routeParams.id);
item = $scope.singular;
item.put();
});
Don't know what am I doing wrong.
$scope.singular gets it data initially as following. Restangular.one('roles', $routeParams.id).getList().$object.
Basically idea is to update this model from form and also prepopulate the form with relevant data when slug matches the id. I can change the way things are wired up if required. So feel free to suggest best practices.
Edit 2
This official demo is very helpful in solving the issue.

When Restangular returns resouce array\object it adds some methods on the object such as put which has been wired up to update the object on put call to server.
In second case you are assigning item=$scope.singular. $scope.singular may not be a Restangular object and hence does not work.

Using Restangular for AngularJS, keep getting an object object from Mongolab.
I'm sure it has to do with Promise but not sure how to use/implement this coming from old Java OO experience.
(Side note, would something like Eloquent Javascript, some book or resource help me understand the 'new' Javascript style?)
The small web app is for Disabled Students and is to input/edit the students, update the time they spend after school and then output reports for their parents/caregivers every week.
Here's the code that returns undefined when popping up a new form (AngularJS Boostrap UI modal)
I personally think Restangular & the documentation is a great addition so hope it doesn't dissuade others - this is just me not knowing enough.
Thanks in advance
app.js
...
$scope.editStudent = function(id) {
$scope.myStudent = Restangular.one("students", id);
console.log($scope.myStudent);
}
I'm the creator of Restangular :). Maybe I can help you a bit with this.
So, first thing you need to do is to configure the baseUrl for Restangular. For MongoLab you usually do have a base url that's similar to all of them.
Once you got that working, you need to check the format of the response:
If your response is wrapped in another object or envelope, you need to "unwrap" it in your responseExtractor. For that, check out https://github.com/mgonto/restangular#my-response-is-actually-wrapped-with-some-metadata-how-do-i-get-the-data-in-that-case
Once you got that OK, you can start doing requests.
All Restangular requests return a Promise. Angular's templates are able to handle Promises and they're able to show the promise result in the HTML. So, if the promise isn't yet solved, it shows nothing and once you get the data from the server, it's shown in the template.
If what you want to do is to edit the object you get and then do a put, in that case, you cannot work with the promise, as you need to change values.
If that's the case, you need to assign the result of the promise to a $scope variable.
For that, you can do:
Restangular.one("students", id).get().then(function(serverStudent) {
$scope.myStudent = serverStudent;
});
This way, once the server returns the student, you'll assign this to the scope variable.
Hope this helps! Otherwise comment me here!
Also check out this example with MongoLab maybe it'll help you :)
