Django and urls.py: How do I HttpResponseRedirect via a named url?

Question

I'm writing a member-based web application, and I need to be able to redirect the page after login. I want to use the named url from my urls.py script in my views.py file for the login application, but I can't for the life of me figure out what to do. What I have is this:

def login(request):  if request.session.has_key('user'):     if request.session['user'] is not None:         return HttpResponseRedirect('/path/to/page.html') 

What I want to accomplish is something like:

def login(request):  if request.session.has_key('user'):     if request.session['user'] is not None:         return HttpResponseRedirect url pageName 

I get syntax errors when I execute this, any ideas?

Answer 1

You need to use the reverse() utils function.

from django.urls import reverse # or Django < 2.0 : from django.core.urlresolvers import reverse  def myview(request):     return HttpResponseRedirect(reverse('arch-summary', args=[1945])) 

Where args satisfies all the arguments in your url's regular expression. You can also supply named args by passing a dictionary.

Answer 2

The right answer from Django 1.3 onwards, where the redirect method implicitly does a reverse call, is:

from django.shortcuts import redirect  def login(request):     if request.session.get('user'):         return redirect('named_url')
