JQuery ajax call with django session - ajax

Question

I have a site that uses custom authentication in Django that authenticates to a web service using a username, password, and domain. I need to store this information for every subsequent view's request object.
All seems to be going well until I try to make a jquery $.ajax call, debugging the view that gets called from the ajax request I have no session information and the user is AnonymousUser.
I need the session variables to make subsequent calls to the web service for data to display. I've tried a few things in there but nothing seems to work correctly. I want to make sure users a logged in before being able to submit these web service queries as I want to keep the username/domain to lookup the password (and not have it on the client side) in the view and ensure the user is always logged in.
views.py
def login(request):
if settings.DEBUG == True:
print "views.login:Attempting loging at views.login(request)"
if request.method == 'POST':
if settings.DEBUG:
print "views.login: method is POST"
form = LoginForm(request.POST)
if form.is_valid():
if settings.DEBUG:
print "Form is valid, attepmting to authenticate"
Login(request, form.get_user())
str = reverse('cm_base.views.index')
request.session['username']=form.get_user()
request.session['domain']=form.get_domain()
return render_to_response('cm_base/index.html',
{"DEBUG": True,
"user":request.session.get('username'),
'tabs': settings.TAB_LIST},
context_instance=RequestContext(request))
else:
# Their password / email combination must have been incorrect
pass
else:
form = LoginForm()
return render_to_response('cm_base/login.html',
{"DEBUG": True,
'form' : form
},
context_instance=RequestContext(request))
#login_required()
def index(request):
if request.method == 'POST':
print "POSTING"
if settings.DEBUG == True:
print "views.index:Opening index"
return render_to_response('cm_base/index.html',
{"DEBUG": True,
"user":"user",
'tabs': settings.TAB_LIST},
context_instance=RequestContext(request))
#login_required()
def scorecard(request):
user = CustomUser.objects.get(username=request.session.get('username'),
domain=request.session.get('domain'))
*fails on the above line with DoesNotExist: CustomUser matching query does not exist. Lookup parameters were {'username': None, 'domain': None}
base.js
$.ajax({
url : path,
data: $(this).serialize(),
headers: {'X-CSRFToken':getCookie('csrftoken')
,'sessionid':getCookie('sessionid')
},
success : function(data) {
console.log($(this));
//refresh right div
$('#contentpane').empty();
$('#contentpane').html(data.rhtml);
console.log(data.rhtml);
}
});

Looks like my implementation of the backend that was the problem.
backends.py
class CustomBackend(object)
...
def get_user(self, username):
try:
return CustomUser.objects.get(username=username)
except CustomUser.DoesNotExist:
return None
This is called during session passing and actually uses a the primary key which is a userid, not username so this was always returning no user and defaulting to anonymous user. I misinterpreted when the documentation says the userid can be anything, including username, I thought I could pass that in as such but I have both an auto generated userid as well as a username on the object.
