设置和获取Django会话变量

Question

这里我正在尝试设置会话变量guest_email_id并尝试打印它们。

def guest_register_view(request):
  form = GuestForm(request.POST or None)
  next_get = request.GET.get("next")
  next_post = request.POST.get("next")
  redirect_path = next_get or next_post or None
  if form.is_valid():
    email = form.cleaned_data.get("email")
    new_guest_user = GuestEmail.objects.create(email=email)
    request.session["guest_email_id"] = new_guest_user.id
    print(new_guest_user.id)
    print(request.session.get('guest_emial_id'))
    if is_safe_url(redirect_path, request.get_host()):
      # print(redirect_path)
      return redirect(redirect_path)
    else:
      return redirect("register")
  context = {
    "form" : form
  }
  return render(request, "accounts/register.html", context)

此视图的网址：

path('register/guest/', guest_register_view, name="guest_register"),

我能够创建仅具有一个字段（电子邮件）的GuestEmail对象并获取其ID，但是我没有获得我要设置的会话变量的值。

我得到以下输出：

有人可以帮助我解决代码中的错误吗？

It's just a spelling mistake of your variable - "guest_email_id" while printing the session variable.

request.session["guest_email_id"] = new_guest_user.id
print(new_guest_user.id)
print(request.session.get('guest_email_id'))
