Creating Django sessions

Question

I am facing a problem while building a Django web app. I want that if a user logs into his account, his session should be stored and when he agains visits the login page ,he should be redirected to his home page. I have tried using

Here is my code.

Views.py

from django.http import HttpResponse
from django.shortcuts import render_to_response
from django.contrib.auth.decorators import login_required
from django.template import RequestContext

def index(request):
    return HttpResponse("Index Page")

@login_required
def home(request):
    ctx = {}
    return render_to_response('auth/home.html',ctx, context_instance = RequestContext(request))

Urls.py

from django.conf.urls.defaults import *
from django.contrib.auth.views import login, logout
urlpatterns = patterns('',
url(r'^$','apps.auth.views.index'),

)


urlpatterns = patterns('',
url(r'cc/', login, kwargs = {'template_name' : 'auth/cc.html'} , name = 'cc_login'),
url(r'logout/', logout, name = 'cc_logout'),
url(r'home/','apps.auth.views.home', name = 'cc_home'),
)

Answer 1

I ran into the same situation with my django project.

I solved it by making a view that was similar too:

def login_page(request):
    if request.user.is_authenticated():
        return redirect(<insert your desired page here>)
    else:
        return render(<whatever the login page is>)

This way, if the user is logged in, they will be redirected to whatever page you want them to be.

EDIT:

In response to the comments below, I am modifying my answer (original is still above). Here is what I have done to solve your problem.

from django.contrib.auth.views import login

def custom_login(request, **kwargs):
    """
        Redirects the user to the desired page if they are authenticated
    """
    if request.user.is_authenticated():
        return redirect(<whatever page or view you want them to go to>)
    else:
        return login(request, **kwargs)

For example, your kwargs could be {'template_name': 'your_login_template.html', 'authentication_form': YourCustomRegistrationFormClass}

If you're using the standard login and registration procedures, just leave the kwargs part blank.

I'm fairly new to Django, but have you tried overriding the default login view?

views.py

from django.contrib.auth import views as auth_views
from django.shortcuts import redirect

def login(request, *args, **kwargs):
    if request.method == 'POST':
        request.session.set_expiry(0) # Remember user session
    if request.user.is_authenticated():
        return redirect(USER_PAGE_ADDRESS)
    return auth_views.login(request, *args, **kwargs)

urls.py

urlpatterns = patterns('',
    url(r'cc/', APP_NAME.views.login, kwargs = {'template_name' : 'auth/cc.html'} , name = 'cc_login'),
    ...
)
