TypeError：save（）缺少1个必需的位置参数：“ self”

这是意见

class RegisterView(View):
def get(self,request):
    register_form = RegisterForm()
    return render(request,'register.html',{'register_form':register_form})
def post(self,request):
    register_form = RegisterForm(request.POST)
    if register_form.is_valid():
        user_name = request.POST.get("email", '')
        pass_word = request.POST.get("password", '')
        user_profile = UserProfile
        user_profile.username = user_name
        user_profile.email = user_name
        user_profile.password = make_password(pass_word)
        user_profile.save()   #error
        send_register_email(user_name,"register")

我想将user_profile保存到mysql，但是user_profile.save（）出错，TypeError：save（）缺少1个必需的位置参数：'self'，我应该如何解决？
