Question

所以我在base.html上有一个注册，然后表单重定向到注册页面。

def signIn(request):
    if request.user.is_authenticated():
        context = {
            "extendVar":"baseLoggedIn.html",
        }
        return HttpResponseRedirect("out")
    if request.user.is_authenticated()==False:
        # form=SignUpForm(request.POST or None)
        if request.method=="POST":

            email=request.POST.get('email','')
            password = request.POST.get('password','')

            user = auth.authenticate(username=email,password=password)

            print(email)
            print(password)
            print(user)
            if user is not None:
                print("notNone")
                auth.login(request,user)
                return HttpResponseRedirect("out")
            else:
                print("None quàlol")
                context={
                    "failure":"Password and e-mail did not match",
                }
                return HttpResponseRedirect("out") #redirects to base.html
        context = {
            "extendVar":"baseNotLoggedIn.html",
        }
    return render(request, "base.html",context)

唯一的问题是，当我这样做时，它重定向到主页，但主页没有任何错误，我无法找到一种方法来显示密码+电子邮件所做的错误不相符，因为我正在重定向。

您需要将消息作为上下文的一部分传递，而HttpResponseRedirect不会将任何上下文作为参数，因此您需要return render(request, "base.html", context)而不是HttpResponseRedirect。然后，您可以从"failure"访问context密钥。

另外，请保持代码清洁！

def sign_in(request):
    if request.user.is_authenticated():
        context = {
            "extendVar":"baseLoggedIn.html",
        }
        return HttpResponseRedirect("out")
    else:
        if request.method == "POST":
            form = SignUpForm(request.POST)
            if form.is_valid():
                email = form.cleaned_data['email']
                password = form.cleaned_data['password']

                user = auth.authenticate(username=email, password=password)

                print(email)
                print(password)
                print(user)
                if user:
                    print("notNone")
                    auth.login(request, user)
                    return HttpResponseRedirect("out")
                else:
                    print("None quàlol")
                    context={
                        "failure":"Password and e-mail did not match",
                    }
                    return render(request, "base.html", context)
            else:  # form invalid, pass as variable back to user with form errors
                return render(request, "base.html", {'form': form}
        context = {
            "extendVar":"baseNotLoggedIn.html",
        }
    return render(request, "base.html",context)

如何使用重定向传递变量？
