Well, I have my own session and authentication routines in my app. When a user goes to app/login/ page, if he or she is not loggen in, then he/she sees a form to submit, otherwise I want to redirect the user to the root page app/. login view looks like this:
def index(request):
if sessionCheck(request):
# here I want to redirect one level above to app/
pass
else:
template = loader.get_template('login/login.html')
... other code which is not important
In PHP, I think, I would do it like this:
header("Location: /");
exit;
But how should I do exactly the same thing in Django?
You can use the redirect shortcut function:
from django.shortcuts import redirect
return redirect('some-view-name')
You can also specify a URL apart from a named view. So if your index url does not have a name, you can specify '/'.
This shortcut function is essentially the same as:
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
return HttpResponseRedirect(reverse('some-view-name'))
In order to have a named view, in your urls.py you have to provide a name argument. For instance:
urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^some-view$', views.something, name='some-view-name'),
]
More on that on Django tutorial, Django URL dispatcher.
