URLconf error on Django Heroku deployment

Question

I am getting the following error on my Django Heroku deployment, not sure what is causing it?:

Page not found (404)
Request Method: GET
Request URL:    https://blogpod.herokuapp.com/
Using the URLconf defined in blogpodapi.urls, Django tried these URL patterns, in this order:
^admin/
^api/
^favicon\.ico$
^media\/(?P<path>.*)$
The current URL, , didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

The log generated by Heroku is as follows:

My folder structure is as follows:

My urls.py looks like this:

from django.conf import settings
from django.conf.urls import include, url
from django.conf.urls.static import static
from django.contrib import admin
from django.views.generic.base import RedirectView

favicon_view = RedirectView.as_view(url='/static/favicon.ico', permanent=True)

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^api/', include('api.urls')),
    url(r'^favicon\.ico$', favicon_view),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Answer 1

To define the root url you have to add this pattern '^$':

url(r'^$', view)

Then it matches to your case https://blogpod.herokuapp.com/
