    email = forms.EmailField(required=True)
    password = forms.CharField(required=True,min_length=5)
    captcha = CaptchaField(error_messages={'invalid':u'验证码错误'})

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()
        if register_form.is_valid():
            user_name = request.POST.get("username", '')
            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()
