How to validate Google reCAPTCHA v2 in django

I have been trying to use the Google reCAPTCHA on a website that I've been making. The captcha loads on the webpage but I've been unable to validate it using several methods. I've tried the recaptcha validation using the method given at How to use Python plugin reCaptcha client for validation? but I think it's outdated as it no longer works and it is referring to challenges whereas the one I'm trying to use is the new 'checkbox' reCAPTCHA v2 by Google or maybe I need to make changes in my settings after installing recaptcha-client or django-recaptcha.

Please help!

Solution

There is a third-party Django app to implement the new reCAPTCHA v2 here:

https://github.com/ImaginaryLandscape/django-nocaptcha-recaptcha

After installing it, add the following lines to the following files:

# settings.py
NORECAPTCHA_SITE_KEY = <the Google provided site_key>
NORECAPTCHA_SECRET_KEY = <the Google provided secret_key>

INSTALLED_APPS = (
    ....
    'nocaptcha_recaptcha'
)


#forms.py
from nocaptcha_recaptcha.fields import NoReCaptchaField

class YourForm(forms.Form):
    .....
    captcha = NoReCaptchaField()


# In your template, add the following script tag:
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
