How to create a POST request (including CSRF token) using Django and AngularJS

I'm trying to create a POST request using angular.js to this Django view.

class PostJSON4SlickGrid(View):
    """
    REST POST Interface for SlickGrid to update workpackages
    """

    def post(self, request, root_id, wp_id, **kwargs):
        print "in PostJSON4SlickGrid"
        print request.POST
        return HttpResponse(status=200)

Therefore I created this resource.

myModule.factory('gridData', function($resource) {
    //define resource class
    var root = {{ root.pk }};
    return $resource('{% url getJSON4SlickGrid root.pk %}:wpID/', {wpID:'@id'},{
            get: {method:'GET', params:{}, isArray:true},
            update:{method:'POST'}
    });
});

Calling the get method in a controller works fine. The url gets translated to http://127.0.0.1:8000/pm/rest/tree/1/.

function gridController($scope, gridData){
    gridData.get(function(result) {
        console.log(result);
        $scope.treeData = result;
        //broadcast that asynchronous xhr call finished
        $scope.$broadcast('mySignal', {fake: 'Hello!'});  
    });
}

While I m facing issues executing the update/POST method.

item.$update();

The URL gets translated to http://127.0.0.1:8000/pm/rest/tree/1/345, which is missing a trailing slash. This can be easily circumvented when not using a trailing slash in your URL definition.

url(r'^rest/tree/(?P<root_id>\d+)/(?P<wp_id>\d+)$', PostJSON4SlickGrid.as_view(), name='postJSON4SlickGrid'),

instead of

url(r'^rest/tree/(?P<root_id>\d+)/(?P<wp_id>\d+)/$', PostJSON4SlickGrid.as_view(), name='postJSON4SlickGrid'),

Using the workaround without the trailing slash I get now a 403 (Forbidden) status code, which is probably due to that I do not pass a django post angularjs
