How to redirect to external URL in Django?

Question

I think this should be easy, but I cannot figure it out. I am trying to write an opt-out view. I am receiving a get request. Through urls.py, I render my opt-out view. In this view, I save some parameters for the user in the database and then I want to redirect the user to an external URL. I tried:

return redirect('http://stackoverflow.com/')

from Django documentation . However, the optout view renders the training template instead of returning the redirect, though the parameters are saved in the database as expected. My code is as follows:

def optout(request):
    if (('REMOTE_USER' in request.META and request.META['REMOTE_USER'] != "") or 
        (request.session.get('userid', False) and request.session['userid'] != "")):
        if ('REMOTE_USER' in request.META and request.META['REMOTE_USER'] != ""):
            userid = request.META['REMOTE_USER']
        if (request.session.get('userid', False) and request.session['userid'] != ""):
            userid = request.session['userid']
        user = User.objects.get(username=userid)
        user.optout = True
        user.postpone = False
        user.save()
        return redirect('http://stackoverflow.com/')
    context = { 'userid': "" }
    return render(request, 'games/Training.html', context)

Any help is highly appreciated.

Answer 1

Yeah, return redirect('http://stackoverflow.com/') is the correct method.

If you do the following, you can confirm that is a working method to redirect.

   from django.shortcuts import redirect

   def optout(request):
       return redirect("http://stackoverflow.com/")

Your conditional statements must not be catching.

Answer 2

using class HttpResponseRedirect

from django.http import HttpResponseRedirect

def out(request):
    return HttpResponseRedirect("http://google.com")

Or:

using class HttpResponse

from django.http import HttpResponse

def out(request):
    response = HttpResponse("", status=302)
    response['Location'] = "http://google.com"
    return response

NOTE:

The last one is useful to redirect from a website to a mobile (Android/Iphone) app. Where location is scheme://host
