Using decorators to simplify declaring actions on Tastypie Resources

api.py

from utils.api import action, actionurls
from tastypie.resources import ModelResource
from tastypie.authorization import Authorization

class NoteResource(ModelResource):

    class Meta:
        object_class = Note
        queryset = Note.objects.all()
        authorization = Authorization()
        
    def prepend_urls(self, *args, **kargs):
        urls = actionurls(self)
        return urls

    @action()
    def share(self, request, **kwargs):
        return self.create_response(request, {
            'success': True
        })

    @action(name='shareEmail')
    def email(self, request, **kwargs):
        return self.create_response(request, {
            'success': True
        })

util_api.py

    for name, method in self.__class__.__dict__.iteritems():
        if hasattr(method, "is_auto_action"):

            actionName = name if not hasattr(method, "auto_action_name") \
                else method.auto_action_name

            urls.append(
