django-nocaptcha-recaptcha 总是显示额外的验证框

Question

我安装了django-nocaptcha-recaptcha 并将其集成到我的表单中：

from nocaptcha_recaptcha.fields import NoReCaptchaField

class ClientForm(forms.ModelForm):
    captcha = NoReCaptchaField()

它在表单上显示得很好，但是每当我点击它时，就会弹出一个额外的对话框，要求输入一些文本并进行验证。每次都会发生。我在另一个网络上的另一台计算机上对其进行了测试，单击该框后它仍然要求进行额外的验证。

这就是它的样子：additional verification dialog box

这是我处理表单的方式：

@xframe_options_exempt
def registration(request):           
    if request.method == 'POST':        
        clientform = ClientForm(request.POST)

    # check whether it's valid:
    if clientform.is_valid():
        new_client = clientform.save()
...

我做错了什么？ django-nocaptcha-recaptcha 有问题吗？我应该使用其他东西吗？

附：我正在使用 django 1.7.1 和 python 3.4

Another alternative：极简主义和非框架依赖。 这是代码，如果你想重写它。

重新启动服务器，不要忘记清除浏览器的缓存。希望这会有所帮助。
