python - 如何在 Django 函数之间传递变量？

Question

我在 views.py 中有这样一个函数:

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

然后我有另一个这样的函数:

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!')

我想使用第一个函数的“uname”变量，但它不起作用任何解决方案？

在第一个 View 中，将值保存在session中:

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

然后在第二个 View 中，从 session 中获取值:

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