how to pass variables between functions Django?

Question

I have a function like this in views.py:

def signin(request):
    if request.method == 'POST':
        uname = request.POST['username']
        pwd = request.POST['password'] 
        #and other code

And then i have another function like this:

def reservations(request):
    try:
        c = Utilisateur.objects.get(username = uname)
        reserve = Reserve.objects.get(client = c)
        return render (request, 'reservation.html', {'reserve':reserve})
    except:
        return HttpResponse ('you have no reservations!')

And i want to use the "uname" variable of the first function but it doesn't work any solution?

cant you use a sessions to store values session = sessions.Session() — Midhun Raj

If you're signing in the user in your signin view, then you don't need to pass uname. Assuming you're using the built in django authentication, you can access the User object as request.user any time after they are logged in. Django sets a cookie so it knows who the user is. — little_birdie

In the first view, save the value in the session:

def signin(request):
    if request.method == 'POST':
        uname = request.POST['username']
        request.session['uname'] = uname

Then in the second view, fetch the value from the session:

def reservations(request):
    try:
        uname = request.session['uname']
        c = Utilisateur.objects.get(username = uname)
