custom instance method in Angular $resource

Question

all actions for a AngularJS $resource are added as $customAction methods to the Resource so that I can invoke them as methods on resource instances, e.g.:

var User = $resource('/user/:userId', {userId:'@id'});
User.get({userId:123}, function(user) {
  user.abc = true;
  user.$save();
});

$save is the save action and can be called on the user instance.

I now defined the following custom action, leading to a $attributes method on every instance of user:

var User = $resource('/user/:userId', {userId:'@id'}, {
  attributes: { method: 'GET', url: '/user/:userId/attributes', isArray: true }
});

If I now try to invoke this method, I get the error Object #<Resource> has no method 'push':

User.get({userId:123}, function(user) {
  var attrs = user.$attributes();    // error
  // ...
});

Did I get the concept of custom actions wrong?

It seems that you should use params instead of url

var User = $resource('/user/:userId/:customAction', {userId:'@id'}, {
  attributes: { method: 'GET', params: { userId:'@id', customAction: 'attributes'}, isArray: true }
});

The eventual solution for me was to switch to Restangular. It supports nested resources using a chaining syntax so that I can to the following:

Restangular.one("user", 123).all("attributes").get()
