得到这个 TypeError: is_valid() missing 1 required positional argument: 'self'

Question

我收到类型错误： is_valid() 缺少 1 个必需的位置参数：'self'

请纠正我做错的地方

def register(request):
registered = False

if request.method == "POST":
    user_form = UserForm(request.POST)
    profile_form = UserProfileInfoForm(request.POST, request.FILES)

    if user_form.is_valid() and UserProfileInfoForm.is_valid():
        user = user_form.save()
        user.set_password(user.password)
        user.save()

        profile = profile_form.save(commit=False)
        profile.user = user

        if 'profile_pic' in request.FILES:
            profile.profile_pic = request.FILES['profile_pic']

        profile.save()
        registered = True

    else:
        print(user_form.errors, profile_form.errors)

else:
    user_form = UserForm()
    profile_form = UserProfileInfoForm()

return render(request, 'basic_app/registration.html',
              {'user_form': user_form, 'profile_form': profile_form, 'registered': registered})

你忘了参加instance类。但是，你使用了类。所以，这样做：

if user_form.is_valid() and profile_form.is_valid():
