How do I get user IP address in django?

Question

How do I get user's IP in django?

I have a view like this:

# Create your views from django.contrib.gis.utils import GeoIP from django.template import  RequestContext from django.shortcuts import render_to_response   def home(request):   g = GeoIP()   client_ip = request.META['REMOTE_ADDR']   lat,long = g.lat_lon(client_ip)   return render_to_response('home_page_tmp.html',locals()) 

But I get this error:

KeyError at /mypage/     'REMOTE_ADDR'     Request Method: GET     Request URL:    http://mywebsite.com/mypage/     Django Version: 1.2.4     Exception Type: KeyError     Exception Value:         'REMOTE_ADDR'     Exception Location: /mysite/homepage/views.py in home, line 9     Python Executable:  /usr/bin/python     Python Version: 2.6.6     Python Path:    ['/mysite', '/usr/local/lib/python2.6/dist-packages/flup-1.0.2-py2.6.egg', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/local/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages', '/usr/lib/pymodules/python2.6']     Server time:    Sun, 2 Jan 2011 20:42:50 -0600

def get_client_ip(request):     x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')     if x_forwarded_for:         ip = x_forwarded_for.split(',')[0]     else:         ip = request.META.get('REMOTE_ADDR')     return ip 

Make sure you have reverse proxy (if any) configured correctly (e.g. mod_rpaf installed for Apache).

Note: the above uses the first item in X-Forwarded-For, but you might want to use the last item (e.g., in the case of Heroku: Get client's real IP address on Heroku)

And then just pass the request as argument to it;

get_client_ip(request)
