    email = forms.EmailField(required=True)
    password = forms.CharField(required=True, min_length=5)
    captcha = CaptchaField(error_messages={"invalid": u"驗證碼錯誤"})

• views.py代碼

from django.views.generic.base import View

class RegisterView(View):

    def get(self, request):
        register_form = RegisterForm()
        return render(request, "register.html", {"register_form": register_form})

• html頁面引用

{{ register_form.captcha }}
