Comments on: Using Subdomains in Django

Kind of a late post, but if anyone cares... Rather than parse out the subdomain and store it in the request, I just wanted to be able to handle sub-domains via Django's built in URL dispatcher. The following modification remains backwards compatible with the exist URL patterns. The modification changes the path_info value used by the dispatcher. Patterns used to identify paths originating from a subdomain simply need to search for the regex pattern '^/subname/'.


'''
Example:
'domain.com'           -> ''
'domain.com/doc'       -> 'doc'
'domain.com/doc/'      -> 'doc/'
'sub.domain.com'       -> '/sub/'
'sub.domain.com/doc'   -> '/sub/doc'
'sub.domain.com/doc/'  -> '/sub/doc/'
'domain.com/foo'       -> 'foo'
'foo.domain.com'       -> '/foo/'
'sub1.sub2.domain.com' -> '/sub1_sub2/'
'''

class SubdomainMiddleware:
    def process_request(self, request):
        http_host = request.META.get('HTTP_HOST', '')
        sub_chunks = http_host.replace('www.', '').lower().split('.')[:-2]
        if len(sub_chunks) != 0:
            subdomain = "_".join(sub_chunks)
            request.path_info = "//" + subdomain + request.path_info

Tested with Django 1.3.1 and Python 2.7

Thanks Dave for your reply.

It all works now.

Never would have guessed that the port number was confusing /etc/hosts.

Cheers,

Thanks! I think you actually want this in your localhost

127.0.0.1 subdomain.locahost

Also I find its more useful to use more fun names other than localhost like

127.0.0.1 subdomain.mysite-dev.com

But yeah, the port number :8000 will just confuse the hosts file.

Dear Dave,

Thank you for posting up this solution.

I am trying out what you suggested but I am not able to get the URL to the middleware. The URL I am using is of the form subdomain.localhost:8000. I have also modified my /etc/hosts file as:

127.0.0.1:8000 subdomain.localhost:8000

must I disconnect myself from the internet for this to work? Or must I run the development server 127.0.0.1 without the port number. Kindly please shed some light.

Cheers.

Just found this little gem of a script. Incredibly useful Worked perfectly with the tweaks suggested in the comments.

Use subdomains easily on localhost: (no /etc/hosts modification required)

Thanks a lot! I didn’t think it was going to be this easy when i heard from the IRC guys there was no builtin subdomain support in Django.
