ModuleNotFound error in django in Django tastypie web application

Question

I am pretty new to Django.

When i try to include the urls from the api.py file it returns me an error.

Here is api.py file from the articles app folder

from tastypie.resources import ModelResource
from tastypie.constants import ALL
from article.models import Article


class ArticleResource(ModelResource):
    class Meta:
        querySet = Article.objects.all()
        resource_name = 'article'

here is the urls.py file from the article app folder

from django.conf.urls import url
from article.views import *
from .api import ArticleResource
from django.conf.urls import include

article_resource = ArticleResource()

urlpatterns = [
 url(r'^api/',include('article_resource.urls'))
]

and the error i get back is this

Removing quotes from include will solve the problem

urlpatterns = [
 url(r'^api/',include(article_resource.urls))
]

NOTE: Django include functions uses python's import_module to import the module from string, but here, the article_resource is only available in your local scope.
