AngularJS service not invoking error callback on save() method

Question

So I'm using angularjs restful service $resource and I'm calling $save function. However, the error callback I pass to it is not being called. The server is sending a 418 error which I thought since it's NOT 200 would result in the error callback being invoked. But, it never does. I can't find any documentation stating what http error codes will result in the error callback being called.

Here is my code:

var modalScope = $scope.$new();
modalScope.showPassword = false;
modalScope.message = null;
modalScope.user = new User();

modalScope.submit = function(user) {
    user.$save( {}, function(data,headers) {
        // do the success case
    }, function(data,headers) {
        // do the error case                
    });
};

The modalScope.user is being passed to the submit function defined. So what's the problem why this error callback isn't being called?

Answer 1

I found the following in the ngResource source code

$http({method: 'GET', url: '/someUrl'}).
    success(function(data, status, headers, config) {
        // this callback will be called asynchronously
        // when the response is available
    }).
    error(function(data, status, headers, config) {
        // called asynchronously if an error occurs
        // or server returns response with status
        // code outside of the <200, 400) range
    });

I am kind of confused about the range notation but it seems it should actually call the error method. Maybe you found a bug.

Answer 2

Had the same problem and nothing here worked. Turned out I had an custom debug-interceptor that didn't explicitly return a $q.reject(response).

Apparently every custom debug-interceptor completely overwrites the default behavior.

See https://github.com/angular/angular.js/issues/2609#issuecomment-44452795 for where I found the answer.

Answer 3

I had troubles with the error callback as well, but it appears that in more recent versions of AngularJS, the error callback method must now be implemented something like this:

SomeResource.query({}, angular.noop, function(response){
  $scope.status = response.status; 
});

Also, in response to the comments on Flek's post, it seems that now only responses between 200 and 300 are not considered an error.

I couldn't get Alter's answer to work, but this worked for me:

user.$save(function (user, headers) {
                    // Success
                    console.log("$save success " + JSON.stringify(user));
                }, function (error) {
                    // failure
                    console.log("$save failed " + JSON.stringify(error))
                });
