django.core.exceptions.ImproperlyConfigured: The included URLconf 'image_storage.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.
And I have no idea about to solve it. What am I missing?
Check the file urls.py that may exist in image_storage django app. It should contain a valid django url configuration and not be empty!
So often times this is caused by some exception when Django's resolvers.py tries to consume your urls.py.
The way I generally solve it is to wrap my entire urls.py file (along with all other urls.py files) in a try-except block, and print the exception that gets caught, which is often much more immediately useful to solving the problem than the default one Django provides.
Good luck!

you need to use it with rest_framework because of this line path('auth',include('rest_framework.urls'), name='rest_framework'),
you can update reverse by reverse(rest_framework) or you can change line to path('auth',include('rest_framework.urls'), name='auth'),
I'm getting a the url conf correct for my web app, and I'm at a loose end.
I think the idea behind django-subdomains is that the subdomain routing is stored in the SUBDOMAIN_URLCONFS
ROOT_URLCONF = 'creativeflow'
# A dictionary of urlconf module paths, keyed by their subdomain.
SUBDOMAIN_URLCONFS = {
None: ROOT_URLCONF + '.urls', # no subdomain, e.g. ``example.com``
'www': ROOT_URLCONF + '.urls',
'blog': 'blog.urls',
}
Then my creativeflow.urls and blog.urls are:
"""Creativeflow URL Configuration."""
from django.conf.urls import url
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls, name="admin"),
]
And
"""Creativeflow URL Configuration the blog app."""
from django.conf.urls import url
from .views import BlogListView
urlpatterns = [
url(r'posts/^(?P<year>\d{4})/(?P<months>\d{2}|\w{3})/(?P<day>\d{2})',
BlogListView.as_view(paginate_by=25), name="blog-list-view")
]

I'm assuming that, as you can see, I have an urlpatterns in both urls.py. So I must have a circular reference. But I've followed the imports from through views.py and models.py and I don't see anything that would cause a circular dependency problem.
How do I resolve this/and find the circular dependency?
Your ROOT_URLCONF points to a module without any patterns. The ROOT_URLCONFmodule must at least have a urlpatterns attribute, even if it's an empty list. You probably want this to point to creativeflow.urls.

Please help how to resolve this error.
In one of your urls.py files, you have a string in the list of URL patterns. This could be because you forgot to remove the prefix when you switched from patterns(prefix, ...) to a list of url()s.
You need to look through your urls.py and find something like:
urlpatterns =[
'' # <- this is the problem, remove this string
url(...)
url(...)
]
Unfortunately, it's not possible for us to tell which urls.py the problem is in. You could try commenting out the includes() one by one. If the error stops, then you've found the one that's causing the problem.
In Django 1.10, the url checks have improved slightly, the check_pattern_startswith_slash won't fail any more, and you'll get a specific warning about the string instead.

Another possible solution is to use the 'debugtoolbar.panels' setting in your config file to disable the request_vars panel (which is what is causing the issue):

Pymongo's Database and Collection objects respond to __getattr__ in order to provide a nicer interface and let you write code like:
db.foo.bar.find(...)
Any call to __getattr__ will succeed, but unfortunately this confuses some libraries which expect certain attributes to be callable (the Pymongo Collection object is not callable, except to raise that exception you're seeing above).
What I've done in Pyramid projects is only use the database from within the resources, to prevent references to the database or collections from becoming present in the module level in views or other code. As an added benefit, this ends up being a good way of enforcing separation of concerns so that resources handle database manipulation, and views only translate that for display in the templates.
That error means that your trying to call a method (html) that doesn't exist in the Database instance.

You somehow set some function to a tuple. Please edit the question and paste your urls.py code, so we can point you to the error.
I can try a wild guess:
File "c:\projects\iFriends\..\iFriends\urls.py", line 17, in <module>
(r'^admin/', include('django.contribute.admin.urls'))
This somehow tells me that you missed a comma on line 16, so:
16. (r'^/', 'some_stuff....') # <-- missed comma here
17. (r'^admin/', include('django.contribute.admin.urls'))
Just put the comma and it will work. If that's not the case, I'll send my cristal ball for mainantance. Paste the code.
EDIT
Seems like you have pasted the urls.py as an answer. Please edit the question and paste urls.py there.
Anyway, the error has changed. What did you do? In this new error, urls.py is not found anymore so maybe you've renamed it? Have you changed the way you run the application?
The file you pasted is not the one that is running. Are you pasting url.py and django is reading urls.py? The code in the error doesn't match the code you pasted! Please paste the correct file, i.e. the same that gives the error, or we can't help.
