django LOGIN_REDIRECT_URL with dynamic value

Question

I\'m trying to redirect a user to a url containing his username (like http://domain/username/), and trying to figure out how to do this. I\'m using django.contrib.auth for m

Answer 1

A solution, is to redirect to a static route like '/userpage/' and have that redirect to the final dynamic page.

But I think the real solution is to make a new view that does what you really want.

from django.contrib.auth import authenticate, login
from django.http import HttpResponseRedirect

def my_view(request):
    username = request.POST['username']
    password = request.POST['password']
    user = authenticate(username=username, password=password)
    if user is not None:
        if user.is_active:
            login(request, user)
            HttpResponseRedirect('/%s/'%username) 
        else:
            # Return a 'disabled account' error message
    else:
        # Return an 'invalid login' error message.

http://docs.djangoproject.com/en/dev/topics/auth/#authentication-in-web-requests

for more information about rewriting the view. This is how the docs say to override this kind of thing.

I use django-two-factor-auth login view which provides OTP features for login. Hence I extend from two_factor's LoginView.

In main urls.py:

from two_factor.urls import urlpatterns as tf_urls
urlpatterns = [
  # make sure login is before default two_factor (tf_urls) urls
  # coz first url has higher preference
  path('account/login/', MyLoginView.as_view(), name='login'),
  path('', include(tf_urls)),
]

In views.py:

from two_factor.views.core import LoginView
from two_factor.utils import default_device


class MyLoginView(LoginView):

    def get_success_url(self):
        if self.is_otp_setup() is True:
            return reverse('homepage:homepage')

        # otp not setup. redirect to OTP setup page
        else:
            return reverse('two_factor:setup')
        
    def is_otp_setup(self):
        if self.request.user and \
                self.request.user.is_authenticated and \
                default_device(self.request.user):
            return True
        else:
            return False

Wrap the auth view in your own custom view and redirect to wherever you want if authentication succeeded.

from django.http import HttpResponseRedirect
from django.contrib import auth
from django.core.urlresolvers import reverse

def login(request):
    template_response = auth.views.login(request)

    if isinstance(template_response, HttpResponseRedirect) and template_response.url == '/accounts/profile/':
        return HttpResponseRedirect(reverse('user', args=(request.user.username,)))


    return template_response

Another alternative is to use the query param next to indicate where to redirect to after the login.

<a href="{% url 'login' %}?next={{ request.path }}">sign in</a>

With the class-based django.contrib.auth.views.LoginView, you can now simply override get_success_url:

urls.py:

url(r'^login$', MyLoginView.as_view(), name='login'),
url(r'^users/(?P<username>[a-zA-Z0-9]+)$', MyAccountView.as_view(), name='my_account'),

views.py

class MyLoginView(LoginView):

    def get_success_url(self):
        return reverse('my_account', args=[self.request.user.username])
