I am getting this error while running my django application.

    Internal Server Error: /

The urls.py file

    from django.conf.urls import patterns, include, url
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^articles/', include('article.urls')),
    # Examples:
    # url(r'^$', 'DjangoBlog.views.home', name='home'),
    # url(r'^DjangoBlog/', include('DjangoBlog.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),

    # User registration
    url(r'^accounts/login/$', 'DjangoBlog.views.login'),
    url(r'^accounts/auth/$', 'DjangoBlog.views.auth_view'),
    url(r'^accounts/logout/$', 'DjangoBlog.views.logout'),
    url(r'^accounts/loggedin$', 'DjangoBlog.views.loggedin'),
    url(r'^accounts/invalid/$', 'DjangoBlog.views.invalid_login'),
    url(r'^accounts/register/$', 'DjangoBlog.views.register_user'),
    url(r'^accounts/register_success/$', 'DjangoBlog.views.register_success'),  
)

The article urls.py file is

    from django.conf.urls import patterns, include, url
from api import ArticleResource

article_resource = ArticleResource()

urlpatterns = patterns('',
    url(r'^all/$', 'article.views.articles'),
    url(r'^get/(?P<article_id>\d+)/$', 'article.views.article'),
    url(r'^language/(?P<language>[a-z\-]+)/$', 'article.views.language'),
    url(r'^create/$', 'article.views.create'),
    url(r'^like/(?P<article_id>\d+)/$', 'article.views.like_article'),
    url(r'^add_comment/(?P<article_id>\d+)/$', 'article.views.add_comment'),
    url(r'^search/$', 'article.views.search_titles'),
    url(r'^api/', include(article_resource.urls)),
)

The article api.py file

# from tastypie.resources import ModelResource
from tastypie.resources import ModelResource, ALL, ALL_WITH_RELATIONS
from tastypie.constants import ALL
from models import Article

class ArticleResource(ModelResource):
    class Meta:
        queryset = Article.objects.all()
        resource_name = 'article'
        filtering = { "title" : ALL }
