Django and Bad Request (400)

Question

I created new django project; added to my settings.py:

DEBUG = False
ALLOWED_HOSTS= [
    'localhost',
    'my_site.com'
]

created app test_view; added hello_world to test_view.views

from django.http.response import HttpResponse

def hello_world(request):
    return HttpResponse('Hello World!!!')

added test route to urls.py url(r'test/', 'test_view.views.hello_world'); fixed /etc/hosts

127.0.0.1    localhost my_site.com

Now when i'm trying to access http://my_site.com:8000/test/ django returns Bad Request (400). But when url is http://localhost:8000/test/ I can see my Hello World page. What can be wrong?

UPD: The same result with DEBUG = True

UPD2:

One more working hostname is ubuntu-virtualbox (computer's name). But even when I changed computer's name to my_site, ubuntu-virtualbox was still available and my_site returned Bad Request (400)

May it be because of some system settings? (it's clean ubuntu in virtualbox). Or maybe problem in virtualenv? Is there a way to trace the error?

Also, your etc/hosts should only include `127.0.0.1 my_site.com`. — Henrik Andersson, Aug 18 '14 at 07:08
beginning with `.` will match my_site.com or www.my_site.com — Raja Simon, Aug 18 '14 at 07:11
Still no result. I'll try to add a new virtualenv and clean project. — Anton, Aug 18 '14 at 07:22
did you try to clean your arp-cache table, you have to open cmd such as administrator and write netsh interface ip delete arpcache — golazo, Aug 18 '14 at 07:54
It looks like django can see if request isn't passed through dns server. Installation and configuration of bind9 instead of changes in /etc/hosts solved this problem. — Anton, Sep 07 '14 at 20:41

It might be a bad Cookie. Try deleting them.

You need another line in your hosts file.

127.0.0.1     localhost
127.0.0.1     my_site.com

Then in your ALLOWED_HOSTS...

ALLOWED_HOSTS = [
    'localhost',
    '.my_site.com', # not 'my_site.com'
]

ALSO, and this is probably important seeing as you are running your site from a virtual machine, when you run the site with python manage.py runserver, run it like this...

python manage.py runserver virtual.server.ip.address:8000

Obviously replace 'virtual.server.ip.address' with that virtual machines actual ip address.

It says `Error: That IP address can't be assigned to` error – Saras Arya Jan 30 '17 at 09:59
@SarasArya try to run the development server like this `python manage.py runserver 0.0.0.0:8000` That will basically have it run on whatever your current ip address is. You should still be able to access the site from `localhost:8000` or `127.0.0.1:8000`. I hope that helps. – teewuane Jan 30 '17 at 21:45
