I checked the other questions on here like this one, but couldn't get an accurate answer that would solve my problem. When i run the dev server with python manage.py runserver I get the following `

`
But when i check my other project with which i follow the official django tut I dont have the mentioned views file in the project directory but I am able to see the admin page. Any suggestions why is the error being raised?
i think it will be more useful if just copy / paste error log . use:
./manage.py runserver --traceback
you need to add function in chinatown/views.py say "food"
and a url pattern in project's urls.py:
from django.conf.urls import url
urlpatterns = [
url(r'^food/$', 'chinatown.views.food'),
]

I'm using django-allauth for my django authentication and
while confirming the email i get
TypeError at /accounts/confirmemail/MQ:1mk57U:HtWDA8B5NClWhK2L6nDxJgwlNRGItW_4FyhDqcbcfow/ and it's complaining about argument of type 'bool' is not iterable
as I searched answers were in the cause of using django-rest-allauth and here I'm not using any rest api and facing this issue.

The proplem come from after email confirmation done the reverse url is not valid so you need to go to your setting and check setting for that you must give it valid url to be redircted after confirmation
So I hope to revise the urls

You need to replace django.contrib.sessions in your INSTALLED_APPS with user_sessions if you want to use django-user-sessions. This will setup its models correctly.
Furthermore make sure you have also followed all other installation instructions.

Thank you for adding the traceback. Its the redirect call. So when you use the redirect shortcut method the string you give it needs to match the name variable in at least one of your configured paths. So when I tried to redirect to nothing in my project with:
return redirect("")
I get the exact same error because I have no paths configured for that:
urlpatterns = [
path('<int:key>/authors/', views.get_authors, name='authors'),
path('home/', views.home, name='home')
]
But when i changed my path for home to use the name ="":
urlpatterns = [
path('<int:key>/authors/', views.get_authors, name='authors'),
path('home/', views.home, name='')
]
viola, redirects to home.
I haven't touched the code on my app in weeks but i'm suddenly getting this exact same TypeError on every page, including Admin pages.
The last thing to happen was an update on a model to change a ForeignKey field, but I don't feel the two are related

Exception Value: 'NoneType' object is not iterable
Solved it by looking through some of my own context processors. I had one function that was returning None on a request (after changing an entry and having an empty queryset as a result).
I have url like this http://gagandeepdesk/2690/ which I am filtering with urls.py file and sending 2690 as one of the parameters to the function.
my urls.py filter looks like this,
url(r'^(\d+)/', 'scango.scanner.views.download'),
And that function looks like this,
def download(request, MediaId):
media = Media.objects.get(id=int(MediaId))
#print media
return HttpResponse(FileIterWrapper(open(media.path)))
I am getting error 'too many values to unpack' on line
media = Media.objects.get(id=int(MediaId))
I also tried running this function standalone without request object and it is running perfectly fine. So, I am confused what I have done wrong here.

This is an example of named groups.
In Python regular expressions, the syntax for named regular expression
groups is (?Ppattern), where name is the name of the group and
pattern is some pattern to match.
