引用

新建forms.py

from captcha.fields import CaptchaField

class RegisterForm(forms.Form):
    email = forms.EmailField(required=True)
    password = forms.CharField(required=True, min_length=6)
    captcha = CaptchaField(error_messages={"invalid": u"验证码错误"})

models.py
直接验证表单是否通过，验证码字段会一并校验。

class RegisterView(View):
    def get(self, request):
        register_form = RegisterForm()
        return render(request=request, template_name='register.html', context={"register_form": register_form})

    def post(self, request):
        register_form = RegisterForm(request.POST)
        if register_form.is_valid():
            user_profile = UserProfile()
            user_name = request.POST.get('username', '')
            pass_word = request.POST.get('password', '')
            user_profile.username = user_name
            user_profile.email = user_name
            user_profile.password = make_password(password=pass_word)
        else:
            return render(request=request, template_name='register.html', context={"register_form": register_form})
