Python 将django recaptcha添加到注册表时出现问题

我在注册表格中添加django recaptcha时遇到问题。该表格是django注册表格的扩展。以下是我如何将其插入（仅显示相关代码）：

URL.py：

*注册_custom.forms.py：*

from captcha.fields import ReCaptchaField 

class RegistrationFormUniqueEmail(RegistrationForm):
    """
    Subclass of ``RegistrationForm`` which enforces uniqueness of
    email addresses.

    """
    # added recaptcha
    captcha = ReCaptchaField()

    def clean_email(self):
        """
        Validate that the supplied email address is unique for the
        site.

        """
        if User.objects.filter(email__iexact=self.cleaned_data['email']):
        raise forms.ValidationError(_("This email address is already in use. Please supply a different email address."))
        return self.cleaned_data['email']

我已经检查了我的recaptcha密钥是否正确，它们是否正确，并且这些密钥是为我用来测试的域设置的

你能发现我错过了什么吗？谢谢。

您是否已将recaptcha添加到已安装的应用程序中？确切的问题是什么？已将“验证码”添加到已安装的应用程序中；问题是表单上没有显示recaptcha。

from captcha.fields import ReCaptchaField 

class RegistrationFormUniqueEmail(RegistrationForm):
    """
    Subclass of ``RegistrationForm`` which enforces uniqueness of
    email addresses.

    """
    # added recaptcha
    captcha = ReCaptchaField()

    def clean_email(self):
        """
        Validate that the supplied email address is unique for the
        site.

        """
        if User.objects.filter(email__iexact=self.cleaned_data['email']):
        raise forms.ValidationError(_("This email address is already in use. Please supply a different email address."))
        return self.cleaned_data['email']
