How to integrate google reCAPTCHA with django ?

step 1 .  Install django-nocaptcha-recaptcha in your Virtual Environment

              pip install django-nocaptcha-recaptcha

step 2 . Configuration

          Add nocaptcha_recaptcha to your INSTALLED_APPS setting

          Add the following to settings.py

         Required settings:

         NORECAPTCHA_SITE_KEY  (string) = the Google provided site_key
         NORECAPTCHA_SECRET_KEY (string) = the Google provided secret_key

         reffer  this link : https://developers.google.com/recaptcha/intro


        Add the field to a form that you want to protect.

        from nocaptcha_recaptcha.fields import NoReCaptchaField

         class DemoForm(forms.Form):

                captcha = NoReCaptchaField()


       Add Google's JavaScript library to your base template or elsewhere, so it is available on the page        containing the django form.

      <script src="https://www.google.com/recaptcha/api.js" async defer></script>
 
      (optional) You can customize the field.

      You can add attributes to the g-recaptcha div tag through the following

      captcha = NoReCaptchaField(gtag_attrs={'data-theme':'dark'}))

      You can override the template for the widget like you would any other django template.
